Preparing for a company's first external audit can feel overwhelming, but breaking it down into a structured timeline and focusing on core readiness areas will make the process smooth.
Here is a step-by-step roadmap for a Controller to lead the charge:
Establish the Audit Timeline and Project Management
Kickoff Meeting: Hold an alignment meeting with the audit partner and senior team to agree on the timeline, milestones, and deliverables.
Project Management Tool: Use a shared tracker (like Asana, Excel, or a dedicated audit management tool) to assign owners and deadlines for every single Prepared-by-Client (PBC) request.
Reconstruct and Clean Up the General Ledger
Balance Sheet Reconciliation: Every single balance sheet account (cash, AR, inventory, prepaid expenses, fixed assets, accruals, debt) must have a complete, documented reconciliation as of the audit date. No exceptions.
Cutoff Testing: Ensure transactions are recorded in the correct period, especially around year-end (revenue recognition and expense accruals).
Document Internal Controls and Processes
Process Narratives: Write down or update accounting policies and process flows for key cycles (Revenue/Cash Receipts, Purchasing/Cash Disbursements, Payroll, Financial Reporting).
Segregation of Duties: Identify any areas where one person has too much control (e.g., entering bills and signing checks) and document mitigating controls or workarounds.
Question: What is the best way for a Controller to prepare for the company's first external audit?
For a Controller preparing for the company’s first external financial statement audit, the biggest objective is to make the audit predictable: clean books, documented accounting decisions, organized support, and no surprises.
A practical approach is to work backward from the auditor’s expected evidence rather than simply waiting for the PBC (“provided by client”) list. AICPA guidance emphasizes planning ahead and communicating expectations, while audit standards focus heavily on sufficient evidence, opening balances, significant accounts, estimates, and controls.

A Controller preparing for the company’s first external audit should treat it as a project to build audit readiness, not just a scramble to gather documents. The goal is to give auditors confidence that the financial statements are accurate, supported, and produced through reliable processes.
1. Start with an audit kickoff and project plan
Before fieldwork begins:
Confirm the audit scope, reporting period, accounting framework (for example, GAAP), deadlines, and deliverables with the audit firm.
Establish a single point of contact (usually the Controller) for coordinating requests.
Create an audit timeline with owners, due dates, and status tracking.

Preparing for a company's first external audit can feel overwhelming, but breaking it down into structured, systematic phases makes it manageable. Here is a step-by-step roadmap for a Controller to lead the charge successfully:
Understand the Audit Scope and Timeline
Scope alignment : Meet with the external audit partners early to define the scope, materiality thresholds, and reporting deadlines.
Audit plan : Request a detailed PBC (Provided by Client) list and timeline so you can reverse-engineer deadlines for your internal team.
Conduct a Clean-Up of the Balance Sheet
Reconciliations : Ensure every single balance sheet account (cash, AR, inventory, prepaid expenses, fixed assets, accruals, debt) has a complete, dated reconciliation supported by documentation.

For a Controller preparing for the company’s first external audit, the best approach is to treat it as an audit-readiness project, not simply a year-end accounting exercise. The goal is to make sure the books are supportable, controls are documented, and every significant balance can be explained with evidence.
1. Start with the audit scope and expectations
Meet with the external auditor early—ideally several months before year-end—and establish:
Audit timeline and key deadlines
Applicable accounting framework (e.g., U.S. GAAP)
Materiality expectations
Significant accounts and risk areas
Expected audit requests/PBC ("prepared by client") list
Whether the audit includes an assessment/testing of internal controls
Required schedules, confirmations, legal letters, and management representations
For an initial audit, opening balances can receive particular attention because the auditor has no prior-year audited financial statements to rely on.
Question: What is the best way for a Controller to prepare for the company's first external audit?
Preparing for a company's first external audit can feel like standing at the base of a massive mountain, but breaking it down into structured phases makes it completely manageable. As a Controller, your main goal is to shift the company from "we track things internally" to "we can independently prove every single number."

For a Controller preparing for the company’s first external audit, the goal is not just to “get documents ready”—it is to demonstrate that the company has reliable financial records, repeatable processes, and evidence that controls are operating. A first audit is much smoother when preparation is treated as a project with owners, timelines, and deliverables.
1. Start with an audit readiness assessment
Before the auditors arrive, perform an internal gap review:
Are all balance sheet accounts reconciled?
Can every significant account balance be traced to supporting documentation?
Are accounting policies documented?
Are unusual transactions identified and explained?

Preparing for a company's first external audit can feel overwhelming, but breaking it down into a structured, phased approach makes it manageable. As a Controller, your main job is to shift the organization from an internal mindset to an evidence-based, transparent compliance mindset.
Here is a step-by-step roadmap to get audit-ready:
Establish the Audit Timeline and Scope
Set the audit kickoff date , interim testing windows, and final report delivery deadlines with your chosen CPA firm.
Clarify the scope of the audit (e.g., full GAAP financial statements vs. specific accounts) and confirm materiality thresholds.
Build a master request list (PBC list - Provided by Client) project tracker and assign owners for every item.
Digital Data Room: Set up a secure, logically structured cloud folder (like SharePoint, Box, or Datasite) with clear naming conventions for auditors.
Supporting Documentation: Ensure every sample item requested by auditors has a clear "audit trail"—from invoice to approval, payment, and posting.
Focus on High-Risk and Complex Areas Early
Revenue Recognition: Be ready to prove when and how revenue is earned under ASC 606 (or local GAAP equivalents), especially for multi-element or deferred revenue contracts.
Valuation & Estimates: Document the methodology behind subjective estimates, such as the Allowance for Doubtful Accounts, inventory obsolescence, or capitalized R&D.
Prepare the Financial Statement Draft and Disclosures
Draft Statements: Prepare clean financial statements (Balance Sheet, Income Statement, Cash Flow Statement) alongside a trial balance well before fieldwork begins.
Footnote Disclosures: Draft all required financial statement footnotes ahead of time, as these often take longer than expected to compile.
Manage the Audit Team On-Site/Remotely
Single Point of Contact (SPOC): Route all auditor questions through one person (usually the Controller or an Accounting Manager) to prevent conflicting answers and fatigue across other departments.
Daily/Weekly Syncs: Hold 15-minute stand-up meetings with the audit team to unblock stalled requests and address emerging issues immediately.
If you'd like, let me know:
What industry is your company in?
Is this a financial statement audit or a specialized review?
I can provide a tailored PBC checklist or focus on high-risk areas specific to your business model.
1. Get the books completely audit-ready
Before the auditors arrive, make sure:
All balance-sheet accounts are reconciled to supporting detail.
Bank, credit-card, AR, AP, payroll, debt, fixed assets, and intercompany accounts tie out.
The subledger agrees to the general ledger.
All material reconciling items are investigated and resolved.
The year-end close is substantially complete.
Suspense, clearing, and miscellaneous accounts are cleaned up.
Retained earnings/equity rolls forward correctly.
The trial balance agrees to the financial statements.
Don't give the auditors a moving target. A first audit becomes much harder when the GL continues changing materially throughout fieldwork.
2. Build an audit binder/data room
Create a logical folder structure before the PBC requests start coming in.
For every significant balance, ideally you should be able to answer:
What is the balance? How was it calculated? What supports it? Who reviewed it?
That mindset is extremely useful during a first audit.
3. Identify the high-risk accounting areas early
Don't wait for the auditor to discover your complicated accounting.
Make a list of transactions and balances involving significant judgment, such as:
Revenue recognition
Stock-based compensation
Business combinations
Debt and financing arrangements
Leases
Goodwill/intangibles
Inventory valuation
Bad-debt reserves
Accrued liabilities
Deferred revenue
Income taxes
Related-party transactions
Going-concern considerations
Litigation/contingencies
Fair-value measurements
Prepare an accounting memo for each material or complicated issue explaining:
The facts
The applicable accounting guidance
The company's analysis
The conclusion
Supporting documentation
This can save substantial time because auditors otherwise have to reconstruct the reasoning themselves.
4. Pay particular attention to opening balances
Because this is the first audit, opening balances are especially important. Auditing standards specifically require additional consideration in an initial audit to obtain sufficient appropriate evidence concerning opening balances.
Therefore, collect support for the beginning-of-period balances—not just the current-year activity.
For example:
Prior-year financial statements
Prior tax returns
Bank statements
Debt agreements
Fixed-asset records
Historical AR/AP aging
Inventory records
Equity records
Major contracts
Acquisition documentation
Prior accounting workpapers, if available
If there was a predecessor accounting firm, determine what historical documentation can legitimately be obtained and shared with the new auditors.
5. Document your internal controls
Even if you're a relatively small private company, don't assume the auditor only cares about the financial statements.
Prepare basic documentation for key processes:
Order-to-cash
Procure-to-pay
Payroll
Treasury/cash
Fixed assets
Inventory
Financial close
Journal entries
Revenue
Equity
IT/access controls
For each important control, document:
Who performs it → What they do → How often → What evidence they retain → Who reviews it
For example:
Controller prepares monthly bank reconciliation → CFO reviews and signs off → reconciliation and evidence of review retained in monthly close folder.
Auditors evaluate controls relevant to financial reporting and may test both their design and operation, particularly when an internal-control audit is involved.
6. Do your own "mock audit"
This is probably the highest-value exercise you can do.
Take your trial balance and pretend you're the auditor.
For every material account, ask:
"If I were an independent auditor, what evidence would I need to prove this balance?"
Then assemble it.
For example:
Account
What I'd expect to have ready
Cash
Bank statements + reconciliations + confirmations support
Cap table + agreements + board/shareholder documentation
Taxes
Returns + tax provision/reconciliation
Leases
Agreements + lease calculations
Contingencies
Legal correspondence + management assessment
This exercise will expose gaps before the auditor does.
7. Review cutoff carefully
First audits frequently generate questions around whether transactions belong in the correct period.
Do extra work around:
Revenue immediately before/after year-end
Shipments
Customer invoices
Vendor invoices received after year-end
Goods received but not invoiced
Payroll/accruals
Credit memos
Returns
Prepayments
Large journal entries around year-end
Have your own cutoff analysis ready rather than reconstructing it after the auditor asks.
8. Prepare the PBC tracker
Don't manage audit requests through email alone.
Use a tracker like:
| Request | Owner | Due | Status | Location
--- | --- | --- | --- | --- | ---
1 | Bank confirmations | Controller | 10/5 | Complete | Data room
2 | AR aging | AR Manager | 10/5 | Complete | Data room
3 | Revenue contracts | Revenue Lead | 10/7 | Open | —
4 | Debt agreements | Controller | 10/7 | Open | —
Have one person—ideally the Controller—own the tracker.
Also establish a rule that business owners don't independently send auditors documents without the accounting team knowing what was provided.
9. Meet with the auditors before fieldwork
Have a kickoff meeting covering:
Audit timeline
Year-end close date
PBC list
Materiality
Significant accounts
Key accounting judgments
Expected sampling
Confirmations
Inventory observation
Management representation letter
Audit adjustments
Communication process
Expected deliverables
Who on your team owns each area
AICPA guidance specifically recommends planning ahead and communicating with everyone involved in the audit process.
10. Tell the auditors about problems early
This is one of the most important Controller lessons.
If you discover:
A reconciliation error
A missing contract
An incorrect accounting treatment
A control that wasn't performed
A significant prior-period error
A potential related-party transaction
An unusual transaction
Tell the auditors early.
Don't spend three weeks trying to make an issue disappear before mentioning it. The auditor will eventually ask, and late surprises can disrupt the entire audit.
A good 90-day preparation plan
90–60 days before fieldwork
Lock down accounting policies.
Identify significant accounting judgments.
Perform a balance-sheet cleanup.
Document key processes and controls.
Identify historical/opening-balance gaps.
Discuss unusual transactions with the auditors.
Establish the PBC structure.
60–30 days before fieldwork
Complete account reconciliations.
Prepare accounting memos.
Assemble supporting schedules.
Perform preliminary analytical review.
Test key controls internally.
Resolve known deficiencies.
Prepare confirmation information.
30–0 days
Complete the close.
Tie the financial statements to the GL.
Perform your mock audit.
Finalize PBC documentation.
Review subsequent events.
Make sure everyone understands who communicates with the auditors.
During the audit
The Controller should function as the audit project manager, not merely the person answering accounting questions.
Track every request, control document flow, coordinate subject-matter experts, review proposed adjustments, and keep management informed of emerging issues.
The goal isn't to make the company look perfect. It's to make the company's accounting, judgments, controls, and supporting evidence understandable and traceable.
One particularly useful principle is: don't prepare for the PBC list; prepare for the auditor's questions. The PBC list is only the starting point.

One particularly useful principle is: don't prepare for the PBC list; prepare for the auditor's questions. The PBC list is only the starting point.
For a Controller preparing for a company’s first external financial statement audit, the biggest mistake is treating it as a year-end document-gathering exercise. The best approach is to build an audit-ready financial reporting process before the auditors arrive.
1. Agree on the audit scope and timeline early
Meet with the audit partner/manager well before year-end and establish:
Which financial statements and periods are being audited
Applicable accounting framework (e.g., U.S. GAAP)
Key accounting areas they expect to focus on
Materiality and significant-risk areas
Required schedules and supporting documentation
Interim vs. year-end testing
PBC (“prepared by client”) request dates
Expected fieldwork and reporting dates
Who on your team owns each request
For a first audit, the auditor also has additional work around opening balances, so historical records deserve particular attention.
2. Get the books completely clean
Before worrying about sophisticated controls, make sure the underlying accounting is defensible.
I would have the Controller drive a comprehensive balance-sheet reconciliation project:
Bank and investment accounts
AR and allowance for doubtful accounts
AP and accrued liabilities
Payroll and payroll taxes
Fixed assets and depreciation
Debt and interest
Equity/capital accounts
Inventory, if applicable
Deferred revenue/revenue recognition
Prepaids and other assets
Taxes
Intercompany balances
Every material balance should tie to the general ledger and have a reconciliation explaining what it represents and how it was substantiated. Audit-readiness guidance specifically emphasizes organized reconciliations and schedules that reconcile to the trial balance.
3. Create an accounting-policy file
Document the company's accounting conclusions for areas requiring judgment, rather than waiting for the auditor to ask.
At minimum, address:
Revenue recognition
Capitalization vs. expense
Fixed assets
Leases
Stock compensation
Debt
Allowances/reserves
Intangible assets
Related parties
Taxes
Going concern, if relevant
Subsequent events
Significant estimates
For each significant judgment, retain the analysis, assumptions, supporting evidence, and conclusion.
This is particularly valuable in a first audit because auditors will be developing their understanding of the business and its accounting at the same time.
4. Document the key processes and controls
Create simple process narratives or flowcharts for major cycles:
Order-to-cash
Procure-to-pay
Payroll
Treasury
Financial close
Fixed assets
Revenue
Equity
Financial reporting
For each important control, identify:
Risk → Control → Owner → Frequency → Evidence → Reviewer
For example:
Risk: Unauthorized payments
Control: CFO reviews and approves payment run
Frequency: Weekly
Evidence: Approved payment report
Reviewer: Controller
Don't create controls merely because they sound good. The control should actually operate consistently and leave evidence behind.
If the company is subject to an ICFR audit, the auditor's work is explicitly focused on the design and operating effectiveness of relevant controls.
5. Do a mock audit
This is probably the highest-value preparation exercise.
Take your top 10–20 significant accounts and pretend the auditor has asked:
"Prove this balance to me."
For each account, assemble the exact evidence you'd provide.
Then test questions such as:
Can we reproduce this number?
Does the supporting schedule tie to the GL?
Can someone other than the preparer explain it?
Is there evidence of review?
Are unusual transactions documented?
Can we explain every material fluctuation?
Can we produce the underlying contracts/invoices/reports quickly?
Anything that produces scrambling, reconstruction, or "I think that's in someone's email" becomes a remediation item.
6. Establish a PBC system
Don't let audit requests become dozens of emails.
Create a centralized tracker with columns such as:
Request
Owner
Due date
Status
Reviewer
Evidence location
Auditor response
Bank confirmations
Treasury
1/15
In progress
Controller
Audit folder
—
Give the audit team read-only access to a well-organized electronic data room if appropriate.
AICPA guidance emphasizes planning ahead, allocating staff capacity, and maintaining clear communication with the audit team.
7. Identify problems before the auditor does
Create a confidential audit issues log covering:
Known GAAP departures
Unsupported balances
Late reconciliations
Control failures
Unusual transactions
Related-party transactions
Significant estimates
Potential fraud risks
Prior-period errors
Missing documentation
Then determine which items need correction before year-end versus disclosure or discussion with the auditors.
The objective isn't to hide problems from the auditors. It's to ensure management discovers and understands them first.
8. Get the close under control
A first audit becomes painful when the underlying month/year-end close is still chaotic.
Ideally, before the audit begins, you have:
A documented close checklist
Clear account ownership
Standard reconciliation templates
Review sign-offs
Defined cutoff procedures
Journal-entry approval
Analytical review of financial statements
Variance explanations
A documented process for subsequent events
The AICPA recommends devoting additional time around year-end close and planning for audit fieldwork in advance.
9. Prepare management and the rest of the company
The Controller shouldn't be the only person who knows what's happening.
Brief executives and relevant employees on:
What an external audit is
What auditors can request
Who is authorized to respond
Why documentation matters
Why employees should answer questions honestly and completely
How requests should be routed
Auditors commonly interview personnel and assess processes and controls, not simply inspect accounting reports.
10. Keep the auditor informed—especially about surprises
Don't wait until fieldwork to disclose something significant.
Tell the audit team promptly about:
Acquisitions
New debt
Major contracts
Significant customers
Lawsuits
Financing transactions
Equity transactions
Accounting-system changes
Control failures
Potential errors
Major changes in estimates
Early communication gives both sides time to resolve complicated accounting questions rather than discovering them when the audit report is due.

Maintain a daily status meeting with the audit team if necessary
The Controller's core objective
Think of the job as creating an audit trail from transaction → GL → reconciliation → financial statement → supporting evidence → control/review.
If you can make that chain work consistently, the first audit becomes substantially more manageable. If you can't, adding more spreadsheets at year-end usually just creates more work.
One important caveat: the exact preparation depends heavily on whether this is a private-company financial statement audit, an SEC/public-company audit, or a specialized audit. Public-company audits can involve additional ICFR requirements and PCAOB standards; the PCAOB's standards specifically address both financial-statement audit planning and, where applicable, integrated ICFR audits.
Review your current financial statements, accounting policies, and internal controls to identify any gaps against GAAP or IFRS standards.
Pinpoint high-risk areas like revenue recognition, inventory valuation, and complex debt or equity instruments.
Establish the Audit Timeline and Team
Partner with the audit firm to set a clear project plan, including interim testing, year-end fieldwork dates, and a final delivery deadline.
Assign internal roles and responsibilities so every ledger, reconciliation, and PBC (Provided by Client) item has a clear owner.
Clean Up the General Ledger and Balance Sheet
Perform a rigorous, formal review of all balance sheet accounts and ensure every single one has an up-to-date, signed-off reconciliation.
Clear out old open items in clearing accounts, unapplied cash, and suspense accounts well before the auditors arrive.
Prepare the PBC (Provided by Client) Request List
Anticipate the auditor's data requests—such as bank confirmations, fixed asset schedules, payroll reports, and major contract samples.
Create a centralized, secure digital data room (like Google Drive, SharePoint, or an audit portal) and organize files using a clean, intuitive folder structure that mirrors the PBC list.
Document Internal Controls and Processes
Write down key financial workflows, especially around cash disbursements, revenue generation, journal entry approvals, and financial close procedures.
Ensure segregation of duties is documented, or compensating controls are in place where the team is small.
Draft Financial Statements and Disclosures Early
Do not wait for the auditors to draft your financial statements or footnote disclosures; put together a pro-forma draft complete with statements of cash flows and comprehensive footnotes.
Reconcile all footnote numbers back to the trial balance ahead of time.
Establish Clear Communication Protocols
Designate a single point of contact (usually yourself or a senior accounting manager) to field auditor questions to prevent conflicting information or message fatigue across departments.
Schedule weekly check-ins during fieldwork to review open items, roadblocks, and emerging issues.
Would you like me to help you draft a sample PBC (Provided by Client) checklist or focus on best practices for managing the auditor relationship during fieldwork?
Schedule regular check-ins with the auditors during preparation and fieldwork.
A simple tracker should include:
Item
Owner
Due Date
Status
Bank reconciliations
Treasury/Accounting
Jan. 15
Complete
Revenue support
Controller
Jan. 20
In progress
Fixed asset roll-forward
Accounting Manager
Jan. 25
Pending
2. Clean up the books before auditors arrive
Auditors will spend significant time testing account balances. Make sure:
All balance sheet accounts are reconciled.
Bank reconciliations are complete and reviewed.
Intercompany balances agree.
Old reconciling items are investigated and cleared.
Accruals, prepaid expenses, fixed assets, debt, leases, and equity accounts have supporting schedules.
The trial balance ties to the financial statements.
A first audit often exposes gaps where companies have the accounting entries but lack documentation proving why those entries are correct.
3. Build an organized audit support package
Create a structured audit folder (preferably with consistent naming conventions):
Trial balance and general ledger detail
Financial statements and disclosures
Account reconciliations
Bank statements and confirmations
Customer/vendor contracts
Debt agreements
Lease agreements
Fixed asset listings
Payroll records
Tax filings
Board minutes and major transaction approvals
The key question: “If an auditor asks for support, can someone find it within minutes?”
4. Document accounting policies and significant judgments
First-time audits frequently uncover areas where accounting decisions were made informally.
Document policies for areas such as:
Revenue recognition
Expense capitalization
Inventory valuation
Bad debt reserves
Stock compensation
Leases
Software development costs
Estimates and reserves
Also prepare a list of unusual or significant transactions during the year and the accounting conclusions reached.
5. Evaluate internal controls
Auditors will want to understand how financial information is created and protected.
Review:
Who can create, approve, and post journal entries
User access to accounting systems
Approval workflows
Segregation of duties
Close procedures
Review controls
If one person performs multiple roles (common in smaller companies), document compensating controls such as management review.
6. Prepare the accounting team for auditor interaction
Coach the team to:
Respond promptly and accurately.
Provide complete answers rather than partial information.
Avoid guessing—say “I’ll confirm and follow up.”
Maintain a log of documents provided and auditor questions.
Escalate potential issues early.
A collaborative relationship with auditors generally leads to a smoother engagement.
7. Perform a mock audit or readiness review
Before the auditors arrive:
Select major accounts and trace transactions from the ledger to supporting documents.
Review large or unusual journal entries.
Test whether reconciliations are complete.
Confirm that disclosures are supported.
Identify gaps and assign remediation owners.
This is especially valuable for a first audit because it reveals issues before they become audit findings.
8. Plan for the audit findings process
The first audit is not only about receiving an opinion; it is also about improving the finance function.
Prepare to:
Track proposed adjustments.
Document management decisions on audit recommendations.
Assign owners and deadlines for remediation.
Communicate significant issues to executives or the audit committee.
A practical 60–90 day preparation timeline
90+ days before fieldwork
Select audit firm and confirm scope.
Hold planning meeting.
Identify high-risk accounting areas.
Begin reconciliation cleanup.
60 days before fieldwork
Complete major schedules.
Draft financial statements.
Gather contracts and supporting documentation.
Review controls.
30 days before fieldwork
Finalize PBC (Prepared By Client) list.
Resolve open accounting issues.
Perform mock audit procedures.
During fieldwork
Maintain daily communication.
Track requests and deadlines.
Resolve questions quickly.
Document decisions.
The strongest first audits usually come from a Controller who creates a repeatable process: clean books + organized evidence + documented controls + proactive communication.
Aging analysis : Review Accounts Receivable for collectibility (and ensure an adequate allowance for doubtful accounts) and Accounts Payable for unrecorded liabilities or old outstanding checks.
Establish Strong Internal Controls and Documentation
Segregation of duties : Review who has authorization, custody, and recording responsibilities, and document compensating controls if your team is small.
Approval workflows : Ensure all journal entries, major disbursements, and contract approvals have documented, sign-off trails.
Prepare the PBC Binder and Data Room
Virtual data room (VDR) : Organize files logically by financial statement line item or PBC item number. Clean naming conventions save hours of back-and-forth.
Audit trail : Keep source documents (invoices, bank statements, contracts, board minutes) easily accessible and cross-referenced to your trial balance.
Focus on Complex Accounting Areas Early
Revenue recognition : Document your revenue recognition policies (especially under ASC 606 if applicable) with contract samples.
Stock-based compensation and equity : Have a clean cap table, option agreements, and 409A valuations ready if you have issued equity.
Manage the Team and Auditor Relationship
Single point of contact : Act as the primary gatekeeper for all auditor requests to prevent team distraction and mixed messages.
Set expectations : Brief internal department heads on what data they will need to pull and when. Treat auditor questions with transparency and urgency.
If you'd like to dive deeper, let me know:
What industry is your company in?
What framework are you reporting under (GAAP, IFRS, or cash basis)?
What is your timeline until fieldwork begins?
2. Get the balance sheet "audit ready"
This is probably the Controller's highest-value task.
For every material balance-sheet account, prepare a reconciliation to the general ledger and supporting documentation. At minimum:
This becomes especially important if you're subject to an internal-control audit. Under PCAOB standards, auditors take a risk-based, top-down approach from financial-statement risks to significant accounts, assertions, and relevant controls.
5. Test your own controls before the auditors do
Don't merely document controls—operate and test them.
For example:
Monthly bank reconciliation → prepared by Accountant → reviewed by Controller → reviewer signs/dates → reconciling items investigated.
Then take several months of reconciliations and ask:
Was it performed?
Was it performed on time?
Is there evidence of review?
Were exceptions investigated?
Is the reviewer sufficiently independent?
Fix deficiencies before the audit. A control that exists on paper but wasn't actually performed is a common source of unpleasant audit findings.
6. Build an audit PBC binder/data room
Create a structured folder before the auditors arrive:
Use consistent file names and make sure the support ties exactly to the financial statements and GL.
7. Perform a "mock audit"
This is one of the best things a first-time Controller can do.
Take the top 10–20 material/risky accounts and pretend you're the auditor. For each one ask:
"How would I prove this balance is complete, accurate, properly valued, properly classified, and actually exists?"
Also perform:
Analytical review of P&L fluctuations
Gross-margin analysis
Working-capital analysis
Search for unrecorded liabilities
Subsequent-events review
Revenue cutoff testing
A/R collectibility review
Accrual completeness review
Related-party review
The objective is to identify surprises while you still have time to fix them.
8. Pay special attention to estimates and unusual transactions
Auditors tend to spend disproportionate time on areas involving judgment.
Flag things such as:
Revenue arrangements
Significant contracts
Customer credits/refunds
Bad-debt reserves
Inventory reserves
Bonuses
Litigation
Stock compensation
Impairments
Acquisitions
Related-party transactions
Debt modifications
Large or unusual journal entries
Have a written memo explaining the company's accounting conclusion and the evidence supporting it.
9. Establish a clean monthly close
A first audit becomes dramatically easier if the Controller can demonstrate that the company has a disciplined close process.
Ideally have:
Close checklist
Account reconciliations
Review/sign-off
Journal-entry approval
Variance analysis
Financial-statement review
Documented cutoff procedures
The auditor is ultimately looking for sufficient appropriate evidence, not just a spreadsheet that "looks right."
10. Manage the auditors proactively
Designate one person—usually the Controller—as the audit coordinator.
Have a tracker like:
PBC Item
Owner
Due
Status
Auditor Question
Resolution
Bank confirmations
Treasury
9/15

Don't let auditors receive five different versions of the same information from five employees.
And when you don't know the answer, don't guess. Tell the auditor you'll investigate and come back with documentation.
The Controller's "first audit" priority order
If time is limited, I'd prioritize it this way:
Make sure the financial statements and trial balance are correct.
Reconcile every material balance-sheet account.
Identify and resolve unusual transactions and accounting judgments.
Document key accounting policies.
Document and test key controls.
Build the PBC package/data room.
Perform a mock audit and close remaining gaps.
Establish a disciplined communication process with the auditors.
The biggest mistake is trying to make the company look audit-ready. The better objective is to make the underlying accounting provable. Effective internal control is ultimately about reasonable assurance that financial reporting is reliable and that the financial statements are prepared appropriately—not simply having policies sitting in a binder.
If this is a private company preparing for its first GAAP financial-statement audit, I can also give you a practical 90-day first-audit readiness checklist, including exactly what the Controller should prepare week by week.
Here is the best way to prepare, broken down into a clear, phased roadmap:
1. Pre-Audit Foundation & Planning (Months 1–3)
Select the Audit Firm: Choose a CPA firm that has experience in your specific industry. Ensure the engagement letter, timeline, and deliverables list (the PBC list—Provided by Client) are locked in early.
Establish the Audit Committee/Leadership Link: Set clear lines of communication between the external auditors, executive leadership, and the board (if applicable). Decide who the single point of contact (SPOC) will be—ideally, it's you or a dedicated accounting manager, but department heads should never talk to auditors unvetted.
Set the Timeline: Work backward from your target issuance date. Build in heavy buffers for messy data, unexpected adjustments, and team burnout.
2. Clean Up and Reconcile the Balance Sheet (Months 2–4)
Reconcile Every Account: Every single balance sheet account—cash, prepaid expenses, fixed assets, accrued liabilities, and equity—needs a current, dated reconciliation with backup documentation attached. No exceptions.
Bank & Subledger Confirmations: Ensure cash, debt, and AR/AP subledgers tie out cleanly to the general ledger control accounts.
Fix Historical Anomalies: Clean up old reconciling items, lingering suspense accounts, and misclassified expenses. Auditors will look closely at unusual or aged items sitting on the balance sheet.
Review Accounting Policies: Document your key accounting policies, especially around revenue recognition (under ASC 606 if US GAAP), inventory valuation, and capitalization.
Gather Contract Backups: Pull major customer contracts, vendor agreements, and lease agreements (ASC 842). Auditors will sample these to test cut-offs and obligations.
Roll-forward Schedules: Build clean Excel roll-forwards for Fixed Assets (depreciation schedules), Prepaids (amortization), and Accruals. Make sure the beginning balance + additions - deductions = ending balance matches the GL.
4. Internal Controls & Process Walkthroughs (Month 4–5)
Document Processes: Write down how transactions flow from initiation to financial statement posting. Auditors will conduct "walkthroughs"—picking a transaction and tracing it from start to finish.
Segregation of Duties: Identify any control gaps where one person has too much access (e.g., someone who can create a vendor and approve payments). Put compensating controls in place if your team is small.
Access Controls: Restrict financial system permissions so only authorized personnel can post journal entries or adjust master data.
5. Final Dry Run & PBC Delivery (1 Month Before Fieldwork)
Populate the PBC Room: Create a secure, organized data room (using a platform like ShareFile or Box ) structured neatly by audit request item numbers. Clean organization builds immediate auditor confidence.
Draft the Financial Statements: Prepare draft financial statements and footnotes ahead of time rather than waiting for the auditors to write or request them.
Mock Review: Review your own PBC items as if you were the auditor. Ask yourself: Does this file tell a complete, self-explanatory story?
If you'd like, let me know:
What industry is your company in?
Are you reporting under US GAAP, IFRS, or cash-basis?
Roughly how large is your transaction volume/team?
I can give you a more tailored PBC checklist or focus on specific revenue/inventory complexities you might face.
Are approvals and reviews evidenced?
Are there any “tribal knowledge” processes that only one person understands?
Create a list of gaps and assign:
Owner
Due date
Required evidence
Status
This becomes the Controller’s audit project plan.
2. Meet with the audit firm early
Schedule a planning meeting with the external auditors before fieldwork.
Align on:
Audit scope and reporting framework (for example, GAAP basis, statutory requirements)
Audit timeline
Key contacts
Materiality expectations
Areas of focus
Prepared-by-Client (PBC) request list
Data delivery methods
Avoid preparing for a generic audit; prepare for the specific procedures your audit firm plans to perform.
3. Clean up the accounting records
Auditors will start with the general ledger and trial balance. Make sure:
Balance sheet accounts
Bank accounts are reconciled
Accounts receivable aging agrees to the GL
Accounts payable aging agrees to the GL
Accruals are supported and reviewed
Prepaids are amortized correctly
Fixed assets reconcile to the asset register
Intercompany balances are resolved
Income statement accounts
Revenue is supported and properly cut off
Major expense accounts have explanations for unusual fluctuations
Significant estimates have documented calculations
Monthly reconciliation discipline is one of the strongest indicators of audit readiness.
4. Build an organized audit evidence repository
Create a folder structure before the audit begins, such as:
Auditors should not have to hunt through email chains to find evidence.
5. Strengthen journal entry controls
Expect auditors to test manual entries.
Make sure:
Entries have explanations
Supporting calculations are attached
Preparers and approvers are different people where possible
Non-routine entries receive additional review
Journal entry reports can be exported easily
Close Flow## 6. Document key processes and controls
Prepare short process narratives for areas such as:
Revenue cycle
Purchasing and payables
Payroll
Cash management
Month-end close
Financial reporting
Document:
Who performs each step
Who reviews it
What evidence proves the control occurred
Auditors are evaluating not only whether numbers are correct, but whether the company has a reliable process for producing them.
7. Identify high-risk areas before auditors do
Review transactions that may receive extra attention:
New contracts
Debt agreements
Equity issuances
Acquisitions
Large one-time expenses
Revenue arrangements
Related-party transactions
Significant estimates
Prepare explanations and supporting documents ahead of time.
8. Assign a single audit coordinator
The Controller should usually act as the central point of contact.
Maintain an audit tracker:
Request
Owner
Due Date
Status
Bank confirmations
Treasury
Date
Open
Revenue samples
Sales Ops
Date
Complete
Fixed asset rollforward
Accounting
Date
Pending
This prevents duplicate work and keeps leadership informed.
9. Prepare the accounting team for auditor interaction
Make sure staff understand:
Answer questions directly and factually
Do not guess—follow up if unsure
Provide requested support, not unnecessary extra information
Escalate judgment questions to the Controller
A calm, organized finance team builds auditor confidence.
10. Plan for the post-audit period
A first audit often produces improvement items. After completion:
Review audit adjustments
Document root causes
Create remediation plans
Assign owners and deadlines
Update procedures before the next audit
A successful first audit is not just a clean opinion—it is establishing a stronger finance function going forward.
Practical timeline
90–120 days before fieldwork
Select audit team contacts
Review prior financial statements
Identify accounting issues
Begin reconciliations and documentation
30–60 days before fieldwork
Complete major schedules
Draft financial statements
Resolve open accounting items
Finalize PBC materials
During fieldwork
Track requests daily
Respond quickly
Document decisions
Escalate issues early
After audit
Implement improvements
Update controls
Maintain audit-ready files monthly
The biggest mindset shift for a first-time Controller is: an audit is not a document collection exercise; it is a test of whether the company’s financial reporting process can be trusted.
Perform complete balance sheet reconciliations for every single asset and liability account as of the cutoff date. Cash, accounts receivable, inventory, and prepaid expenses need rock-solid backup schedules.
Review intercompany accounts to ensure they eliminate correctly if there are multiple entities.
Investigate and clear out any long-standing, unexplained suspense or clearing accounts.
Formalize Accounting Policies and Estimates
Document key accounting policies (revenue recognition, capitalization thresholds, inventory valuation) so the auditors understand your methodology.
Support all significant management estimates —like the allowance for doubtful accounts or warranty reserves—with documented, defensible calculation logic and historical data.
Organize the Audit Trail and Documentation
Create a secure, centralized shared drive structured logically by audit cycle (e.g., Cash, Revenue, Payroll, Fixed Assets) so you can easily grant and revoke auditor access.
Ensure every journal entry has a standard description, proper calculation backup, and dual-authorization sign-off.
Keep physical or digital copies of all key contracts (leases, debt agreements, major customer/vendor contracts) readily accessible.
Prepare the Financial Statements and Disclosures
Draft the balance sheet, income statement, statement of cash flows, and statement of stockholders' equity along with a comprehensive first draft of the footnotes.
Check that your financial statements comply with GAAP or IFRS requirements relevant to your industry.
Manage the Auditor Relationship
Designate one primary point of contact (ideally you or a senior accounting manager) to funnel all communication and document requests to prevent conflicting answers.
Schedule weekly check-in calls during the active audit to review progress, unblock bottlenecks, and manage emerging issues.
If you'd like, let me know:
What industry is your company in?
What accounting software are you using?
Have you already selected an audit firm?
I can provide tailored checklists or specific risks to watch out for based on your setup.
