How do I reverse a "receive payment" made by mistake? Clicked on "receive payment" by mistake, now shows invoice as paid.

Thanks for reaching out to us, zee1. 

I'll be glad to help you in reversing the payment you've accidentally added.

You can go to the Invoices tab to locate and open the paid invoice. Then, delete the linked payment so that the invoice status will go back to unpaid or open. Here's how to do it:

1. Select Sales from the sidebar menu.
2. Head to the Invoices tab.
3. Find and click the invoice to expand the view.
4. Select Edit Invoice.
5. Click the Payment made link below the Payment Status section.
6. Select the payment, then go to More.
7. Choose Delete, then hit Yes to confirm the changes.

In addition, I've included an article that will help you track all the invoices that are due on a particular day or date range: Report of outstanding invoices.

Should you have any additional questions or concerns, feel free to post them here and I'll take care of them. Have a pleasant day ahead.
