Your fuel discounts aren't making it to the pump.

Two ways. First, we make sure your existing fuel contracts actually get used on every dispatch. Most fleets negotiate good rates with Pilot, Love's, TA, or their fuel card vendor, but drivers don't always end up at the right stop, so the discounts never land. Second, we factor in fuel tax differences between states: fueling in a $0.21/gal tax state instead of a $0.45/gal state on the same corridor changes the math. Combined, fleets see about $0.90 per gallon, blended across live fleets, trailing 12 months in reconciled savings, and every claimed dollar is checked against an actual transaction.

Three things, and they are related. First, almost every fuel tool builds one plan at dispatch and locks it. Flow keeps replanning for the entire trip: when the route changes, when truck stop prices move during the day, when the driver takes a different stop, or when the hours-of-service clock shifts, the plan is rebuilt against where the truck actually is. A plan that was optimal at 6am is frequently not optimal by the second fill. Second, most tools still plan one trip at a time. Flow looks forward: if another load is already queued, today's plan arrives with the fuel that next leg actually needs, including the empty miles between drop and pickup, instead of leaving the truck to buy expensive fuel tomorrow. Third, Flow is built to connect the way you already work rather than the other way around. Your TMS can post loads to a webhook or call the API; the plan can reach the driver through in-cab ELD messaging, SMS, or an email link; and the same engine is available inside ChatGPT and over the Model Context Protocol. No fleet has to change its ELD, its TMS, its fuel cards, or its dispatch workflow to run Flow.

Most fleets dispatch their first optimized fuel plan within 48 hours. The work is connecting your ELD (we integrate directly with Samsara, Omnitracs, Isaac, and Motive), syncing your fuel card transactions (Comdata, EFS, Relay, TCS, FleetOne), and loading your contract rates. On Enterprise, we run all the integrations for you.

Yes. Flow is built around a webhook: your TMS posts a load to our endpoint and gets an optimized fuel plan back within two seconds. The plan goes straight to the driver's ELD messaging, right alongside the dispatch info they already see, so nobody has to learn a new app or check a separate screen. We have direct integration patterns for the major TMS platforms, plus a generic webhook for anything else. For medium and large fleets, the Enterprise plan automates the whole thing end to end.

No. This is the thing fuel-network apps get wrong. Flow works with every vendor and every contract you already have: Pilot, Love's, TA, Petro, Kwik Trip, your direct fuel terminal supply, anything. We're not selling fuel. We're optimizing the spend across whatever network you've already negotiated.

We publish the answer in your dashboard. For every fueling at a recommended stop, we measure our predicted price against the actual pump price. You see mean error in cents per gallon, percentage of predictions within 5¢, and percentage within 10¢. Most vendors hide this number. We lead with it.

Two things. First, we score whether the off-plan stop cost the fleet money or saved it. Sometimes drivers find a better deal, and we credit them for it. Second, the off-plan analysis tells us where our price feeds need work, so we keep getting better. You see both lists in your dashboard.

Yes. Every active trip is watched against its planned route. When a truck drifts off and stays off (sustained across consecutive position pings, so a single GPS blip won't trip it), the trip gets flagged for review. On Enterprise, an off-route trip can also trigger an automatic replan from the truck's live position, routed on commercial truck routing with mileage validated against the standard your TMS and IFTA filings already run on. Growth gets the same off-route alerts.

It keeps optimizing. Most fuel tools build the plan at dispatch and lock it. The moment prices move, the truck drifts, or the HOS clock shifts, that plan is stale, but the driver is still following it. Flow re-checks the trip as the truck moves, weighing live prices, your discounts, the truck's position, and hours of service, and surfaces a better stop mid-route the moment one shows up. It also flags missed fuel stops, when a truck rolls past an optimal stop without fueling, so dispatch can recover the savings on the next fill.

Vendor savings claims are calculated by the vendor, with nobody checking their math. Flow reconciles every transaction against the recommendation that triggered it: the driver's actual stop, our recommended stop, miles of deviation, net dollars saved or lost. Every row is something you can check. If we say we saved you $X, you can click through and see the trip.

Two watches, because fuel goes missing two different ways. On the card: Anomaly Watch runs eight detectors on every transaction your fleet posts, covering tank overfills, impossible-distance fuelings, double swipes, after-hours fueling, repeat-station habits, sudden discount shifts, off-trip patterns, and off-dispatch fueling. That is the half that surfaces compromised cards, friends-and-family fill-ups, and driver diversion. On the tank: the parked-truck fuel watch reads fuel level from the ELD and flags a drop that happens while the truck is sitting still with no matching card fill, which is the theft that never leaves a transaction behind to detect. Both hand you things to review. Not accusations, just the patterns worth a look.

Yes. Flow reads fuel level from the ELD. When a tank drops while the truck is parked and there is no matching fuel card fill, we surface it for review. That sits next to Anomaly Watch on fuel card transactions (overfills, double swipes, after-hours, and related patterns). Both are review queues, not automatic accusations.

Yes. The Discount Opportunities view in Analytics ranks the truck stops your fleet already fuels at most, by real spend from your fuel card transactions, and quantifies your leverage at each one: visits, gallons, share of your fleet's spend, and what every cent per gallon of discount is worth to that location per year. Flow also generates a print-ready Fuel Volume Summary one-pager you can bring to the truck stop or email to a regional rep when you ask for a fleet rate. Independent truck stops negotiate directly, and a fleet that shows up with twelve months of committed volume on paper gets a very different conversation than one that just asks.

Yes. Flow imports your trailer roster from your telematics, tracks live reefer fuel levels, unit power, set points, and alarms, and shows reefer fuel next to tractor fuel on every dispatch plan. For temperature-protected loads, reefer-protective planning adds top-off guidance at planned fuel stops and places stops so the reefer is refilled before its safety buffer runs out, because a reefer that runs dry on a protect load is a cargo claim, not an inconvenience. Flow is also load-aware: a reefer trailer pulling a dry backhaul with the unit off is treated like a dry van, so drivers aren't nagged about a reefer that isn't running.

$40 per truck per month on the Growth plan, or $25 per truck per month on Solo for owner-operators and small fleets up to 9 trucks. Enterprise, for medium and large fleets that want automated TMS-to-engine dispatch, fully managed integrations, and volume pricing, starts at $49 per truck per month and is scoped through a demo.
