WEX vs. AtoB Fuel Card: Which Is Right for Your Fleet?

"Comparing WEX vs. AtoB fuel cards? Rastrac's AtoB integration saves up to 25¢/gallon and GPS-verifies purchases to block fraud. See which card fits your fleet."

  • WEX and AtoB serve different fleet profiles – choosing wrong costs you real money in fees and missed savings
  • AtoB (available through Rastrac) delivers up to 25 cents per gallon in savings plus cashback rewards with no hidden transaction or ACH fees
  • Rastrac’s GPS integration can verify that a tracked vehicle is physically present at the pump – and deny the transaction if it isn’t
  • AtoB fuel card activity reports to Experian, helping fleets build business credit history automatically
  • Fleets with 50+ vehicles may qualify for flexible payment terms beyond the standard weekly credit line

    The Fuel Card Decision Most Fleet Managers Rush

    A landscaping company running 18 diesel trucks, a marine recreation outfit managing fuel for pontoon boats, ski boats, and waverunners on a trailer fleet, a construction firm with 40 pickups – they all face the same decision when it’s time to stop manually tracking fuel receipts: WEX or AtoB?

    Both are legitimate options. But they’re built for different things, and the gap in real-world savings, controls, and fees is wider than most buyers expect going in. The wrong choice locks you into a structure that either limits where drivers can fuel up, piles on hidden fees, or leaves serious per-gallon savings on the table – and does nothing to stop fuel fraud when a card leaves the vehicle it’s assigned to.

    This post breaks down exactly how WEX and AtoB compare – and explains why Rastrac’s partnership with AtoB makes it the stronger choice for most commercial fleets.


What Makes WEX and AtoB Different in Practice?

WEX is a large, established fuel card network primarily used by enterprise fleets. It offers broad acceptance and integrates with many fleet management systems. For large, compliance-heavy operations – think national carriers or government motor pools – WEX’s depth of integrations can justify the complexity.

AtoB is built for the commercial fleet market that WEX often underserves: small to mid-size operations that need real savings without enterprise-level overhead. Key differences show up fast:

  • Acceptance network: AtoB runs on the Visa network, accepted at fuel stations nationwide. WEX uses its own proprietary network, which limits driver options in regions with sparse WEX-affiliated stations.
  • Savings structure: AtoB delivers up to 25 cents per gallon in discounts, plus cashback rewards. WEX discounts vary by negotiated contract and are often tied to volume commitments.
  • Fee transparency: AtoB charges no transaction fees, no ACH fees, and no high interest rates. WEX pricing structures frequently include per-transaction fees that erode per-gallon savings.
  • Credit building: AtoB reports card activity to Experian, helping fleets build business credit through routine fuel purchases. WEX does not commonly offer this.

For a fleet running 20 trucks averaging 600 miles per week each, 25 cents per gallon in savings adds up to thousands of dollars annually – before any cashback is factored in.

How Rastrac’s AtoB Integration Goes Beyond a Standard Fuel Card

Rastrac’s fuel card offering is built on the AtoB platform, but the integration runs deeper than savings and spending controls. Because Rastrac is also tracking the physical location of your vehicles in real time, the two systems can work together to verify that the vehicle assigned to a card is actually at the pump when a purchase is attempted – and deny the transaction if it isn’t.

Location-Verified Purchase Authorization

This is a capability that neither a standalone WEX card nor an unintegrated AtoB card can provide. Here’s how it works in practice:

  • A driver swipes the AtoB fuel card at a station
  • Rastrac checks the GPS location of the vehicle assigned to that card
  • If the vehicle is confirmed at or near that location, the purchase proceeds
  • If the vehicle’s GPS position doesn’t match – the card is being used in a different city, at a different station, or by someone who doesn’t have the vehicle – the transaction can be denied

For a fleet manager running service vans, box trucks, or a trailer rig hauling a wakeboard boat or personal watercraft to a client waterfront property, this closes a major fraud gap. Cards get borrowed, lost, or taken. Without GPS verification, you wouldn’t know a card was misused until the billing cycle closed. With Rastrac’s integration, unauthorized transactions don’t go through in the first place.

Spending Controls That Actually Work

Rastrac’s AtoB fuel card also gives fleet managers full control over how and when cards can be used:

  • Set per-transaction spending caps by driver or by vehicle
  • Restrict purchases to fuel only – block non-fuel items at the pump
  • Define approved purchase hours (no after-hours fueling on company cards)
  • Limit accepted merchant categories

This level of control matters for mixed fleets. An operator managing pickup trucks, cargo vans, and a trailer rig hauling a pontoon boat or ski boat needs different rules per vehicle – not a blanket limit that either over-restricts or leaves gaps.

Payment Terms Built for Your Fleet Size

  • Standard fleets operate on a weekly credit line with end-of-week payment
  • Fleets with 50 or more vehicles may qualify for more flexible terms
  • Fleets not approved for a credit line can use a prepaid option – no exclusions for newer businesses

WEX credit approval and terms tend to favor established enterprise accounts. AtoB’s structure accommodates growing fleets that haven’t yet built the credit history WEX underwriters want to see.

Reporting That Replaces the Receipt Box

Both platforms offer digital reporting, but the practical difference is integration. Rastrac’s AtoB fuel card connects financial spend data to the same ecosystem as your GPS tracking:

  • Driver-level fuel purchasing patterns visible in one dashboard
  • Cross-reference fuel card transactions against vehicle GPS history to flag discrepancies
  • Exportable data for accounting and tax purposes
  • No paper receipt collection, no manual entry

When fuel spend and location data live in the same platform, fraudulent or accidental misuse becomes visible immediately – not weeks later at billing review.


Which Fleets Should Choose AtoB Over WEX?

AtoB through Rastrac is the stronger fit for:

  • Small to mid-size commercial fleets (5–200 vehicles) that need real per-gallon savings without enterprise contract commitments
  • Mixed asset fleets including trucks, vans, trailers, and equipment transport rigs – including operations that haul personal watercraft like ski boats, waverunners, jetskis, or wakeboard boats to job sites or client locations
  • Fleets concerned about fuel card fraud where GPS-verified purchase authorization prevents unauthorized transactions before they process
  • Growing businesses that want to build Experian business credit while managing day-to-day fuel costs
  • Operations already using Rastrac GPS tracking, where unified dashboards reduce administrative overhead

WEX may be worth evaluating if your fleet is 500+ vehicles with existing WEX integrations, you operate in a vertical where WEX’s compliance reporting is a contractual requirement, or your enterprise ERP is already deeply connected to WEX’s API.

For the vast majority of commercial fleets, AtoB’s combination of nationwide Visa acceptance, up to 25 cents per gallon in savings, zero hidden fees, Experian credit reporting, and GPS-verified transaction authorization makes it the more practical and more profitable choice.

FAQ

Q: How does Rastrac verify that the right vehicle is at the pump before approving a transaction?

A: Through the Rastrac and AtoB integration, a fuel card purchase attempt can be cross-referenced against the real-time GPS location of the vehicle assigned to that card. If the vehicle’s tracked position doesn’t match the purchase location, the transaction can be denied before it processes – stopping misuse before it hits your billing cycle.

Q: Does AtoB work at any gas station, or only certain chains?

A: AtoB runs on the Visa network, which means drivers can fuel up at virtually any gas station in the country, not just stations affiliated with a specific chain. This matters for fleets operating across multiple states or in regions where chain-specific cards leave drivers without options.

Q: How does Rastrac’s fuel card handle fleets that mix vehicle types?

A: Rastrac’s AtoB fuel card lets you issue cards by driver or by vehicle and set independent spending controls for each. Whether you’re managing a pickup truck, a box van, or a trailer rig hauling a pontoon boat or waverunner to a client site, you can configure separate rules per card.

Q: Does AtoB charge transaction fees like some WEX plans do?

A: No. Rastrac’s AtoB fuel card has no transaction fees, no ACH fees, and no high interest rates. The savings structure is straightforward: up to 25 cents per gallon in discounts plus cashback, with transparent monthly fees and no surprises at billing.

Q: How long does it take to start saving after signing up?

A: Savings start from the first fuel purchase. Once cards are issued and spending controls are configured in Rastrac, drivers can begin fueling immediately. Drivers also become eligible for additional discounts through the AtoB app after 90 days of card use.
