ZaikaLab POS for Windows
Restaurant billing software for Windows that runs the counter.
One Windows PC takes orders, prints kitchen tickets and GST bills, and owns every transaction. Captains and printers talk to it over your own network, so the outlet keeps moving with or without the internet.
On the counter
Everything the counter needs, in one place.
No tab-switching, no second app for billing. The order, the kitchen and the bill are one flow.
Menu and tables on one screen
Categories, items, modifiers and the floor plan in one fast view. Open orders are always a glance away.
Bills that are correct
Item-wise GST, discounts, charges and round-off, with sequential invoice numbers per outlet per financial year.
Printing done properly
KOTs and bills to thermal printers with a clean feed and a real paper cut, centred where it should be.
Fast on keyboard or touch
Every common action has a shortcut, and every tap target is sized for a busy counter.
Roles enforced, not hidden
What a cashier or a manager may do is checked on the counter PC itself, not merely left off the screen.
Never waits on the network
The counter PC is the outlet’s source of truth. No sale, KOT or bill ever blocks on the internet.
Kitchen and print
KOT printing by station, bills with the GST breakup
Orders split to the right station and print as KOTs the moment they are sent. Bills print with the outlet’s header, the GST breakup and a proper cut, every time.
- KOTs route by station, so the tandoor and the cold kitchen each get their own.
- Thermal printing with a standard feed and an automatic paper cut.
- Reprint a bill or a KOT without reopening the order.
UPI on the bill
A QR with the amount already filled in.
Every bill can print a UPI QR for its exact total, so the guest scans and the money lands in your account with no typed amount and no wrong change.
- The QR carries the bill total to the paisa.
- Works with any UPI app the guest already has.
- Cash, card and UPI can be split on one bill.
For the owner
See the day from anywhere, change nothing by accident.
The counter syncs a copy to the cloud whenever it can. Sales, GST and device health show up in the owner app and the console, read-only by design.
- Day summaries, item and category sales, and GST by rate.
- The cloud is a copy; the counter stays the one place data can change.
- Device and sync health, so you know every counter is healthy.

Questions
Restaurant billing software questions
Is ZaikaLab POS restaurant billing software or a full POS?
Both: billing, KOT printing, table management, GST reports and the captain app are one program.
Does the billing software work offline?
Yes. Every bill and KOT is written on the counter PC; the internet is never in the path.
Which printers does it support?
58 mm and 80 mm thermal printers over USB or the network, with a proper feed and cut.
Can waiters take orders on a phone?
Yes, with the ZaikaLab Captain app on Android, paired to the counter once.
How is GST calculated?
In integer paise with half-up rounding, split into CGST and SGST so the two always add up to the tax.
