Sample project

Multi-branch POS

How we would build a POS that keeps three branches’ stock in sync — and keeps selling when the internet drops.

The challenge

A shop with three branches often runs separate cash registers and an Excel sheet updated once a week. Stock counts drift, so items run out at one branch while sitting unsold at another.

The owner only sees the day’s sales after phoning every branch at closing time, and an internet outage would stop any cloud-only till.

Our solution

We would build an offline-first POS desktop app for each counter that stores every sale locally and syncs to a central PostgreSQL database the moment the connection returns. Stock levels, prices and promotions update across all branches automatically.

The owner gets a live web dashboard with sales per branch, low-stock alerts and one-click stock transfers between branches, plus a daily summary by SMS.
