Best Petroleum Marketer Software in 2026: One Marketer's March, Four Ways the Money Came In
A fuel jobber has one problem: the load. A petroleum marketer has four, because the money comes in four different ways and they all have to land in the same profit and loss at the end of the month. Below is one marketer's March, line by line, and what it takes for a system to close it in a day instead of a week. We build one of these systems, called FastDragon, and I have said where it stops as well as where it starts.
The marketer in this example
Four point one million gallons a year. Nine dealers supplied off the rack. Two stations owned by the company and run by commissioned agents. One store the company runs itself. Two more sites where the company owns the dirt and leases to a dealer. One bookkeeper, one dispatcher, one owner who reads the P&L on the fifth. That shape is common enough that I could be describing two hundred companies, and the software decision they all face is the same one.
March, four ways
| Line of business | Gross margin | How it got there | Where it usually lives |
|---|---|---|---|
| Wholesale to nine dealers | $18,860 | 205,000 gal at 9.2¢ | Jobber software |
| Two commissioned-agent stations | $28,910 | 118,000 gal at 24.5¢ after commission | A spreadsheet, usually |
| One company store, fuel | $18,910 | 61,000 gal at 31.0¢ | Store back office |
| One company store, inside sales | $29,140 | $94,000 of sales at 31.0% | Store back office |
| Rent on two leased sites | $9,600 | Two sites at $4,800 | QuickBooks, or a folder |
$105,420 of gross margin on 384,000 gallons and a store. Look at the cents per gallon and the store gallon at 31 cents reads like three times the business the dealer gallon at 9.2 cents is. The gap is a good deal smaller than that, and every owner who has run a store knows why. Behind that 31 cents sits rent, taxes on the dirt, canopy lights, a cooler that fails in July, credit card fees, and payroll for people who work nights. The dealer gallon has a truck behind it and nothing else.
A marketer who cannot see the cost side by line of business is guessing about which channel to grow. Showing him the cost side by line of business is the real job of petroleum marketer software, and it is a harder job than turning a load into an invoice.
Look at the last column
Wholesale in the jobber system. Agents in a spreadsheet. The store in a store back office. Rent in QuickBooks. Nobody sat down and chose four systems. The business grew one line at a time and each new line landed wherever there was room that year.
The bill for that arrives at month end. The bookkeeper exports the store, keys a summary journal for the agents, remembers the rent, and then spends two days finding out why the fuel inventory in the wholesale system does not match the gallons the store says it sold. The owner gets his P&L on the twelfth instead of the fifth, and by then the month is half gone and there is nothing to do about what it says.
The four seams where systems break
When a marketer tells me his software is fine except for month end, the problem is nearly always at one of these four joints. Put each one in front of every vendor and make them show you.
| Seam | What has to be captured | What good looks like |
|---|---|---|
| Agent settlement | Fuel sold, card receipts, rent owed, commission earned, all for one station for one day | The day settles itself and lands in the ledger as a balanced entry |
| The store day | Fuel gallons and dollars, inside sales by department, lottery, shrink, deposits | The fuel side of the store day posts against the same inventory the wholesale side moved |
| Intercompany rent | The property company bills the operating company for the site | Both sides post, and the consolidated P&L eliminates it instead of counting it twice |
| Entity separation | Operating company, property LLC, trucking entity | Every transaction carries its entity from the start, so each set of books stands on its own |
Agent settlement is the one most systems skip. A commissioned agent runs the station and you keep the fuel. Every day there are gallons sold, card money coming in through the network, rent owed to you, and commission owed to him, and the four numbers have to settle against each other. See what is a commissioned agent.
The store day has to post against the same fuel inventory the wholesale side moved. If the store is a separate product, the gallons get counted in two places and reconciled by hand. See fuel and inside sales reconciliation.
Intercompany rent is where a lot of marketers quietly overstate themselves. The property LLC bills the operating company. Both sides have to post and the consolidated statement has to eliminate it. See real estate for fuel operators.
Entity separation has to start at the transaction, not at the report. A system that keeps one set of books and sorts entities out at the end will disagree with your tax return. See multi-entity accounting for petroleum.
Take your own March to the demo
Skip the feature list. Print one real month out of your current systems, all four pieces of it, and ask every vendor to close it in front of you. Specifically:
- Key one transport load split across three dealers, with freight and two states of tax. Count the entries.
- Settle one agent station for one day. Watch where the commission, the rent and the card money land.
- Post one store day, then show me the fuel inventory afterwards from the wholesale side.
- Bill the rent from the property company to the operating company, then show me the consolidated P&L with it eliminated.
- Show me gross margin by line of business for the month, with the site costs underneath.
- Now show me the same five screens on a phone, because that is where the owner reads them.
A vendor who can do all six on your data in one sitting has earned a second meeting. The full printable version is in how to choose fuel jobber software.
The vendors worth a call
- PDI Enterprise Wholesale. More than 250 petroleum marketers run it. Order processing, fuel accounting, cardlock, equipment, a customer portal, and motor fuel tax through an Avalara partnership. Built and priced for large multi-state operators with staff to match.
- ADD Energy E3. A family firm in Flanders, New Jersey since 1973, covering propane, heating oil, wholesale and stores from one platform with the Raven handheld on the truck. The books sit on Microsoft Dynamics, so budget a second licence and a talk with your accountant.
- RR Fuel. Red River Software, Post Falls, Idaho, over forty years, 1,200 customers. Strongest around co-ops, propane and consumer route delivery, with DTN price import and EDI tax files on the wholesale side. Stores are separate products.
- COMPAS Commander. AIMS, fifty-plus years in financial software, accounting first. Tank-level inventory and excise reporting. Bought Petro-Data on April 1, 2026.
- iRely Petroleum. A single ERP spanning fuel, lubricants, propane, stores and agriculture, aimed at the large end of the market.
- Series2K. Store back office first, one site up past a thousand. I spent over a decade there and still send operators that way when the stores carry the company and the wholesale is the sideline.
- FastDragon. Ours. Below.

Where FastDragon fits
FastDragon was built around the four seams. An agent station settles for a day in one screen, with the gallons, the card money, the rent and the commission balancing against each other. A store day posts against the same fuel inventory the wholesale side moved, so the gallons get counted once. Rent from the property company to the operating company posts on both sides and drops out of the consolidated statement. Every transaction carries its entity from the moment it is keyed. March closes out of one set of numbers, and the owner opens gross margin by line of business with the site costs sitting underneath it. An owner who wants his accountant to stay in QuickBooks can post there instead.
Where it stops: a fifth line of business we do not cover, the residential heating route. Degree days, K-factors, prepaid contracts and propane tank rental are Red River and ADD Systems territory. If that route is on your March, put them on the list first. Screens are on the Fuel Jobber page, bands on pricing.
Questions people ask
What is petroleum marketer software?
The back office for a company that buys fuel at wholesale and sells it on through more than one channel. It prices off the rack, turns each load into invoices, figures motor fuel tax per gallon per state, settles the supplier, bills dealers, settles commissioned agents, and posts the whole thing to a ledger. Petroleum marketer is a broader term than fuel jobber, and the breadth is exactly what makes the software choice hard.
What is the best petroleum marketer software in 2026?
It depends on how many channels your money comes in through. For a large multi-state marketer with accounting and IT staff, PDI Enterprise Wholesale. For a marketer built around consumer route delivery, RR Fuel or ADD Energy E3. For a small or mid-size marketer whose money comes in through dealers, agents, stores and property at once, FastDragon and COMPAS Commander from AIMS are sized to that. For an operator whose business is mostly stores, Series2K.
Why do marketers end up with four systems?
Because each channel arrived separately. The wholesale system was bought first. The agent stations came later and went onto a spreadsheet. A store got bought and came with its own back office. The property went into QuickBooks because the accountant asked for it. Nobody decided on four systems. The business grew and each new line landed wherever there was room.
Should the books live in the software or in QuickBooks?
Either works as long as one of them is the source. Trouble starts when fuel lives in one system, agents live in a spreadsheet, and QuickBooks holds a summary journal typed in once a month, because then no two of the three agree and nobody can say which is right. FastDragon keeps a full ledger and also posts to QuickBooks for owners who want their accountant to stay where they are.
How long does a conversion take?
Six weeks is normal for a small or mid-size marketer, and a couple of months when several entities, a lot of history, or store data come across. The time goes to data: customers and price formulas, supply contracts, tax setup per state, open receivables, leases. Ask whose staff does that work and get the live date in writing before you sign.
