Not a problem. Subsync is only $0.25 a class! We monitor any changes to class schedules you make in Mindbody, so if you reduce classes or cancel classes your monthly cost goes down. If you add more classes, our billing will add on the additional classes. Subsync is priced per class scheduled in MindBody and includes unlimited teachers, substitutions and messages. For example, if you have 21 classes a week at $0.25 a class, the cost is just $5.25 a week!
