No. To sell gift cards, there is no need to use the booking feature in Just turn ON the gift card feature!

It is also possible to use our booking system AND the gift card feature at the same time. For that, you need to also turn ON the booking feature by going to Settings > Booking > 

Please note that if you are not using the booking feature, please keep it OFF.
