In some cases, you might determine that a client isn’t going to pay you for an invoice, and you will have to write it off. This means the invoice amount will be removed from your unpaid accounts and appear as lost income.
All written-off invoices will appear in the bad debt section on your Profit & loss report.
To write off an invoice, find the invoice on the Invoices page, select Write-off invoice from the invoice menu, and confirm.
Partially paid invoice
In a similar way, you can also write off the outstanding amount on an invoice for which you have received a partial payment.
First find the invoice on the Invoices page. Then from the invoice menu select Write-off outstanding amount.
Once you confirm the write-off, the invoice status will be updated to paid, and you can find it under the paid tab.
