CASHIER MODE
A calmer counter for every shift.
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.

How the pieces connect
From first sale to end-of-day report.
AT THE COUNTER
The cashier sees only what the moment needs.
Checkout, product lookup, sales history, returns, the cash drawer, and the clock — reachable in one tap, on a screen simple enough for a new hire on day one. Owner-only pages stay hidden behind the PIN.
- Search and scan in one field
- Park and resume sales
- Returns with the original record
- Drawer count at shift close
CASHIER VIEW
One screen, one job.
AFTER THE SHIFT
The owner sees the whole day in one place.
Sales totals, payment methods, staff performance, and stock changes roll up automatically from the same device — no uploads, no exports to a spreadsheet, no waiting for a connection. Close the drawer, review the day, make a fresh backup.
- Trends and payment splits
- Staff sales and hours
- Financial statements
- Fresh encrypted backup
OWNER VIEW
The day, already summarized.
The TandemPOS direction
Reliable store tools that respect local data.
Our goal is to help independent stores keep selling and keep their records under their own control, even when the connection is unavailable.
Offline-first operations
Keep products, sales, stock, staff, and accounting records on the store device.
Simple recovery
Move a catalog or full workspace with clear restore files when a device changes.
Better owner visibility
Build clearer sales, financial, payroll, and multi-store summaries without hiding local history.
Future projects
Continue improving hardware setup, guided learning, staff workflows, and store-to-store tools.
