We are evaluating acquisition targets. Who performs due diligence?

In an acquisition, the buyer is responsible for due diligence, but the actual work is usually divided among the buyer’s internal team and outside specialists. It is not typically one person or one firm doing everything.

Typical diligence team

Deloitte, for example, describes M&A diligence as spanning financial, tax, commercial, operational, HR, IT/cyber, regulatory and other workstreams.

Who coordinates it?

Usually the buyer’s deal team / corporate development team acts as the quarterback. They determine the scope, coordinate the advisors, consolidate findings, and ultimately answer:

“Given what we've learned, should we buy this company, at what price, and with what protections?” The investment banker may help coordinate the transaction, but generally isn't the primary diligence owner. The buyer's lawyers and financial advisors provide independent workstreams and findings.

For a smaller acquisition, you might have something as simple as:

CEO/owner + CFO + corporate development lead → M&A lawyer → CPA/financial diligence firm → tax advisor → technical/operational specialists as needed

For a PE-backed or larger strategic acquisition, there can be a much larger multidisciplinary diligence team.

One important distinction: due diligence is different from valuation. Financial diligence tests whether the target's financial claims are reliable; the buyer's deal/finance team then uses those findings, along with the market and strategic analysis, to determine what the company is actually worth and the maximum price they're willing to pay.

If you're building an acquisition process, I can also give you a practical M&A due-diligence checklist organized by who should perform each task, what documents to request, and the red flags to look for.

Evaluating an acquisition target requires a multidisciplinary team. Depending on the size of the deal and the resources of the acquiring company, due diligence is typically conducted by a combination of internal teams and specialized external advisors.

Here is a breakdown of who performs the various pillars of due diligence:

• Internal Corporate Development / M&A Team: Leads the overall process, coordinates the workflow, evaluates strategic fit, and handles high-level integration planning.
• Financial & Accounting Advisors (External CPAs/Firms): Conducts quality of earnings (QoE) analysis, reviews historical financial statements, audits tax compliance, and scrutinizes working capital.
• Legal Counsel (Internal and External Attorneys): Reviews corporate governance, material contracts, pending or historical litigation, intellectual property ownership, and regulatory/compliance history.
• Operational & Technical Specialists: Assesses supply chains, manufacturing facilities, operational bottlenecks, and physical or operational assets.
• IT & Cybersecurity Experts: Evaluates software architecture, tech stack scalability, data security protocols, and compliance with data privacy regulations (like GDPR or CCPA).
• Human Resources & Compensation Consultants: Analyzes organizational charts, employee benefit plans, key-person retention risks, labor union agreements, and cultural alignment.
• Environmental, Health, and Safety (EHS) Consultants: Evaluates regulatory compliance, potential site contamination, and workplace safety liabilities (crucial for manufacturing, energy, or real estate deals).

If you'd like, let me know:

• The industry or sector of your target company
• The approximate deal size or company stage (startup vs. enterprise)

I can provide a customized due diligence checklist tailored specifically to your evaluation.

When evaluating an acquisition target, a comprehensive due diligence process requires a multidisciplinary team . No single person or group can examine every angle—financial, legal, operational, and strategic—on their own.

The primary groups and professionals who perform due diligence include:

• Internal Deal Team / Corporate Development : The core in-house team leading the transaction, including corporate development executives, the CEO, and the CFO. They coordinate the overall process, manage the timeline, and evaluate strategic fit.
• Financial and Accounting Advisors : Typically external CPA firms or specialized consultants who perform financial due diligence (FDD). They audit historical financials, analyze quality of earnings (QoE), review working capital trends, and identify hidden liabilities or tax risks.
• Legal Counsel : Internal and external mergers and acquisitions (M&A) attorneys who review material contracts, corporate governance records, intellectual property ownership, pending litigation, and regulatory compliance.
• Operational and Technical Consultants : Specialists who assess IT infrastructure, cybersecurity posture , supply chain resilience, manufacturing facilities, and R&D capabilities to ensure there are no legacy technical debts or integration roadblocks.
• Human Resources and Compensation Experts : Professionals who evaluate employee contracts, pension liabilities, benefit plans , key retention risks, and cultural alignment between the two organizations.
• Commercial and Market Consultants : Industry experts or internal strategy teams who validate market size, competitive landscape , customer concentration, and top-line growth assumptions.

Provide a phase-by-phase due diligence checklist Break down the differences between buy-side and sell-side due diligence Outline the typical timeline for an M&A due diligence process

In an acquisition, the buyer is responsible for due diligence, but it is usually performed by a combination of the buyer’s internal team and outside specialists.

Typical allocation:

• Financial / Quality of Earnings: CPA, accounting, or transaction-advisory firm. They test revenue, EBITDA, working capital, debt, cash flow, accounting policies, and projections.
• Tax: Tax advisers, usually from an accounting/transaction-advisory firm, sometimes with tax attorneys.
• Legal: M&A attorneys review corporate records, contracts, litigation, IP, employment, regulatory compliance, and other liabilities.
• Commercial: Buyer’s strategy/business-development team, often supplemented by a consulting firm, evaluates market size, competition, customers, pricing, and the credibility of the growth plan.
• Operational: Buyer’s operating executives and/or an outside operations consultant assess processes, supply chain, facilities, technology, and integration requirements.
• IT / Cybersecurity: IT specialists or a specialized cybersecurity firm assess systems, architecture, security, data, and technology debt.
• HR / Benefits: HR specialists examine compensation, benefits, key employees, retention, employment agreements, and organizational issues.
• Environmental / Real Estate / Regulatory: Specialized consultants and attorneys are brought in when relevant.

The buyer’s deal team or M&A lead coordinates all of these workstreams and turns the findings into a recommendation: proceed, renegotiate price/terms, require protections such as indemnities or escrow, or walk away.

For a typical middle-market acquisition, think of it as:

Buyer/deal team → coordinates diligence → lawyers + accounting/tax firm + commercial/operational/technical specialists → findings feed valuation and purchase agreement.

If you're evaluating targets, I can also give you a practical M&A due-diligence team structure, including who you need in-house vs. which advisors to hire and typical fees.

In an acquisition, due diligence is usually performed by a cross-functional deal team led by the buyer, with support from outside specialists. The exact mix depends on the size, industry, and complexity of the target.

Typical participants include:

• Corporate development / M&A team — Owns the diligence process, coordinates workstreams, manages the data room, and synthesizes findings for executives or the investment committee.
• Finance team and transaction advisors — Perform financial due diligence, including quality of earnings, revenue and margin analysis, working capital, debt-like items, cash flows, and financial risks. External accounting/advisory firms are often engaged for this work.
• Legal counsel (internal and external M&A lawyers) — Conduct legal diligence, reviewing contracts, litigation, intellectual property, corporate records, regulatory matters, employment issues, and transaction risks.
• Tax advisors — Review tax filings, exposures, tax attributes, transaction structure, and potential tax liabilities.
• Business unit leaders / operating executives — Evaluate the target’s products, customers, operations, strategic fit, and integration feasibility.
• IT, cybersecurity, and technology specialists — Assess systems, software, data security, technical debt, and technology scalability.
• HR and benefits specialists — Review workforce, compensation, benefits, key employees, labor issues, and culture considerations.
• Industry or functional consultants — May perform commercial, market, operational, environmental, engineering, regulatory, or other specialized diligence.

For a typical acquisition process, the structure often looks like:

Investment committee / board → approves strategy and oversees risk

Corporate development / deal lead → manages the diligence process

Functional diligence teams → investigate their areas and report findings

External advisors → provide independent expertise and deeper analysis

The buyer is generally responsible for performing diligence, although sellers often prepare materials ("sell-side diligence") to make the process smoother, and in some transactions both parties conduct diligence.

If you are evaluating acquisition targets, a practical setup is usually a diligence checklist + workstream owners + red-flag report + valuation impact assessment before making a final investment decision.

When evaluating an acquisition target, a collaborative team of internal professionals, external specialists, and advisors performs due diligence. Because a comprehensive review covers financial, legal, operational, and strategic angles, no single department does it alone.

Here is a breakdown of who performs the different pillars of due diligence:

• Internal Deal Team / Corporate Development : The core internal group (often including the M&A director, corporate strategy team, and C-suite executives) oversees the entire process, coordinates the workflow, and synthesizes findings to make the final go/no-go recommendation.
• Financial & Tax Due Diligence Providers : Typically led by external accounting firms (such as the Big Four or regional CPAs) or internal finance teams. They audit historical earnings, quality of earnings (QoE), working capital trends, tax liabilities, and financial projections.
• Legal Counsel : External or internal corporate lawyers review material contracts, corporate governance records, pending or past litigation, intellectual property rights, compliance histories, and regulatory approvals.
• Operational & IT Specialists : Consultants or internal operations leaders inspect supply chains, manufacturing facilities, physical assets, cybersecurity posture, software architecture, and technical debt.
• Human Resources & Benefits Experts : Specialists evaluate organizational structures, key employee retention risks, cultural alignment, pension liabilities, and compensation or benefit plans.
• Commercial & Market Analysts : Market researchers or internal sales teams assess the target's competitive positioning, customer concentration, market share, and industry growth outlook.

You can check out guidance on managing these teams through resources like the Harvard Business Review or professional advisory frameworks on Deloitte Insights.

If you'd like, let me know:

• What industry or sector is the target company in?
• Is this an in-house team effort or are you looking to hire external advisors?

I can provide a more tailored due diligence checklist or a recommended timeline for the process.

In an acquisition, due diligence is usually performed by a cross-functional team led by the buyer. The exact team depends on the size and complexity of the transaction, but commonly includes:

• Corporate development or M&A team – Coordinates the overall due diligence process, manages timelines, and synthesizes findings into recommendations.
• Finance and accounting specialists – Review historical financial statements, earnings quality, working capital, cash flow, debt, tax exposures, and forecasts. This work is often supported by transaction advisory teams from accounting firms.
• Legal counsel – Examines contracts, litigation, intellectual property, employment matters, regulatory compliance, corporate governance, and transaction structure.
• Tax advisors – Assess tax liabilities, risks, and opportunities related to the acquisition.
• Operational and business leaders – Evaluate manufacturing, supply chain, sales, technology, cybersecurity, human resources, and integration risks. Their operational knowledge often identifies issues that financial reviews alone would miss.
• Technical or industry experts – For specialized businesses (e.g., healthcare, software, energy), subject-matter experts assess technology, regulatory, environmental, or scientific risks.
• External advisors – Investment bankers, consultants, valuation firms, and specialized diligence providers may assist with commercial due diligence, market analysis, valuation, negotiations, or specific risk assessments.

Typical areas of due diligence

The team generally investigates:

• Financial performance and accounting
• Legal and regulatory matters
• Tax
• Commercial and market position
• Operations and supply chain
• Technology and cybersecurity
• Human resources and employee benefits
• Environmental, health, and safety (where relevant)
• Intellectual property
• Integration planning

The goal is to verify the seller's claims, identify risks and liabilities, validate the purchase price, and determine whether to proceed, renegotiate, or abandon the transaction.

For smaller acquisitions, one accounting firm and one law firm may perform much of the work. For larger or private equity transactions, due diligence is often divided among multiple specialist teams working simultaneously.

Evaluating an acquisition target requires a multidisciplinary approach. Because due diligence covers every facet of a business—financial, legal, operational, and strategic—a combination of internal team members and external specialists is typically deployed.

• Internal Team:
  • Corporate Development / M&A Team : Owns the overall process, coordinates workstreams, synthesizes findings, and manages the timeline and communication with the target company.
  • C-Suite & Executive Leadership : Make the ultimate go/no-go decisions, negotiate key terms, and evaluate strategic and cultural fit.
  • Finance & Accounting Department : Conducts initial internal reviews of historical financials, builds valuation models, and works alongside external auditors.
  • In-House Legal Counsel : Reviews basic corporate records, flags obvious legal risks, and coordinates with outside legal advisors.
  • Functional Leaders (HR, IT, Sales/Marketing) : Evaluate integration challenges, department-specific systems, key personnel retention, and operational overlaps.
• External Advisors & Specialists:
  • Investment Bankers / Financial Advisors : Help structure the transaction, assist in valuation, and facilitate information flow through the data room.
  • Accounting/Audit Firms (Third-Party CPAs) : Perform formal Quality of Earnings (QoE) analysis, audit financial statements, assess tax compliance, and uncover hidden liabilities or working capital issues.
  • Legal Counsel (Outside Law Firms) : Conduct deep-dive legal due diligence (litigation history, intellectual property rights, contracts, regulatory compliance) and draft transaction agreements.
  • Technical / IT Consultants : Assess cybersecurity postures, software scalability, technical debt, and data privacy compliance (e.g., GDPR, CCPA).
  • Human Resources & Benefits Consultants : Evaluate compensation structures, pension liabilities, key employee retention risks, and cultural integration.
  • Environmental / Industry Specialists : Brought in for specialized asset-heavy or regulated sectors (like manufacturing, energy, or healthcare) to assess environmental liabilities or regulatory approvals.

If you'd like, let me know:

• What is the industry of your target company?
• Is this a strategic or private equity acquisition?

I can provide a more tailored due diligence checklist for your specific deal.

Evaluating an acquisition target requires a multidisciplinary team to ensure no stone is left unturned. Depending on the size of the deal and the company's resources, due diligence is typically performed by a combination of internal teams and external specialists.

Here is a breakdown of who handles the different pillars of the due diligence process:

• Corporate Development / M&A Team acts as the internal quarterback, coordinating the entire process, setting timelines, managing the data room, and synthesizing findings from all other workstreams.
• Financial and Accounting Advisors (often external CPAs or specialized transaction services firms) audit the target's financial statements, quality of earnings, working capital requirements, and tax compliance.
• Legal Counsel (internal and external attorneys) reviews contracts, corporate governance documents, pending or past litigation, intellectual property rights, and regulatory compliance.
• Operational and HR Specialists analyze organizational charts, employee compensation, benefit plans, key-person dependencies, IT infrastructure, supply chain stability, and operational efficiencies.
• Commercial and Market Consultants evaluate the target’s competitive landscape, market share, customer concentration, pricing power, and growth projections.
• Environmental, Health, and Safety (EHS) Experts (for manufacturing, industrial, or real estate-heavy targets) inspect facilities for regulatory compliance and environmental liabilities.

Would you like me to dive deeper into how to structure a due diligence checklist or provide advice on managing external advisors for your specific industry?

In an acquisition, the buyer typically performs due diligence, using a combination of internal teams and external specialists. The goal is to validate the investment thesis, identify risks, confirm valuation assumptions, and determine whether (and on what terms) to complete the deal.

A typical due diligence team includes:

The exact team depends on the size and type of acquisition:

• Small business acquisition: often the buyer, an attorney, CPA, and possibly a financial advisor handle most diligence.
• Middle-market acquisition: commonly involves a corporate development team plus accounting, legal, tax, operational, and industry advisors.
• Private equity acquisition: typically has a deal team, operating partners, outside accounting firms, legal counsel, consultants, and industry experts.

The buyer owns the diligence process, but the seller supports it by providing documents, answering questions, and giving access to management, systems, and facilities.

A common structure is:

1. Buyer signs NDA and receives preliminary information.
2. Buyer submits a letter of intent (LOI).
3. Buyer launches diligence workstreams.
4. Findings affect valuation, deal terms, representations/warranties, indemnities, and whether to close.

If you are building an acquisition program, a practical starting team is usually: deal lead + finance/QoE advisor + M&A attorney + tax advisor + operating subject-matter experts.
