There are 2 ways of adding sales return

First way:

Edit existing invoices for the sales by going to edit the invoice and remove the product or reduce the quantity of the product. And save it. The system will automatically add the returned quantity back to stock. This is a simple & recommended way of doing it.

Second Way:

• NPPOS.com will adjust these values in the Profit & Loss report.
• Regarding payment, users have to add a transaction for receiving payment from the customer and then paying them back. This way all the transactions are recorded.
