Do customers need an FSA/HSA card?
How to answer when a customer asks.
No. Customers don’t need to pay with an FSA/HSA card. They buy from you normally, get their letter through Burst, and file for reimbursement from their FSA/HSA.
You don’t change anything at checkout.
What to tell customers
“Pay however you like. Scan this code and Burst gets you the letter that makes it FSA/HSA eligible, then you can get reimbursed from your account.”
If they do have an FSA/HSA card
They can use it. The letter is what makes the purchase eligible, whichever way they pay.
