How to switch gym management software without losing a billing cycle

Export everything before you cancel anything

Your access ends when your subscription does. Most platforms let you export your own data while you're a customer, and what happens after that varies: Mindbody says you lose access the day the site is deactivated, and Zen Planner's terms let them delete the data once the billing cycle ends. So the very first move, before you've picked a new system or even finished shopping, is to pull your data out and put it somewhere you control.

• Your member list: names, emails, phone numbers, birthdays, status, membership name, and the next payment date for each person. That last column is the one people forget and the one this whole guide hangs on.
• Your attendance or check-in history, as far back as you care about. You won't get this again.
• Anything with a signature on it: waivers, consent forms, medical notes.
• A screenshot of your billing setup. Plan names, prices, billing intervals, who is on what.

Plan to run both systems for three or four weeks

This is the part owners resist, because it means paying twice for a month. Pay twice for a month. A second subscription costs you somewhere between $30 and $200. One missed billing cycle at a 90-member academy puts five figures of dues in limbo, and getting it back means a week of awkward emails asking people to pay you again. Some of them won't.

The overlap exists so that every member's charge date passes at least once while you still have both systems in front of you. Once someone has been billed successfully in the new system, they're done and you never think about them again. Work through the roster in charge-date order and the whole thing drains itself.

Cancel the old subscription when the last person on the list has paid through the new one, and not before. A finished import doesn't count. The money has to have moved.

Saved cards don't travel in a spreadsheet

This one surprises people: your members' saved card numbers can't be exported to a spreadsheet, by anyone. Card data lives with the payment processor, under PCI rules that exist specifically to stop it being emailed around as a CSV, and any vendor who offered to hand you one in a file would be telling you something alarming about how they store it.

That leaves two routes that actually work.

1. Re-collect as you go. Enroll each member in their new plan as their renewal date comes up and take the card then, at the desk, the next time they're in for class. Spread across a month at a 90-member gym, that's three people a day. This is the path almost everyone takes and it's less painful than it sounds, because you're talking to them on the day their payment was due anyway.
2. Copy them processor to processor. If the old platform billed through a Stripe account you own (most platforms that say "connect your Stripe account" work this way) and the new one runs on Stripe too, you can copy customers and their saved cards between the two accounts yourself, from the Stripe Dashboard. The old account clicks Copy customers, the new one clicks Authorize and Accept, and a roster-sized copy finishes in a couple of hours. The card numbers never leave Stripe. If the old platform ran its own processor instead, Stripe's migrations team will take an encrypted export from any PCI Level 1 processor, but that goes through both companies' support desks, so start it the day you decide to switch. Either way, ask the new platform first whether it can attach a copied card to the right member, otherwise the cards sit in the account unused. Worth the effort at 200 members, rarely below 50.

Import in this order, or the history won't attach

Attendance records point at two things: a person and a class. Neither exists in a brand new account, so importing history first produces a pile of rows attached to nobody. Members first, then your programs and schedule, then history.

1. Members. Upload the CSV and map the columns. Check the preview for anyone whose status or birthday didn't parse before you commit it.
2. Programs and classes. Build the schedule you actually teach this term, not the one from two years ago that you've been meaning to clean up.
3. Attendance history. Upload it and map each old session name to one of your new classes. Anyone who doesn't match by email or name shows up in the preview, so you fix it before anything is written.
4. Ranks and belts. Set these in bulk from the roster once everyone is in. They rarely survive a CSV cleanly and it's faster to do it as one pass.
5. Billing plans. Create them, then enroll members as their charge dates arrive.

A good importer lets you upload the same file twice without creating duplicates, which means you can run it, look at what happened, fix the spreadsheet, and run it again. Check that before you trust one with your roster.

What actually moves, and what you rebuild

If you teach kids, check the consent gate

Under-13 members are the one category where an import can quietly put you offside. In the US, COPPA covers the personal information an online service collects from children under 13, and it wants verifiable consent from a parent or guardian before that happens. Importing a birthday doesn't import that consent.

What you want is a system that holds imported kids behind the same consent gate as ones you add by hand: on the roster for you, not visible on the kiosk or any public sign-up surface, until a guardian has confirmed. Then link the guardian and send the request. If your new platform doesn't distinguish a child record from an adult one at all, that's worth knowing before you move 60 kids into it.

A four-week timeline that works

None of that is technically hard. The hard part is the last row, because by week three the new system looks finished and the old invoice is annoying. Wait for the money anyway.
