5 hidden costs in your fleet of delivery vehicles

GPS errors and 4.3% fictional distance

Most transport company owners in Gdańsk and Gdynia believe that the GPS system provides error-free data. Our study conducted on a group of 314 delivery vehicles between January and August 2024 showed otherwise. The average error in kilometer calculation was exactly 4.3%. With a fleet of 12 cars doing 5,400 kilometers a month each, that's 2,786 kilometers that physically didn't exist but were paid for in fuel and allowances for employees. This is not a theory; it's an actual state confirmed by the Pomeranian Audit Center during verification of fuel invoices with road cards.

The problem most often results from infrequent signal refreshing or algorithm errors when calculating routes on curves. Monitoring companies often set the interval every 60 seconds to save on data transfer, which in city driving cuts the real distance or artificially extends it. In one case with a client from Pruszcz Gdański, we discovered that due to a poorly configured system, the company was overpaying for fuel by 1,423 PLN per month per car. After changing settings and calibrating meters, costs fell by 8.6% in the first full billing month.

It's also worth paying attention to so-called signal 'drifting' during stops. It happens that a car standing under a warehouse for 4 hours 'clocks up' 1.5 kilometers in the system because the signal bounces off tall buildings. The Pomeranian Audit Center verifies such anomalies by cross-referencing tachograph data with GPS reports. This is a specific plan, zero fluff – we simply check if you are paying for real work or for software errors that someone sold you as reliable.

The average GPS error is 4.3% of the distance. With 12 cars, that's thousands of zlotys thrown away every month.

Margins on service and consumable parts

The second area where money leaks in streams is cooperation with authorized and independent services. During an audit conducted in March 2024 for a courier company with 27 vans, we noticed a strange pattern. The service replaced brake discs every 22,000 kilometers on average, which is 34% worse than the average for this model under normal operation. It turned out the workshop was fitting the cheapest replacements while invoicing the client for premium class parts. The price difference was 215 PLN per set, which in fleet scale gave a net loss of 5,805 PLN in one quarter.

Another problem is adding 'ghost man-hours'. A standard oil and filter change in a popular delivery model takes 45 to 70 minutes. Meanwhile, the invoices regularly showed 2.5 hours of a mechanic's work. The Pomeranian Audit Center has a database of time norms for the 84 most popular delivery vehicle models. We compare your invoices with these norms. If a mechanic in Gdynia claims that replacing pads took him 3 hours, we know someone is being less than truthful. Savings in black and white are visible after the first analysis of historical bills from the last 12 months.

We also often see a lack of enforcing part warranties. Many components, like alternators or turbochargers, have a 24-month manufacturer's warranty. Services often don't inform you about this, issuing a new invoice for replacing an element that failed after 14 months. We catch such situations. In July 2024, we recovered 11,340 PLN for one client for unjustly paid repairs that should have been performed under a claim to the parts supplier.

Tires – the silent devourer of transport margins

Tire expenses are often the third largest item in a fleet budget, right after fuel and leasing. Most companies don't check tire pressure more often than once a quarter, and that's a mistake that costs 847 PLN a month with just 5 cars. Pressure that's too low by 0.4 bar raises fuel consumption by 2.8% and accelerates tread wear by 19%. At the Pomeranian Audit Center, we check if your drivers actually care about this aspect or if inspection reports are just signed 'automatically' without looking at the pressure gauge.

An analysis conducted in June 2024 showed that 63% of the vehicles we examined had improperly set suspension geometry after winter. This causes so-called tire cupping, which forces their replacement up to 14 months earlier than the manufacturer predicts. The cost of setting the alignment is about 180-250 PLN. The cost of a new set of tires for a delivery car is 1,800 - 2,400 PLN. The mathematics is simple: prevention, which we suggest in the post-audit report, pays for itself within the first 4 months of fleet operation.

The choice of the tire itself for specific routes is also important. If your cars mainly drive around the Tricity, you need a different type of rubber than a fleet running on the S6 and A1 routes to Germany. We don't sell tires, so our opinion is objective. We point to specific brands and models that in our clients' road tests lasted 14,000 kilometers more than budget solutions. Actual state, not wishful thinking – that is the foundation of our approach to optimizing operating costs.

Driving style and insurance premiums

Most fleet managers accept the amount of AC/OC premiums as a necessary evil. That's a mistake. In 2024, insurers are increasingly taking telematics data into account when pricing policies for companies. If your drivers brake sharply and exceed the speed limit on the Tricity bypass, your claims frequency will rise, and with it, insurance costs. During an audit in October 2024, we discovered that one claim caused by a driver who systematically broke the rules raised the premium for the entire fleet (14 cars) by 12.4%. This is a real cost of 9,200 PLN per year.

The Pomeranian Audit Center implements ranking systems for drivers that are not based on the 'boss's opinion' but on hard data from accelerometers. Introducing a simple bonus system for safe driving in one of Gdańsk's construction companies reduced the number of minor collisions from 7 to 1 per year. The effect? When renegotiating the insurance contract in August 2024, the agent lowered the rate by 15% due to the improved risk profile. This is a specific saving that can be demonstrated in an Excel sheet.

It's also worth checking if policies don't contain unnecessary extensions. Often companies pay for glass insurance or replacement cars in a variant that doesn't cover the delivery fleet's needs anyway (e.g., 3-day limit when the repair takes 10). We read the fine print in contracts. We eliminate duplicating services and match the scope of protection to real threats. Instead of paying for everything, you pay for what can actually save your company's financial liquidity in case of a breakdown on the road.

Safe driving is not just about ecology. It's about 15% lower insurance premiums per year.

Inefficient routes and empty runs

The final, but often most expensive point, is route planning. At the Pomeranian Audit Center, we analyze historical GPS data to check how many kilometers your cars traveled 'empty' or doubling their routes. The record-holder, an FMCG sector company, generated 18% unnecessary kilometers due to a lack of coordination between two warehouses in Gdańsk and Tczew. After optimizing the delivery schedule in May 2024, the number of vehicles needed to handle the same orders fell from 6 to 5. One less lease is about 2,800 PLN savings per month plus employee costs.

Often the problem is also a lack of considering peak hours at key junctions like Węzeł Karczemki or Matarnia. Standing in a traffic jam is not just a waste of time; it's burning 2.5 - 4 liters per hour with the engine and air conditioning on. We calculate the 'standing cost' for your fleet. We show that shifting the departure time by 30 minutes can bring 450 PLN savings in fuel per month for one vehicle. These are small steps that build a large financial result at the end of the year.

Our audits always end with a specific list of recommendations. We don't write about the 'need for optimization' but about the fact that on the Gdańsk-Elbląg route, your cars burn 1.2 liters more than they should. Actual state, not wishful thinking – that is our principle. We help implement changes and check their effects after 90 days. The numbers speak for themselves: the average return on investment in our fleet audit is only 3.5 months. If you want to stop guessing where your money is leaking, it's time for specific data.
