Most operators can quote yesterday’s fuel volume to the litre. Far fewer could say whether their site margin moved up or down this quarter. Revenue is the number you watch; profit is the number that pays you, and the gap between them is where money quietly leaks away. Most sites are leaking in three or four of the eight places below right now, and not one of them requires selling a single extra litre to fix.
1. Merchant fees nobody has reviewed since signup
Card acceptance costs were set the day the terminal was installed, often years ago, and card share of sales has climbed every year since. A typical independent site puts around $500,000 a month through the terminal. At a blended fee rate of 0.45 per cent that is $2,250 a month in fees; sites on well-negotiated arrangements are paying closer to 0.30 per cent, or $1,500 a month on the same turnover. That is a $9,000 a year difference for the same tap of the same cards, and we have seen statements where the gap is wider again.
This leak now has a deadline attached. From 1 October 2026 the Reserve Bank’s reforms ban surcharging on eftpos, Visa and Mastercard, debit and credit alike. Surcharging disappears as a recovery mechanism, which makes the underlying merchant rate the whole game. The same reforms cut interchange caps from the same date, so there is genuine room for rates to move; the savings will flow to merchants who ask, not to those who wait.
This week: pull your last three merchant statements and work out your effective rate: total fees divided by total card turnover. Not the headline rate you were quoted, the rate you actually paid. Or skip the maths: ServoPro members can send us a statement and we will do the review for you.
2. Electricity contracts that rolled onto default rates
Energy contracts expire quietly. The site keeps running, the bill keeps arriving, someone keeps paying it, and nobody notices the contract lapsed onto a standing offer months ago. The bill does not announce this; it just gets bigger.
There is a second version of this leak that catches careful operators. One site we know of switched suppliers on a broker’s recommendation and ended up paying more than before, because nobody checked the new rates against the old ones after the switch went live. The lesson is not that switching is bad. It is that a switch is only a saving when the rate on the bill matches the rate on the quote, and the only way to know is to check.
This week: find your contract end date and put the rate you are paying today next to the rate you agreed to. Two numbers, one line each. Members can also send us a recent bill and our team will run the comparison and check the market for a better rate.
3. A fuel pricing strategy running on autopilot
Every site has a pricing strategy, even if nobody has written it down: match the competitor across the road, sit a cent under the nearest major, hold margin on premium grades, chase volume on diesel. The leak is not the strategy itself. It is running last year’s strategy in this year’s market without ever reviewing whether it still earns its keep.
Markets move. A competitor changes hands, a U-GO opens nearby, a major starts pricing a grade differently, and the settings that made sense six months ago quietly become margin given away or volume lost. A site pumping 300,000 litres a month has $3,000 a month riding on every cent per litre of its settings, which makes the pricing strategy one of the most valuable things on the site to review and one of the least reviewed.
This week: write down your current pricing approach in two or three lines, grade by grade if it differs, then ask whether each setting is still a deliberate decision. If nobody can say why a setting exists, that is the review telling you something.
4. Shop promotions nobody turned off
The two-for deal went up for a supplier campaign. The campaign ended. The shelf ticket stayed. Every basket that takes the deal is now giving away shop margin for a promotion that no longer has a reason to exist.
Shop margin is the hardest-won margin on the site, and it erodes in small, silent increments: a forgotten multi-buy here, a stale price board there. None of them are large enough to notice on their own, which is exactly why they survive.
This week: walk the store with the promotions list in hand and kill anything that does not have a current reason to exist. If it is not on the list but it is on the shelf, it goes.
5. Supplier price creep on shop stock
Cost prices climbed all year. Shelf prices did not. Each supplier rise was small enough to ignore, a few cents on a carton, a per cent on an invoice line, and together they quietly compressed shop margin a point or two while everyone watched fuel.
This is the leak that suppliers rely on going unnoticed. Invoice by invoice it is trivial; across a year of deliveries it is real money coming straight out of the shop’s contribution.
This week: pull your top 20 shop lines and compare cost price now against twelve months ago. Reprice or renegotiate anything that has drifted; those 20 lines carry most of the shop.
6. Rebates and incentives never claimed
Supplier rebates, volume incentives and trade promotions exist on paper across fuel, drinks, tobacco and grocery. Plenty of them are never claimed, for the simple reason that nobody at the site owns the job of claiming them. The supplier is under no obligation to chase you to take their money.
This week: ask every major supplier rep, in writing, two questions: what rebates and incentives did this site qualify for last year, and which of them were actually paid? The gap between those two answers is money you already earned.
7. Software and services billing monthly that nobody uses
The camera platform upgrade. The loyalty add-on. The reporting tool from a POS you replaced two years ago. The music service for speakers that no longer work. Small direct debits accrete on the business account the way boxes accrete in the storeroom, and $600 a month of them is $7,200 a year.
This week: print twelve months of direct debits and justify every recurring line in one sentence. Anything that cannot be justified in one sentence gets cancelled. In our experience, almost every site that does this exercise finds at least two or three subscriptions it forgot it was paying.
8. Shrinkage treated as a cost of doing business
Drive-offs, till variance, stock loss. Every site has them, and most sites treat them as background noise rather than as a number with a trend. A site that cannot say what shrinkage cost it last month cannot say whether that figure is normal or bleeding, and a bleed you do not measure is a bleed you cannot stop.
Put one number on it: drive-offs plus till variance plus stock adjustments, monthly. The first month gives you a baseline. The third month tells you whether you have a problem. Our drive-off procedure guide covers the fuel side of this in detail.
This week: total last month’s shrinkage into a single figure, write it down, and put a recurring reminder in place to do the same every month.
Fix the biggest leak first
None of these eight require more customers, more volume or more hours behind the console. Every one of them requires the same thing: someone owning the tedious work of looking. That is why the leaks survive, because looking never feels urgent, and that is also why fixing them is the cheapest profit a site can earn this year.
Do not start with the easiest one. Start with the biggest. For most sites that is merchant fees or electricity, which is also where the help is: ServoPro members can have merchant statements, electricity bills and insurance renewals reviewed through our group buying arrangements.
