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

The category of system you are looking for is called Professional Services Automation (PSA) software.

A PSA platform connects project management, resource planning, and time/expense tracking directly with a project billing engine. Once an employee's timesheet and billable expenses are submitted and approved in the system, the platform automatically rolls those line items into a pre-filled draft invoice based on predefined client billing rates and rules.

Common types and examples of software that handle this workflow include:

• Dedicated PSA Software: Tools like BigTime, Projectworks , or PSOhub are specifically built to pull approved hours and expenses straight into project invoices.
• Time Tracking & Invoicing Tools: Lighter platforms like Harvest or Clockify allow you to track time and expenses and convert them into invoices seamlessly.
• Accounting Suites with Project Billing: Heavy-duty accounting and ERP systems (like QuickBooks Online or SAP ) also feature native project-billing modules that ingest approved time and costs.

Implementing a PSA or integrated time-to-invoice workflow typically cuts that multi-week billing cycle down significantly because it eliminates manual data re-entry and cross-referencing spreadsheets.

If you'd like to narrow down a tool for your team, tell me:

• How many people are tracking time and expenses?
• What accounting software (like QuickBooks or Xero) do you currently use?

I can recommend a few platforms that integrate smoothly with your current tech stack.

The system that most directly matches that workflow is Simpata. It supports manager approval of timesheets and expenses, then automatically generates client invoices from the approved entries.

Another close match is Worksuite, which explicitly generates invoices from approved timesheets and expenses and includes validation and batch processing.

If your key requirement is automating a two-week billing cycle, I’d look particularly at a system that supports biweekly billing schedules—SG Connect, for example, advertises weekly, biweekly, and monthly automated billing cycles.

The system designed specifically to handle this workflow is called Professional Services Automation (PSA) software.

A PSA platform connects project management, time and expense tracking, and approval workflows directly to a billing engine. Once a manager or client approves a timesheet or an expense report (with receipt attachments), the system automatically applies the correct client rate cards or fixed-fee rules to generate a draft or final invoice.

Popular categories of systems that achieve this include:

• Dedicated PSA Platforms: Tools like BigTime, PSohub , or Timewatch.
• Time Tracking & Invoicing Tools: Lighter solutions like Harvest or Hubstaff , which handle time/expense logging and convert them straight into invoices.
• Cloud ERPs with Project Accounting: Enterprise systems like NetSuite, Sage Intacct, or SAP that tie resource management and financials into a single unified ledger.

Most of these platforms sync directly with general accounting software (like QuickBooks or Xero) to eliminate manual re-entry and significantly shrink a two-week billing cycle.

If you want to explore fixing your two-week bottleneck, tell me:

• What accounting or project tools are you currently using?
• Are your projects mostly Time-and-Materials (hourly) or Fixed-Fee?

I can suggest whether you need a lightweight time tracker or a full PSA/ERP system to streamline your workflow.

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

A strong match is WeWorked: it explicitly supports approved timesheets + expenses → invoices, with invoice tracking and QuickBooks Online integration.

Other systems with this workflow include:

• Worksuite — automatically generates invoices from approved timesheets and expenses, with validation and approval workflows.
• Harvest — converts billable timesheet hours and expenses into invoices and integrates with accounting platforms.
• Hubbado — particularly suited to contractor/staffing workflows; approval can trigger automatic invoice generation.

For a two-week billing cycle, I’d prioritize a PSA/time-and-expense system with an approval-triggered invoice workflow, rather than an accounting package that requires someone to manually import the approved data.

The system that most directly matches your description is Worksuite: it automatically generates invoices from approved timesheets and expenses, with validation and approval workflows built in.

Another close match is Aldoa, which pulls approved time and expenses into itemized invoices.

If you're referring to a specific system your company already uses, tell me the context (e.g., staffing, consulting, professional services), and I can identify it.

Systems that automatically pull approved timesheets and billable expenses to generate client-ready draft invoices are broadly referred to as Professional Services Automation (PSA) software , or Time-and-Billing platforms.

Implementing these tools typically cuts multi-week billing cycles down to a matter of minutes or days by eliminating manual data re-entry, spreadsheet calculations, and human error.

I can recommend the best system fit to sync seamlessly with your stack.

Systems that auto-generate client-ready invoices directly from approved timesheets and expenses fall broadly into two categories: Professional Services Automation (PSA) software (for comprehensive enterprise and agency workflows) and ** specialized Time-and-Billing / Cloud Accounting tools** (for leaner operations).

Popular, highly-rated software options that handle this exact transition from approved time/expenses to draft invoices include:

• BigTime : A robust BigTime PSA platform tailored for tracking billable hours, managing multi-level manager approvals, applying complex rate cards, and syncing directly with accounting tools like QuickBooks and Sage.
• Harvest : An intuitive tool widely used by agencies and consultancies that lets you track time and snap/attach receipt photos for expenses, then automatically rolls them into clean, client-ready invoices.
• Oracle NetSuite PSA / SuiteProjects : An enterprise-grade cloud solution managing the complete "bid-to-bill" lifecycle, integrating complex project accounting, resource utilization, and automated time/expense billing.
• Accelo : A service operations platform that automates the entire client lifecycle, connecting CRM, project management, and timesheets to seamlessly drive billing.
• Avaza : An all-in-one platform built for professional services that consolidates resource scheduling, expense/time tracking, and automated invoicing under one roof.
• FreshBooks / QuickBooks Online : Popular cloud accounting alternatives that feature integrated time tracking, mobile receipt expense capture, and automated invoice creation for service-based businesses.

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

• Your company size and industry (e.g., small marketing agency, IT consultancy, engineering firm)
• Whether you need a standalone tool or something that syncs with an existing accounting system (like QuickBooks or Xero)

If you mean a system that automatically turns approved timesheets and expenses into client invoices, Worksuite is a strong match. It explicitly supports automatic invoice generation from approved timesheets and expenses, with validation and approval workflows.

Other systems with similar functionality include:

• WeWorked — creates invoices from approved timesheets, billable expenses, rates, taxes, and custom line items.
• Bizinta ERP — automates the flow from approved timesheets/expenses to invoices and can sync with QuickBooks.
• CONREP — pulls approved timesheets into invoices and integrates with QuickBooks Online.

For a two-week billing process, I'd look specifically for an automated “approved time + expense → invoice” workflow, rather than just ordinary accounting software.

A number of professional services automation (PSA), project accounting, and workforce management systems can do this. The common workflow is:

1. Employees submit timesheets and expenses.
2. Managers approve them.
3. The system automatically generates invoices based on billable rates, contracts, and billing rules.
4. Invoices are sent to accounting or directly to clients.

Examples include:

• HubbaDO – Automatically generates invoices when all timesheets for a billing period are approved, applying agreed rates and taxes.
• Worksuite – Generates invoices directly from approved timesheets and expenses with configurable approval workflows.
• WeWorked – Creates invoices from approved time entries and billable expenses, with integrations to accounting systems such as QuickBooks Online.
• ManicTime – Produces invoices from approved timesheet data without manual re-entry.

If your billing process currently takes about two weeks because invoices are prepared manually after approvals, implementing a PSA or time-and-billing platform with automatic invoice generation can significantly shorten that cycle by eliminating manual invoice creation.

If you're asking about a specific product your organization already uses, let me know its name (for example, SAP, NetSuite, Dynamics 365, QuickBooks, Deltek, or another platform), and I can explain how that system handles invoice generation from approved timesheets and expenses.

Systems that automatically pull approved timesheets and billable expenses to create client-ready invoices fall under a few overlapping software categories, depending on the size of your business and how complex your projects are.

• Professional Services Automation (PSA) Software: Designed specifically for project-based businesses (agencies, consultancies, legal, IT services), a PSA tool handles everything from resource scheduling and time/expense tracking to rate-card enforcement and automatic invoice generation. Examples include BigTime, Projectworks, Accelo , and NetSuite PSA.
• Time Tracking & Invoicing Software: For smaller teams, freelancers, or creative agencies that need a lighter footprint than a full enterprise PSA, platforms like Harvest or Clockify let team members log time and expenses, get manager approvals, and roll those items directly into polished invoices with a couple of clicks.
• ERP and Accounting Platforms with Project Modules: If you want your operational data tightly bound to your general ledger without third-party syncing, enterprise resource planning tools like NetSuite or mid-market accounting platforms like QuickBooks Online have built-in billable time and expense features that map approved entries straight into draft invoices.

Implementing a native time-to-invoice pipeline usually slashes a multi-week billing cycle down to just a few hours or minutes because it removes the manual data-reconciliation bottleneck at month-end.

If you'd like to narrow down a specific solution, tell me:

• How many people are submitting timesheets and expenses?
• What accounting software (e.g., QuickBooks, Xero, NetSuite) are you currently using on the backend?
