Take payments with Grow, Cardcom or another provider

Updated 2026-10-17

The Ledger issues the documents. A payment provider such as Grow, Cardcom, PayPlus or Bit collects the money. The two work side by side.

First: turn off the provider's documents

Most providers issue their own receipt or invoice for every payment. Turn that off in the provider's settings, or ask their support to. Otherwise every payment gets two documents with two different numbers, and your books stop matching the bank.

Way 1: by hand

1. In the Ledger, add the provider's payment link as a payment method: Settings > Payment methods, type Card or Other, paste the link.
2. Send the client a payment request with that method ticked.
3. When the provider tells you the money arrived, open the payment request and click Record payment. Pick Card, and paste the provider's transaction number as the reference.
4. The Ledger issues the receipt. Send it to the client.

Two minutes per payment. Fits a business with a few payments a week.

Way 2: automatic, for technical users

The Ledger has an MCP endpoint, a door for other software, at its address followed by /mcp. It takes JSON-RPC calls (tools/call) with the header Authorization: Bearer and your MCP token. The tools include list_clients, create_draft, finalize_document and record_payment.

An automation tool such as Make, Zapier or n8n connects the provider to it:

1. In the provider, turn on the webhook for successful payments and point it at a new scenario.
2. In the scenario, find the client with list_clients, using the payer's name or email.
3. Record the payment against the open payment request with record_payment and confirm: true. The scenario needs the payment request's document id. Keep a small table of payment link to document id, filled when you send each request.
4. The Ledger issues the receipt.

This takes an afternoon to set up and test. Start with one small payment. For the MCP token, see Connect Claude or another app.
