Keep selling when the internet & power cut out
POS Line is offline-first. When the connection drops, your till keeps ringing sales — they're queued safely on the device and synced to the server the moment you're back online. Nothing lost, nothing double-posted.
A dropped connection shouldn't stop a sale
In Pakistan, the internet flickers and the power goes out — sometimes both at once. POS Line is designed so a cut never costs you a sale or creates a messy duplicate. You ring it up, and the system handles the rest when you're back online.
How POS Line stays open through a cut
Ring sales with no internet
When the connection is gone, the till keeps working. Each sale is queued locally on the device so your line never stops moving.
Automatic safe sync on reconnect
The instant the device is back online, queued sales upload to the server on their own — no manual export, no re-entry.
Idempotent — never double-posted
Reconciliation is idempotent. Even if a sync retries after a flaky connection, each sale is recorded exactly once — never double-charged or double-recorded.
Survives load-shedding
A power cut mid-shift won't lose your work. Sales already queued on the device are held safely until things come back.
Nothing slips through the cracks
Every offline sale is accounted for when it syncs, so your records stay complete and your day's totals add up.
Nothing to set up
Offline handling works out of the box. You don't toggle a mode or remember to switch back — POS Line just keeps going.
How it works
Ring the sale
The connection drops, but you keep checking customers out. Each sale is saved locally on the device, in the browser.
Queue it locally
Offline sales sit in a safe local queue, waiting. Your shift carries on as normal — no error screens, no lost orders.
Reconnect and sync
When the device is back online, the queue reconciles to the server idempotently — each sale lands exactly once.
Honest scope: the device does need to come back online for queued sales to sync — POS Line holds them safely until it does.
Frequently asked questions
- Can I keep selling when the internet goes down?
- Yes. POS Line rings sales even with no connection. Each sale is queued locally on the device and held until the connection returns.
- What happens to my offline sales when I reconnect?
- When the device comes back online, queued sales sync automatically to the server. The sync is idempotent, so a sale is recorded exactly once even if the connection drops mid-sync.
- Could a sale be recorded or charged twice?
- No. Reconciliation is idempotent. If a sync retries after a flaky connection, the server recognises the same sale and never double-posts or double-records it.
- Do I need to do anything for the sales to upload?
- The device must come back online to sync. Once it reconnects, syncing happens automatically in the background — there is no manual export or re-entry step.
