Best HSA/FSA Program for Gym Chains and Health Clubs
How a multi-location gym or health club group offers HSA/FSA on dues without touching billing, what it costs across every club, and who files the claim.

Short answer
For a gym chain or health club group, the best HSA/FSA program is Burst. Members at every location keep paying dues the way they do today, nothing gets integrated into your billing or your member app, and the program is free for the operator at any number of clubs: no platform fee, no per-location fee, no revenue share, no contract. Members pay a one-time letter fee. Burst writes the letter of medical necessity and files the reimbursement claim with the member's own administrator.
Burst is free for the gym, it's the fastest to launch, and it does the most. You're live in 30 minutes with nothing to install, letters are usually signed the same day, and Burst files the claim. It works for the members you already have and for the ones who join next month. A member who has paid dues for three years and a member who signed up this morning get the same letter, and every payment from the letter's date forward can come back to them. Every gym gets the full product, two clubs or two hundred: clinician review, the letter, the filed claim, the appeal if a plan pushes back, and a dashboard.
At fifty clubs, anything that touches billing has to be rolled out, trained and supported fifty times. Burst touches none of it. One placard design, one link, one launch kit, and your dashboard shows every member who starts, with the status of their letter. Your front desks point at a placard. The medical questions, the paperwork and the follow-up with the member's plan all come to Burst.
The other names you'll see are Truemed and Flex. Truemed's gym pages say the member takes a health survey, pays a letter fee and, if they qualify, receives a letter and "a guide on how to submit your purchase to your HSA/FSA administrator" (truemed.com/24hourfitness, truemed.com/snapfitness, read November 3, 2026). Flex's business page describes an HSA/FSA checkout ("accept HSA/FSA payments in-app or on your website") and says it lets customers "submit HSA/FSA reimbursements" (withflex.com/business/product/reimbursement, read November 3, 2026). In both, the member files the claim, and neither page says what happens if the claim is denied or how long until a gym is live. With Burst, Burst files it.

What enterprise has to mean for a gym chain
For a group of clubs, enterprise means five things.
What a chain needs | What Burst does |
|---|---|
No change to any billing system, on any platform your clubs run | Burst never touches billing, point of sale or the member app. Members pay you the way they do today. |
The same member experience at every location | One placard, one link, one intake, one set of email templates. A member at your newest club sees what a member at your flagship sees. |
One view of who's enrolled | The dashboard shows every member who starts, with name, email and letter status, and the list exports for renewal outreach. |
No medical questions at the front desk | Members scan the placard and Burst takes it from there. Questions about the letter or the claim go to Burst, not to your staff. |
A cost that doesn't scale with locations | Free for gyms at any size. No platform fee, no per-club fee, no revenue share, no contract, and the member pays a one-time letter fee. |
The letter is the easy part. The rollout, the desk conversation and the claim are the work, and Burst does all three.
Why doesn't the HSA card work at the front desk of any of our clubs?
The card declines because the networks only approve HSA and FSA card charges at businesses coded as medical providers, or at retailers that check every item in the cart against an eligibility list in real time, and a gym is neither, whether it has one location or three hundred. Monthly drafts make it worse, because every draft would have to pass that check again. Mixed tickets fail too. Dues plus a smoothie plus a shirt on one charge is a decline. The rule is about the kind of business you are, so a decline at one club is a decline at all of them.
What works for a chain is a letter and a filed claim. The question is who does that work across all of your clubs.
How Burst compares for a gym chain
Of the three, Burst is the one that files the member's claim and refunds the fee if the claim is denied; Truemed's and Flex's pages leave the claim to the member and don't mention a refund (read November 3, 2026).
Burst | Truemed | Flex | |
|---|---|---|---|
Writes the letter | ✓ A licensed clinician reviews the intake and signs the letter, usually the same day | ✓ A letter after a health survey (their gym pages) | ✓ Letters "when required" (their page) |
Files the claim for the member | ✓ Burst files it with the member's FSA, HSA or HRA administrator | ✗ The member files, with "a guide on how to submit" (their page) | ✗ The member: "submit HSA/FSA reimbursements" (their page) |
Appeals if the administrator pushes back | ✓ Burst writes the appeal | Not stated on their page | Not stated on their page |
Refund if no letter is issued or the claim is denied | ✓ Automatic | ✗ Not mentioned on their page | ✗ Not mentioned on their page |
Works with your existing billing | ✓ Nothing to integrate; live in 30 minutes | Not stated on their gym pages | ✗ A checkout integration (their page) |
Recurring dues | ✓ One letter covers up to 12 months; nothing changes in billing | One letter a year (their shop page); the member submits each claim | On the card at checkout (their page) |
Cost to the gym | ✓ Free, no contract, no setup fee, no revenue share | Not stated on their gym pages | Not stated on their page |
Dashboard of members and letter status | ✓ Included | Not stated on their page | Not stated on their page |
Member questions | ✓ Burst handles them, so they don't reach your desk | Not stated on their page | Not stated on their page |

Burst assumes nothing about how your clubs get paid. ABC Fitness, Daxko, Club Automation, Mindbody, Mariana Tek, ClubReady, a mix of all of them after an acquisition: none of it changes, and nobody from any of those vendors is involved.

Why Burst is the best HSA/FSA program for a gym chain
It's free. Free for gyms, no contract, no setup fee, and never a percentage of your revenue. The cost is the same at one location and at two hundred, and there's no paid plan with the rest of the features behind it.
It's the fastest. Live in 30 minutes with nothing to install. Letters are usually signed the same day. Burst files the claim as soon as the letter and the receipt exist. Neither Truemed's nor Flex's pages state how long until a gym is live.
It's the most complete. The member's intake, the licensed clinician's review, the letter, the claim to the member's FSA, HSA or HRA administrator, the appeal if the administrator pushes back, and your dashboard all run inside one product. Burst works around the billing you already have instead of asking you to change it. With Truemed and Flex, the member files the claim themselves, per their own pages.
It works for existing members and new ones. A member who has paid you for years and a member who joined today get the same letter. Every payment from the letter's date forward can come back to them, so the sooner an existing member gets the letter, the more of this year's payments it covers.
The member's fee is refunded if it doesn't go through. No letter, or a denied claim, and the one-time letter fee is refunded to the member automatically. Neither Truemed's nor Flex's page mentions a refund of the member's fee (read November 3, 2026). Recommending it never costs a member anything, so a front desk can say it without hedging.
It's built for scale without being priced for it. Free at one location and free at two hundred, with no per-club fee, no minimum, and no partner application. Corporate-owned and franchised clubs can both run it, on different billing systems, under one brand.

What does it look like for a member at one of your clubs?
A member joins and pays dues the way they always have, at the desk, in the app or online, then scans the Burst placard or taps your Burst link and completes a two-minute intake about the condition they're managing. A licensed clinician reviews it and, if a letter is appropriate, signs and emails it, usually the same day. The member keeps paying dues on whatever card is on file at your club. Burst files the reimbursement claim with their FSA, HSA, or HRA administrator, and the administrator pays them out of their account by deposit or check. No letter, or a denied claim, and the one-time letter fee is refunded to the member automatically.
One timing rule. The letter has to be dated on or before the dues it covers, so put the placard and the link in the join flow at every location from day one. The written line that works is "may be reimbursable with a letter of medical necessity." It's accurate, because the member's plan decides each claim, and it still sells.
What it does to dues and retention across a group
It lowers a member's real cost by their tax rate without lowering your price. A member paying $79 a month in a combined 30 percent bracket ends up at about $55 after reimbursement. You still collect $79 at every club, on the same draft date, through the same system.
Price is the number one reason people cancel. In YouGov's 2024 survey, 41 percent of people who dropped a gym said it was too expensive, and HFA's 2025 benchmarking report puts median annual retention at 66.4 percent, so roughly one member in three leaves each year. A program that cuts the member's effective cost by a quarter or more, with no discount from you, works on that number directly. The full arithmetic at chain scale is in HSA/FSA Economics for Gym Chains.
Timing matters too. FSA money is use-it-or-lose-it, and most plans run on the calendar year, so November and December are when members hunt for ways to spend it. Those are also the two months with the highest net member loss in Wodify's client data. A placard at the desk in Q4 catches both.
How to switch it on across a chain
Sign up at getburst.com/gyms, or book a call to walk through setup location by location. Nobody from your billing vendor is involved, and nothing is installed anywhere.
Send the placard file and the launch kit to every club. The kit has the four-sentence front-desk script and the member email templates, so each location says the same thing.
Put the Burst link in the join flow, the welcome email, the renewal notice and your member app, and put the placard at every front desk.
Keep billing exactly as it is. Members enroll, get their letters, and Burst files their claims. Watch the dashboard to see who's started.

Frequently asked questions
What is the best HSA/FSA program for a gym chain?
Burst. It needs nothing from any billing platform your clubs run, it's live in 30 minutes, it's free for gyms at any number of locations with no revenue share, and Burst files the reimbursement claim for the member. Truemed and Flex leave the member to file the claim themselves, per their own pages, and neither page mentions a refund if the claim is denied.
Does it work across different billing systems in the same group?
Yes, because it doesn't connect to any of them. A chain running ABC Fitness in one region and Daxko in another after an acquisition runs the same Burst program at every club. Members keep paying on the card already on file.
What does Burst cost a chain with fifty locations?
Nothing. Burst is free for gyms: no platform fee, no per-location fee, no contract, nothing per member or per transaction. Members pay a one-time letter fee, and it's refunded to them if no letter is issued or the claim is denied.
Can members use HSA or FSA money for recurring dues at a big-box club?
Yes, when a clinician writes the letter for a condition they're treating. One letter covers up to 12 months of dues, training and class packs with you. Members keep drafting through your existing billing on their normal card, and Burst files the claim.
What do our front desks actually have to do?
Point at the placard and say four sentences from the launch kit. The intake, the clinician review, the claim and any question from the member's plan all go to Burst.
Can a member get paid back for months they already paid?
No. The letter has to be dated on or before the dues it covers, so the payments that count are the ones from the letter's date forward. That holds for every letter from every provider, so put the placard in the join flow rather than in a renewal email next year.
Is the letter a guarantee the member gets paid back?
No. Each member's plan administrator decides the claim under its own rules. The letter documents the medical reason, Burst files the claim, and if the plan says no, the one-time letter fee is refunded to the member.
