No, SugarWOD does not do gym operations (payments, scheduling, accounting, etc). Our experience is that when one company tries to do "all in one", usually the results are somewhat mediocre in each area. That's why we've partnered with Zen Planner to connect our systems! Our integration with Zen Planner is in the works.
SugarWOD also integrates today with Push Press and even without an integration, it complements most gym operations systems well though. Virtually all of our customers are using something like Zen Planner, PushPress or Mindbody to do their back-end work.
You can find more information on why SugarWOD doesn't "do it all" on our blog post here.
