Q. How do I work with Gift Certificates?

Gift Certificates are a great way for your customers to help you build your business. The problem is to bill the purchaser and credit the redeemer without having it mess up your paperwork.
 
Although I didn't put this feature into the DCMS for this purpose, I believe that this is a perfect use for the "Apply and Extra Charge" fields along the bottom of the Recording a Transaction (sale) screen. Enter the amount of the Gift Certificate (i.e. $100) in the number field. Then in the character field to the right of it, type in a description such as "$100 Gift Certificate". The bill will be calculated (if there was anything else she bought) and then $100 added to the bottom (without being taxed).
 
When the receiving customer redeems the Gift Certificate, you can treat it as though she were using cash. Alternately, if the redeemer is one of your customers already, you can use the "Accounts Receivable" option to show a payment of $100 to her account, leaving her a credit, if applicable. It's probably easier to apply it as a cash payment, however.
 
Hope that helps.
