After sending out an Invoice and it has been paid, it would be useful if that invoice could have an additional status, indicating (1) that the goods have been "despatched", then (2) later as "delivered"

Similarly, on a Bill, After the bill has been paid, it ships, and it would be useful if the bill could be marked as (1) shipped then (2) later as "received".

And in both cases, there is an associated shipping document, such as Air Waybill Number and associated shipping agency. The AWB can be further enhanced to provide a link to the tracking service provided by shipping companies.

All this together allows the user to keep a track of goods in transit in and out, allowing identification of any where issues may have occurred.

Even better: If a client order is dependent on receipt of goods from a supplier, the cross dependency of a client invoice to a 3rd party merchant bill could be made.
