Keep selling when the internet drops; everything catches up later.

A till and stock system for shops with several branches. The cashier keeps ringing up sales, taking payments and printing receipts during an outage, and each sale is saved safely on the device. When the connection returns, sales and stock changes are sent to the main records. It runs in a browser, as an installable app, or as a Windows and Mac desktop program.

Who it’s for
Retail shop owners and managers with one or more branches and unreliable internet.
The problem it solves

Cloud tills stop working when the internet fails, and stock figures drift when two people edit at once. This keeps trading going and keeps the stock counts correct.

What it does
01
Works offline

Products, stock and sales stay on the device after the first sign-in, protected by a PIN lock.

02
Safe catch-up

Each sale is sent once, and a retry never counts it twice. A rejected sale stays visible so staff can fix it.

03
A full sales counter

Barcode scanning, split payments (cash, card, mobile money, bank transfer), discounts, credit sales, partial returns and thermal receipts.

04
Stock you can trust

Every stock change is a permanent entry, with transfers between branches, stock counts and supplier purchases.

05
Customer debts and suppliers

See who owes what, with debt ageing, and keep customer and supplier contacts.

06
Bulk import and export

Load products from CSV, Excel and other files with a preview and row-by-row error messages, and export reports.

07
Branch roles and an audit trail

Staff permissions are set per branch, and a history records who changed what.
