Most fuel businesses run on a few numbers everyone trusts and a lot of gut feel. The trouble is that the trusted numbers are usually averages, and an average is the easiest place for a problem to hide. Your company margin can look fine while one route, one product, or a handful of customers quietly bleeds. The fix is not a flashier dashboard. It is the right few numbers, broken down far enough to act on, looked at often enough to catch a problem while it is still small. Here are the ones that actually tell you how you are doing.
1. Margin per gallon, split by customer, route, and product
Your blended margin is an average, and a loss hides in an average better than anywhere else. One route running two cents under the rest vanishes in the company total. Break margin down by customer, by route, and by fuel grade, and the weak spots show up the same day. Most of them are a quick fix once you can see them: a price move, a contract review, a route change. The number you manage by should be the broken-down one, not the company average.
2. Delivered cost per gallon (cost to serve)
It costs real money to put fuel in a tank, and the smallest drops cost the most per gallon. A half-empty bobtail driving 30 miles to top off one tank can erase the margin on that delivery. Track what it actually costs to serve each stop instead of an overall average, and you can see which accounts are profitable to deliver to and which need a bigger minimum, a different day, or a route change. This is where routing turns straight into margin.
3. Days sales outstanding (DSO)
DSO is how long it takes to get paid. Every day a dollar sits in receivables is a dollar you are lending a customer for free, and a slice of it never comes back. Watch DSO and AR aging together. A rising DSO is an early warning, usually weeks before a balance turns into a write-off, which is plenty of time to tighten terms or hold a delivery if you see it.
4. Truck and route utilization
Your trucks make money when they are pumping, not when they are driving. Gallons per stop, stops per route, pump time versus drive time. Low utilization is margin you are paying for in fuel, labor, and equipment without the volume to show for it. You do not need a perfect number here, just a way to spot the route that is burning a day to move half a load.
5. Forecast accuracy
For keep-full and automatic delivery, the forecast is the business. A runout means an emergency fill and an angry customer. An early top-off means a wasted trip. Both are expensive, and both come from a forecast that drifted. Track how close your predicted gallons land to the actual gallons delivered, the way heating oil shops watch a K-factor, and tighten the accounts that miss. Good forecasting is the difference between a planned route and a scramble.
6. Shrink trend
Shrink earns its own place on the daily list. A small loss from temperature and handling is normal. What matters is your baseline and whether it moves. A steady number is physics. A rising one is a meter, a leak, or theft, and it is one of the quietest places margin leaks away. You only see the change if you reconcile often.
Look at them often, not once a year
The whole point of these numbers is timing. A small margin slip, a creeping DSO, a route that went unprofitable last month: caught early, each is a quick correction. Found at year-end, each is a loss you already took. You do not need more numbers. You need the right few, broken down enough to mean something, in front of you while you can still act on them. FastDragon pulls your buys, deliveries, inventory, and invoices into one place, so the numbers that matter are there each morning instead of locked in a spreadsheet you build after the month is already over.
Common questions
Is my accountant not already tracking this?
Your books tell you what happened, accurately, after the period closes. These operational numbers are about catching a problem this week, not explaining it next month. Both jobs matter, but only one of them stops a loss before it lands. Your accountant is the rear-view mirror; this is the windshield.
We are small. Do we need all these metrics?
You need the breakdown more than the volume. A small shop with three routes can usually see at a glance which one is dragging once margin is split out by route. None of this requires a big operation. It requires your data sitting in one place so the breakdown is quick to pull.
What if my data lives in five different places?
That is the real obstacle for most shops, and it is exactly why averages win by default. Building a true per-route margin from a fuel system, a billing system, and a spreadsheet is too much work to do every week, so nobody does. The payoff shows up when buys, deliveries, and invoices share one system and the breakdown is a click instead of an afternoon.
