PEX Credit Expense PEX now offers a Credit Expense Card that can be used to reserve and rent vehicles just like any standard credit card- no work arounds needed! Cardholders with the Credit Expense Card can present it at the time of reservation and at pickup without restriction. Cardholders should first verify policies over the phone with the location where the vehicle will be retrieved before a reservation is made. Most merchants share information online, however, those policies may not be location specific. 💡 Want to learn more about our credit product? Contact our support team at adminsupport@pexcard.com. Using a PEX Prepaid Expense Card for Car Rentals If your organization uses PEX Prepaid Expense Cards, please note the following: Most car rental companies will not allow you to reserve a rental car using a prepaid debit card; however, they will allow you to pay for the rental upon return of the vehicle. Recommended process:
  1. Before making a reservation, cardholders should verify the rental location’s prepaid card policy directly by phone. Policies listed online may not reflect location-specific rules.
  2. Use a personal or corporate credit card to reserve and pick up the vehicle.
  3. Upon return, ask the merchant to run the final transaction on your PEX Prepaid Card for final payment.
Limiting Car Rentals with the PEX Card Business Administrators can restrict a cardholder’s ability to rent a car by updating the Spend Rules for that cardholder.
  1. Navigate to the Category table on the Spend Rules tab for the cardholder.
  2. Uncheck the boxes under the “Travel & Transportation” column.
  3. The card will then decline at all merchants within that category, including car rental companies, airlines, railroads, taxis, buses, and gas stations.
Note: Even if Travel & Transportation is disabled for a cardholder, an Administrator can still grant access to specific rental car companies by creating a Custom Merchant Category containing the desired vendors and assigning it to that cardholder.
Note:Changes to Spend Rules are real-time, so be sure to inform the cardholder of spend rule updates.For information on how to set or update spend rules, see How to Set Spend Rules on a Card and Managing Custom Merchant Categories.
