WEX for developers

Your WEX benefits debit card makes it easy to spend your funds on eligible expenses.

Where does it work?
Our card works at a variety of merchants. Specifically, you can use it anywhere with an Inventory Information Approval System (IIAS) or at merchants that meet the IRS’ 90 percent rule (where 90% of gross sales meet eligibility requirements).

How does it work?
If used at an IIAS merchant, simply swipe your card and it will automatically approve anything that’s an eligible expense. If used elsewhere, you may need to upload supporting documentation (depending on your benefits plan).

What if additional documentation is required?
You can view the status of your claims and upload documentation easily with our benefits mobile app or through your online account.
