Overview

Together, Flex and SHOPLINE are making it possible for SHOPLINE’s 600,000+ merchants to accept HSA and FSA payments directly at checkout, unlocking a new channel to reach U.S. consumers who want to use their pre-tax health dollars to make purchases online.

SHOPLINE empowers merchants to sell across the globe through a unified platform that combines online stores, offline retail, social commerce, and cross-border solutions. As SHOPLINE expands its solutions for the health and wellness sector, enabling merchants to reach new customer segments across the U.S. is a key priority. Flex is proud to partner with SHOPLINE as its strategic HSA/FSA payment provider, helping brands unlock access to millions of consumers using pre-tax health dollars.

“At SHOPLINE, our goal is to empower every merchant to scale globally with the same sophistication as the world’s largest brands,” said Christopher Yang, Co President of SHOPLINE. “Partnering with Flex gives our merchants a new way to serve U.S. consumers, expanding their reach into a massive and fast-growing health and wellness market, while maintaining the simpicity and compliance SHOPLINE is known for.”

The Flex and SHOPLINE integration enables merchants to accept compliant, tax-advantaged payments in just a few clicks—no custom development or manual verification required.

“SHOPLINE has built an incredible global platform that helps merchants grow across borders,” said Sam O’Keefe, CEO & Co-Founder of Flex. “Together, we’re making it simple for global brands to offer compliant HSA/FSA payments and capture demand that was previously out of reach.”

How it Works

After signing up for a Flex account, SHOPLINE merchants simply install the Flex app in both the SHOPLINE and Flex dashboards. Flex automatically verifies product eligibility, processes compliant transactions, and handles Letters of Medical Necessity when needed, while SHOPLINE manages storefront, checkout, and fulfillment.
