Business Box Start free

Online booking for Pilates studios

The reformer is the constraint. Three machines means three people, however big the room is, and every booking decision follows from that one fact.

In short

Business Box books one party per slot, so it fits private and duet reformer sessions rather than group classes. Fifty minutes with a ten-minute buffer after, paid online, 24-hour refund window.

Capacity is equipment, not floor space#

A studio that takes bookings by message will eventually accept a seventh person for six machines, and someone will be told at the door. It only has to happen once to lose a client.

The second issue is the ten minutes nobody counts: springs reset, carriage wiped, straps adjusted for the next person’s height. Book classes on the hour with a fifty-minute session and that ten minutes comes out of the class.

The setup to start from#

The reformer is the constraint, not the room: three machines means three people, whatever the floor space says.

Worth asking on the booking form: Have you used a reformer before? · Any injuries or recent surgery? · Pregnant?

Worth knowing before you start

Business Box books one party per time slot, so several customers cannot sign up for the same class individually — the first booking takes the session. It fits private sessions, trials and one-to-one teaching today. See what that means for group classes. One booking, one slot

One booking takes the slot#

Worth knowing before anything else: Business Box takes one booking per time slot, so six clients cannot each book the 10:00 reformer class. The first booking takes it.

That makes it a good fit for private and duet sessions, which are much of the revenue in a reformer studio anyway, and a poor one for group classes today. One booking, one slot

Mat and reformer are different products#

Different capacity, different price, different people. Two event types, each with its own cap and its own hours, on the same booking page. A client sees two clear options rather than a calendar they have to interpret.

The beginner session that protects the class#

A compulsory introductory one-to-one keeps general classes moving. Make it its own event type, priced, with a longer duration, and say in the description that it comes before any group class. Ask about injuries and pregnancy on the form — booking form questions.

Common questions

Can six clients book the same reformer class?

No — one booking takes the slot, so the first person to book it takes the class. Business Box suits private and duet sessions rather than group classes today.

Can I require a private intro session before group classes?

Not as an automatic rule, but in practice yes: make the group class invite-only and send an invite link once someone has done the intro, or state the requirement in the class description and check the booking list.

How do I get time between classes to reset the machines?

Set Buffer after to ten or fifteen minutes on the event type. It is invisible to clients and simply cannot be booked into.

Set this up in about ten minutes
