Customers may be spending more, while your store keeps less.
Customers are still walking through the door, but they are choosing lower-priced alternatives, buying fewer items, and making fewer trips. From 2024 to 2025, rising operating and facility costs erased the profit from the average inside transaction and pushed it into the red.
The basket is changing—and the economics behind it are changing even faster.

Born in a gas station. Evolving with the industry.
Petrosoft began when our founder and CEO, Sergei Gorloff, worked his way from cashier to manager to owner and built the back office he could not find anywhere else.
Today, we still own and operate more than 20 convenience stores and gas stations in Western Pennsylvania. That ongoing experience keeps CStoreOffice grounded in how stores actually operate, not how a software company assumes they do. What we learn from running those stores continues to shape how CStoreOffice evolves and improves.
CStoreOffice® was born in a gas station. It continues to evolve there.



Where Profit Is Won
The best operators don’t just sell more. They keep more.
Top-performing stores move inventory faster, use labor more effectively, and need far less margin from every gallon just to cover expenses. CStoreOffice brings that same operational discipline into every store — starting with the work that has to happen every single day.
Better margins begin with what happens every day.
=
One guided path through the entire day.
Manager Daily Workflow brings the work that normally lives across paperwork, printouts, and different screens into one organized flow. It guides the manager step by step—from reviewing sales and fuel to processing purchases, balancing cash, updating inventory, and checking performance—so the day gets wrapped up faster, with less confusion and less time behind a desk.
Keep more from every gallon.
Live ATG readings, deliveries, pump sales, invoices, pricing, and margin all come together in one place, giving you the control to reduce fuel loss and keep more profit from every gallon.
Stop losing margin before products reach the shelf.
Vendor costs change. Deliveries arrive short. Dead items get reordered while best sellers run out. CStoreOffice connects ordering, receiving, inventory, and pricing so those problems surface sooner.
Open by design. Built over decades.
One cloud. Your systems. Your AI.
For more than 20 years, Petrosoft has built the digital foundation behind convenience retail, bringing together the systems, data, and workflows that run every part of the store.
The result is the Petrosoft Cloud, an open operational foundation built to work with the technology you use today and the technology you adopt next.
Open to your operation
Connect supported POS systems, ATGs, accounting platforms, ERPs, site devices, and external sales channels without rebuilding your technology stack.
Open to your ecosystem
Connect with the vendors, wholesalers, manufacturers, platforms, and partners your business depends on.
With open APIs and flexible data exchange, Petrosoft can support new connections as your business grows.
Open to your AI
Petrosoft MCP lets you connect the AI tools your business chooses directly to Petrosoft Cloud.
Because MCP is built on an open standard, you are not locked into one assistant, model, or vendor.
CStoreOffice Features
Beyond the essentials. Built for the whole operation.
More than enough to run the store. And this is only the shortlist. Explore the CStoreOffice features behind inventory, pricing, fuel, daily close, accounting, reporting, and more.

CStoreOffice FAQ
Frequently asked questions.
The questions convenience store owners and operators ask most often before switching to CStoreOffice—covering equipment compatibility, installation, data migration, day-to-day operations, accounting, and support.
Will CStoreOffice work with my current cash register and equipment?
CStoreOffice integrates with leading systems including Verifone, Gilbarco Passport, NCR, Bulloch, Nucleus, Square POS, and more. You can keep the registers, tank gauges, and accounting software you already use.
Will installation interrupt my register or store operations?
Your operations will not be affected while CStoreOffice is connected and configured.
Can Petrosoft transfer my existing price book and store data?
Once the DC Box is connected, CStoreOffice can download the price book and store data already in your cash register, saving you from sending spreadsheets or rebuilding everything manually.
What happens if my internet goes down?
Your registers continue operating, and the DC Box stores supported data locally. Once the connection returns, that data is automatically sent to CStoreOffice.
What training and ongoing support are included?
You receive guided onboarding, 24/7 support, Petrosoft University, free live monthly training, and ongoing Account Management check-ins. Help remains available long after installation is complete.
Will CStoreOffice create more work for my managers?
CStoreOffice automatically collects register data and organizes daily tasks into one guided workflow, reducing manual entry and helping managers finish their paperwork faster.
How does CStoreOffice keep my inventory accurate?
Inventory updates as items are sold, received, transferred, counted, or written off. Managers can compare expected inventory with physical counts and investigate differences down to the item.
What does CStoreOffice do that QuickBooks does not?
QuickBooks manages accounting, while CStoreOffice manages what happens inside the store, including shifts, inventory, fuel, invoices, pricing, lottery, and daily reconciliation. It prepares accurate operational data before it reaches your accounting system.
Can CStoreOffice connect with QuickBooks or my current accounting system?
CStoreOffice supports QuickBooks Desktop and Online, along with Sage, Microsoft Dynamics, MAS90, and other accounting or ERP systems.
Is CStoreOffice suitable for both single stores and multi-store operators?
Independent owners can manage one location, while larger operators can control pricing, inventory, reporting, users, and performance across every store from one account.
