Estorr

Small shops — especially fabric shops that sell by the yard — run on shared phones, busy counters and unreliable data. A few metres here and a discount there quietly add up.

Give the owner numbers they can trust without slowing down the storekeeper — and without depending on the network.

Four large actions on the home screen — Sell, Stock, Money, My Day — with pictures and few words:

• Picture-led selling with yard cuts, split payments across cash, Mobile Money, bank and credit, returns and credit repayment.
• “Sold for less?” records every discount with a reason.
• Stock intake, stock counts and price groups.
• Shifts, expenses with receipt photos, cash drops, a deficit board and manager flags.
• Bluetooth thermal receipts, and reports by day, week, month or range with CSV export.
• Staff invitations with a per-person PIN on shared devices, and shop approval by a platform administrator.

A Flutter app with a local SQLite database and an ordered outbox, on Firebase with TypeScript Cloud Functions that re-derive totals, run stock checks and send daily summaries. Records are append-only: a sale is voided, never erased.

• Local first: every action is saved on the device before it syncs.
• Accountability without accusation: flags and deficits are shown, not blamed.
• Big targets, few words, for staff with varied literacy.

Estorr v1.1 is built: signed Android release builds and a deployed cloud back end. It is not yet on the app stores.
