When I speak to business owners about their fuel expenses, the conversation almost always starts at the bowser. Everyone wants to know how to get the cheapest price per litre. But after years of analysing fleet operations here at Fuel Card Comparison, I’ve realised something critical: the pump price is often the smallest part of the problem.
The real financial drain isn’t what you’re paying for petrol, it’s how you are paying for it.
If your business operates vehicles and you don’t currently use a dedicated fleet card, you are likely bleeding money in ways that don’t immediately show up on a profit and loss statement. Today, I want to pull back the curtain on the hidden costs of manual fuel management, and explain why adopting a fleet card strategy is one of the most effective ways to protect your margins.
Find out which fuel card suits your fleet
The Hidden Labour Cost of Manual Administration
Let’s start with the most insidious cost: your time. Or, more accurately, the time of your administrative staff.
Consider the traditional process of managing fuel expenses without a fleet card. A driver fills up, pays with their own money or a corporate credit card, and asks for a paper receipt. That receipt then sits on the dashboard, gets stuffed into a wallet, or slowly fades in the sun. At the end of the month, the driver has to collate those receipts, fill out an expense claim, and submit it to the accounts team.
Your accounts team then has to manually review each receipt, verify the amounts, enter the data into your accounting software, and process the reimbursement.
How long does that take? Even if it’s just 15 minutes per driver, per month, the costs add up rapidly. If you have ten drivers, that’s two and a half hours of pure administrative friction every single month. Over a year, that is nearly a full working week lost to data entry.
When you implement a fleet card, this entire process vanishes. All transactions are consolidated into a single, ATO-compliant monthly invoice. The best fleet card options like the Shell Card, FleetCard Classic, and WEX Motorpass integrate directly with Xero and MYOB.The data feeds in automatically, perfectly categorised. The administrative saving alone often outweighs the monthly card fees several times over.
The Cost of Missed GST and Fuel Tax Credits
Following on from manual administration is the very real cost of human error. When you rely on paper receipts, things go missing. It is a simple fact of fleet management.
When a receipt goes missing, your business cannot legally claim the GST back on that purchase. If a driver loses a receipt for a $150 fill-up, that is roughly $13.60 in GST that your business simply absorbs. Multiply that by several lost receipts across multiple drivers over a year, and you are leaving hundreds, if not thousands, of dollars on the table.
Furthermore, if your business is eligible for Fuel Tax Credits (FTC), accurate record-keeping is non-negotiable. The ATO requires precise documentation of how much fuel was purchased and what it was used for. Trying to calculate FTC entitlements from a shoebox of faded receipts is a nightmare, and often results in businesses under-claiming their entitlements just to be safe.
A fleet card solves this instantly. Because the monthly statements are ATO-compliant, you never have to worry about a lost receipt again. Every drop of fuel is tracked, recorded, and ready for your accountant to claim every cent you are legally owed.
The Silent Drain of Fuel Theft and Misuse
This is the cost that no business owner wants to talk about, but it is one of the primary reasons I advocate so strongly for a fleet card strategy.
When you give an employee a standard corporate credit card, you are handing them an open line of credit. Yes, you might have a strict policy that the card is only for fuel, but enforcing that policy is incredibly difficult. An employee can easily buy a pie, a coffee, or a magazine alongside their fuel, and unless your accounts team scrutinises every single line item on every single receipt, those purchases will slip through.
Worse still is the risk of outright fuel theft such as an employee filling up their personal vehicle on the company dime.
A dedicated fleet card provides unparalleled security and control. You can restrict purchases solely to fuel and oil, completely blocking the ability to buy shop items. You can set individual purchasing limits, and tie cards to a specific vehicle registration. The BP Plus card even allows you to prompt drivers to enter their odometer readings at the point of sale, making it incredibly difficult to mask unauthorised fill-ups.
If a card is lost, or if you notice suspicious activity, a fleet card can be blocked instantly via an online portal or app. This level of control is impossible to achieve with cash or standard credit cards.
The Cost of Unpredictable Cash Flow
In business, managing cash flow is just as critical as managing profitability. When you reimburse employees for fuel, or pay for it daily out of your operating account, your cash flow is at the mercy of your drivers’ schedules.
If three drivers all decide to fill up their trucks on a Tuesday, that is a significant chunk of cash leaving your account on a single day. This unpredictability makes it difficult to forecast and manage your working capital.
A fleet card provides vital breathing room by consolidating your fuel purchases into a predictable billing cycle with an interest-free credit period. Instead of cash trickling out every day, you pay one consolidated bill at the end of the cycle.
The Shell Card offers up to 14 days to repay your purchases, while the FleetCard Classic and BP Plus offer impressive interest-free credit periods of up to 51 days. This allows you to align your fuel expenses with your incoming revenue, keeping cash in your business for longer.

Shell Card: Best for Small and New Businesses
The Shell Card is the fleet card I recommend most often to businesses that are just getting started with fleet management, and it’s easy to see why. At the time of writing, new customers can access a 7c/L promotional discount for the first six months using the promo code CPM7FOR6, with the monthly card fee waived entirely during that period. After the promo, the ongoing fixed discount of 2c/L on unleaded and 4c/L on premium fuels still represents solid savings, particularly for businesses that regularly use premium diesel.
What I find particularly compelling about the Shell Card is the Smart Alerts system built into the Shell Card Portal. Fleet managers can set custom thresholds on individual cards and receive email notifications within minutes of a suspicious transaction, a proactive security feature that most cards don’t match. Add in Xero and MYOB integration, PIN protection, and the ability to restrict purchases by fuel type, and you have a highly capable fleet card at a very low cost of entry.

FleetCard Classic: Best for Businesses Needing Broad Coverage
If your drivers travel across diverse routes and can’t guarantee they’ll always be near a specific brand, the FleetCard Classic is the most versatile fleet card on the market. Accepted at over 6,100 fuel stations — roughly 90% of sites nationally — it covers BP, Shell, 7-Eleven, Ampol, Mobil, and many others. The introductory 6c/L discount at Shell and Reddy Express for the first six months is a strong opening offer, and the ongoing 3c/L at Shell remains competitive.
What sets FleetCard Classic apart from a pure fuel card is its non-fuel merchant network. With over 6,000 merchants covering servicing, tyres, windscreens, smash repairs, and vehicle batteries, it effectively becomes a single account for all vehicle-related expenses. The Xero integration and 51-day interest-free credit period make it a particularly strong fit for SMEs running between 3 and 20 vehicles.
Save up to 6c per litre on fuel for your business
WEX Motorpass: Best for Regional Fleets
For businesses whose vehicles travel unpredictable routes across metro and regional Australia, the WEX Motorpass is the fleet card I’d put at the top of the shortlist. Its network of over 6,500 service stations includes major brands and hundreds of independent operators, making it the most reliable option for drivers who can’t always count on finding a specific brand.
The reporting capability is where WEX truly differentiates itself. ATO-compliant statements capture transaction-level detail including vehicle IDs, driver IDs, and odometer readings — giving finance teams the data they need to calculate true cost-per-kilometre and identify inefficiencies across the fleet. At the time of writing, new customers can have the $5.99 monthly card fee waived for six months using the promo code ZEROFEE26.
$0 card fees
BP Plus: Best for Qantas Points Earners and EV-Ready Fleets
The BP Plus card is a strong choice for business owners who want their fleet spend to work harder through loyalty rewards. At the time of writing, new customers earn 3x Qantas Points on eligible fuel for the first six months, plus up to 100,000 bonus Qantas Points, a compelling offer for frequent business travellers.
Beyond rewards, BP Plus provides access to the BP Specialist Discount Network, which includes Beaurepaires, Bob Jane T-Marts, Bridgestone, O’Brien Autoglass, and Ultra Tune. For businesses beginning to transition to electric vehicles, the card’s integration with the bp pulse charging network covering over 250 rapid and ultrafast charge points nationally, makes it one of the most forward-thinking fleet card options available in Australia today.
Save up to 2c/l.
AmpolCard: Best for Transport, Logistics, and Everyday Rewards
For businesses that predominantly operate near Ampol stations, particularly those in transport and logistics — the AmpolCard offers one of the most attractive promotional discount structures on the market. At the time of writing, new customers can choose between 8c/L for 10 months or 6c/L for 18 months, depending on their preference for depth versus duration of savings.
The Everyday Rewards integration is a genuine differentiator. By linking your Everyday Rewards card to your AmpolCard account, every litre of fuel earns points that can be redeemed at Woolworths or converted to Qantas Points. For businesses spending heavily on fuel, this loyalty benefit accumulates quickly. The card also integrates with Xero and MYOB, and with access to over 1,700 Ampol sites nationally, it covers a substantial portion of the Australian network.
200+ Ampol National Truck Stops
Don’t let the hidden costs of manual fuel management eat into your margins any longer. Review your processes, compare the options above, and implement a fleet card strategy that protects your business.
