Till, invoices and VAT
Taking payment, paying in instalments, correcting an invoice, SumUp terminal, end-of-day closing: quick answers.
I made a mistake on an invoice
It can no longer be edited: the law forbids it. You correct it with a credit note, which produces a numbered document. See Refund a customer properly.
The customer pays in instalments
Choose 2, 3 or 4 instalments in the payment window. The invoice is issued for its full amount and stays “To be paid”; it is the last instalment collected that switches it to “Paid”. Tracking is in Invoices & Quotes, Paiements échelonnés (Instalment payments) tab. The customer receives their reminder automatically on the due date.
Why does my invoice stay “waiting for the terminal”?
Because your SumUp terminal is connected and the payment has not come through yet. It usually does within a few seconds, at the latest at the next check (every ten minutes).
How do I close the till at the end of the day?
Checkout → Closing (Z report): the expected total per payment method, your count, and the difference. A refunded credit note leaves the drawer; a credit note granted doesn’t touch it, since the customer leaves with a right, not with money.
