How is the Partial Refund Product shown in the POS Bill Receipt in Odoo

In a retail store, when a customer wants to return a product, this process is called a
refund. Sometimes, the customer may return only a particular product. The store accepts the customer’s request and processes the refund, returning the money to the customer, typically through
cash payment.

How to Process a Partial Product Refund

Once you have completed the order, click Sales Return. Switch to Head Casher, then scan the bill or search for the bill number in the Search Orders field. Select the product to refund. For example, if multiple products were billed, choose only a few product to refund.

Click the Refund and check the details on the POS cart screen.

When returning to the POS Cart during refund transaction, the refund product quantity, net value, tax amount and total quantity are displayed as negative value to indicate that items are being returned. The quantity and amount fields cannot be modified while the order is in refund mode.

negative value, indicating a refund.
