Every POS rollout we've shipped assumes the network will drop mid-transaction - because eventually, it will. Designing offline-first means the terminal can complete a sale, print a receipt, and queue the sync entirely without a live connection.
The hard part isn't the offline write path - it's conflict resolution when multiple terminals reconnect and try to reconcile inventory counts simultaneously. We use a last-writer-wins strategy for line items and a manual review queue for stock discrepancies over a configurable threshold.
Retailers who've adopted this pattern report zero missed sales during outages that used to mean an hour of pen-and-paper receipts.
