For many Australian marinas the fuel wharf is the busiest corner of the property: weekend fishing boats topping up at dawn, cruisers taking on hundreds of litres for the trip north, and the local commercial operators who buy week in, week out. It is high-turnover revenue held in a couple of big tanks, and it deserves better than a standalone terminal and a paper log. Fuel management software ties the tank, the sale, and the customer together so the wharf earns cleanly.
This guide covers what fuel wharf management should handle and what to look for.
- Fuel is high-turnover revenue that leaks when stock and sales live apart.
- Every sale should draw against tank stock so dips match the books.
- Sales tied to boats and accounts build the full customer picture.
- Regulars and commercial operators want fuel on account, not cash each visit.
- GST on fuel sales should flow into the same records as the rest of the marina.
#Stock and sales in one ledger
The discipline is simple: deliveries in, sales out, and the tank's dip should match the difference. When every sale is recorded against the tank in the same system, a mismatch surfaces within days and gets investigated while the trail is warm. Kept on separate systems, the same mismatch hides until stocktake and becomes an unexplained write-off.
#Sales tied to boats and accounts
Recording who bought the fuel and for which boat turns the wharf into part of the customer relationship. Berth holders and regulars can run fuel on account and settle it through their normal billing with GST, and the marina sees each customer's full value: berth, fuel, service, storage, one picture, as part of the wider marina system.
#The commercial trade
Charter operators, dive boats, and workboats buy serious volumes on schedule, and they expect trade terms: fuel on account, monthly invoicing, and clean paperwork. Handling that well is sticky recurring revenue for the wharf, and it only works when accounts, pricing, and invoicing live in one system.
