Cut fuel spend and prevent misuse with Coast and Samsara

Fuel costs are one of the biggest line items for fleet operators. As a large variable cost, it’s where a lot of revenue quietly disappears. Rising prices aren't just hitting your bottom line at the pump, they're also making your fleet a more attractive target for fraud.

Across the tens of thousands of fleets that run on Samsara, we see the same pattern: when fuel prices climb, fuel card misuse climbs with them. Data from Samsara's fuel card integrations tells a clear story: In an internal analysis of Samsara fuel card integrations, we observed that, on average, a 10¢ increase in the price of a gallon of diesel was associated with a roughly 9% increase in detected fuel fraud incidents. When prices rise, the incentive to commit fraud goes up. 

A fill-up on a day the truck wasn't out. A volume bigger than the tank can hold. A swipe in a town nowhere near the route. Instances of fuel misuse are common. And, more often than not, they’re only caught after the fact—by reconciling fuel card statements with their telematics data weeks later. This is the gap Coast and Samsara’s integration closes.

The real problem: Fragmented tools can’t keep up

Most fleets today manage fuel across multiple disconnected systems: a fuel card provider on one side, telematics data on the other, and a spreadsheet (or a lot of manual work) in the middle trying to reconcile the two. This is where fraud slips through.

Most fuel cards approve or deny transactions based on card-level rules alone. They have no awareness of what's actually happening at the vehicle at the moment of the swipe: whether the right driver is present, whether the vehicle is anywhere near the pump, or whether the transaction amount even makes sense given how full the tank already is. That means fraud is only detected after it's already happened. By the time you notice it, you may have lost thousands.

There’s a better way: Fuel management now lives in Samsara

Real-time visibility is the most effective way to get ahead of fuel fraud, and that's what Coast and Samsara work together to do. Coast is natively integrated with Samsara, bringing fuel card controls directly into the platform you already use to run your fleet. No switching tabs. No exporting CSVs. No reconciling two systems.

The benefit to you: when a Coast card swipes, Coast's authorization engine checks the transaction against live Samsara telematics before it clears. It helps prevent fraud before it happens and reduces the time you spend cleaning up statements after the fact.

More than 500 fleets are already running Coast and Samsara's native fuel management. Based on Coast customer surveys, participating fleets reported average savings of approximately 7.5%* on fuel costs per vehicle, while cutting nearly half the time they used to spend managing it.
