Billing & POS
The fastest way to ring up an order
Touch-first billing built for Indian kitchens — GST-correct invoices, UPI and cash, KOTs to every station, and full offline mode when the internet drops.
Watch a bill become a GST-correct invoice
The counter screen, traced line by line: items in, KOTs fired, and an invoice whose tax treatment is decided by law — your registration type, not a settings guess.
- Tax invoice & bill of supply
- Section 9(5) orders tagged
- Per-head GST rounding
- Works fully offline
Ring a bill in seconds
Ring a bill in seconds
Tap items, apply modifiers, split a bill by item or guest. Totals and taxes recompute live as you go — no mental math at the counter.
GST that's correct by law, not by luck
Tax invoices or bills of supply pick themselves from your registration type. Per-head rounding, HSN codes, and Section 9(5) aggregator orders are handled for you.
Takes cash, UPI, and cards
Show a dynamic UPI QR, split a bill across methods, and settle the drawer at end of day with every rupee traced back to its order.
Keeps selling when the Wi-Fi dies
Bills ring, print, and queue fully offline. The moment you reconnect everything syncs — no duplicates, no lost orders.

Frequently asked
Do I need to buy a special till or hardware?
No. Keystonne OS runs on the Android phone, tablet, or laptop you already own, and prints to most thermal printers over USB or the network.
Will it work without the internet?
Yes. Billing, KOTs, and printing all work offline; everything syncs automatically the moment you reconnect.
Is the GST really handled for me?
Yes. Invoice type, tax heads, rounding, and aggregator orders follow the current rules as dated data, and you get a filing-ready export for Tally or Zoho.
How much does it cost?
The POS is free for 6 months. No per-terminal licence and no monthly seat fee.
