State what changed
Published September 9, 2026.
A useful backorder message names the affected item, the date the estimate changed, and the source of the current estimate. It should also distinguish a supplier estimate from inventory already received. That small distinction helps customers judge uncertainty.
Put the choices side by side
Show the customer how to wait, switch to an approved substitute, split the order, or cancel the affected item. Include price, delivery, and refund effects that are confirmed in the account. Do not steer the customer toward the option that is easiest for the queue.
Assign ownership after the reply
Record the selected option and the next operational checkpoint. If no response arrives, follow the published policy rather than improvising. Track repeat estimate changes and contacts because they may reveal a supply or notification problem that support cannot solve alone.
This script works well with an address correction workflow and a refund escalation workflow.
