Flex lets customers use their HSA/FSA funds on health wearables and smart devices. Devices that are always eligible go straight through, and the rest get a Letter of Medical Necessity inside your checkout.
Trusted by leading smart health brands
Some health devices, like blood pressure monitors, are always HSA/FSA eligible. Others need a Letter of Medical Necessity first. Flex handles both inside your checkout.
Get StartedRight next to card and wallet payments.
Items that are always eligible go straight through. Items that need a Letter of Medical Necessity get a short online consultation.
You're paid out like any other card payment.
Wearables and smart health devices are considered purchases. Letting customers pay with pre-tax health dollars gives them another way to fit one into their budget.
Flex checks every order, runs the qualification and provider consultation when one is needed, and handles the documentation. Your team never has to judge who qualifies.
