Why ISVs should prioritize HSA/FSA integration in their healthcare platforms
ISVs can help healthcare merchants grow by supporting HSA and FSA payments, unlocking new revenue and expanding into digital-first health services.
The U.S. healthcare landscape is undergoing rapid digital transformation, with independent software vendors (ISVs) playing a pivotal role. As more patients utilize virtual care, wellness apps, and online health services, the demand for smooth and secure payment experiences increases. Meanwhile, consumer-directed healthcare spending is rising, with Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) being instrumental.
By the end of 2026, the HSA market is projected to reach 44 million accounts, totaling an estimated $168 billion in assets. Although many of these funds are allocated for clinical care, an increasing share is being spent on everyday health products and digital-first services, including mental health subscriptions and fitness programs.

The expanding scope of HSA and FSA spending
Consumer-directed healthcare spending has expanded beyond just clinical procedures. Although many HSA and FSA funds are used for medical treatments, dental work, and eye care, about one-third now goes toward everyday healthcare products like over-the-counter medications, wellness items, and personal care essentials.
This shift is speeding up as the IRS adds more eligible categories, with mental health services, fitness programs, and even doctor-prescribed wellness subscriptions increasingly being covered. As a result, more health-related businesses are entering the HSA/FSA market.
For ISVs, this expansion opens the door to new verticals. Platforms that support HSA and FSA payments can serve not only traditional healthcare providers but also rapidly growing direct-to-consumer (D2C) brands in the wellness space. By enabling these transactions, ISVs position themselves to capture a larger share of the digital health market.
Why HSA and FSA integration is a strategic advantage for ISVs
As healthcare spending moves online, ISVs have a unique chance to assist merchants in meeting changing consumer expectations. Enabling HSA and FSA payment acceptance is more than just a technical upgrade; it's a strategic decision that can drive long-term growth.
Many healthcare businesses are actively looking for platforms that support compliant and flexible payment options. By providing built-in HSA and FSA capabilities, ISVs can address a crucial challenge for their clients while enhancing the value of their own solutions.
This feature also promotes loyalty. Merchants are more likely to stay with platforms that help them access billions of dollars in consumer-directed healthcare funds. And for potential customers, HSA and FSA support can be a key differentiator when choosing software providers.
Finally, integration opens the door to new verticals. With eligible spending expanding into wellness, fitness, and virtual care, ISVs can serve a broader range of merchants, including fast-growing direct-to-consumer brands in the health space.
Common barriers to HSA and FSA payment acceptance
Despite the growing demand for HSA and FSA payment options, many healthcare businesses and ISVs still face difficulties in implementing them successfully. Several key challenges continue to impede the industry's progress.
- Eligibility confusion: Merchants often struggle to understand which products and services meet IRS guidelines. As eligibility rules change, staying compliant becomes more complicated without automated tools.
- Checkout friction: HSA and FSA debit cards require specific merchant category codes (MCCs) to process correctly. If a business uses the incorrect MCC, transactions may be declined, resulting in abandoned purchases and lost revenue.
- Limited payment infrastructure: Many payment processors lack built-in support for HSA and FSA rules, especially for remote transactions like online orders, subscriptions, and telehealth appointments. This leaves merchants without a seamless way to accept these payments.
- Technical resource constraints: Smaller healthcare merchants and lean ISV teams often lack the time and expertise to integrate HSA and FSA capabilities. Without simple, out-of-the-box solutions, many businesses are forced to delay or abandon implementation.
