What it means
A fleet card looks like a normal payment card but behaves quite differently at the point of sale. It can be locked to fuel and vehicle categories only, capped by daily or weekly limits, and tied to a specific vehicle or driver, so a card used for groceries is simply declined.
The real value is the data rather than the plastic. Each transaction records the odometer reading, driver identity, fuel grade and volume, which lets a fleet manager calculate cost per mile and spot the vehicle whose consumption suddenly worsens.
Cards also change the finance team's workload. Instead of processing hundreds of small expense claims and chasing missing receipts, accounts payable receives one itemised statement that can be coded straight into the general ledger.
Providers typically earn from a monthly card fee, an interchange share, and sometimes a small transaction charge, while offering a negotiated discount per unit of fuel at participating sites. Whether the arrangement pays for itself depends on the volume of fuel bought and how tightly the network of accepting stations fits the routes actually driven.
The usual nuance is acceptance. A card with a deep discount but a thin station network can push drivers into detours that cost more in time and mileage than the discount saves, so coverage should be checked against real routes before signing.
In practice
Real-world examples.
Example
A regional plumbing firm issues one fleet card per van with a daily cap of $120 and a fuel-only restriction. When a card is used for a $90 purchase at a hardware store, the transaction is declined at the till and the office is alerted the same afternoon.
Example
A food distributor uses odometer data captured at the pump to calculate litres per 100 kilometres for each truck. Two vehicles show consumption 18% worse than the rest of the fleet, and a service check finds a fuel injector fault on both.
Example
A facilities management company replaces monthly mileage reimbursement claims with fleet cards for its 60 field engineers. Month-end close moves two days earlier because finance no longer waits on individual expense submissions.
Formula
Calculation
Net annual benefit = (Fuel volume x Discount per unit) + Recovered misuse - Card fees.
A distribution business runs 40 vans, each using about 250 litres of fuel a month at $1.30 a litre.
Annual fuel volume = 40 vans x 250 litres x 12 months = 120,000 litres.
Annual fuel cost = 120,000 x $1.30 = $156,000.
Negotiated discount of $0.08 a litre = 120,000 x $0.08 = $9,600 a year.
Card fees of $3 per vehicle a month = 40 x $3 x 12 = $1,440 a year.
Controls and reporting cut unauthorised or wasteful spending by 2% of fuel cost = $156,000 x 2% = $3,120.
Net annual benefit = $9,600 + $3,120 - $1,440 = $11,280, or about 7.2% of the fuel bill.Case study
Seen in the real world.
Redgate Couriers is an illustrative company invented for this entry. It ran 40 vans on a mix of personal credit cards and cash advances, and the finance manager estimated that reconciling fuel spending consumed three full days a month.
After moving to fleet cards, Redgate captured a discount of $0.08 a litre on 120,000 litres, worth $9,600 a year, and paid $1,440 in card fees. The controls also stopped a pattern of weekend fills on vehicles that were parked at the depot, which had been running at roughly 2% of the fuel bill, or $3,120 a year.
Redgate's illustrative net benefit was $11,280 a year before counting the reclaimed administrative time. The finance manager's own summary was that the discount paid for the programme and the data paid for everything else.
Watch out
Common mistakes.
- Choosing a provider on the headline discount alone. A larger discount at a station network that does not match your routes costs more in detour mileage than it saves at the pump.
- Issuing cards without setting category, value and time restrictions. An unrestricted fleet card is just a company credit card with extra fees attached.
- Ignoring the transaction data once the cards are live. The reporting is where most of the value sits, and it does nothing if nobody reviews the exception reports.
Questions
People also ask.
Do fleet cards work like credit cards?
Some settle monthly like a credit account and others are prepaid or debit based, so it is worth confirming the settlement terms before assuming you get a float.
Can drivers still use them for personal fuel?
Only if the controls allow it, since cards can be locked to specific vehicles, product categories, times of day and value limits.
Are fleet cards worth it for a very small fleet?
Below about five vehicles the discount rarely covers the fees, but the record keeping and tax substantiation benefits can still justify them.
