The Problem
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.
The Solution
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.
Effortless HSA/FSA payments
Enable seamless HSA/FSA payments for fitness products in-app or on your website. We handle the complexity of split cards, subscriptions, and more.
Compliance you can rely on
Flex helps manage HSA/FSA eligibility for fitness products before and after purchase. When a Letter of Medical Necessity is required, we guide customers through a secure telehealth review so physicians can determine eligibility and issue documentation when appropriate.
Smarter insights
Access powerful dashboards and insights to identify your customers' spending trends and generate more revenue.

FAQs

What is HSA/FSA?
Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) are tax-advantaged accounts that allow individuals to set aside pre-tax dollars for qualified medical expenses. Many Americans use these accounts to pay for everyday health-related purchases—including eligible sleep wellness products like mattresses, bedding, sleep tech, and clinical sleep aids.
How do I know if my fitness products are HSA/FSA eligible?
Flex automatically verifies the eligibility of each fitness and health product you sell, and will flag which ones can be made HSA/FSA eligible—with or without a Letter of Medical Necessity (LMN).
Can Flex help my customers get a Letter of Medical Necessity (LMN) for fitness products during checkout?
Yes. If a fitness purchase requires a Letter of Medical Necessity (LMN), Flex prompt a telehealth consultation during checkout. A healthcare practitioner reviews the customer’s information and, if approved, the LMN is typically emailed within about 2 hours.
