Upgrade a gym · Access control and gym software compatibility
The questions to ask before any system goes on your door
Access control is where hardware meets software, and it is where gym owners most often get locked in without noticing. The door reader is cheap; the decade of being unable to change billing providers because the door only talks to one system is not.
This guide names no vendors as recommendations. It gives you the question set that makes any vendor conversation productive, the lock-in warning signs, and the data rights you should insist on in writing. Every claim here is a question for you to ask, because the honest answers are contract-specific.
What we could NOT verify
Vendor integration lists, pricing triggers and failure behaviour change contract to contract and release to release — nothing on this page asserts what any named system does today. That is exactly why every item below is phrased as a question for the vendor to answer in writing.
How the pieces connect (and why it matters)
A typical stack has four parts: access control (the door), billing (the money), CRM (the pipeline) and member comms (the messages). The upgrade trap is buying them one at a time, each on its own contract, each holding a copy of your member list, none obliged to talk to the others. Two years later, changing any one part means renegotiating all four.
Before adding or replacing any part, map what you have: which system is the source of truth for the member record, and which systems hold copies? If you cannot answer that in one sentence, that is the first thing to fix, and it costs nothing.
The vendor question set (the embedded tool)
Send these in writing before any demo. Written answers become part of your negotiation record; verbal ones evaporate. Score two vendors side by side in the fill-in columns — nothing you type is stored or sent anywhere.
Integration
| Question | Vendor A | Vendor B |
|---|---|---|
| 1. Which billing and membership systems does your access hardware integrate with today, natively, without a third-party middleware fee? List them. | ||
| 2. If my billing provider changes, does the door keep working? What exactly breaks, and what does re-integration cost? | ||
| 3. Is there a documented API, and is it included in my price or a paid tier? |
Lock-in
| Question | Vendor A | Vendor B |
|---|---|---|
| 4. What is the minimum term, and what does exit cost before term? | ||
| 5. Is the hardware usable with any other software if we part ways, or is it bricked without your service? | ||
| 6. Do you charge per member, per door, per site, or a flat fee, and what triggers a price change? |
Data rights
| Question | Vendor A | Vendor B |
|---|---|---|
| 7. Can I export my full member list, payment history and access logs myself, at any time, in a standard format (CSV or equivalent), without asking support and without a fee? Show me where the export button is. | ||
| 8. On termination, how long do I have to retrieve my data, and when is it deleted? | ||
| 9. Where is my member data stored, and who else can access it? For Australian gyms, member data sits under the Privacy Act; ask the vendor to confirm their compliance position in writing rather than taking a badge on a website at face value. |
Operations
| Question | Vendor A | Vendor B |
|---|---|---|
| 10. What happens at the door when your service or the internet is down? Fail-open, fail-closed, or cached credentials? Each is a different risk; make them say which. | ||
| 11. What is your after-hours support arrangement, given a 24/7 gym has its emergencies at 2am? |
Lock-in warning signs
Treat any of these as a flashing light, not a dealbreaker on its own but a reason to slow down:
- Proprietary hardware that only works with one software subscription. The door becomes a hostage.
- “Free” hardware with a long software term. You are financing the hardware through the term; price the exit.
- No self-service data export. If getting your own member list requires a support ticket, you do not control your member list.
- Per-member pricing with no cap. Your success raises their invoice; model it at twice your current members.
- Integration promised on the roadmap. Roadmaps are not contracts. If the integration you need does not exist today, price the plan as if it never will.
- A reseller between you and the vendor. Ask who you actually contract with and who answers question 10.
What “compatible” should mean in your contract
Aim to leave every negotiation with three things in writing: the integration list (question 1), the self-service export right (question 7), and the door's failure behaviour (question 10). If a vendor will not put those three in writing, that is your answer, and it cost you one email to learn it.

If this guide surfaced a bigger question — whether your current stack is the constraint on your growth objective rather than the door itself — the Gym Upgrade Scorecard places software gaps alongside your facility and equipment picture so you can see which pain is actually the expensive one.
