AtoB Fuel Cards Review (2026 Guide)

Pros

• Widespread acceptance at virtually all pumps
• Impressive discounts of around $0.45 at truck stops
• Modern fraud defenses like SMS unlocks, GPS and radius checks, and telematics-driven rules
• Clear, scalable pricing with both card options

Cons

• Modest gasoline rebates
• Strict late fees

Both AtoB card types have a $35 setup charge. AtoB Flex costs $15 per month for the first five cards and $3 for each card beyond that. AtoB Unlimited is $3 per active card per month. Optional premium features that expand security and controls are an additional $3 per month per card.

AtoB generates weekly statements, with payment due based on your billing terms. If payment is late, a 9% fee (minimum $99) applies immediately, followed by another 6% fee (minimum $99) if unpaid after 30 days. Set up autopay and alerts early to avoid these penalties.

Some Flex applicants may start in a Credit Enablement phase, which adds a temporary per-gallon surcharge until you've demonstrated on-time payments. Ask whether this applies to your account during onboarding.

AtoB cards are issued by Celtic Bank and run on the Mastercard network, meaning they’re accepted almost everywhere fuel is sold.

How Much Fuel You Need To Break Even

The table below shows how many gallons your drivers need to purchase each month to offset the card fees based on typical fuel discounts. This break-even analysis assumes average savings for both unleaded and diesel fuel at AtoB partner stations.

• AtoB Flex: Weekly‑billed credit line for fuel and vehicle‑related purchases. Fleets are approved based on weekly fuel and maintenance spend, enabling drivers to use the card with flexible repayment after the billing cycle closes. It supports Mastercard acceptance everywhere, deep fuel discounts at partner stations, and advanced fraud and spending controls. Onboarding requires approval, and you’ll receive a monthly statement that must be paid in full under your credit terms.
• AtoB Unlimited: Prepaid card option ideal for fleets seeking no‑credit‑check flexibility. You preload funds into the AtoB wallet and issue cards immediately. It supports the same broad Mastercard network, offers similar discount potential, and builds business credit without traditional credit‑line approval. It’s well suited for smaller fleets, contract drivers, or entities preferring prepaid control over open credit.

Comparing AtoB Fleet Fuel Card Options

• Extensive network: The Truck Stop Discount Network spans brands like TA, Petro, TA Express, 7‑Eleven, Speedway, Kwik Trip, and RaceTrac.
• Diesel savings: Diesel discounts commonly average $.40 per gallon, with occasional regionally higher peaks of up to $2 at select stops
• FuelMap and price routing: Within the driver app, FuelMap steers drivers to lower-priced stations nearby. AtoB markets roughly $0.21 per gallon in additional savings by optimizing where you fill.
• Customizable card controls: Set rules for where, when, and how cards can be used — including merchant whitelists, day/time restrictions, and per-fill or weekly spending limits.
• Secure Card Unlock: Require drivers to unlock their cards through the mobile app before each purchase, reducing unauthorized use and enforcing driver accountability.
• Telematics-driven enforcement: Use real-time vehicle data to automatically decline transactions when the vehicle isn’t at the pump or to flag suspicious top-offs and fuel container fills based on tank level.
• AtoB Perks: Includes cash-back and partner deals for trucking services, which can add incremental value for over-the-road operations.

AtoB fits fleets that want universal acceptance without giving up strong controls. It is particularly attractive for operators who can consistently tap partner diesel locations on their real routes.

These types of trucking operations should consider AtoB fleet fuel cards:

• OTR and regional diesel fleets: Truck stop discounts are the primary source of savings. Fleets that refuel at TA, Petro, and similar brands will see the greatest impact.
• Price-sensitive operators: FuelMap and broad acceptance help drivers reach cheaper stations nearby rather than detouring, which boosts real-world savings.
• Firms building business credit: Both Flex and Unlimited report to Experian, which can help younger companies establish credit history with consistent on-time payments.

• Ask about your underwriting path. Confirm whether you’ll start on a Credit Enablement track so you can factor in any temporary per-gallon surcharges.
• Review all applicable fees in writing. Get clear documentation on setup, monthly, and premium feature fees — and understand how they’ll scale with card volume.
• Estimate your active card count. Since AtoB applies charges based on “active” cards, calculate how many drivers will transact weekly to forecast monthly cost accurately.
• Clarify billing terms and due dates. Know when weekly payments will be due and confirm whether autopay is enabled by default.
• Model savings based on route coverage. Look at AtoB’s partner discount map to compare your routes against expected savings, especially for diesel fleets.
• Compare card options based on your cash-flow needs. Choose the credit or prepaid option based on whether your business prefers paying weekly or loading funds upfront.
• Ask about integration support. If you use telematics or accounting software, confirm how easily AtoB data syncs with your existing systems.

We consider AtoB one of the best fleet fuel cards for its combination of strong diesel discounts and outstanding fraud prevention. It’s accepted almost everywhere, offers meaningful savings at partnered truck stops, and gives fleets powerful, telematics-driven control over spending. Gasoline rebates are smaller and late fees can add up, but both are easy to manage with partner routing and autopay enabled.
