Extending the delivery date

For the provider

From the order page (in progress): "Request extension" with the number of days (up to 30) and the reason. One request awaiting an answer at a time, two at most per order. After that, agree with the client in the conversation.

For the client

You get a notification and accept or decline from the order page. On acceptance the delivery date moves and the order log records it; on refusal the date stays and you may cancel after it passes.

On-time rate

An approved extension counts as the new date, so delivering by it counts as "on time".
