A Trainerize alternative built for the coach, not the client count.

The growth tax, in actual dollars.

The whole pitch of per-active-client pricing is that it's cheap when you're small. And it is — a coach with two clients pays almost nothing. The catch is the slope. As your roster grows, the platform takes a bigger cut of your time's worth, and you feel it most at exactly the moment you're busiest: month nine, roster full, every new client a little more expensive to host than the last.

VitalCoach flips the slope flat. Once you're on Pro at $79/mo, client number 6 and client number 60 cost the same in software: nothing extra. A full roster is where flat pricing wins hardest, because that's where per-client pricing is most expensive. If you're still filling your first few seats, Solo at $19/mo for 5 clients (with AI generators included) is the honest comparison — and Free covers your very first client with no card at all.

The billing chore nobody quotes you.

Trainerize lets you take client payments by connecting your own Stripe. That's genuinely useful — but it means the processor fee and the admin are still yours. On a $200/mo client, Stripe's 2.9% + 30¢ is $6.10/mo — about $73/year per client — and you're the one invoicing, retrying the failed card in month four, chasing the lapsed payment, and reconciling Stripe against your bank at tax time. None of that shows up on the sticker price.

VitalCoach's billing engine bundles all of it. We're the merchant of record: we collect from your client, keep a flat 5%, and pay you 95% on the 1st of each month — bank deposit, PayPal, Wise, or paper check over $50. The failed-card retry, the chargeback risk, and the PCI compliance are our problem, not yours. So the real comparison isn't "2.9% vs 5%." It's "2.9% plus your own admin vs an all-in 5% that does the admin for you." Run your own roster through the pricing-guide math and pick the cheaper all-in number.

And there's a kicker on Pro: once 5% of your monthly client billings reaches $79, your Pro subscription is waived that month. At roughly $1,580/mo in client billings, the platform pays for itself. Prefer to keep your own Stripe? The 5% engine is opt-in — you can run VitalCoach for the coaching tools alone and bill clients however you like.

Where Trainerize is still the right call.

We'd rather you stay put than switch and churn back in a month, so here's the honest other side. Trainerize is the established incumbent — part of ABC Fitness — with years of feature depth, a polished native client app your members may already know and trust, and a broad integration ecosystem. If your clients live in that app and love it, if you depend on a specific integration, or if you simply want the most battle-tested platform on the market, that maturity is real and switching costs you some of it. VitalCoach is the newer, leaner option; it wins on flat pricing and bundled billing, not on breadth of integrations. Switch for the reason that actually hurts, not for the novelty.

How to move without breaking your roster.

There's no one-click import — you re-create each client and re-attach their programming, and clients sign in to the new platform. So don't migrate everyone on a random Tuesday. The clean playbook:

• Start free. Open a VitalCoach account and rebuild one program template you reuse often. Cost: $0.
• Run one client end-to-end for two weeks. Log sessions, send a check-in, export a PDF — make sure the daily workflow fits your hands.
• Migrate at a billing boundary. Move the rest of the roster at the start of a billing cycle so client billing dates stay clean and nobody gets double-charged.
• Switch on billing when you pass 5 clients. Turn on the 5% engine once you're on Pro and let the fee-waiver math start working for you.

Two weeks of overlap is cheap insurance. The goal isn't to leave Trainerize fast — it's to leave it once, cleanly, and not look back.
