Engagement overview
Zion Supermarket · Retail · Ayigya, Kumasi · Started in late 2025
Challenge
Customers often threw their paper receipts into a bin at the supermarket entrance. The owner wanted to reduce paper waste and give customers a record they could open later.
Response
Iderwell connected completed sales to digital receipt pages and sent customers the receipt link by SMS. The work later expanded into inventory records, expiry-date monitoring and item-level profit-after-tax tracking.
Observed outcomes
- 24,000+ sales records connected
- 4,300+ digital receipt pages generated
- 10,000+ units recorded in expiry batches
Figures are rounded from operating records reviewed on 14 July 2026. No customer information or private operational screen is published.
The receipt was only the beginning
Once sales and customer receipts were connected, other gaps became easier to see. Stock batches needed expiry dates, soon-to-expire products needed attention, and the owner needed a clearer view of profit after tax for individual items.
Those needs were added as operating tools around the original receipt service rather than as unrelated software.
What we learnt
A system can start with one visible customer problem and still be designed for the staff who must operate it every day. The useful question was not whether to digitise everything at once. It was which missing connection caused the most waste and uncertainty.
- Start with the point customers and staff already notice
- Keep the sale as the source of the receipt
- Record delivery failures so staff can investigate
- Add new controls only when the operating need is clear
