Expert Fuel is the long-standing enterprise incumbent in route-aware fuel optimization, scoped by Trimble's own materials at roughly 50 trucks and up and usually bought with a Trimble TMS. If that is not your fleet, or not your TMS, here is the rest of the field, categorized honestly: three other route-aware optimizers, one of them ours and flagged as such, plus the adjacent tools fleets compare without realizing they solve a different problem.

Route-aware fuel optimizer, continuous
The closest like-for-like replacement, and the one we make, so read this entry with that in mind. Flow does the same core job as Expert Fuel: it decides where each truck should fuel along the route it is already running, how many gallons to buy at each stop, and at what net price, using live prices, the fleet's own negotiated discounts, IFTA state tax differences, tank capacity, and hours of service.
Three differences matter when comparing the two. The plan is not computed once at dispatch and locked: Flow re-optimizes every active trip as the truck moves and surfaces a better stop mid-route when one appears. Price prediction accuracy is published in the dashboard in cents per gallon, which is a number most vendors in this category do not show. And 100% of claimed savings reconciled against actual fuel card transactions, so the savings figure is auditable rather than modeled.
Pricing is per truck per month and public: $25 per truck per month on Solo with no fleet minimum, $40 per truck per month on Growth, and Enterprise from $49 with managed ELD and TMS integration plus automatic replanning. most fleets dispatch their first optimized fuel plan within 48 hours. For fleets under the size Expert Fuel is scoped for, that difference in minimum commitment is usually the deciding factor.
Route-aware fuel optimizer, lightweight
The most common lighter-weight alternative fleets weigh against Expert Fuel. It recommends stops along the existing route rather than rerouting the truck, and it publishes its price, which Expert Fuel does not: $50 per truck per month as of August 2026.
The trade to understand is the same one that separates Flow from Expert Fuel: whether the plan updates once the truck is moving. Fleets evaluating both should ask each vendor directly what happens to a plan when the route changes at 2pm, and ask how a claimed saving is verified against the fuel card transaction that actually occurred.
Route-aware fuel optimizer, pre-trip
A newer entrant in the same route-aware category, built around producing one globally optimal plan for the whole trip before departure rather than evaluating stops individually. Its published materials describe connecting a fleet's existing chain contracts and solving for how many gallons to load at each stop so the truck reaches the next cheaper station.
Worth a look for fleets that want pre-trip optimization and already hold chain contracts. As with any vendor in this category, including us, the questions that separate them are what happens after the truck departs and how a savings claim is proven.
Fuel purchase optimization with mileage and IFTA
A long-established name in trucking software, offering fuel purchase optimization alongside commercial mileage, routing, and IFTA tooling. For carriers that already run ProMiles mileage for tax filing, keeping fuel optimization inside the same vendor is a legitimate reason to shortlist it.
Fleets choosing on that basis should still confirm the same two points they would put to Expert Fuel: whether the plan is revisited mid-trip, and whether savings are reconciled against real transactions or estimated from the plan.
Fuel discount network
Not a replacement for Expert Fuel, and included because fleets shopping this category routinely compare the two without realizing they solve different problems. Mudflap supplies discounts. An optimizer decides how to spend them.
For an owner-operator or small fleet with no negotiated contracts at all, a discount network is the faster win. For a fleet that already holds Pilot, Love's, TA, or fuel-card contracts, enforcing those on every load is usually worth more than adding another network.
Fuel cards and spend management
Every fleet needs one, and the discounts attached to the card are the raw material an optimizer works with, so this is a complement to Expert Fuel rather than an alternative to it.
The gap worth naming: a card tells you what was spent after the fact, and the savings figures card vendors report are calculated by the vendor with nobody checking. That is precisely the gap per-transaction reconciliation exists to close.
Head-to-head detail: ValveRide Flow vs Trimble Expert Fuel, vs Fuel Router, vs Mudflap, or the full category guide.
In the same route-aware fuel optimization category: ValveRide Flow, Fuel Router, OptiMile Pro, and ProMiles. Adjacent tools that fleets often compare but that solve a different problem: fuel discount networks such as Mudflap, and fuel cards such as AtoB, Comdata, and EFS, which supply discounts rather than optimizing how they are spent.
Yes. Trimble's own materials describe Expert Fuel as designed for fleets of roughly 50 trucks and up, typically as part of a Trimble TMS suite. ValveRide Flow starts at $25 per truck per month with no fleet minimum, and Fuel Router publishes $50 per truck per month as of August 2026. Both are route-aware optimizers rather than cut-down products, so a small fleet gets the same optimization logic a large one does.
It should not. Expert Fuel is generally bought alongside a Trimble TMS, which is part of why fleets on another TMS look for alternatives. Flow accepts dispatches from any TMS by webhook or API, including McLeod, TMW, Alvys, and Magnus, and delivers plans through the ELD, SMS, or email the fleet already uses. No fleet should have to change its TMS, its ELD, or its fuel cards to change fuel optimizer.
Route optimization decides the path a truck drives. Fuel optimization takes the route as given and decides where to buy diesel along it, how many gallons at each stop, and at what net price after discounts and state fuel tax. Expert Fuel and the alternatives listed here are fuel purchasing optimizers: the routes and the loads stay the same, the gallons get cheaper. Telematics platforms attack a third thing, how much fuel is burned, which stacks with purchase optimization rather than replacing it.
Ask every vendor on the shortlist the same two questions. First, what happens to a plan after the truck departs: is it recomputed as prices move and the route changes, or fixed at dispatch. Second, how is a claimed saving verified: is each recommendation matched to the actual fuel card transaction that followed, or is the number modeled from the plan. ValveRide Flow reconciles every claimed dollar against a real transaction and publishes price prediction accuracy in cents per gallon; a blended average across fleets on Flow is about $0.90 per gallon, which is an average and not a per-fleet guarantee.
Yes, and you should. A route-aware optimizer is not a fuel network and does not replace your cards. It enforces the contracts you already hold with Comdata, EFS, Relay, TCS, FleetOne, or directly with Pilot, Love's, and TA, by making sure trucks fuel where those rates actually apply.
