The problem

Every invoice still passes through a person.

Find it. Read it. Code it. Split the lines. Route it to the right entity. Key it into your ledger. The work is slow, reactive, and easy to get wrong, and the only way to keep up is to add people.

Every step, by hand.

The tools hold the data. People hold the logic. Every step depends on them.

02

Categorise it with AI.

Cortena books each invoice the way your business does. Line by line: accounts, cost centres, cost carriers, accruals. It finds the right GL account, well beyond supplier-to-ledger rules.

Your chart of accounts · your logic
03

Route, validate, approve.

Route each invoice to the right entity, apply that entity's own rules, and run approval flows as complex as your org needs. A human stays in the loop: nothing posts until the right people sign off.

Multi-entity rules and approvals
04

Send it to your accounting tool.

Approved invoices go straight into DATEV, Exact, or Twinfield, with payment prepared. In seconds. Your books stay current as invoices arrive.

Booking-ready · audit-traced

Your invoice flow, fully customized, with endless possibilities.

Your flow is orchestrated by the Workflow Builder. It directs the agents, defines the exact path each invoice takes, and connects to the other tools in your stack and files in your drive to optimize every flow. A human stays in the loop, and it bends to fit any organization. Explore the Workflow Builder

Month-end, the series.

We made a little mockumentary about life inside a finance team. Three episodes so far, and every one of them really happened to someone.
