Refunds
There are two types of refunds. Referenced refund where a specific card payment is being refunded or a standalone refund where a negative balance in the POS is refunded to a card.
Not all payment service providers support both of these. See more information for each payment service provider here.
Referenced refunds
When returning a transaction, that has a card payment, by receipt ID.
Run the return transaction operation and enter a receipt id or select a transaction from the daily journal.
You can select to return all the items or just a part of the items.
Then you press the Authorize card operation to refund the negative balance to card through the PSP.
Return receipts are printed from the PSP and the LS One receipt also.
If the transaction had multiple card payments you will see a dialog of all card payments done on this transaction and you can select which card payment you want to refund.
If your payment service provider does not support referenced refunds the LS One POS will fall back on standalone refunds.
Then it is advised to uncheck the Supports referenced refunds setting in the terminal setup.
Standalone refunds
Standalone refunds are done when the POS has a negative amount because items have been returned and the Authorize card operation is used to finalize the transaction. No prior card information is used.
Not all PSPs support standalone refunds, the POS will give a message to the user if this is the case. See more information for each payment service provider here.
Note that the Card payment type can be limited to not allow negative payment amounts.
