What a credit note does
A credit note issues money back to a customer — either as a cash refund through the gateway, or as account credit that drains against future invoices (before any card). Every credit note posts to the double-entry ledger and tracks its own balance.Full lifecycle and filters: Credit Notes.
Prerequisites
- An API key for the API call below, or dashboard access.
- An existing customer with an invoice to credit.
- For cash refunds: a connected payment gateway — the refund settles through it.
Step 1: Create the credit note

Credit Notes — each note's amount, remaining balance, and status
Step 2: Choose refund vs. account credit
- Cash refund — the amount is returned via the gateway; settlement completes when the gateway webhook confirms it (mandate payments are refundable too).
- Account credit — the amount becomes spendable balance applied to future invoices automatically, before any card.
Step 3: Track the balance
A credit note carries a running balance as it’s applied or refunded, and can be voided while unused. The customer’s overall credit balance reflects all active adjustment credit notes.Verify your setup

The credit note exists with a balance
It appears under the customer/invoice with its amount and remaining balance.
2
A refund settles / credit applies
A cash refund flips to settled on the gateway webhook; account credit reduces
the next invoice’s amount due.

The ledger balances
The credit note’s legs post to the ledger — the invariant harness keeps it
balanced.
