The best petroleum wholesale software is the one that moves a rack change to every dealer price the same morning, turns each load into an invoice in one entry, and settles with the supplier without a spreadsheet. This guide covers what a wholesaler actually uses, the kinds of vendors, and the questions to ask before you buy. We build one of these systems, called FastDragon, so we say that up front and keep this guide fair.
What petroleum wholesale software is for
Petroleum wholesale software, also sold as wholesale fuel software or fuel wholesaler software, runs the business between the terminal and the pump. You buy at the rack on contract and spot, haul or hire the haul, and sell to dealers, resellers, commercial accounts, and your own sites. The software has to carry supply contracts, daily pricing, loads, dealer billing, fuel tax, supplier settlement, and the books, and it has to do it at wholesale volume, where a one-cent miss on a transport load is real money. If the channel is new to you, start with the side of fuel marketing the public never sees.
The features that matter
Wholesale lives on price and volume, so judge a system on the pieces that touch both:
- Rack-based pricing that runs itself. Cost moves daily. Every dealer price should recalculate from the posted rack with your markup, freight, and taxes built in, by zone where you price by zone. See rack pricing explained and zone pricing for fuel.
- Supply contracts and allocation. Contract volumes by supplier and terminal, what you have lifted against them, and a way to ration on your rules when a terminal cuts you. See fuel supply contracts and what is fuel allocation.
- BOL to invoice in one entry. The bill of lading, split across compartments and customers, should become the dealer invoices with nothing re-typed. Ask to see it on a split load.
- Dealer billing and credit. Terms, credit limits, EFT drafts, and the receivable aging by dealer. Wholesale is a credit business. See credit and collections.
- Branded and unbranded in one place. Brand reporting and dealer tank wagon pricing for the branded gallons, spot and contract buys for the rest. See DTW pricing explained and branded vs unbranded fuel.
- Fuel tax by state, filing-ready. Federal, state, and local motor fuel tax figured per gallon on every load and rolled into the returns. See motor fuel excise tax explained.
- Supplier settlement. A line-by-line check that the supplier invoiced what you lifted, at the price you were promised, with the tax and fees you expected.
- The books, by entity. A general ledger, a monthly profit and loss the owner reads, and separate books for each company if you run more than one. See multi-entity accounting.
The kinds of vendors
The market sorts into three groups:
- Legacy systems. Older platforms such as Petro-Data, often a one-time license running on an old database. Cheap to own and dated to run, and most have been bought by larger players. If yours was bought by PDI, see alternatives to PDI.
- Modern wholesale platforms. Purpose-built systems for small and mid-size wholesalers: FastDragon, ADD Systems, AIMS, Red River, and iRely.
- Enterprise ERP. PDI Enterprise Wholesale and DTN, built for multi-terminal, multi-state operators, with deep features, long implementations, and enterprise pricing.
Where you fit depends on your terminals, your dealer count, and your budget. A wholesaler lifting at two terminals for thirty dealers and one lifting at twenty terminals for four hundred should be shopping in different groups.

Questions to ask in a demo
Bring the same questions to every vendor so you can compare fairly:
- Post a rack change and show me every dealer price that moved, before I ask.
- Show me a split load turn into three dealer invoices on real data, in one entry.
- Show me contract volume by supplier and terminal, and what happens when a terminal puts me on allocation.
- How do you settle with the supplier, and how do you flag a price or tax that came in wrong?
- How do you handle branded gallons and unbranded gallons for the same dealer?
- Which states do you file in today, and can you produce a filing-ready return for mine?
- What is the all-in first-year cost: license, conversion, training, support, and per-site fees, in writing?
- Who answers the phone at month-end, and who moves my data?
A good vendor will show you, on your own numbers, and will put the answers in writing.
What it costs
Most petroleum wholesale software is quote-only. Prices run from the low five figures a year for modern platforms to six figures for enterprise ERP, plus setup and conversion. We wrote a full guide with real bands in how much does fuel software cost.
Where FastDragon fits
FastDragon is built for small and mid-size wholesalers, jobbers, petroleum marketers, and station owners. It runs rack pricing, supply contracts and allocation, BOL-to-invoice, dealer billing, fuel tax by state, supplier settlement, and the books by entity under one login. It is modular, so you switch on only the pieces you run and pay for those. Packages are sized from a single site to a multi-state operation, and we will tell you the band you land in before you spend an hour on a call. For a wholesaler who feels over-served and over-charged by the big suites, that is exactly who we built it for.
Questions people ask
What is the best petroleum wholesale software?
For a small or mid-size wholesaler, the systems worth a demo in 2026 are FastDragon, ADD Systems, AIMS, and Red River. Large multi-terminal operators usually land on PDI Enterprise Wholesale or DTN. Judge each on three things on your own data: a rack change reaching every dealer price the same morning, a BOL becoming a dealer invoice in one entry, and a supplier settlement that ties out without a spreadsheet.
Is petroleum wholesale software the same as fuel jobber software?
Mostly. A fuel jobber is a wholesaler, and the back office work is the same: rack pricing, load to invoice, fuel tax, allocation, settlement, and the books. Vendors use both labels. The wholesale label tends to mean a larger operation with supply contracts at more than one terminal and a book of dealers, and the software has to carry that scale.
What does petroleum wholesale software cost?
Almost every vendor prices by quote, because cost follows terminals, dealers, states, and modules. Modern platforms run in the low five figures a year for a small wholesaler. Enterprise ERP runs six figures with setup. Get one written first-year total from each vendor that includes conversion and training, then compare totals.
Can wholesale software handle branded and unbranded supply together?
The good ones do. Branded gallons carry brand reporting, dealer tank wagon pricing by zone, and supplier programs. Unbranded gallons move on spot and contract buys. Ask to see a dealer who takes both, priced and invoiced in one place, and ask how the system keeps the branded gallons reported to the supplier.
How long does it take to switch petroleum wholesale software?
A few weeks to a few months for a small or mid-size wholesaler. The work is data conversion: dealers and their price formulas, supply contracts, tax setups for each state, open receivables, and history. Ask each vendor who does the conversion, their staff or your office, and get a live date in writing.
