Why offline-first
The internet goes down. Dinner service does not.
Most cloud POS systems stop the moment the line drops, right in the middle of a rush. ZaikaLab is built the other way around: the outlet works on its own, and the cloud catches up later.
Everything is in sync. Flip the line down to see what a real outage does.
The difference
Two ways to build a POS. Only one keeps billing in an outage.
Cloud-first POS
- The line drops and the screen freezes mid-order.
- Every tap waits on a round trip to a server.
- An outage at 8pm on a Saturday is an outage in your billing.
- Your data lives somewhere you cannot reach without the internet.
ZaikaLab, offline-first
- The till keeps taking orders and printing bills, no internet needed.
- Every action is instant, because it is local.
- An outage is invisible to the floor; sync simply waits.
- The full record is on your machine, yours to keep.
How it is built
Four rules the whole system follows.
These are not settings you turn on. They are how ZaikaLab is put together, top to bottom.
The till is the source of truth
The outlet’s Windows machine owns every order, ticket and bill. Nothing has to be online for it to be true.
Captains send commands
Handsets and terminals ask the till to do things over the local network. They never own the order themselves.
The cloud is a copy
The outlet syncs a copy up whenever it can. The cloud reads for the owner; it never edits a transaction.
The licence is enforced offline
A signed licence on the machine keeps it running through an outage, and only goes read-only if it truly lapses.
The shape of it
The outlet runs on its own network. The cloud is downstream.
Captains and the kitchen talk to the till over the outlet's own LAN, so orders and bills never leave the building to happen. The cloud is the one leg that needs the internet, and it only ever receives a copy.
How a sale flows
From the order to the cloud, in five steps.
The first four happen at the outlet, with or without the internet. Only the last one needs a connection, and it is never in anybody’s way.
- 1
Take the order
On the till, or on a captain’s phone at the table. It is written to the outlet at once.
- 2
Fire the kitchen
The order becomes a KOT and prints at the right station, immediately, on the local network.
- 3
Print the bill
GST computed to the paise, a sequential invoice number, a clean printed bill.
- 4
Settle it
Cash, card, UPI or a tab. The outlet records it and the drawer reconciles at close.
- 5
Sync when online
The moment a connection is back, the outlet catches the cloud up. Nothing was waiting on it.
Your data
Offline-first is also data you own.
Your data sits on your machine
The full record lives at the outlet. The cloud copy is for reporting, and losing the internet loses you nothing.
Every change is written down
Actions go to an audit log, and synced rows are soft-deleted, so a mistake can be traced and undone.
