The swipe
Time, place, gallons, and the unit or card that was used.
EFS
An EFS swipe still has to meet a truck.
Updated 2026-10-07
EFS is a common over-the-road fuel card. The statement knows the gallons. It does not know whether your tractor was at that pump. I read the EFS file next to GPS. You keep the card.
What an EFS row can tell you
A typical EFS transaction export includes date and time, merchant, location, product, gallons, unit price, total, card or unit number, and sometimes a driver name. Those labels vary by report. I start from the export you can already download, or a read-only login you create.
EFS sits in the WEX family of fleet products. I do not need you to migrate cards. I need a week of purchases and the GPS you already pay for.
What it cannot tell you alone
It cannot tell you the assigned tractor was at the island. It cannot tell a typo from a stolen fill. It cannot tell a tank sensor to behave. That is the join.
If part of the fleet is still on Relay or Comdata after an acquisition, say so. Mixed cards are normal. I match each brand instead of forcing one file.
Checklist for an EFS audit week
- Can you export transactions with time, merchant, gallons, and unit?
- Is the unit on the card the unit in the TMS?
- Which GPS is on those tractors?
- Who administers the EFS cards and who can close one?
What I look for
What I need from EFS
The truck
A GPS ping for that window.
Your key
Read-only. You can pull it.
Short answers
Before you book.
No. The audit reads EFS. It does not replace it.
If you also run WEX cards, I read those in the same pass. They are related products, not the same file until you say they are.
Next step
Let's match one week of EFS swipes.
15 minutes. Tell me who administers the cards and who can see GPS.
