Procountor automation · runs daily

Verify and approve Procountor purchase invoices

Supplier invoices pile up in invoice circulation, and each verifier or approver has to open them one by one before anything can be paid.

Cotlet does it in your own Procountor account with list_purchase_invoices, get_purchase_invoice, verify_purchase_invoice and approve_purchase_invoice, called by your AI agent, an n8n workflow or a script.

Can Procountor do this on its own?

Procountor has circulation inside the app: widgets, notification emails, and a Verification of multiple invoices option in Receipt search (checked 14 Oct 2026). It cannot apply your own rule, such as supplier plus amount, and the docs we could open do not list approval calls in the REST API.

How you do it in Procountor today

  1. Turn on approval circulation once under Management > Company info > Invoice circulation management.
  2. For a manually entered invoice click Send to circulation; electronic invoices notify the first verifier automatically.
  3. Find waiting invoices in the Invoices waiting for verification widget or in Receipt search with the search type Invoices to approve.
  4. Open the Verification view and click Verify or Approve, which adds a stamp with your name, date, time and an optional comment; use Exception when you cannot approve.
  5. Approved invoices are then paid in the Payment view, so one forgotten approval holds up a payment run.

How to verify and approve Procountor purchase invoices

Prompt

List the Procountor purchase invoices waiting for my verification or approval. Approve the ones from suppliers I named in the list below that match the amounts, and leave the rest with a one-line reason.
  1. 01

    Read what waits for you

    list_purchase_invoices filters to invoices waiting for your verification or approval, so the agent only touches invoices where you are the named verifier or approver.

  2. 02

    Open each invoice

    get_purchase_invoice returns supplier, amount, dates and the stamps already on the invoice. The agent compares them with your list and skips anything that does not match.

  3. 03

    Check duplicates

    Procountor warns when another invoice matches on dates, invoice numbers, bank reference, sender or total sum. The agent reports a warning and leaves that invoice for you.

  4. 04

    Verify first, approve second

    verify_purchase_invoice runs where you are a verifier. approve_purchase_invoice runs only after verification if verifiers are specified, because Procountor does not allow approval before that.

  5. 05

    Leave the rest with a reason

    Anything unclear stays in circulation with a one-line note, so you can use Exception options in the app yourself.

What you get back

Example data

Waiting for you: 9
Approved 6 (supplier on your list, amount matches)
Verified only 1 (approval is the next person)
Left for you 2:
- Office Supplies Oy: duplicate warning, same bank reference
- Studio Kivi: amount differs from the order
Payment view: 6 invoices ready to pay

Other ways to ask

  • Every morning, approve invoices under a limit I set from suppliers on my allow list.
  • Only verify, never approve, and send me the list of what the approver still has to do.
  • Show me everything with a duplicate warning and do not approve anything.

What Procountor allows, and what to know first

  • Procountor purchase invoice statuses are Received, Unfinished, Verified, Approved and Payment denied.
  • If verifiers are specified, an invoice cannot be approved before it is verified; verification can run in order or in parallel, depending on the company settings.
  • Only approved purchase invoices count as business transactions and can be paid in the Payment view.
  • The duplicate warning does not appear in Verification of multiple invoices or in the mobile app, so the agent checks it per invoice.
  • Payment denied is reversed by clicking Approve.

verify_purchase_invoice and approve_purchase_invoice ask for your OK by default. To run it daily without you, switch confirmation off for those tools in your dashboard.
