WEX vs Comdata Fuel Card: Discounts and Network Compared
WEX Fleet One EDGE and Comdata are both big legacy fleet cards. Here is how their fees, discounts, and networks really stack up, and who each one fits.
Quick verdict
WEX Fleet One EDGE wins on network size and IFTA reporting, so it is the stronger pick if you run a handful of trucks and want one card accepted almost everywhere. Comdata earns its keep when you push real diesel volume through TA/Petro and want factoring, cash advances, and driver ATM access on one platform. One caution for the solo owner-operator: both cards lean fleet-first and contract-heavy, so a no-fee card like TCS, AtoB, or Mudflap will often leave more money in your pocket.

Where WEX wins
WEX Fleet One EDGE runs on a network of 16,000-plus locations that covers about 95% of U.S. fuel stops, including Pilot, Love's, TA, Petro, Casey's, Kwik Trip, and AMBEST [1]. That is the wider acceptance of the two cards, and for a small fleet running mixed lanes, acceptance matters more than a headline rebate you can only earn at a few stops.
The per-card fee is also lighter. Independent comparisons put WEX around $2 to $4 per card per month, versus roughly $8 per card on the Comdata side plus a setup fee [2][3]. Spread that over a year and several trucks and the gap adds up.
WEX has the edge on IFTA and reporting too. It sends monthly IFTA-ready reports with state-by-state breakdowns, and it pushes alerts at the moment of purchase when a driver buys something off-policy [4]. Comdata reports as well, but WEX's purchase-time alerts work as a live fraud and policy check instead of a month-end statement you read after the money is gone.
On discounts, WEX EDGE advertises 3 to 15 cents per gallon at in-network EDGE stops, dropping to 1 to 3 cents outside the network [1]. Be realistic about that range. The 12 to 15 cent figure is reachable at the right stops, but the top 15 cents only lands at locations offering the maximum rebate. NASTC members and factoring-bundled accounts report deeper savings at participating stops.
Where Comdata wins
Comdata has been a truck-stop fixture for decades, and at 8,000-plus locations it is strongest exactly where over-the-road trucks fuel: TA/Petro, Pilot/Flying J, and Love's [3][5]. If your trucks live on those chains, Comdata's in-network pricing is hard to beat, because it bills you the cash price instead of the credit price. That alone can run 10 to 20 cents per gallon cheaper before any rebate.
For higher-volume fleets, Comdata's discounts scale up. Smaller fleets typically see $0.05 to $0.15 per gallon, while larger fleets on Cost-Plus pricing can reach $0.25 to $0.50 or more per gallon at in-network stops [5]. If you are buying serious diesel every week, that tiered structure rewards you in a way WEX's flatter EDGE range does not.
Comdata also bundles more money tools onto the same platform: factoring, cash advances, and driver ATM access [5]. For a fleet that wants fuel and factoring and driver pay tied together, that consolidation is worth something real.
The honest part: customer service and contracts
Neither card has a clean reputation with small operators. Comdata sits around 1.4 out of 5 on Trustpilot, with recurring complaints about hold times stretching from 45 minutes to over an hour [3]. WEX is no better on the review side. Its BBB customer review average sits near 1.0 out of 5, with complaints clustered around billing transparency and slow fraud-claim resolution [6].
Both cards lean on credit checks and personal guarantees, and both have fee structures that are hard to pin down before you sign. WEX in particular is known for fees and discounts that vary by product and by agreement, so you cannot pull a public rate card and know your number ahead of time. Read the agreement closely and get your per-gallon and fee terms in writing.
Verdict by scenario
For a larger fleet (10-plus trucks) buying heavy volume through TA/Petro and Pilot, Comdata's tiered Cost-Plus discounts and bundled factoring usually come out ahead.
For a factoring-tied operation, go with whichever card your factor already integrates with. Both WEX Capital and Comdata offer factoring that can feed rebates back to the fuel card, so let your existing money flow pick the winner.
For a small fleet (2 to 9 trucks) that values wide acceptance and clean IFTA reporting over squeezing out the last cent, WEX Fleet One EDGE is the more practical card.
When neither fits: the solo owner-operator
If you run one or two trucks, both WEX and Comdata are built for fleets bigger than yours. The per-card fees, setup costs, and contract terms eat into margins that are already thin. A solo owner-operator is often better served by a no-fee card like TCS, AtoB, or Mudflap that skips the monthly charge and still posts solid discounts at the major chains.

Frequently Asked Questions
- Is WEX or Comdata cheaper?
- On the per-card fee, WEX Fleet One EDGE is cheaper, running roughly $2 to $4 per card each month versus about $8 per card plus a setup fee on the Comdata side. On the fuel itself, the answer flips with volume. A high-volume fleet fueling at TA/Petro can often pull a deeper per-gallon discount from Comdata's tiered Cost-Plus pricing, while a small fleet with mixed lanes usually nets more from WEX's wider acceptance.
- Which has the bigger fuel network, WEX or Comdata?
- WEX. The Fleet One EDGE network spans 16,000-plus locations covering about 95% of U.S. fuel stops, including Pilot, Love's, TA, Petro, Casey's, and Kwik Trip. Comdata is accepted at roughly 8,000-plus truck stops and is strongest at the major chains where over-the-road trucks already fuel, but its raw footprint is smaller.
- Can an owner-operator get a WEX or Comdata card?
- Yes, both will work with owner-operators. WEX issues a credit-based card after a credit check and personal guarantee. Comdata offers both credit accounts and a prepaid Connect Card, and the prepaid route is easier to qualify for. That said, both cards are built around fleets, so a solo operator should compare the monthly fees against a no-fee card before signing.
- Do WEX and Comdata require a contract and a credit check?
- The credit versions of both cards typically require a credit check and a personal guarantee, and terms are set in an agreement rather than a public rate card. Comdata's prepaid Connect Card skips the credit hurdle. Either way, get your per-gallon discount and every fee in writing before you commit, because the headline numbers vary by product and by the deal you negotiate.
- Which card has better IFTA reporting?
- Both send monthly IFTA-ready fuel reports, so neither leaves you doing it by hand. WEX has a slight edge because it provides state-by-state breakdowns and pushes real-time alerts at the moment of purchase when a driver buys something off-policy, which doubles as a fraud check rather than a month-end surprise.
- Is there a better card than WEX or Comdata for a single truck?
- Often, yes. For one or two trucks, the monthly per-card fees and contract terms on WEX and Comdata can outweigh the discount. No-fee cards like TCS, AtoB, or Mudflap skip the monthly charge and still post solid discounts at major chains, which usually leaves a solo owner-operator better off. Run the math at your real monthly gallons before deciding.
