Mindbody or Seshman? Which fits a solo PT

You look at your client book. Fifteen regulars. A few who come once a week, some twice, a couple who pay as they go. You train them in a rented corner of a commercial gym, at a park on Wednesdays, sometimes at the client’s place. You run the business from your phone.

Someone suggests Mindbody.

Mindbody is a serious piece of software. It runs studios. It runs spas. It runs franchises with twelve staff and four rooms. Its Starter plan is listed from £89 a month per location, and the tiers above it don’t publish a price at all — you talk to sales, depending on which problem you’re unlucky enough to have.

If you run a studio with staff, that is the right tool for the job. If you are one PT with a client book, it is built for a different business.

What Mindbody is actually for

Mindbody exists to run a multi-staff service business. Timetabled classes. Multiple rooms. A front desk. Payroll. A POS terminal. Email marketing to a membership list. Waitlists for the 6am spin class. Staff permissions so your instructors can’t accidentally issue refunds.

Every one of those features is there for a real reason — a studio somewhere needs it. None of those reasons are yours.

What a solo trainer actually does

You take bookings over WhatsApp. You issue a package of ten sessions when a new client signs up, then deduct one each time you train them. You chase a payment once a month. You answer “how many sessions do I have left?” in text messages more often than you’d like to admit.

You don’t have reception staff. You don’t operate at multiple locations in the sense Mindbody means — a park and a gym aren’t locations in a room-booking sense. They’re where you happen to be on Tuesday.

The job is small in scope and huge in repetition. You do it twenty times a week.

The mismatch costs more than the price

The monthly fee isn’t actually the main problem. The main problem is that you’ll spend weeks learning a tool built around a business model you don’t have. You’ll set up staff accounts you don’t need. You’ll wire up a POS you don’t own. You’ll configure room booking and multi-instructor timetabling for a studio you don’t run. The interface will always be pointing you at features designed for someone else.

Meanwhile the one thing you wanted — “Sarah has three sessions left, she owes £120, remind me to check in before Thursday” — is buried behind screens that assume you’re also running a yoga studio.

What a one-person tool actually looks like

A tool for solo trainers has a narrow shape:

• A client list with session balances visible in one glance.
• A way to issue a package, complete sessions one at a time, and see when someone’s running low.
• If you run the odd small group or bootcamp, a simple register and per-head payment, set up in a minute.
• Payment tracking that doesn’t force you to take payment one way — some clients pay by bank transfer, some cash, some tap a card in the app.
• A client-facing view so your clients can check their own balance without texting you.
• Setup in minutes, not weeks, on a phone, between sessions.

That’s the shape. Scheduling and a calendar you can trust matter — ideally one that syncs to the calendar already on your phone. A Saturday bootcamp fits the same shape: you take the register and get everyone paid, and the tool should make that a minute’s work.

When the tool is scoped to a one-person workflow, the price collapses with it. Tens of pounds a month instead of hundreds. Setup takes an evening instead of a fortnight. The client app is free for the client rather than an upsell, because the whole point is that you and your client see the same numbers.

What to check if you’re shopping

The tests are blunt:

• Does the pricing page have a tier for one person, or does it start at “up to five staff”?
• Is “session package” a first-class concept or bolted on to memberships?
• If you run a small group now and then, can it take a register without making you build a class timetable?
• Does it work properly on a phone, or is the mobile app an afterthought to a web dashboard?
• Do your clients have to pay for their side?
• How long does it take to onboard? Solo-operator tools should be usable in under an hour.

If the answers run the wrong way, the tool is built for a different business. Keep looking.

Seshman is built specifically for this shape of trainer — you can see what that means in the features.
