In our case, our company import goods from different places in the world.  Travel or transit time is around 20-30 days before reach our warehouse in US.  Our suppliers bill are usually based on B/L date and we want to post that Bill as soon the supplier send it to us so terms start running.  To do so, we have to enter all goods in QB that are still in transit and that is a problem to control inventories.   To have BILL DATE and RECEIPT DATE is very useful to trace and control inventories.    This is a very good idea to be incorporated in your software.  For sure people will use it and love it.
