Shelf: a stock ledger for Nigerian Instagram shops

Field notes

Shelf organizes stock around a permanent movement ledger rather than an editable inventory number. The page describes named staff accounts with restricted visibility, offline sales that queue until a connection returns, and exports for accountants who do not need to sign in. Its examples adapt units to the trade—yards for fabric, pairs for shoes, portions for food—and distinguish a customer claiming to have paid from money actually arriving.
