The Stock-Out Predictor

Client: Brook Lane PharmacyCommunity pharmacy · Chesterfield

Brook Lane Pharmacy, Chesterfield high street · Friendly, practical, a little sceptical

Mrs. Pike's nephew told her she needs AI. What Brook Lane Pharmacy actually needs is to know, on Friday, what will run out before Monday's delivery. Two years of sales sit in the old till's backup, scrambled.

Team goal · 1,000 gems

Everyone on this contract works toward one sign-off from Brook Lane Pharmacy. Sign-off means the predictor launches in the shop and Brook Lane moves its new till support to us.

The client's system

Till backup

The old till shifted product names by a number printed on each page, wrapped notes in Base64, and used one fixed shift on its weekly reports.
