How to cancel an order or subscription made with HSA/FSA through Flex

Last updated: December 30, 2025

If you need to cancel an order that you made using your HSA or FSA card through Flex, please note that Flex cannot cancel orders directly. Flex processes HSA/FSA transactions for merchant partners but does not have visibility into or control over individual orders.

How to cancel your order

To cancel your order, you will need to contact the merchant's support team directly. Here's how:

  1. Identify the merchant where you made your purchase (this will be mentioned in your Flex receipt email)

  2. Visit the merchant's website and look for their customer support or contact information

  3. Contact them directly with your order details and cancellation request

What information to provide

When contacting the merchant, make sure to include:

  • Your order number (if available)

  • The email address used at checkout

  • Your reason for cancellation

  • Any other details the merchant may require

Why Flex can't cancel orders

Flex partners with merchants to enable HSA/FSA payments at checkout, but the actual order fulfillment, shipping, and cancellation processes are handled entirely by the merchant. This means only the merchant has the ability to modify or cancel your order.

If you have questions specifically about your HSA/FSA transaction or need a receipt for reimbursement purposes, you can contact Flex support at support@withflex.com.
