Flex

Flex is the growth platform powering the next generation of health and wellness commerce. By unlocking access to more than $150B in pre-tax HSA and FSA spending, Flex helps brands turn a payment method into a customer acquisition engine that can drive higher conversion, larger baskets, and entirely new audiences.

Flex enables merchants to accept HSA/FSA payments directly at checkout or offer reimbursement for eligible purchases made out of pocket. From fitness and recovery to sleep, supplements, skincare, and more, Flex helps customers understand what is eligible and use their HSA/FSA funds across a growing range of health and wellness products and services.

Built to integrate with Stripe and leading commerce platforms, Flex manages the infrastructure behind the HSA/FSA experience, including product eligibility, payments, split payments, reimbursements, and Letter of Medical Necessity (LMN) consultations when required. Qualifying customers can complete a simple chat-based consultation, with eligibility determinations and LMNs provided by licensed medical providers directly at checkout when required.

Flex works with thousands of health and wellness brands and has powered more than 2 million HSA/FSA orders. For merchants, HSA/FSA creates more than another way to pay. Customers can use pre-tax dollars on eligible purchases, giving them around 30% more purchasing power depending on their individual tax circumstances. Flex partners have seen up to a 30% lift in conversion and 50% higher AOV with HSA/FSA, while giving customers a more seamless way to use benefits they already have.

Flex is built for businesses of all sizes, with flexible integrations across leading commerce platforms and APIs for custom technology stacks. From eligibility and compliance to payments and reimbursement, Flex provides the infrastructure merchants need to quickly launch and scale HSA/FSA as a meaningful growth channel.
