Offering FSA and HSA at Your Business

For merchants, gyms, spas, and studios adding FSA and HSA to what they already sell.

If you sell something your customers could reasonably document as medical, you can let them use FSA, HSA, and HRA money on it. Most businesses in this position do not, usually because they assume it requires payment infrastructure.

It does not. Your checkout stays exactly as it is. Customers pay with any card. Burst handles the letter and files the claim, and their plan administrator pays them back out of their account. Nothing changes in your process at all.

That is the part that matters for recurring billing. Gyms, studios, spas, and subscription brands are the businesses card-based approaches serve worst, because every renewal needs its own substantiation event. Filing after the purchase removes the problem instead of managing it.

These guides cover the operational side: what to tell customers, when to bring it up, how it shows up in your numbers, and why the payment processors cannot solve this for you.
