Not sure why but we signed up for restaurant for the group orders option on square restaurant. However, the biggest problem is that once you start a group order you also loss the ability to use coursing. Sometimes groups what options like entrees first or entree as a main or main as entree at least with coursing this is available but once you select group order it removes that ability to select course type.
Only system I know that doesn't allow for selecting coursing for group bookings. This should be a main factor in the development
