Hi Everyone, What tools or settings do I use or change if I want to change the process from Item fulfillment -> Packing slip -> Invoice To Item Fullfillment -> Invoice -> Packing slip

Item fulfillment and invoice is posting transactions so not a good idea if good have not left the warehouse also why in the 1st place you want to reverse it.

I need to show invoice # on my packing slip. Currently, my invoice number does not show on my packing slip until an invoice is generated. Or is there a way for me to add an print option of the packing slip form under invoice? Or anyway for me to automatically print packing slip after invoice is generated?
