coupon value voucher#1371

It vould be nice to have a coupon type like a voucher,
in our SPA we often sell 100.- , 200.- vouchers.
When a client book a for exemple 75.- appointment the value should be deducted from the voucher and the voucher have a new value and can be reused later

I need also to use voucher as only payement method (need to hide the price and make this field mandatory)

YES PLEASE! Just realised that the coupons do not have “stored value” after use. I really need this - key feature to my booking system.

So a customer gets a coupon worht 1000,- and uses it to pay a booking for 600,- The coupon should now store the value of 400,- for further purchases in the future.

Can this be implemented?
