The add-ons are great IF you never have to change anything on the appt! If you need to change say the first service, for example single process, the gloss add-on will be removed! Then you following service is moved up, so you have to retype the gloss, and then re-add the last service ( and you better remember if it was a blow out or a haircut, cause it's gone, and we all know we are always juggling several things at the front desk!)
So please unlink the add-ons to another service, so we can easily make changes. Thanks
