If you receive payment for an Invoice that you have previously written off, you can easily undo the write-off under the Invoices & Payments tab in the Accounting section. Undoing the write-off returns the balance back to the Invoice, and increases your Accounts Receivable balance. You can then apply the payment.
To undo the write-off:
- Click on the Invoice No. or click the kebab icon on the right side of an Invoice and select Edit from the drop-down menu to display the invoice edit page, click Actions and select Write-off from the drop-down menu.
- Simply uncheck the "Write-off remaining..." checkbox and click Save.
