Hello,
Recording the proper payments towards your invoices is an essential task that will keep your books up-to-date. If you've accidentally hit "Received Payment" on your invoice, you can reverse that by simply deleting the associated payment. I'll explain how to do that.
1. Click the Sales tab on the left navigation menu.
2. Select Invoices from the upper menu.
3. Click the invoice you accidentally recorded payment for.
4. Click the tab that says "1 payment made" to open the corresponding payment.
5. Click More.
6. Select Delete.
That's all there is to it. If you have any other questions, please don't hesitate to reach out to our tech support team.
Cheers.
