What Is HSA & FSA Payment Acceptance?
HSA/FSA acceptance lets your customers pay with the debit card tied to their Health Savings or Flexible Spending Account. Funds settle to your bank like any card transaction, but the buyer uses pre-tax money. For qualifying products (often supplements with a Letter of Medical Necessity, OTC items, and select wellness products), this is a powerful conversion lever.
Most generic processors like Stripe, Square, and PayPal will not configure HSA/FSA acceptance for supplement or peptide merchants, and many high-risk processors lack the IIAS (Inventory Information Approval System) integration required at checkout. We support both.
Why Peptide and Supplement Stores Add HSA/FSA Acceptance
Adding HSA/FSA payments solves 3 problems at once: higher average order value, lower chargeback exposure, and access to a buyer pool that competitors cannot serve.
- Pre-tax purchasing power increases basket size by 20 to 35 percent
- HSA/FSA debit cards have lower fraud and dispute rates than consumer credit cards
- Eligible-item tagging and Letter of Medical Necessity workflows handled in-platform
- Same MID, same dashboard, same settlement as your other card processing
What Counts as an HSA/FSA Eligible Product
IRS Publication 502 governs what qualifies. Common eligible categories for our merchants include OTC medications, select supplements with a Letter of Medical Necessity (LMN), wellness devices, and many compounded products. We help you map your catalog to eligible SKUs during onboarding so HSA/FSA cards approve at checkout instead of declining.
