Rush hour में internet चला गया—क्या POS data खोए बिना बिक्री जारी रख सकता है?

Internet outage से store को रुकना, sales duplicate होना, payments खोना या inventory corrupt होना जरूरी नहीं। Local storage, offline limits, receipt numbering, sync conflicts और recovery समझें।

Offline mode business continuity feature है

Offline mode is a full business continuity design covering products, prices, taxes, permissions, payments, receipts, storage, inventory, and later synchronization.

The system should clearly define which actions continue offline and which require central data.

एक real outage सोचें: Offline mode is a full business continuity design covering products, prices, taxes, permissions, payments, receipts, storage, inventory, and later synchronization. Local records should contain complete sale details, device, employee, branch, sequence, and synchronization status. Offline card payments require separate risk limits because later authorization can fail. Cash, offline card, device restart, same low-stock item on two terminals, price change, duplicate sync retry और upload से पहले refund test करें।

एक real outage सोचें: Idempotency is required so retrying synchronization does not create duplicate sales. Receipt, order, and transaction identifiers must remain unique across all devices. The system should clearly define which actions continue offline and which require central data. Cash, offline card, device restart, same low-stock item on two terminals, price change, duplicate sync retry और upload से पहले refund test करें।

एक real outage सोचें: Sensitive data should remain encrypted and role-based access should still apply without the server. Stores should deliberately test outages, restarts, reconnection, duplicates, inventory, receipts, and payment settlement. When connectivity returns, transactions should upload through a controlled queue with confirmation and retry handling.
