For finance and back-office teams

Stop keying invoices into another system by hand

Automating invoice processing with AI means reading each invoice, extracting the fields your team relies on, checking them against your rules and posting the clean ones to your finance system. Anything uncertain or above your limits waits for a person to approve it.

Step by step

Follow one invoice from the inbox to the ledger

Select a step to see what happens to an invoice there, and where a person on your team stays in charge of the decision.

  • Step
  • Gate: a person decides

  1. Invoices arrive by email, upload or a shared folder, as PDFs or scans. Each one is stored with its source and time of arrival, so nothing goes missing on the way in.

  2. Invoices, credit notes, statements and contracts are told apart first, so each kind gets its own fields, its own rules and the right reviewer.

  3. The system reads the layout and pulls out the fields you agreed, each with a confidence level. Fixed, predictable forms may need no AI at all, and we will say so.

  4. Values are checked against your rules: a known supplier, a matching purchase order, totals that add up and no invoice number seen twice.

  5. Low-confidence fields, failed checks and amounts above your limit wait in a review queue. A person corrects or approves each one, and the decision is recorded.

  6. Approved invoices go to your accounting or ERP system through its API, each with a link back to the original document for audit.

01 Outcomes

What changes for you

  • Less time spent retyping

    Supplier, invoice number, dates, line items, tax and totals arrive as structured fields, so your team checks the exceptions instead of typing every page.

  • Mismatches caught before posting

    Each invoice is checked against your rules, such as a matching purchase order, a known supplier or totals that add up, before anything reaches the ledger.

  • A record behind every entry

    You can see what was read, which rule flagged it and who approved it, so an auditor's question at month end has an answer on file.
