Card fees hide in the statement
They come out once a month, so every day looks better than it was. NineTenths charges them to each day’s own card sales.

Know your real margin on every gallon
See what you actually keep per gallon after card fees, freight and the cost of the fuel that is really in your tank. On your phone every morning, built from your own numbers.
No software to install. No cost. Your report in about a week.
The problem
Your posted margin isn’t what you keep
Street price minus rack price looks healthy. Then the card processor, the freight bill and the fuel you bought at yesterday’s price take their share, and the real number only shows up after the month is over.

Net margin per gallon
27.1¢ − 7.9¢ − 0.8¢ = 18.4¢ per gallon. See exactly how each number is worked out.
Card fees can take close to a third of your gross margin, and they only show up on next month’s statement.
Industry context: NACS, the convenience store trade association, puts credit card fees at 8.4¢ per gallon (2023 data) and estimates that retail expenses take a typical 35¢ gross fuel margin down to about 13¢ net. Source: NACS, “Who Makes Money Selling Gas?”
Where it goes
Three things that quietly cost you
None of them are your fault. They are just hard to see from the back office.
Tank cost and street cost drift apart
When wholesale moves, the fuel in your tank was bought at yesterday’s price. You need to know which one you are really selling.
Short deliveries go unnoticed
Checking every delivery ticket (the bill of lading) against the tank gauge by hand rarely happens. A few gallons short on each load adds up.
What you get
Every morning, one number you can trust
Built from your own sales, tank readings, fuel invoices and card statements. No spreadsheets, and no new equipment.
- Net cents per gallon, by gradeAfter card fees and freight, with yesterday compared against your own 90-day average.
- Cost in the tank against your next loadSee the gap the morning it opens, then decide whether to cut price, hold margin or time your next order.
- When to orderDays left at your current pace, so a tank never runs dry on a Friday.
- Every delivery checkedThe delivery ticket against what the gauge received, flagged the same day while the paperwork is still fresh.
Your data stays yours
One station’s data. One owner’s decision.
These are commitments, not marketing. They stay in place whoever owns or invests in NineTenths.
Only your numbers
Your margin is built from your sales, invoices, tank readings and card statements. Nothing else goes in.
Never pooled, never sold
We never combine your sales, cost or price data with any other station’s, and we never sell it.
You set every price
NineTenths shows you the numbers. Every pricing decision is yours, and nothing is ever changed at your pumps or signs.
- If any of this ever changes, we will ask you first, and you can have your data deleted.
- Your files are deleted on request, at any time, including after a free price check. We will sign a confidentiality agreement if you want one.
Why this matters: some pricing tools combine data from competing stations, and regulators and courts are looking hard at that practice. NineTenths is built the other way. Read our privacy and file-handling policy.

Questions
Good questions owners ask
Do I have to change my POS or install anything?
No. For the price check you send reports you already have. The daily app reads from the POS and tank gauge systems our first stations use, so tell us what you run.
What exactly do I need to send?
Ninety days of daily fuel sales by grade from your POS, your fuel invoices or delivery tickets, and your card processing statements for the same months. Tank gauge reports and inside sales help too, but they are optional.
What will it cost?
The price check is free. We haven’t set pricing for the daily app yet. It will be a monthly fee per site, published here before anyone signs up, and there is no obligation after the price check.
Who sees my numbers?
Only you and NineTenths. Your files are kept confidential, stored separately for each station, and never shared with another station, a supplier or a jobber. Read how we handle your files.
Will you use my data to set prices for the station down the street?
No, never. Any pricing help is learned only from your own station’s data, and you approve every change.
What happens to my files after the price check?
We keep them only as long as you are working with us. Ask and we delete them, whether or not you continue.
Why is the net margin different from what my back office shows?
Most reports subtract the rack price from the street price. NineTenths takes taxes out properly, charges card fees to the day they were earned, adds freight, and costs your fuel at what is actually in the tank, blended delivery by delivery. See the full method.
Who’s behind this?
A small Colorado software company with a petroleum engineering background. Email hello@ninetenths.pro and we’ll call you back or come by the station.
I’m a fuel jobber. Is this for my dealers?
It can be. Email hello@ninetenths.pro. Dealers keep full control of their own data, and jobbers never see it.
