Overpayment corrections
When working with bank transfers as payment method, it might happen that your customers make double payments or overpayments. In such case, you can use the Overpayment corrections feature to enter payment information about your overpayment refunds made via bank transfer.
Overpayment corrections ensure that any amount paid above the required invoice total is properly adjusted. This process helps maintain accurate financial records, keeping both organizers and participants aligned on the correct balances.
Go to: Finances -> Invoices:

Open the Invoices list -> search/filter the overpaid invoice/s -> click on the overpaid invoice -> a slide window will open -> click on Overpayment corrections:

Fill out the requested information:
- Incoming payment – Select the last paid amount that needs to be fully or partially refunded.
- Reference number – Enter the invoice number.
- Payment ID external (optional) – Enter the refund transaction number (e.g. from Wise).
- Amount – Enter a non‑negative amount. The system will deduct this from the invoice’s total received amount.
