How to choose gym management software (a guide for Chile)

Most guides on choosing gym software list features: memberships, reports, integrations. That's useful for building a checklist, but it's not where the money gets lost.

The decisions that turn out expensive are different ones: whether recurring payments actually work in Chile, whether you can pull your data out the day you want to switch, and whether the system lets you comply with the personal data law — because a gym handles health information, and that carries legal consequences starting December 2026.

1. Recurring payments in CLP: the point that decides everything

This is the criterion to start with, because it rules out entire platforms.

A gym lives off the monthly fee. If billing isn't automatic, someone chases payments every month, and delinquency becomes a full-time job. A system that's excellent at everything else but can't charge automatically in Chilean pesos doesn't solve the main problem.

What to ask, word for word:

• Which gateways does it integrate with in Chile? Webpay/Transbank, Mercado Pago, Flow, Khipu are the ones that matter. An international platform that only integrates with Stripe or PayPal can leave out the payment method your members actually use.
• Does it support a subscription with recurring charges, or only one-off billing? These aren't the same. One-off billing requires the member to actively pay every month.
• What happens when a charge fails? Expired card, insufficient funds, issuer decline. A serious system retries, notifies the member and keeps the case visible; a bad one lets it quietly go unpaid.
• Does it issue an electronic receipt or invoice, or integrate with something that does? If not, accounting ends up doing by hand the work the system was supposed to save.
• What's the total fee? The gateway's plus the software's. Some platforms charge an extra percentage on top of what's processed, and at volume that weighs more than the subscription itself.

2. Health data: what changes with Ley 21.719

A gym almost never sees itself as a company that handles sensitive data, and it almost always does.

A record with weight, body fat percentage, blood pressure, prior injuries, a medical certificate or a health declaration is sensitive personal data under Ley 21.719, in force from December 1, 2026, which brings an agency with sanctioning powers and fines in UTM. Sensitive data requires explicit consent and stricter security measures than a contact detail does.

That turns several technical questions into legal ones:

• Where is the data stored? If it's outside Chile, you have an international transfer, and the law requires a legal basis for that.
• How is consent recorded? You need to be able to prove the member accepted, for what, and when. An unlogged checkbox doesn't hold up as evidence.
• Can a member actually be deleted? The right to erasure is enforceable. If the system only lets you "deactivate," you can't comply.
• Is there role-based access control? The front-desk person doesn't need to see anyone's medical record. If every user sees everything, the design is already a problem.
• Does the provider sign a data processing agreement? As the data processor, the software answers for its part — but you remain the one accountable to your members.

We wrote separately about what Ley 21.719 means and what to do before December, with the detail on the law itself.

3. Leaving the system: ask before you get in

The question that saves the most money later is the one asked least: how do I get my data out if I want to leave?

A gym with two years of history has data that's worth something: members, attendance, payments, active subscriptions. If the system doesn't export that in a usable format, switching costs so much that in practice you can't — and next year's price gets set by a provider who knows it.

What to check concretely:

• Export of members, memberships, payments and attendance history to CSV or Excel, without having to ask support for it.
• An API, even if you don't use it today. It's the difference between being able to integrate something later and not being able to.
• What happens to recurring subscriptions: billing mandates usually live with the gateway, and migrating them without asking every member for their card again depends on how it was set up from the start. This question is boring and it's the most expensive one that gets discovered too late.

4. Access control: where the hardware lives

If you want a turnstile, fingerprint reader, QR or card access, hardware integration is what varies the most between platforms — and what shows up least on the marketing pages.

• What devices does it support, by brand and model?
• What happens if the internet goes down? An access control system that lets nobody in while offline is a serious operational problem at peak hour.
• Does check-in validate membership status at that moment, or does it only log the entry?

If you're not putting in hardware for now, it's still worth knowing whether you could. It's the kind of decision that shows up a year later.

5. What actually gets measured day to day

The usual features, but with the question that makes each one useful:

Area	The question that matters
Class bookings	Does it handle capacity, waitlists and a late-cancellation policy?
Plans	Can you create a new plan yourself, or do you have to ask the provider?
Reports	Does it show retention and delinquency, or only the month's revenue?
Member app	Does it exist, and does it work from a phone without installing anything?
Multi-location	Can members use more than one branch, and are reports split by location?
Support	In what language, what hours, and what time zone?
Migration	Who loads your current data, and is it included?

On reports, one is worth insisting on: retention. This month's revenue tells you how you did; the churn rate tells you how you're going to do. A system that doesn't show you how many members stopped showing up before they stopped paying is hiding the indicator that would have warned you first.

6. The total cost, not the list price

Add this up before comparing:

• Monthly subscription, at the tier you'll be at in a year, not today's.
• Per-transaction fee from the software, if any, plus the gateway's.
• Implementation and data migration.
• Team training.
• Hardware, if applicable.
• Modules billed separately — this usually happens with the member app and access control.

How to evaluate it in a week

1. Write down your three critical processes — monthly billing, signing up a new member, booking a class — and ask to see them in a demo, with your cases, not the vendor's.
2. Ask for a trial with real data from twenty members. Problems show up with real data, not sample data.
3. Ask the four questions nobody asks: how do I export everything, where is the data stored, what happens when a charge fails, and what happens to billing mandates if I leave.
4. Talk to a current customer of the provider, similar in size to you. If they can't connect you with any, that's already information.

ApexFit

We built ApexFit to solve this list from the local side: CLP charges with Webpay and Mercado Pago, class bookings and scheduling, live check-in and access control, and a dashboard with revenue, attendance and delinquency.

Said plainly: if you already have a system that charges automatically, that lets you export your data, and that lets you comply with Ley 21.719, switching probably isn't worth it. This guide works just as well for evaluating what you already have.

And if you're deciding right now, let's talk — with or without us in the mix, the questions above are the ones worth asking.
