Welcome to Flex! The easiest way to start accepting HSA/FSA Payments


Flex makes it easy to accept HSA/FSA payments for wellness related services and products that are not on the predefined IRS list.

We provide a prebuilt, hosted checkout page or UI building blocks to integrate HSA/FSA payments directly into your existing payments flow.

What are HSA/FSA's

HSAs (Health Savings Account) and FSAs (Flexible Savings Accounts) are accounts that allow you to set aside pre-tax money to be spent on health related purchases.
