AtoB is a fuel card: it sets what a fleet pays at the pump, with discounts, spend controls, and FuelMap, which shows discounted stations on a map and along a route so the driver can pick a stop. ValveRide Flow decides where and how much each truck fuels, from the load, route, hours of service, and tank level, across the fleet's own contracts. Fleets can keep AtoB for paying and add Flow.
We make Flow. Every AtoB claim below comes from AtoB's own public website and help center and is dated in the sources note.
AtoB describes itself as a fuel card and financial services platform for fleets of every size. Its site lists fuel discounts, spend limits and merchant controls, telematics checks that block transactions away from the vehicle or beyond its tank capacity, IFTA transaction reports, instant payments, and fleet credit.
For finding a price, AtoB offers FuelMap in its app and dashboard. Its site says FuelMap pre-plans routes with stops at stations with the highest discounts and lowest retail cost, and its help center shows drivers filtering, sorting, and claiming an offer before they fuel. As a card with controls and a discount map, it is purpose-built.
Flow is not a card. For each dispatch it decides where the truck should fuel and how many gallons to buy at each stop, from the load and route, hours of service timing, ELD fuel level, live prices at 7,500+ US truck stops, IFTA state fuel tax across 48 states with data, and the fleet's own contract discounts on every card and chain it holds.
It re-plans for the whole trip, offers alternate stops when the plan changes, and watches for fuel theft on card transactions and parked trucks. The published result is about $0.90 per gallon saved, blended across live fleets over the trailing 12 months, and 100% of claimed savings reconciled against actual fuel card transactions.
A fuel card sets what you pay at a stop. Flow decides which stop and how many gallons. Keep AtoB for paying, controls, and its discounts; Flow plans each fill around the load, the route, the tank, state fuel tax, and the hours left on the clock, then sends the plan to the driver by SMS, email link, or in-cab message on Samsara and Isaac.
Nothing has to be replaced. Fleets keep their card, their contracts, and their TMS, and Flow takes dispatches by webhook or API. Flow does not pull AtoB in-app offer prices today; it plans against posted prices and the contract rates the fleet holds.
At 50 trucks and up, a map the driver checks is not a fuel program. Flow Enterprise makes the fuel decision centrally for every dispatch, with managed ELD and TMS integrations, automatic replanning, and an SLA, and it ties every claimed savings dollar to a fuel card transaction. Pricing is per truck, never per driver, scoped through a demo.
| AtoB | ValveRide Flow | |
|---|---|---|
| What it is | Fuel card and spend management platform, per its site | Fuel decision software for each dispatch; not a card |
| The decision it makes | What you pay at a stop; FuelMap shows discounted stations on a map and along a route, and the driver picks and claims an offer | Which stop each truck uses, how many gallons to buy there, and on which contract |
| Inputs to the plan | AtoB network prices and discounts; telematics location and tank-capacity checks on transactions, per its site | Load and route, HOS timing, ELD fuel level, live truck stop prices, IFTA state fuel tax, and contract discounts |
| Whose discounts | AtoB network discounts; AtoB says it can port existing discounts at partner merchants | The fleet's own contracts across every card and chain it already holds |
| IFTA | IFTA-eligible transaction reports, per its site | State fuel tax is priced into each stop choice before the fill |
| Proof published | Vendor-reported discount savings and customer case studies | about $0.90 per gallon saved, blended across live fleets over the trailing 12 months, reconciled against actual fuel card transactions |
AtoB characterizations reflect AtoB's own public website (atob.com home and Fuel Cards pages) and its help center Fuel Map guide as of October 19, 2026. Features change; verify current details with AtoB. No disparagement intended: a fuel card with strong controls is something every fleet needs.
AtoB is a fuel card. Its FuelMap shows discounted stations on a map and along a route, and its site says it can pre-plan stops at the highest-discount stations; the driver picks and claims the offer. ValveRide Flow decides where and how much each truck fuels from the load, route, hours of service, and tank level.
Most fleets need both jobs done. AtoB is how you pay: a fuel card with discounts, spend controls, and fraud protection. ValveRide Flow is how you decide: which stop and how many gallons for each truck on each dispatch, across your contracts, with IFTA tax and HOS timing in the math. Keep the card and add Flow.
Yes. Flow is not a card and does not replace one. Drivers keep paying with AtoB; Flow sends each truck a plan saying where to stop and how many gallons to buy, by SMS, email link, or in-cab message on Samsara and Isaac. Flow takes dispatches from your TMS by webhook or API.
At that size most fleets run a fuel card such as AtoB plus a central fuel decision. ValveRide Flow Enterprise plans every dispatch from load, route, HOS, and tank level, uses the fleet's contracts on every card, adds managed ELD and TMS integrations and automatic replanning, and reconciles savings against card transactions. Pricing is per truck.
The published figure is about $0.90 per gallon saved, blended across live fleets over the trailing 12 months. It is not a per-fleet guarantee: results depend on each fleet's lanes, contracts, and fueling habits, and every claimed dollar is reconciled against the actual fuel card transaction. Pricing is per truck, never per driver, with Enterprise for larger fleets.
