CASE STUDY

LPG Gas & Cylinder Module — Adding a New Industry to HisabMate

Gas is sold in kilograms, but cylinders go out and come back. A new module tracks both, built in about two days without touching existing sale logic.

Client: An LPG business using HisabMate.pk
Sector: LPG gas distribution
Status: Delivered and live

An LPG dealer needed HisabMate.pk to understand their trade. The owner must know which customer holds how many empty cylinders, while gas itself is billed by weight.

LPG sale at the till: gas billed by kg, cylinders filled out and empties back

Customer cylinder ledger: how many cylinders each customer holds

Screens from the live app, shown with sample data.

THE PROBLEM

What was getting in the way?

Gas is billed in kg; cylinders are assets that move between shop and customer.
Empty cylinders held by customers were not visible on bills or statements.
The change could not risk the sale functions other businesses already rely on.

WHAT WAS BUILT

The delivered solution

Cylinder panel at the till and a cylinder ledger for each customer.
Cylinders printed on the bill and the customer statement.
Three new reports in kg, a stock check and Urdu labels.
Offline-safe retry queue for cylinder entries.

HOW

How it was delivered

Three phases — database, app, reports — in about two days. One new table and four database functions carry the cylinder logic, and the existing sale functions were left unchanged, so nothing else could break. Each phase was tested in a real browser before release.
