What stands out
- Fees are published, which many fuel cards don’t do. One truck on Unlimited pays $3 a month after the $35 setup.
- Works anywhere Visa is accepted, so you’re not stuck when a partner stop isn’t on your route.
- Flex gives a credit line without a personal guarantee, and both cards report to Experian to help build business credit.
- IFTA reporting and accounting export are included.
What to watch
- The 42¢ average only applies at AtoB’s partner stations; off-network fills get no stated discount.
- Flex costs $15 a month even for one card, and needs 3 months of revenue proof.
- AtoB’s own page lists two different late-fee figures (see below). Read your card agreement.
- Its stated average (42¢) is lower than TCS (49¢) and OTR (50¢), which are network cards.
AtoB Unlimited vs AtoB Flex
| AtoB Unlimited | AtoB Flex | |
|---|---|---|
| Type | Prepaid Visa card. Load funds and autofill when low | Credit card. Charge now, pay at the end of the billing period |
| Monthly fee | $3 per active card | $15 for 1–5 cards; $3 per active card after 5 |
| Setup fee | $35 | $35 |
| Approval | Instant for most; no bank info needed | 1–7 days; proof of revenue |
| Spend limit | Whatever you load | Credit line set at application |
| Non-fuel purchases | Allowed by default | Subject to approval |
| Late payment fee (comparison table) | 0% | 5% |
For one truck, Unlimited is the cheaper card: $71 in year one ($35 setup plus 12 × $3) versus $215 for Flex ($35 plus 12 × $15). Flex only makes sense if you need to fuel on credit while you wait on broker payments. If you factor, check your factor’s fuel advance first; see factoring with fuel advances.
What 42¢ a gallon is worth
Example: 1,500 gallons of diesel a month (about 10,000 miles at 6.7 mpg, our assumption). At AtoB’s stated 42¢ average, that’s about $630 a month if every fill is at a partner stop. On Unlimited, the $3 card fee costs 0.2¢ a gallon; on Flex, $15 costs 1¢ a gallon. The fee matters far less than how many of your fills land in-network, so check AtoB’s station map against your lanes before you sign up. Run the numbers in the cost-per-mile calculator.
Fine print we found
- Two late-fee figures. AtoB’s comparison table lists a 5% late fee for Flex and 0% for Unlimited. The FAQ on the same page says the late penalty is 3% of the overdue balance, minimum $35. source Ask which applies to your account.
- Two “up to” discounts. The FAQ says discounts reach up to 84¢/gal on truck diesel; the footnote cites a maximum realized saving of $2.00/gal in H2 2025. The 42¢ average is the number to plan on. source
- Where discounts apply. AtoB names TA, Petro, TA Express, 7-Eleven, Speedway and RaceTrac among diesel partners. source
- Fraud protection. AtoB’s owner-operator guide states up to $250,000 in fraud protection, with app-based card unlock and real-time alerts. source
Who AtoB fits, and who should look elsewhere
- Good fit: owner-operators who fuel at many different brands and want one card that works everywhere; small fleets that want spending controls, telematics checks and IFTA exports; carriers building business credit.
- Look elsewhere if you want $0 monthly fees (TCS states no monthly fees; the Mudflap app is free with debit or ACH; see AtoB vs Mudflap), you fuel mostly at one truck stop chain where a network card states a deeper average, or you already factor with a company whose fuel card is bundled (for example OTR or Triumph).
