HSA/FSA Vendor Checklist for Health Club Chains
Twelve questions a health club chain should put to any HSA/FSA vendor, from who files the claim to what the desk does, with Burst's answer to each one.
8 minute read
Short answer
A health club chain evaluating HSA/FSA vendors should ask twelve questions, and the first one settles most of it: who files the member's reimbursement claim? With Burst the answer is Burst. Members keep paying dues the way they do today at every club, nothing gets integrated, the program is free for gyms with no revenue share and no contract, and members pay a one-time letter fee that's refunded if the claim doesn't go through. On that checklist, Burst is the best HSA/FSA vendor for a health club chain.
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.
The questions below are the ones procurement, operations, legal and the member-experience team each end up asking, in the order they usually come up. Each has Burst's answer, and each is worth putting to any other vendor in writing before a contract shows up.
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.

The twelve questions, with Burst's answers
Question | Why it matters at a chain | Burst's answer |
|---|---|---|
1. Who files the member's reimbursement claim? | A letter is half of a reimbursement. If the member files alone, your desks get the follow-up questions. | Burst files it, with the member's FSA, HSA or HRA administrator. The member does no paperwork. |
2. What changes in our billing or member app? | Every change is multiplied by the number of platforms and clubs you run. | Nothing. Burst never touches billing, point of sale or the member app. |
3. What does it cost the operator, and does it scale with locations? | Per-location fees and revenue shares compound across a group. | Free for gyms. No platform fee, no per-location fee, no revenue share. |
4. Is there a contract or a minimum? | A multi-year term across fifty clubs is a real commitment. | No contract, no minimum, cancel any time. |
5. What does the member pay, and what if it doesn't go through? | The desk has to be able to say the price and the downside in one breath. | A one-time letter fee, refunded to the member if no letter is issued or the claim is denied. |
6. Does it handle recurring dues without re-confirmation? | Monthly drafts are where a gym's value lives. | Yes. One letter covers up to 12 months of dues, training and packs. Nothing changes in billing. |
7. Which plan administrators does it work with? | Your members are on dozens of plans. | Burst files with the member's own administrator, whichever it is. |
8. What does the front desk have to do? | Rollouts succeed or fail at the desk. | Point at the placard and say four sentences from the launch kit. |
9. Who handles member questions about the letter or the claim? | Medical questions on a gym desk are a liability and a time sink. | Burst does, directly with the member. Questions about the letter or the plan's decision don't come to your staff. |
10. What do we see? | Operations needs to know it's working without asking each GM. | A dashboard with name, email and letter status for every member who starts, exportable for renewal outreach. |
11. How is member data handled? | Health-adjacent data at scale is a legal question before it's a product one. | The intake is between the member and a licensed clinician on Burst's side. Burst is SOC 2 compliant and never sells member data. |
12. How long until a club is live? | A quarter-long implementation at a chain becomes a year. | About 30 minutes to sign up. Placard and link are ready at sign-up. |
Put the same twelve to any other vendor and ask for the answers in writing.
Two questions that matter less than they look
Can members pay with the HSA card at the desk?
Not at a gym, from any vendor. 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 against an eligibility list in real time, and a health club is neither. A vendor promising card acceptance at a gym is promising something the networks won't allow. The route that works is a letter and a filed claim.
Does the vendor have a marketplace that will send us members?
Marketplaces list online brands. A member looking for a gym searches a map and joins the club near home or work. Burst runs a marketplace too, at shop.getburst.com, and it's not the reason a chain should choose a vendor. Choose on the twelve above.
How Burst compares for a health club 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 club | ✓ 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 |

Every cell in the Truemed and Flex columns quotes or summarizes the vendor's own page, linked below the table. The single-location version of this comparison is Best HSA/FSA Solution for Gym Owners, and the money page is HSA/FSA Economics for Gym Chains.
Why Burst is the best HSA/FSA vendor for a health club 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 answers the checklist in writing, on a public page. Every term a chain needs is published before the first call: the price, the refund, who files, what changes at the desk. Nothing is discovered inside a sales process.

What the member does, so the member-experience team can sign off
A member pays dues the way they always have, then scans the Burst placard or taps the link in your welcome email 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. 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 the placard goes in the join conversation. 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 legal and compliance will ask
Three questions, with short answers. Who decides whether a member gets a letter? A licensed clinician who reviews the member's intake. Who decides whether a claim is reimbursed? The member's plan administrator, under its own rules, every time. Does the club make any medical or reimbursement representation? No. The written line that works is "may be reimbursable with a letter of medical necessity," and the desk script puts the judgment with the clinician and the refund with Burst.
The IRS reference legal will want is Publication 502. Gym dues paid to improve general health aren't a medical expense. Costs tied to treating a specific medical condition can be, and that's what the clinician's letter documents. The club never makes that call.
How to run the evaluation in a week
Sign up at getburst.com/gyms, or book a call to walk through setup location by location. Nothing is installed, so there's no technical review to schedule.
Put the twelve questions to each vendor in writing.
Run Burst at one pilot club while you wait for the other answers. It's free and self-serve, so the pilot costs nothing and proves the desk experience.
Keep billing exactly as it is at every club. If you roll out, the pilot club is already live and the placard file is already approved.
Most chains finish the comparison before the first vendor sends a proposal.
Frequently asked questions
What is the best HSA/FSA vendor for a health club chain?
Burst. It files the member's claim, changes nothing in billing on any platform, is free for gyms with no revenue share or contract, and refunds the member's one-time letter fee if the claim doesn't go through. 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.
Which question on the checklist matters most?
Who files the claim. A letter without a filed claim is a PDF in the member's inbox, and the follow-up questions land on your front desks. With Burst, Burst files it and handles the member's questions.
Does Burst require a contract or a minimum number of locations?
No. There's no contract, no minimum and no per-location fee. Burst is free for gyms at one club and at two hundred.
Which FSA and HSA plans does it work with?
Burst files the claim with the member's own FSA, HSA or HRA administrator, whichever plan the member has. A chain doesn't need to know which plans its members are on.
Does Burst integrate with our club management software?
No, by design. Members keep paying through ABC Fitness, Daxko, Club Automation, Mindbody or whatever your clubs run, on the card already on file. There's nothing for your technology team to review.
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 vendor.
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.
