Good day, we have a scenario that we are asking for assistance with:
1. Customer buys and pays for product - sales invoice is raised and payment method is populated as CASH, and sales invoice is posted.
2. Customer comes back and returns a product from the above. He requests that instead of a refund, he would like the incorrect product credited and that we use the credit to fund the correct product he would like to buy.
3. The new product is more expensive and so the credit does not fully cover the cost of the new correct item so he will have to do a top up payment as well for this.
How would we process this transaction?
Thanks
