Step 1: Open the invoice
Open Invoices and tapclick the invoice.


A sent invoice is never changed: it is a record your customer has. To take money off it, you send a credit note, which says which invoice it corrects and why.
An invoice with nothing paid or credited on it can be cancelled instead, and its work can then go on a new invoice.
Open Invoices and tapclick the invoice.


TapClick the three dots at the top of the invoice.


TapClick Make a credit note. It starts as a copy of the invoice.


Under Why it is given, tapclick a reason like A discount we agreed, or write your own. It is printed on the credit note.


Under What it is for, lower each line to what is being taken off, and remove the lines that were right. It can take off no more than is still owed.


TapClick Send by email. Its amount comes off what is owed on the invoice.
Good to know: Nothing paid or credited on the invoice yet? You can cancel it instead: the three dots, then Cancel the invoice, and the reason. Its work can then go on a new invoice.
