How to issue a credit note in RMS

Depending on how your sku is structured - you could issue a Work Order (taking full deposit - or override the deposit amount you might already have required on your system). As your GC sku is likely not able to be placed on a WO, your generic/dummy sku might not be set as NI, allowing it to be placed on a WO. OR, if you are expecting the cards soon, and you can float an inv off qty, I would sell something that you do not traditionally sell, overwrite the description on the POS (this can be done, printing to the receipt, journaling the text, etc w/out actually changing any properties of the line item going forward) to read Gift Card or similar - then when the customer comes back for a swap - simply recall and exchange the trx (placing inv back OH and relieving the GC).

Make sense?
