Features

Everything a retail checkout needs.

Built for real stores: fast, fiscal-compliant, and resilient when the network isn't.

1C / BAS HTTP API

Products, prices, stock and sales documents sync both ways over HTTP. No file exchange, no manual import.

Offline mode

SQLite on the register. Sales continue when the link is down; everything syncs automatically when it's back.

Vchasno.Kasa

Fiscal receipts, Z-reports and Device Manager integration. Ukraine fiscal compliance out of the box.

Customer display

Second monitor for the buyer: live cart, totals and promo slides. Looks the part at the counter.

Scales & scanner

Weighed goods over COM, USB, TCP or WebSocket. Barcode scanner, weighing and labels at the counter.

Retail operations

Payments, debt, bonuses, orders, markdown, labels, expenses and delivery PDFs — the full shop day.
