If you want to pay for a transaction that exceeds the funds available in your balance, you have a couple of options:
Option 1: Use pooled balances If you have multiple balances that together can cover the transaction, simply use your Fleet card. The transaction will automatically be split across those budgets.
Option 2: Add personal funds If your pooled balances aren't enough, you can add a personal card to cover the difference. See How to Add Additional Funds for step-by-step instructions.
