The operating system for energy retail

One platform for fuel,
shop, people and books.

GSM puts OMCs and their dealers on a single operating system โ€” fuel supply, convenience retail, POS, payroll and full double-entry accounting โ€” with live visibility from tank dip to balance sheet.

The problem

Service stations run on systems
no one can see into.

Phone-in fuel orders, standalone POS, spreadsheets for the books โ€” each site works in isolation, and the network sees the result long after the fact.

๐Ÿ“ž
Reactive fuel ordering

Orders arrive by phone and email. Replenishment is guesswork โ€” stock-outs and emergency drops are routine.

โš ๏ธ
Supply leakage

Nothing proves every litre sold came from your terminals. Cross-buying quietly erodes volume and brand.

๐Ÿ’ณ
Unmanaged credit

Dealer and fleet credit runs on goodwill. Limits live in spreadsheets โ€” not at the point of sale.

๐Ÿงฎ
Fragmented back office

POS, payroll, inventory and the books never reconcile. Variance hides in the gaps between systems.

Supply integrity

Every litre accounted for.

Daily wet-stock reconciliation squares what went into the tank with what went through the pumps โ€” automatically.

๐Ÿšš
Litres in

OMC deliveries, docketed at the tank with pre- and post-drop dip readings.

โ›ฝ
Litres out

Dispenser totalisers reconciled against POS fuel sales, shift by shift.

โœ…
Litres left

ATG stock closes the loop. Unexplained loss or gain is flagged every single day.

If the fuel didn't come from you, the arithmetic says so โ€” supply integrity enforced by daily reconciliation, not yearly audits.

The platform

Everything a station runs on.
Nothing bolted together.

โ›ฝ
Fuel Supply & Ordering

Low-stock alerts raise draft orders per tank; every dealer PO lands in one queue and the delivery docket books litres, weighted cost and the ledger in one transaction.

๐Ÿ›ข๏ธ
Tanks & Wet-Stock

ATG dip readings around the clock, daily variance between deliveries, dispenser totalisers and measured stock โ€” unexplained loss or gain is flagged every day.

๐Ÿ”Œ
Hardware Gateway

Connect ATGs and dispensers through a heartbeat-monitored gateway โ€” or key readings manually on older forecourts. Same validations, same reports, either way.

๐Ÿงพ
Point of Sale

Fuel and shop in one basket, twelve payment modes each mapped to its own GL account, and a cash ledger that must balance every shift.

๐Ÿช
C-Store Inventory

One catalogue network-wide, weighted-average cost, reorder points, stocktakes and wastage per product per station โ€” with supplier bills posted on receipt.

๐Ÿ’ณ
Credit Accounts

Fleet, corporate and local trade accounts with limits enforced at the POS โ€” past the threshold the account suspends and the sale is refused, automatically.

Accounting

Books that write themselves.

Every operational event posts its own balanced journal โ€” fuel deliveries, POS sales, approved expenses, pay runs, supplier payments. The ledger is a by-product of running the site, not a month-end project.
