WEX vs. Comdata: Fleet Fuel Card Comparison Guide [2026]

Whether you're looking to cut fuel costs, implement spending controls, or simplify fuel reporting, two of the most popular fuel cards are WEX and Comdata. While both cards offer powerful tools for fleet management, they serve different types of businesses: WEX is built for all types of fleets, offering flexibility across a wide network of gas stations, while Comdata is optimized for over-the-road (OTR) trucking fleets that fuel at truck stops.

In this guide, we’ll compare WEX and Comdata side by side, looking at acceptance, discounts, fees, reviews, fraud protection, controls, and more to help you decide which card is the best fit for your fleet.

WEX vs. Comdata: Overview

Use this chart to quickly compare the two fuel card companies. The data comes from their official websites and third-party review sites to showcase key differences.

WEX vs. Comdata: Accepting Locations 

The theme of this comparison article is that WEX is built for all types of fleets while Comdata is made for trucking fleets and more specifically over-the-road (OTR) trucking fleets. WEX is made for businesses that want the flexibility to fuel at any station, which is why WEX is accepted at 95% of stations nationwide.

On the other hand, Comdata is designed for trucking companies that primarily fuel at truck stops due to the size of their vehicles and added driver conveniences such as overnight parking, food, and showers. As a result, Comdata is mainly accepted at truck stop locations. To expand it's acceptance, Comdata also offers an optional Mastercard add-on, enabling purchases anywhere Mastercard is accepted. However, fees and discounts can differ between transactions made on the Comdata network and those processed through the wider Mastercard network.

✅Pro tip: If your business needs more station flexibility, WEX is the better option. However, if your fleet mainly fuels at truck stops, Comdata is the ideal choice.

WEX vs. Comdata: Discounts 

WEX's discount program has a few layers. You can earn 3-15¢ per gallon at stations in the WEX Nationwide Savings Network. If you fuel outside that network, you’ll get a volume based rebate of 1-3¢ per gallon, depending on how many gallons you buy each month at eligible locations. WEX also offers brand-specific cards where you can save up to 8¢ per gallon when you fuel at participating branded stations.

The Comdata fuel card delivers substantial savings at truck stops by offering exclusive discounts and allowing customers to pay the cash price through special merchant agreements, unlike most other fuel cards, including WEX, which are typically charged the higher credit price. The cash rate is typically 5-15¢ per gallon less than the credit price, and when combined with Comdata’s additional truck stop discounts, trucking fleets can see significant cost savings.

✅ Pro tip: If your fleet primarily fuels at truck stops, Comdata is the easy choice. If your business fuels at gas stations, WEX will offer more discount locations.

WEX vs. Comdata: Fuel Card Fees 

Comdata offers tiered plans with more features and support as you move up. Simple Saver is the entry-level option with no monthly fee, SmartFleet is the mid-tier plan at $8 per card per month, and Total Advantage is the top-tier package at $129 per month for the full account. WEX charges up to $4 per card per month and has several extra fees.

✅Pro tip: Calculate the total fees based on the number of cards you use and the stations where you fuel to estimate what you’ll pay with each card.

WEX vs. Comdata Reviews

WEX offers several financial products beyond fleet cards, so keep that in mind when reviewing their ratings. Their Trustpilot reviews are split between two profiles: WEX Capital and WEX. Comdata, on the other hand, holds a 1.4-star rating on Trustpilot. Be sure to read through customer comments to identify common trends.

✅Pro tip: Contact each fuel card company’s support phone line to test their customer service and see how quickly they can resolve issues.

WEX vs. Comdata: Fraud Protection

Both fuel cards offer mobile apps that allow drivers to authorize transactions at the pump, significantly reducing the risk of fraud. WEX uses a two-factor authentication (2FA) app that sends a code only when the driver is physically at a fuel station. Comdata offers a similar system for drivers to activate the card through the app, and the authorization automatically times out after fueling.

In addition, both cards include advanced fraud protection features that verify the truck’s location and fuel tank level before approving a transaction. WEX calls this technology SecureFuel, while Comdata refers to it as Proximity Solutions.

WEX vs. Comdata: Fuel Card Controls and Reporting 

When it comes to controls and reporting, both Comdata and WEX offer options that can be customized for your fleet's needs. You really can’t go wrong with either option.

✅Pro tip: Create a list of specific goals you want to achieve and ask the sales team how their fuel card can help you meet them. This ensures you get the features your business needs.

WEX and Comdata Alternatives

If WEX and Comdata don’t quite provide the solutions you are looking for, here are other fuel cards you should consider: 

CFN Fuel Card 

For trucking companies on the West Coast, consider the CFN fuel card, which provides access to the largest discount fuel network in the Western U.S. CFN is accepted at over 3,000 18-wheel access cardlock fuel stations and 65,000+ retail truck stops and gas stations. With more CFN cardlock locations than truck stops in the region, many fleets use the CFN card to save on fuel and maintain better control over their fuel purchases.

Voyager Fuel Card

For business fleets that need fueling options beyond truck stops, the Voyager fuel card is an excellent choice. Accepted at 97% of fuel stations nationwide and with no card fees, it offers both convenience and cost savings.

WEX vs. Comdata vs. Alternatives: Which Card is Best for Your Business?

The right fuel card for your business ultimately depends on your fleet’s fueling habits. If your team needs the flexibility to fuel anywhere, WEX stands out with nationwide coverage at 95% of U.S. stations. On the other hand, if your fleet fuels primarily at truck stops, Comdata can offer deeper savings through cash price access and additional per gallon discounts at major truck stop brands.

Beyond discounts and acceptance, both cards offer tools for fraud protection, driver controls, and reporting. While Comdata tends to have higher monthly card fees, WEX includes more line item charges, so be sure to calculate the total cost based on your fleet's fueling needs.
