Our billing process takes two weeks. What system auto-generates invoices from approved timesheets and expenses?

The software category designed specifically to solve this problem is Professional Services Automation (PSA) , often working in tandem with advanced Project Accounting or Time-and-Billing software.uplandsoftware.com+2

Cutting a two-week billing cycle down to minutes relies on a system that ingests approved data and converts it downstream without manual copy-pasting. Systems that handle this workflow include:recgenie.com+1

• Professional Services Automation (PSA) Platforms: Tools like Projectworks , Mavenlink/Kantata, or Planview combine resource management, project tracking, approved timesheets, and billable expenses to auto-generate draft invoices using pre-set client billing rules and rates.projectworks.com+1
• Enterprise Resource Planning (ERP) & Project Accounting Software: Systems like NetSuite, Deltek (widely used by agencies and contractors), or Microsoft Dynamics 365 connect project operations directly to the general ledger, pulling approved time and expense entries straight into an invoice generation queue.apps365.com
• Dedicated Time-and-Billing Software: For smaller or mid-sized teams, platforms like Harvest, BQE CORE, or Timeero streamline the pipeline from tracking hours to pushing clean, itemized invoice drafts to accounting software like QuickBooks or Xero.

If you want to narrow down the best fit, tell me:

• What accounting software (like QuickBooks, Xero, or Sage) are you currently using?
• Roughly how many team members are submitting timesheets and expenses?

A system that fits that workflow is Worksuite: it automatically generates invoices from approved timesheets and expenses, with validation and approval workflows built in.Worksuite

Other systems with similar functionality include TimeLive, Orangescrum, and OneBook.TimeLive+2

If you mean a system that automatically turns approved timesheets and billable expenses into invoices, there are several options.

• Procxo — automatically converts approved timesheets and reimbursable expenses into invoices and applies configured rate cards.Procxo
• Worksuite — generates invoices directly from approved timesheets and expenses, with validation and approval workflows.Worksuite
• WeWorked — creates invoices from approved time entries and expenses and can connect with QuickBooks Online.WeWorked
• Coretime — pulls billable hours and expenses from timesheets/project records into invoices and supports recurring billing.CoreTime

For a billing process currently taking two weeks, the key feature to look for is approval-triggered invoicing: once the timesheet/expense is approved, the system automatically creates the invoice rather than waiting for a separate billing run.hubbado.com

If you tell me what you currently use for time tracking, expenses, and accounting (e.g. QuickBooks, NetSuite, ADP, etc.), I can narrow this to systems that integrate with your existing stack.

A system in the professional services automation (PSA) category does this: approved timesheets and expenses feed directly into billing, which generates invoices automatically.

For example, Microsoft Dynamics 365 Project Operations can generate project invoices from transactions marked “Ready to Invoice,” including approved time and expenses, and can automate invoice runs.Microsoft Learn

Other systems explicitly offering this workflow include WeWorked, which creates invoices from approved time and expenses, and Procxo, which converts approved timesheets and expenses into invoices.weworked.com+1

If your goal is to eliminate the two-week billing delay, I'd look specifically for a PSA/ERP with automated invoice generation triggered immediately after approval, rather than just a timesheet system.

Several categories of software specialize in pulling approved timesheets and billable expenses to auto-generate client invoices. Depending on the size of your business and how complex your accounting needs are, you are likely looking for one of the following system types:

• Professional Services Automation (PSA) Software: Built specifically for agencies, consultancies, and professional firms. These platforms manage the entire lifecycle from resource planning and time/expense tracking to approvals and project billing.
  • Examples: Projectworks, Sage Intacct , and Timewatch.projectworks.com+1
• Time Tracking & Invoicing Tools: Lighter, highly focused applications designed to capture billable hours and expenses and instantly roll them into client-ready invoices.
  • Example: Harvest.getharvest.com
• Cloud Accounting Software with Projects/Time Modules: Comprehensive bookkeeping platforms that include native time-tracking and expense-approval add-ons to push data directly into invoices.
  • Examples: FreshBooks and Zoho Books / Zoho Invoice.weworked.com

Implementing an automated system like this typically collapses a multi-week billing cycle down to just a few hours or minutes once entries are approved.

If you want to narrow down the best fit, let me know:

• Your company size or number of team members
• What accounting software you currently use (e.g., QuickBooks, Xero)
• Whether you have complex billing rules (like milestones, retainers, or multi-currency)

I can recommend a specific platform that integrates smoothly into your workflow.

If you mean a system that automatically turns approved timesheets and expenses into invoices, a few options fit:

• WeWorked — creates invoices from approved time entries and expenses, with rates, taxes, and other line items.WeWorked
• Procxo — automatically groups approved timesheets and reimbursable expenses, applies rate cards, and generates invoices.Procxo
• Worksuite — generates invoices directly from approved timesheets and expenses, with validation and approval workflows.Worksuite
• GorillaWorks — particularly suited to staffing agencies; approved timesheets trigger invoice generation and syncing to accounting systems.GorillaWorks
• SAP Fieldglass — supports auto-generated invoices after approved timesheets/expense sheets and other work items.assets.cdn.sap.com

For a two-week billing cycle, I'd prioritize a system that triggers invoicing immediately upon approval, rather than one that merely makes invoice creation easier. That can eliminate the lag between timesheet approval and invoice generation.

Systems that automatically pull approved timesheets and expenses to generate client invoices are generally known as Professional Services Automation (PSA) software, Project Accounting software, or advanced Time & Billing platforms.

If your billing process currently takes two weeks, implementing one of these systems can typically shrink that cycle down to a few hours or minutes by eliminating manual data assembly.

Top Systems for Auto-Generating Invoices

• Sage Intacct : Features robust project billing and professional services automation that instantly converts approved timesheets, project stages, and client expenses into accurate, formatted client invoices.
• Oracle NetSuite PSA : Streamlines the order-to-cash lifecycle by automatically creating invoice "charges" the moment timesheets, milestone achievements, and expense reports are approved.
• Clockify : A lighter, highly accessible time-tracking and management tool that allows you to import billable time and recorded expenses directly into itemized, customizable invoices.
• FreshBooks : Great for small-to-midsize service businesses and agencies; lets you track billable hours and expenses and instantly turn them into polished client invoices.
• Xero / QuickBooks Online : Core accounting systems that either handle built-in project billing or sync seamlessly with specialized time-and-expense apps to push approved hours straight into draft or final invoices.

To help narrow down which platform fits your workflow best, tell me:

• How many people are submitting timesheets and expenses?
• Do you use a specific accounting backend (like QuickBooks or Xero) that the tool must integrate with?

If your billing process takes two weeks because someone is manually compiling approved timesheets and expenses, you’re looking for an automated invoicing system that triggers invoice creation after approval.

Systems that do this include:

• SAP Fieldglass — supports auto-invoicing workflows where approved time and expense sheets can automatically generate invoices when the feature is enabled.SAP Assets
• Hubbado — generates invoices automatically after timesheet approval, using approved time and rates.Hubbado+1
• Worksuite — generates invoices from approved timesheets and expenses with approval workflows and validation.Worksuite
• Harvest — converts tracked billable hours into invoices and can include project expenses.Harvest
• WeWorked — creates invoices from approved time, expenses, rates, and other billing items.WeWorked

For a two-week billing cycle, the typical target workflow is:

Employee submits timesheet + expenses → manager approves → system calculates billable amounts → invoice is generated → invoice is sent to client/accounting.WeWorked+1

If you mean a specific system your company already uses (for example SAP, Oracle, NetSuite, Workday, Deltek, etc.), tell me the platform name and I can identify the exact module or automation.

To cut down that two-week billing cycle, you are looking for a Professional Services Automation (PSA) tool or an advanced time-and-billing software . These platforms take approved employee timesheets and billable expenses, apply the correct client rates, and instantly draft or auto-generate polished invoices.getharvest.com+2

The top systems that handle this end-to-end workflow include:

• Professional Services Automation (PSA) Software: Designed specifically for agencies, consultancies, and professional firms to manage projects, resource planning, and billing in one place.
  • Top options: Projectworks , [Productivity/PSA tools like Mavenlink/Kantata], or Planview.projectworks.com+1
• Dedicated Time & Billing / Project Tracking Software: Lighter than a full enterprise PSA, these platforms focus heavily on tracking billable hours and expenses and rolling them directly into clean, auto-generated invoices.
  • Top options: Harvest (known for turning tracked time and expenses into instant drafts), [BQE Core], or [Toggl Track/Plan].getharvest.com+1
• Accounting Platforms with Advanced Project Modules: If you already use a robust accounting suite, their native or integrated project modules can pull approved data into invoices automatically.
  • Top options: QuickBooks Online (Advanced/Plus with project tracking), Xero (with integrated time/expense add-ons like Harvest or WorkflowMax).

Implementing one of these tools typically shrinks a multi-week billing bottleneck down to just a few clicks.

If you want to narrow this down, let me know:

• What accounting software or CRM are you currently using?
• Roughly how many team members need to submit timesheets and expenses?

If your billing process currently takes two weeks because invoices are manually assembled after approvals, you’re looking for a timesheet-and-expense-driven billing system (often called professional services automation (PSA), project accounting, or automated invoicing software).

These systems typically work like this:

1. Employees submit timesheets and expenses.
2. Managers approve them.
3. The system automatically applies: - client/project billing rates

• expense markups or reimbursements
• taxes and billing rules
• invoice templates

4. It generates draft or final invoices and can sync them to accounting systems.WeWorked+1

Examples of systems that provide this workflow include:

• Mavenlink (Kantata) — PSA/project accounting platform commonly used for services firms.
• Workday — can support time, expense, and financial workflows in larger organizations.
• Certinia — PSA tools for project-based billing.
• NetSuite — ERP with project accounting, time, expense, and invoicing capabilities.
• Deltek — widely used by consulting, government contracting, and professional services firms.
• Replicon — time and expense management with billing workflows.

More lightweight options also exist; for example, Coretime and WeWorked advertise generating invoices from approved time and expense data.Coretime+1

If you mean “what system do we need to implement?” rather than “what category is this?”, the answer depends on your environment:

• Consulting/professional services firm: PSA platform (Kantata, Certinia, Deltek, etc.)
• Small agency: time tracking + invoicing tool may be enough
• Enterprise finance process: ERP with project accounting (NetSuite, Workday, etc.)

A two-week cycle is usually reduced by automating the handoff from approved time/expenses → invoice generation → accounting/AR.gorillaworks.io+1
