Jamanvar by Kelviontech

Offline & Hardware

Keeps running when the internet doesn't.

Your internet will drop at some point, probably on a Friday night. Jamanvar keeps billing, printing and kitchen routing going, and works with hardware you already own.

What it does

Service doesn't stop when the internet does

If you've run a restaurant in India, you know the feeling: the router blinks, the cloud billing screen spins, and you have a full house and a queue of guests holding their cards. Software that needs a perfect connection to take an order is software that will fail you at exactly the wrong time.

Jamanvar is built to work offline first. Orders, KOTs and bills are handled on the device in front of you, and kitchen routing carries on locally. When the connection comes back, everything syncs to the cloud in both directions on its own. Nobody has to re-enter anything, and no bill goes missing.

The other worry is hardware. Nobody wants to replace working terminals just to change software. Jamanvar runs on standard ESC/POS printers and on Windows, Android and iPad devices, so what you own probably works. If you'd rather start fresh, there are pre-tested kits with POS terminals, thermal printers, KDS tablets and captain handhelds that come ready to plug in.

A good fit for restaurants where the connection is unreliable, and for owners who'd rather keep the terminals and printers they already have.

In more detail

Offline & Hardware on a working day

A counter where everything talks to each other

A working counter is a terminal, a receipt printer and a payment device that all need to agree with each other. Jamanvar's hardware kits are tested as a set, so the terminal prints to the printer and the bill matches the payment without an afternoon of settings.

If you already own the equipment, there's no need to buy it again. Standard ESC/POS printers and Windows, Android and iPad devices are supported.

We also help with the fiddly parts: pairing thermal printers over USB or LAN, connecting cash drawers and getting kitchen tablets talking to the counter.

The whole kit, tested as a set

A full kit covers every role in the restaurant: a POS terminal for the counter, a thermal printer for receipts and KOTs, a KDS tablet for the pass, and a captain handheld for the floor. Each one shows the Jamanvar interface it's meant for.

Because they've been tested together, a KOT fired from the handheld arrives on the kitchen tablet, and the bill on the terminal prints on the counter printer, on the first day.

When the router goes quiet, the counter doesn't

If the internet drops, the POS shows that it's offline and carries on. Orders, KOTs and bills are handled locally, and a small counter shows how many orders and bills are waiting to sync.

When the connection returns, everything goes up to the cloud automatically, in both directions. The owner's dashboard fills in, nothing is re-entered, and the cashier never has to do anything.

Where it fits

Restaurants that get the most out of it

  1. 01

    Restaurants with patchy internet

    Offline-first means an outage is an inconvenience for the router, not for your dining room.

  2. 02

    Owners reusing existing equipment

    Bring your printers and terminals. Standard ESC/POS printers and common devices are supported.

  3. 03

    New outlets setting up from scratch

    A tested kit means the counter, printer, kitchen tablet and captain handheld are chosen to work together from the start.

Where it fits in the flow

Where hardware and offline mode sit in the flow

Hardware and offline mode aren't a step in the flow. They're what the whole flow runs on, at every stage from the first order to the last report.

Questions owners ask

About Offline & Hardware

Can we use the printers and devices we already have?
In most cases, yes. Jamanvar supports standard ESC/POS printers and runs on Windows, Android and iPad. Share your device list when you book a demo and we'll confirm what works.
What exactly keeps working when the internet goes down?
Billing, KOT printing and kitchen routing all continue locally. Cloud-only features, like the owner's live dashboard on your phone, catch up as soon as you're back online.
Do we have to buy hardware from you?
No. Hardware kits are there for owners who want tested, ready-to-run equipment, but the software works on standard devices you may already own.
Who sets up the printers and the cash drawer?
We help with that. Support includes configuring ESC/POS thermal printers, USB and LAN connections, cash drawers and kitchen display tablets.
How quickly can we go live?
Most restaurants are live within 24 to 48 hours. Once we have your menu and table count, we configure the system, train your team and run a test billing cycle before you open.
