If you’re considering a Comdata fuel card or already using one and exploring other options, it’s worth comparing how it stacks up against other fleet cards. Comdata is widely used by trucking fleets for its truck stop discounts and control features, but it may not be the best fit for every operation.
Some business fleets may prefer a card with fewer fees, broader acceptance beyond truck stops, or a different pricing model.
This guide highlights some of the best Comdata fuel card alternatives to consider. Instead of repeating a full Comdata review, we’ll compare five options for fleet managers to evaluate when they want different pricing structures or more flexibility in where they fuel.
| Fuel Card | Discounts | Monthly Fee | Late Fee | Accepting Locations | Trustpilot Rating |
| Mudflap | Estimated 57¢/gal at 3,600 in network locations, 2¢/gal everywhere else | None | 3-6% | Anywhere Visa is accepted | 4.4/5 |

| Voyager | 3-8¢/gal at select locations | None | None | 97% of gas stations and truck stops | 4.8/5 |
The Mudflap fuel card is a Visa fleet card designed for owner-operators and small to mid-sized trucking fleets that want to get discounts at truck stops. It has no monthly fees and provides discounted fuel pricing at more than 3,600 in-network truck stops, where fleets can access some of the strongest per gallon discounts in the market.
Because the card runs on the Visa network, it can be used at any location that accepts Visa, giving fleets nationwide coverage. However, the largest discounts are within Mudflap’s in-network truck stop locations, while out-of-network purchases receive smaller savings.
| Mudflap | Comdata | |
| Accepting locations | Anywhere Visa is accepted | 8,000 truck stops |
| Discounts | Estimated 57¢/gal at 3,600 in network locations, 2¢/gal everywhere else | Cash price and 8-40¢/gal at select truck stops, custom discounts for fleets with more than 20 vehicles |
| Monthly fee | None |
Monthly plan level options:
|
| Late fee | 3-6% | 13.99% |
| Trustpilot rating | 4.4/5 | 1.4/5 |
Good fit if: You want a fuel card that gets strong discounts at truck stops like Comdata, but without the monthly fees.
The EFS fuel card is one of WEX's over-the-road (OTR) trucking focused fleet cards designed for mid-sized and large fleets that want access to a network of 16,000 truck stops nationwide. EFS provides fuel pricing based on customer agreements, offering cash price at in-network truck stops, with discounts and fees that vary depending on the size of the fleet and negotiated terms. This makes it a flexible option for fleets that want custom pricing tailored to their fuel volume and operations.
| EFS | Comdata | |
| Accepting locations | 16,000 truck stops | 8,000 truck stops |
| Discounts | Cash price at in-network truck stops, discounts vary by customer agreement | Cash price and 8-40¢/gal at select truck stops, custom discounts for fleets with more than 20 vehicles |

In-depth comparison: EFS vs. Comdata
Good fit if: You operate a mid-sized to large fleet and want a fuel card that runs on a dedicated fuel network like Comdata, but has different fees, discount opportunities, and more accepting locations.
3. CFN
The CFN fuel card is designed for business fleets in the Western U.S., with a focus on cost-plus fuel pricing at 3,000 cardlock locations, primarily in California, Oregon, Washington, Arizona, and Nevada. It also provides access to 65,000 gas stations and truck stops nationwide, giving fleets coverage for both local and regional operations.
CFN is widely used by fleets in the West because there are more cardlock locations with 18-wheel access than traditional truck stops, and pricing at these CFN sites is often lower than retail fuel prices. The card also has no monthly or late fees, making it a straightforward and cost-effective option for fleets that want consistent access to discounted fuel without ongoing account costs.
| CFN | Comdata | |
| Accepting locations | 3,000 discount locations; 65,000 gas stations and truck stops | 8,000 truck stops |
| Discounts | Estimated 35¢/gal at discount locations | Cash price and 8-40¢/gal at select truck stops, custom discounts for fleets with more than 20 vehicles |
| Monthly fee | None | Monthly plan level options:
|
| Late fee | None | 13.99% |
| Trustpilot rating | 4.8/5 | 1.4/5 |
Good fit if: Your company operates diesel vehicles in the Western U.S. where you can benefit from CFN’s strong coverage of 18-wheel-access stations and its cost-plus fuel pricing.
AtoB is a fintech company that offers a fleet fuel card accepted nationwide on the Mastercard network. It’s built for both business fleets and trucking companies. While the card works at most fuel stations, the strongest discounts are typically found at truck stops, making it a good fit for over-the-road (OTR) fleets that fuel frequently at major truck stop chains.
| AtoB | Comdata | |
| Accepting locations | Anywhere that accepts Mastercard | 8,000 truck stops |
| Discounts | Estimated 45¢/gal on diesel at truck stops; estimated 5¢/gal at gas stations | Cash price and 8-40¢/gal at select truck stops, custom discounts for fleets with more than 20 vehicles |
| Monthly fee |
|
Monthly plan level options:
|
| Late fee | 9% | 13.99% |
| Trustpilot rating | 4.7/5 | 1.4/5 |
Good fit if: You want a more tech-focused fuel card that offers truck stop discounts and features built for over-the-road (OTR) operations. The prepaid fuel card option is also nice for businesses that don't want a credit line or don't have established credit.
The Voyager fuel card is accepted at over 97% of gas stations and truck stops nationwide, including major brands and independent locations. Its broad acceptance makes it a strong fit for fleets that need to fuel in both urban and remote areas. It also gives you the flexibility to choose the lowest-priced stations instead of being limited to a smaller network with fewer options.
| Voyager | Comdata | |
| Accepting locations | 97% of fuel stations nationwide | 8,000 truck stops |
| Discounts | 3-8¢/gal at select locations | Cash price and 8-40¢/gal at select truck stops, custom discount plan for fleets with more than 20 vehicles |
| Monthly fee | None | Monthly plan level options:
|
| Late fee | None | 13.99% |
| Trustpilot rating | 4.8/5 | 1.4/5 |
Good fit if: Your business needs a fuel card without monthly fees or late fees that can be used almost anywhere and still has the controls that come with a fuel card that runs on a dedicated fuel network. It’s also a good fit if your fleet doesn’t regularly fuel at truck stops where most of Comdata's discounts are focused.
