In MicroBiz Cloud, user has ability to make a return to gift card however there are specific steps required to do this.
To do this, you will need to 'sell' a gift card with an amount equal to the value of the items being returned. You do not 'return' the item to a gift card vendor.
Steps:
1) Add item being returned to register screen
2) Select the line item and click the 'Return Item' button from the Action Menu>Items panel
3) Note value of item being returned
4) Press Sell Gift Card button (Action Panel>Transaction>Sell Gift Cards)

5) Scan barcode of any activated card and enter an amount equal to the credit balance of the item being returned.

This should result in no payment or refund due on the register transaction, with the value of the item being returned loaded onto the gift card.
