Logistics
Coverage is a real operational limit and, if it is communicated badly, it turns into a broken promise.
Short answer
When an area has no shipping coverage, the system should stop the delivery promise, explain it clearly, and offer an alternative such as pickup, another logistics option, or human review.
The quote does not return a valid option for the requested address or the area sits outside what the business can actually dispatch.
Promising shipping where there is no real coverage creates broken expectations, complaints, and extra work to correct a commitment that should never have been made.
The right output is to say that coverage is not available right now, avoid continuing as if the order were ready, and offer viable paths so the sale is not lost unnecessarily.
No. There may still be alternatives such as pickup, a nearby zone, or manual review.
It should avoid promising shipping times or prices when coverage has not been truly confirmed.
