Unlock revenue by making your fitness products HSA/FSA eligible
Boost checkout conversion by 30% and AOV by 50% with the only HSA/FSA payments solution built for leading fitness brands
Trusted by top fitness brands




Most consumers don’t realize fitness is healthcare — and many classes and equipment purchases qualify for HSA/FSA spending. With $150B+ in pre-tax health funds available, fitness brands are leaving money on the table. And even when customers know, confusing payment flows and reimbursement hurdles create friction and drive drop-off.
With Flex integrated payments, customers can use their HSA/FSA cards directly at checkout — and instantly obtain a Letter of Medical Necessity when required. No paperwork, no reimbursement, and far less drop-off.
