When it comes to large-scale business operations, even the smallest costs can add up quickly. A well-known example comes from American Airlines: by removing just one olive from each passenger’s salad, the airline reportedly saved around $40,000 a year. The lesson is simple – improving profitability is not always about making dramatic changes. Sometimes, it means identifying the small, recurring costs hidden across everyday operations and finding ways to reduce them.

For businesses operating vehicle fleets, the biggest savings opportunities often come from fuel usage, vehicle maintenance, theft prevention, and labour-intensive processes. Telematics can help reduce these costs by giving businesses better visibility into how vehicles are driven, maintained, protected, and managed.

There is, of course, an upfront investment in purchasing and installing fleet management solutions. However, once businesses gain access to real-time vehicle and operational data, they can identify unnecessary fuel consumption, prevent avoidable breakdowns, improve stolen vehicle recovery, and automate time-consuming tasks.

WHAT ARE THE BIGGEST FLEET COSTS?

Fleet operating costs vary depending on vehicle type, fleet size, region, and business model. However, we noticed some expenses consistently have a major impact on overall fleet spending.

The main fleet operating cost areas typically include:

• Fuel consumption

• EV battery health management

• Vehicle maintenance and repairs

• Vehicle theft and security

• Driver, labour, and administrative expenses

Understanding where these costs come from is the first step towards reducing them. Let’s look at each area and see how telematics can help.

#1 REDUCE FUEL COSTS WITH FUEL MONITORING

When it comes to fuel – every saved drop counts. While fuel prices, taxes, and operating conditions vary from one region to another, controlling consumption is a universal challenge – and an opportunity for fleets to reduce costs through better monitoring and more efficient vehicle use.

With telematics systems, fleet managers can remotely monitor fuel consumption and identify where unnecessary usage may be occurring. One common cause is how the vehicle is being operated. Harsh acceleration, sudden braking, excessive idling, and similar bad habits can increase fuel consumption across the fleet. GPS trackers can help monitor driver behaviour continuously, giving fleet managers the data they need to identify inefficient driving patterns, encourage more economical driving, and improve fuel efficiency.

The same visibility can be used for fuel theft detection, which may otherwise remain unnoticed for a long time. By comparing fuel levels with vehicle location, mileage, and driving activity, fleet managers can spot unusual consumption patterns and investigate them before the losses accumulate.

What is more, an automated fuel tracking system helps streamline vehicle turnaround and ensures vehicles are ready for their next rental or assignment. This is especially valuable for rental and car-sharing companies, where even small delays can affect availability and customer experience. One way to achieve this is through smart refuelling tracking for rental cars, which brings fuel monitoring directly into the vehicle return workflow.

Different fleets may require different approaches to fuel tracking depending on their vehicles, operating conditions, and business needs. Fuel Control: What Solution To Choose? compares the available options, while Efficient Fuel Management Solutions provides a closer look at our solutions and their topologies.

HOW FLEET TELEMATICS HELPS TO MONITOR FUEL:

• Easy, remote fuel monitoring across the entire fleet

• Identification of inefficient driving behaviours that increase fuel consumption

• Detection of unusual fuel drops that may indicate theft or misuse

• Automated refuelling tracking to help improve vehicle turnaround times

  
  

#2 IMPROVE EV BATTERY MANAGEMENT AND LIFE

Electrifying a fleet can reduce dependence on fuel, but it also introduces a new set of cost and operational challenges. One of the most important is managing high-voltage batteries, as degradation can reduce driving range, increase maintenance needs, and eventually lead to costly replacement or unexpected downtime.

Telematics can help fleet operators monitor EV battery condition remotely using OBD data reading devices. By tracking the key EV performance indicators, fleet managers can better understand battery condition and identify changes over time. Parameters such as state of charge (SOC), state of health (SOH), and battery temperature provide a clearer picture of EV battery performance and degradation over time. Accurate SOC data can help optimise charging schedules and keep vehicles ready for use. At the same time, SOH and temperature monitoring can support proactive maintenance, help extend battery life, and reduce the risk of unexpected costly failures.

Similar challenges apply to electric micromobility, where fleet availability is directly linked to the customer experience. In an e-bike or e-moped sharing service, for example, users expect to use a vehicle for a short trip without staff involvement. GPS trackers make this possible while also giving operators visibility into location, speed, battery level, and potential maintenance issues. Teltonika’s e-bike and e-moped sharing solution demonstrates how real-time monitoring can help operators identify low-battery levels or servicing needs and keep more vehicles ready for use.

HOW TELEMATICS IMPROVES EV FLEET MANAGEMENT:

• Early identification of battery degradation and potential issues

• Optimisation of charging schedules and vehicle availability

• Support for proactive maintenance and longer battery life

  
  

#3 REDUCE MAINTENANCE COSTS AND PREVENT BREAKDOWNS

There’s a saying: “If it ain’t broke, don’t fix it.” It reflects the idea that something working well is often best left alone, as unnecessary changes can sometimes do more harm than good.

When it comes to vehicle maintenance, however, this approach can be costly. If problems are only addressed once a warning light appears on the dashboard or a vehicle has already developed a serious fault, unexpected breakdowns can follow. Businesses then face not only repair costs, but also the downtime, delays, and operational disruption.

An unexpected van breakdown for a delivery company can mean delayed deliveries and dissatisfied customers. Repeated service disruptions can damage trust and give customers a reason to choose a more reliable service provider.

By automating delivery fleet maintenance based on mileage or other vehicle parameters, businesses can reduce the risk of unexpected breakdowns, keep vehicles available, and maintain smoother operations.

For a large logistics company managing many trucks, a proactive approach to maintenance is essential. Imagine a vehicle starts showing early signs of a problem, but the driver ignores them because no warning indicators appear on the dashboard. Over time, the issue can escalate and eventually take the truck off the road for repairs.

With earlier visibility, this can often be avoided. Trackers that read diagnostic trouble codes (DTCs) directly from vehicles allow maintenance teams to identify potential issues remotely and plan servicing before faults become more serious. This helps reduce manual diagnostics, repair delays, and vehicle downtime. You can learn more on this topic in our Remote DTC Reading for Proactive Heavy Fleet Maintenance use case.

HOW TELEMATICS IMPROVES PREDICTIVE MAINTENANCE:

• Less need for manual diagnostics

• Prevention of unexpected breakdowns

• Less costly vehicle downtime

• Automation of maintenance schedules

• Remote monitoring of diagnostic trouble codes (DTCs)

  
  

#4 REDUCE VEHICLE THEFT AND IMPROVE STOLEN VEHICLE RECOVERY

Vehicle theft can result in major financial losses, vehicle downtime, replacement costs, and disruption to whole fleet operations. Telematics devices can help businesses strengthen vehicle security by detecting suspicious activity early and providing fleet managers with the information needed to react quickly.

GPS trackers can detect events such as unexpected towing, device unplugging, movement outside predefined geofences, or attempts to jam the GPS signal. Depending on the setup, these events can trigger alerts or additional security actions, such as activating an alarm or blocking the vehicle starter. Teltonika’s anti-theft and stolen vehicle recovery solution shows how these scenarios can be combined to help discourage theft, detect suspicious activity earlier, and give fleet managers more time to respond.

Additional protection can be provided by using a secondary hidden tracker. If the main GPS tracker is discovered, disconnected, or damaged, the backup device can activate and continue tracking the vehicle, helping fleet managers and authorities locate it.

More advanced tracking technologies can also support recovery when a stolen vehicle enters areas where satellite signals are unavailable, for example, underground parking lots. Trackers with dead reckoning use accelerometer and gyroscope data to estimate the vehicle's position when GNSS signals are lost or jammed. This helps extend the vehicle track closer to its possible hiding location and gives recovery teams more information about its direction of travel. You can learn more in our Enhancing Stolen Vehicle Recovery With Dead Reckoning Technology use case.

HOW TELEMATICS IMPROVES VEHICLE SECURITY:

• Detection of suspicious activity

• Alerts for towing, unplugging, and signal jamming

• Improved stolen vehicle recovery

• Continued tracking even when the GPS signal is lost

#5 REDUCE FLEET LABOUR AND ADMINISTRATIVE COSTS

Managing a fleet involves driver identification, working-time records, vehicle access, and compliance tasks, which can all require employee time. Telematics helps automate many of these processes, reducing manual work and allowing fleet teams to focus on more valuable tasks.

If the main goal is operational transparency, telematics devices can simplify driver identification and digital record-keeping. For example, Bluetooth® ID beacons can automatically identify which employee is using a vehicle and help create a digital record of driver activity. Teltonika’s wireless driver identification and time tracking solution shows how this can reduce manual identification and make working-time records easier to manage.

When regulatory compliance is the priority, a more specialised solution may be required. For EU commercial fleets, tachograph management is one example. Instead of physically accessing vehicles to download files, compatible Teltonika's PROFESSIONAL category trackers can collect tachograph data remotely. Together with TachoSync, downloads can be scheduled automatically, files can be centrally stored, and driver activity can be monitored with less manual work.

This is particularly relevant for international van fleets: since 1 July 2026, certain light commercial vehicles over 2.5 tonnes used in international transport are subject to EU tachograph requirements. Teltonika’s Digital Tachograph Monitoring and Remote Tachograph File Download for Vans use cases show how these processes can be automated.

For car-sharing and rental companies, automation can go beyond driver records and extend to vehicle access itself. Remote access and central locking control allow customers to pick up and return vehicles independently, reducing the need for employees to handle every handover in person. Teltonika’s car-sharing solution demonstrates how telematics can support 24/7 self-service reservations while reducing manual labour.

HOW TELEMATICS REDUCES ADMINISTRATIVE WORK:

• Automated driver identification

• Simplified digital working-time records

• Easier compliance through remote data collection

• Automated vehicle access for car-sharing and rental fleets
