Our memberships are based around account credit so they can be used for any service. They also get one free add-on monthly. For example: a gold membership cost $85 and the client gets $100 in store credit plus one free $15 add-on. BLVD is assigning the value of the voucher as $85 and changes the price of the add-on to $85 when redeemed. Making the voucher amount editable would improve the client experience (receipts are confusing) and accounting on the backend.
