What is the purpose of List FBA Inventory?
That is a great question. The purpose of List FBA Inventory is mainly for export reasons. Some users still keep a spreadsheet (mainly automatically generated by IL exporting) and a large portion of the manual time that it takes to manage a spreadsheet is from entering in inventory and cost. With List FBA inventory, you can export your batches automatically for these spreadsheets (title, msku, cost per unit etc.)
This page is also used in the scenario you did not enter prices while listing. If you were in a hurry, and just wanted to take advantage of the speed factor of IL… But at the same time would like to add buy cost to your items afterwords (before they even are received) you can also do that in List Inventory.
