Hello @abilashraghu
Did you checked How to Create a Refund Item Button? sample?
In SambaPOS refund operation is not connected to a single ticket and a single ticket can contain both refund items and normal sales. That enables you to do:
- You can return items sales from multiple tickets.
- You can change items with another item and pay back or settle the difference.
The linked sample demonstrates how to change a previously sold item with another item and settle the difference. If you don’t give something back and just settle refund items that will automatically generate reverse transaction and decreases cash.
