Module 15 · Every plan

No network. Still trading. Nothing double-charged when it returns.

Trading continues with no network at all. Not a read-only cache. New orders, new totals, new printed slips.

What is in it

Offline mode, feature by feature.

Offline mode is on every plan, from AED 149 per outlet per month on a 2-year term, and support is a person in Dubai, any hour of any day.

Local order state

The device runs the same order maths the server does, from the same rules.

Idempotent replay

Each operation carries a client id. A replayed batch is recognised and ignored, so nothing double-charges.

Idempotent replay

Device-rendered slips

ESC/POS bytes are built on the device, so the kitchen ticket still prints.

Queued mutations

Everything you do is queued locally and drained in order when the line returns.

Local numbering

Offline orders show a local number until the server issues the real one.

Local numbering

Visible state

Connection and queue depth are on the chrome, so staff know what is happening.

How it works

Trades, queues, replays once.

Replay onceEvery operation carries a client id, so a replayed batch is recognised and ignored rather than charged twice.

Watch it done

What happens when the network drops0:39
The steps
  1. The network drops. Offline shows at the top, and the till carries on.
  2. Start an order as usual.
  3. Add the dishes. The menu comes from the last sync.
  4. Send it to the kitchen. With no server, the ticket prints straight from this device.
  5. Until it syncs, the order carries this till's own number, like A1.
  6. When the line is back, the till sends what it kept. In Orders it has its server number.

All 42 are in the Academy, in the order to watch them.

Before you believe it

The three questions everyone asks.

What still works with no internet?

Taking orders, settling bills and printing tickets over USB or Bluetooth in Chrome, or through the browser’s print window. Network printers need the internet. Everything queues and replays in order when the line returns.

What if two tills go offline at once?

Each keeps its own local numbering and the queue merges on return with no duplicates. Replays are detected.

Which plan includes offline mode?

Every plan. Tab costs AED 149 per outlet a month on a two-year term, 169 billed yearly or 199 monthly, with 30 days free and no card.
