Offline POS Kenya
POS That Works Even When Your Internet Doesn't
In Kenya, internet outages and power cuts are a business reality. sell.ke's offline mode keeps your checkout running when connectivity drops — and syncs every transaction automatically when it returns.
Real scenarios where offline mode saves the day
These aren't edge cases in Kenya — they happen every week in shops across the country.
Power outage
Mombasa Road, 3 PM. KPLC cuts power. Your generator kicks in — but your internet router is down. sell.ke keeps running. Cashiers process sales without missing a beat.
Remote location
A branch in Kisumu or Eldoret with unstable fibre. sell.ke's offline mode handles the full day's trading. When connectivity returns, everything syncs.
Busy market days
Saturday morning rush. Slow Safaricom data. sell.ke's local database means there's no lag — checkout speed isn't affected by a slow connection.
How sell.ke offline mode works
Local database always on device
sell.ke keeps a local copy of your product catalogue, pricing, and open sessions on every device. This copy updates continuously while online.
Internet drops — nothing changes for the cashier
Cashiers see no error message, no disruption. sell.ke detects the outage silently and switches to the local copy. Checkout speed is unaffected.
Sales queue locally
Every transaction is saved to a local encrypted queue on the device. The cashier prints receipts normally. Stock levels are updated on the local copy.
Auto-sync when internet returns
The moment connectivity is restored — even for a few seconds — sell.ke syncs the transaction queue to the cloud. Your head office dashboard updates immediately.
No data loss, no duplicates
sell.ke uses conflict resolution logic to merge offline transactions correctly. If two devices were offline simultaneously, their queues merge without creating duplicate sales.

Offline POS Kenya — frequently asked questions
How does offline mode work in sell.ke?
sell.ke stores your product catalogue, pricing, and open sessions locally on the device. When internet is unavailable, the POS reads from this local copy and writes sales to a local queue. The moment connectivity returns — even briefly — all queued transactions sync to the cloud.
Can I accept M-Pesa when offline?
M-Pesa payments require a live Safaricom connection for confirmation. In offline mode, you can still accept cash and card payments. Some businesses keep a dedicated mobile hotspot as a backup for M-Pesa specifically.
How long can sell.ke operate in offline mode?
Indefinitely. There is no time limit on offline mode. If a branch location has limited internet, it can operate in offline mode all day and sync during brief connectivity windows.
Is data safe when offline?
Yes. sell.ke encrypts the local data store on the device. Even if the device is lost, the data is protected. Once synced to the cloud, it is backed up automatically.
What happens if two devices go offline simultaneously?
Each device maintains its own queue. When both come back online, sell.ke merges the transactions with proper timestamps. Stock levels are reconciled automatically — no manual intervention needed.
