Step-by-step view of how we moved from the brief to the outcome.
Step 01Challenge
The chain ran three disconnected systems: customer app (outsourced to India), POS (vendor end-of-life), back-office (Excel + Google Sheets). Data didn't reconcile across channels, no unified loyalty programme existed, and every promotion had to be entered manually into each outlet.
