Amend my invoice’s payment status
On your SumUp profile, click "Invoices" in the left hand panel.
Select "Invoices" and choose the relevant invoice.
Click "Add payment" and enter the payment amount, the date of the payment and any relevant notes.
Once you submit the info, your invoice’s status will automatically update. It’s possible to enter partial payments for invoices on the SumUp profile, but not the app.
Cancel an invoice
Finalised invoices cannot be deleted for legal reasons. But you can create credit notes to cancel all or part of an invoice.
