Learn more about fleet fuel management systems
A fleet fuel management system (FMS) is a platform that gives fleets visibility into fuel usage, fuel spend, and fuel waste across every vehicle, replacing fuel cards and spreadsheets that only show what was purchased, not what was actually consumed.
Samsara's Fleet Fuel Management solution is more than just FMS software—Samsara combines fuel card transactions with real-time GPS tracking in one unified platform, so fleet managers see fuel purchases alongside vehicle location, tank levels, and diagnostics. This makes it possible to catch inefficiencies like excessive idling and unauthorized fuel activity as they happen.
Samsara offers an advanced fuel management system, enabling fleets to cut fuel costs, fuel waste, and fuel fraud. Samsara offers significant benefits, such as:
Buy fuel at the best price: Use fuel price overlays to coach drivers towards cost-saving fueling choices, such as preferred stations or in-yard fueling.
Minimize fuel waste: Improve fuel efficiency with weather-aware idling insights, driver alerts, and driver efficiency reporting.
Fleet benchmarks for fuel usage: Identify opportunities for improvement across key efficiency metrics by comparing against customizable peer groups. Use tags to create benchmarks for different groups within your organization.
Tackle theft and fraud: Prevent unauthorized fuel use with real-time theft alerts, vehicle proximity and fuel level rise detection, AI-powered receipt capture, and fuel card integrations.
Ensure compliance: Streamline IFTA compliance with Samsara's automated reporting. By reducing manual work, speeding up processes, and ensuring accuracy, you can save time and maximize tax savings with confidence.
A fuel card is a specialized payment card designed for businesses to manage and control fuel purchases for their vehicles. Unlike regular credit cards, fleet fuel cards offer features such as spending controls, detailed transaction data, and integration with fleet management systems.
Fleet fuel cards can be used at a wide network of fueling stations, providing convenience and flexibility for drivers and mixed fleets. Additionally, many fleet fuel card programs offer access to discounts and rebates, helping businesses save money on their fuel expenses.
Samsara offers one of the largest ecosystems of turnkey integrations designed to connect seamlessly with essential 3rd party applications, including integrations for fuel cards. With seamless connectivity and real-time data across your organization’s most critical tools, you can break down data silos and improve operational efficiency. Some fuel card integrations that Samsara offers include FLEETCOR, WEX Fuel Card, AtoB, Fleevo Fuel Analytics, Fleevo Fuel Card Connector, Relay Fuel, E.J. Ward (SimplyFuel Solutions), RoadFlex, Shell Fuel Card, Coast, Voyager, Allstar, Multi Service Fuel Card, SC Fuels, and more.
Customers like Alterman were able to unify their fleet tracking and fuel management by integrating Samsara and Coast. With this integration, Alterman gains real-time data, automated reconciliation, and improved receipt capture, unlocking an enhanced level of control across their fleet's fuel usage. As a result, Alterman is able to make smarter decisions across their fleet, helping them reduce fuel costs by 10%.
Preventing fuel card fraud requires catching suspicious activity before a transaction completes, not just reviewing it afterward. Samsara's Fleet Fuel Management solution enables fleets to track consumption of fuel by setting configurable alerts for sudden fuel level drops and cross-references fuel card transactions against vehicle location and tank capacity to flag purchases used for unauthorized vehicles or external tanks. Flagged events can be reviewed with AI Dash Cam footage and vehicle diagnostics to verify what actually happened before taking action.
For example, Alterman lacked visibility into fuel usage prior to Samsara. Without real-time data, Alterman faced increased administrative burden, higher fuel spend, and even potential fraud. By integrating Samsara and Coast, Alterman was able to transform their fuel management operations. By tracking fuel purchases through a driver's fuel card and setting controls like custom spend limits and verifying the vehicle's GPS location at the pump, Alterman is able to minimize unauthorized fuel purchases. As a result, Alterman saw a 10% reduction in fuel costs.
Fleets can reduce fuel costs by focusing on areas such as driver habits, vehicle upkeep, and smarter routing. Coaching drivers with driver behavior monitoring helps reduce speeding, harsh braking, and idling, which helps minimize fuel waste. Route optimization avoids unnecessary miles and delays, while proper tire pressure and regular maintenance keep vehicles running efficiently. In addition, smart fuel purchasing from using discount networks and watching for fuel fraud can help to improve cost-savings.
Samsara's Fleet Fuel Management combines real-time fuel and idling data with driver coaching and gamified incentives, like in-app Kudos and leaderboards, to reinforce fuel-efficient habits such as coasting and smoother acceleration. Fuel purchasing data feeds into the same platform used for routing and maintenance, so fleet managers can optimize routes and streamline preventive maintenance without switching tools.
Customers like Estes leveraged Samsara Fleet Telematics to gain immediate visibility into idling data, allowing them to take actionable steps from day one. By tracking idle events and coaching drivers accordingly, Estes saved over $3 million in fuel costs. With granular data, Estes reduced operational costs and improved the customer experience by enabling better tracking and more accurate delivery estimates, ensuring customers could rely on timely information on their shipments.
Idling can significantly increase fuel costs by wasting fuel while a vehicle isn't moving. Across an entire fleet, excessive idling can add thousands of dollars in unnecessary fuel expenses each year while also increasing engine wear, maintenance costs, and greenhouse gas emissions. Fleet managers can reduce fuel costs by tracking idle time with GPS fleet management software, setting idle alerts, coaching drivers to minimize unnecessary idling, and using automated reports to identify vehicles with excessive idle times. By reducing idle time, organizations can reduce their carbon footprint, increase fuel economy, lower operating costs, and extend vehicle lifespan.
Samsara's Fuel Management solution is more than just a telematics device—Samsara uses context-aware idling alerts that factor in weather, PTO status, location, and temperature to distinguish necessary idling from waste, paired with in-cab audio reminders to correct behavior in the moment.
For example, Gordon Food Service used Samsara to reduce its nationwide idle rate from 17% to under 5%, saving 2.6 million liters of fuel and $2.5 million annually.
IFTA (International Fuel Tax Agreement) compliance requires accurate records of miles driven and fuel purchased by jurisdiction, which is difficult to maintain manually across a large fleet. Samsara's Fuel Management solution automates IFTA reporting using the same GPS and fuel data already collected for fraud detection and efficiency tracking, so fleet managers aren't maintaining a separate system just for tax filing. With Samsara, data such as fuel purchases, vehicle location, and mileage all live in one platform, so discrepancies that could complicate a filing, like a purchase that doesn't match a vehicle's actual route, are easier to catch before they become a compliance issue.
Samsara offers an expansive integration ecosystem featuring over 350 API integrations through the App Marketplace, including integrations for fuel tracking.
Some fuel management integrations that Samsara offers include Vusion, WEX EFS SecureFuel and Fuel Tax Reporting, ProMiles, Flipturn, Fuel Smart, PowerFlex X, Link2pump, AMCS, RoadFlex, SimplyFuel Solutions, Tenstreet True Fuel, AtoB, Relay Pulse, TruckLogics, Idle Smart, and more.
