Reformer studios have a fixed equipment footprint — 6, 8, 10 beds in a room. Capacity is not just “how many people fit in a class” but “which bed does each person get.” Clients learn the room: the front-window bed has more space, the back-by-the-mirror bed is quieter. Generic class-booking software treats spots as interchangeable. Reformer software treats each spot as named.
Pilates studios sell three different commercial structures in parallel: class packs (5-pack, 10-pack, intro offer), open memberships (unlimited monthly), and term-based progressions (six-to-twelve-week courses, often paid in full upfront). Generic booking tools handle one of those well and make you stitch the rest together by hand. Pilates software needs all three to work out of the box, on the same calendar, paid for the same way.
Privates and duets are 1-2 client appointments running alongside group classes on the same equipment. The schedule needs to show them on the same calendar, with the same instructor view, and handle the different deposit and cancellation rules each service type often has.
