I'll help you change the status of the invoice, sandjolney.
Let's open the transaction and delete the payment. This will open it and make it unpaid again. Here's how:
- Open the invoice and click the 1 payment link in the upper-right hand corner of the invoice.
- Click the date of the payment.
- Uncheck the invoice to unlink the payment. You can also click Clear Payment to undo the transaction.
- Click Save and close.
I'll get right back in case you need additional help with your invoices. Thanks!
