Offline checkout
Keep selling with local browser storage and recoverable backups when the connection drops.
Local-first point of sale
TandemPOS keeps checkout, products, stock, staff time, payroll, and financial records close to the register. Manage your account, learn the system, or prepare a sample catalog in the public demo workspace.
The demo uses temporary catalog data only. Subscription status is checked online; customer register records stay on each register.

See the workflow
These previews use the same labels and flows as TandemPOS so a new owner can understand the day-to-day experience in seconds.
Owners can lock a device with a PIN so cashiers see checkout, products, history, returns, drawer, receivables, hardware, and backup tools while owner pages stay out of the way.
Try the cashier sampleBar charts, payment methods, staff sales, and custom date ranges help owners act quickly.
Financial statements, receivables, payables, account logs, and payroll review live in their own clear pages.
Downloads
Your records stay on your devices; TandemPOS does not keep a cloud copy of POS transactions. Supported sales, returns, purchases, expenses, and stock changes transfer over encrypted local Wi-Fi on a per-register schedule (one minute by default) while the apps remain open and awake; after either app restarts, scan a fresh QR to reconnect. Other setup, account, staff, and cash-shift records remain on the device where they were entered.

Records stay on the store’s own computers and tablets. Supported records transfer over encrypted local Wi-Fi on each register’s schedule (one minute by default) while the apps remain open and awake; after either app restarts, scan a fresh QR to reconnect. Start one free seven-day trial from your account page, then choose a paid plan when you are ready. A three-day grace period follows a missed renewal.
Read the guides, build a sample catalog, and download a catalog restore point. Demo data never becomes a real transaction.

Our goal is to help independent stores keep selling and keep their records under their own control, even when the connection is unavailable.
Keep products, sales, stock, staff, and accounting records on the store device.
Move a catalog or full workspace with clear restore files when a device changes.
Build clearer sales, financial, payroll, and multi-store summaries without hiding local history.
Continue improving hardware setup, guided learning, staff workflows, and store-to-store tools.
