01The challenge
In a barbershop the internet drops and the register can’t stop. It needed a system that charges, schedules and tracks each barber’s commission even offline, and syncs on its own when the signal is back.
02What we built
What we built
01
Offline checkout
Every sale is stored on the device first. A queue sends it to the server as soon as the signal returns, with no duplicates.
02
Cash, debts, expenses and commissions
The owner sees what came in, who owes, what was spent and each barber’s share, without doing math by hand.
03
Several shops, separate data
Each shop sees only its own data. Three roles: admin, cashier and barber.
04Craft details
Technical decisions, in plain words.
01
Offline queue in IndexedDB
Operations stack up in the browser and are replayed in order. If the internet drops mid-sale, nothing is lost.
02
Per-shop security
Access rules live in the database: even if someone tampers with the app, they can’t read another shop.
03
Instant feedback
The screen updates before the server answers, so the barber never waits with the customer in front of them.
