Write off invoice
From Protemos Wiki
Write off invoice page: https://cloud.protemos.com/client-invoice/write-off?id=XXXX (replace XXXX with a valid number)
On this page, you can write-off the invoice.
Write off is the unpaid part of the invoice that you are not expecting to be paid in the future,
so you may want to mark the invoice as fully paid by adding a write off:
E.g. you invoiced the client for 1000 EUR but got 990 EUR because of the bank charges,
and for some reason, you are not going to ask the client to pay 10 EUR difference.
