Business situation
A brief outage produces uncertain orders, repeated kitchen tickets and delayed payment confirmations.
The key decision
Agree what can continue locally and what needs online verification. Separate preparation authority from confirmed payment.
How implementation works
Use unique order and print-task identities. Synchronize after reconnecting and query provider payment results before marking paid.
Business value and evolution
Staff have an executable outage procedure and a recovery queue. Acceptance includes disconnections, restarts and duplicate attempts.
