Codex to build a household stock list for discount day

Eriko wanted to make a monthly ten percent shopping discount useful without buying items the household already had. Living in Sydney meant buying meat, vegetables, everyday supplies and Japanese goods from different places, while actual stock levels were still managed from memory.

They first created an Excel inventory with product names, purchase locations, units, storage locations and current and minimum quantities. Minimum stock was more useful for shopping decisions than an estimate of how long every item would last. But updating Excel from the kitchen or bathroom was awkward.

Eriko gave the workbook to Codex and requested an application usable from Windows and an iPhone. The build took more than two hours and ended with a phone accessible interface. About eighty products were registered. Controls included adding or subtracting stock, marking an item used up and recording that its quantity had been checked. Filters showed what to buy at Coles, other stores or during a return trip to Japan.

The author had only just begun operating the app. Receipt reading and consumption based purchase suggestions were future plans, not completed features. Eriko still needed to update real stock and assess the minimum levels. No saving or reduction in duplicate purchases had yet been measured.
