Automate your company’s invoicing

Invoicing should be fast, accurate, and connected — not a bottleneck. With Koho PSA, you can automate the entire billing process, from contracts and work-time entries to recurring services and intercompany charges.

Fewer manual steps → Fewer errors → Faster cash flow.

Invoicing solution built for accounting firms

Koho PSA brings invoicing into the same system where you already manage all the other business operations. You can generate invoices directly from time entries, signed contracts, or even client requests submitted through tickets. Hours, services, products, and expenses are pulled in automatically.

Billing rules are applied consistently across clients, whether you’re invoicing by the hour, by fixed-fee packages, or by service level. However you price your work, Koho PSA supports it and keeps it running smoothly.

Speed up billing and reduce manual work

Creating invoices with Koho PSA is significantly faster compared to similar systems, as everything is connected. Invoices are generated from the same data you’re already tracking in Koho PSA:

  • Billable time (from approved time entries)

  • Accepted tenders and signed contracts

  • Recurring services and product items

  • Ticket-based or ad hoc work

You can also add sales items manually on the invoice when needed.

Faster cash flow and fewer mistakes

Koho PSA helps you invoice accurately and on time, every time:

  • Avoid missed hours or forgotten service lines

  • Apply billing rules automatically based on the client or contract

  • Minimize rework with cleaner, more consistent invoices

Once the invoice is ready, just send it straight to your financial management system. As a result you spend less time on admin, make fewer corrections, and enjoy a smoother revenue cycle.

Work orders keep recurring billing under control

Koho PSA’s work orders take your workflow to the next level. They help you stay on top of recurring billable work and its subtasks, so nothing is left undone or unbilled. They also improve accuracy by keeping work, time tracking, and invoicing linked in the same view. All this gives you more time for productive work.

Automatic intercompany billing

For companies with multiple offices, Koho PSA simplifies internal invoicing by automatically generating internal charges between teams. Work completed across locations is consolidated into a single client invoice. No manual transfers or internal admin required.

For example, if a client managed by your Turku office receives support from Helsinki, Koho PSA handles the internal billing logic and creates one clean invoice for the customer. Everything stays accurate and connected, without extra overhead.
