Credit Card Refunds - "cannot exceed sales cap" error

Q: When we are trying to process a credit card Refund, sometimes an error comes up saying "Cannot exceed sales cap."  What does that mean?

A: When doing a Refund transaction it will usually reference the last credit card Payment (instead of sending new credit card information), to refund it to the same card that was used for the last Payment.  The error indicates that it's not allowing you to refund an amount larger than that original Payment.  You can get around it by clicking "Redo swipe" and then manually entering the card information (or swiping again), so it doesn't reference the previous payment and limit the amount.  Note that if you get an error like "missing reference" when doing this, you'll need to contact your merchant services provider and have them enable your account for "refunds without reference".
