The U.S. convenience industry is splitting in two. According to the 2026 NACS/NielsenIQ store count, companies with 10 or fewer stores own about 63% of locations, while chains with 500 or more stores now operate 33,810 stores, or 22.2%. Total store count slipped by 280, even as fuel-selling stores reached an eight-year high.
If you run 15, 40 or 120 stores, you’re in the middle: too big to manage on spreadsheets and phone calls, and competing with giants that have huge IT budgets. Growth, often through acquisitions, is how mid-size chains stay competitive. But every store you add brings a new set of systems, habits and blind spots.
Petrosoft operates 22 gas stations of its own, so we understand what it takes to run a chain on one system. Here’s how CStoreOffice®, SmartPOS, Retail360, QwickServe and Eagle Eye help mid-size chains grow without losing control.
Standardize from day one
An acquired store usually arrives with its own POS, its own price book and its own way of closing a shift. Until it’s on your system, you’re managing it blind.
How Petrosoft helps: CStoreOffice® gives every store the same back office: one centralized price book, one set of cash and shift controls and one full accounting ledger. SmartPOS puts the same register at every counter, so new stores report like old ones.
Buy like a big chain
NACS reports that in-store sales hit a record $341.2 billion in 2025, up 1.7%, but card fees also hit a record $21.3 billion and operating expenses rose 4.2%. Mid-size chains win on margin by purchasing and pricing with the discipline of a larger company.
How Petrosoft helps: Wholesale EDI purchasing in CStoreOffice® brings vendor invoices in electronically and checks them against your costs across every location, so you catch overcharges and price-book errors at scale.
Protect what you just bought
The NRF and Loss Prevention Research Council found 40% of retailers saw more organized retail crime in 2025, and 50% saw more repeat offenders. New stores, with new staff and new routines, are often the easiest targets.
How Petrosoft helps: Eagle Eye links video to SmartPOS transactions at every site, so your loss-prevention team can watch exceptions at newly acquired stores closely during the transition.
Upgrade the newly acquired food program
Foodservice now makes up 28.5% of in-store sales and 38.9% of in-store gross profit, according to NACS. Many acquired stores have underdeveloped food programs, which makes them one of the fastest ways to lift a new location’s profit.
How Petrosoft helps: QwickServe self-order kiosks and kitchen displays give every store a consistent food ordering experience, with sales flowing straight into CStoreOffice®.
The acquisition integration checklist
- Move the acquired store onto CStoreOffice® and SmartPOS as early as possible.
- Load your centralized price book and promotions on day one.
- Turn on EDI purchasing so vendor costs match the rest of the chain.
- Add Eagle Eye and watch voids, refunds and cash closely for the first 90 days.
- Roll out QwickServe where food sales are weak.
- Give district managers Retail360 so new stores get attention between visits.
Frequently asked questions
How many convenience stores do large chains own?
According to the 2026 NACS/NielsenIQ count, chains with 500 or more stores operate 33,810 stores, or 22.2% of U.S. convenience stores. Companies with 10 or fewer stores own about 63%.
What’s the first step after acquiring a convenience store?
Get it onto the same back office and POS as the rest of your chain. Standard systems are the fastest way to see how the store is really performing. CStoreOffice® and SmartPOS are built for that.
How can mid-size chains compete with large c-store chains?
Run with the discipline of a larger company: centralized pricing, EDI purchasing, strong loss prevention and a solid food program. Petrosoft’s connected tools give mid-size chains those capabilities without a giant IT team.
How do I control pricing across many stores?
Use a centralized price book. CStoreOffice® lets you set and push prices and promotions to every store’s SmartPOS at once.
Does Petrosoft use its own software to run stores?
Yes. Petrosoft operates 22 gas stations and runs CStoreOffice®, SmartPOS, Retail360, QwickServe and Eagle Eye in them.
