A cashier app and a customer app sharing one live source of data, so stock, pricing, and order status always agree on both sides.
The challenge
Cashier and customer previously saw different data, so orders could still be placed against stock that had already run out.
At peak hours, even a few seconds of lag was enough to build a queue.
Our approach
Both apps were built on a single source of truth, pushing updates live to every connected device.
The transaction path was optimised first, because that is where speed is felt most.
The system keeps accepting transactions through a brief loss of connection, then reconciles once it is back.
The outcome
The system handles more than 200 transactions per hour at peak.
Response time stays under 0.2 seconds, with data accuracy at 95%.
