I believe Starship BOI can package the items in any way you want, including by serial. Starship then knows what's in each package, including Invoice#, item#, serial, etc. It also creates the shipping labels so it knows the tracking number of each package. That info is sent to TrueCommerce allowing you to do the ASN. It doesn't go through Sage100. Give Starship a call, I could be misunderstanding all that is needed by your customer
