POS operations guide
Internet failure should not stop a billing counter. A practical POS setup keeps item data, tax groups, printers and local reports available, then syncs or exports later when the connection returns.
Offline billing matters for restaurants, grocery stores, pharmacies, supermarkets, remote-area shops, pop-up counters, food trucks and any business where customers cannot wait for internet recovery.
The POS bills locally, prints receipts, records cash or offline payment mode, updates local stock, marks unsynced activity and syncs or exports reports when internet returns.
