When using RestockAMZ and Purchasing together, it is important to understand the difference between their recommendations and functionalities. 

Purchasing

The Purchasing section will be your go-to for reordering recommendations to your local inventory from your suppliers. The recommendations shown in Purchasing are based on your supplier-to-local lead times and order intervals. Purchasing will take into account the full picture of your inventory including your open POs, current warehouse inventory, and all Amazon inventory to provide your reorder recommendations using our forecast models and daily sales rate calculations.

RestockAMZ

RestockAMZ will also provide you with recommendations based on our forecast models and daily sales rate calculations, but these recommendations are FBA restock recommendations for both supplier-to-FBA and local-to-FBA, taking into account their differing lead times. In addition to recommending enough inventory to cover the lead time into Amazon, target days of FBA inventory quantity will be added to this recommendation. For example, if you set the target to 60 days of inventory in stock at Amazon, then your restock recommendations will be based on the provided lead time into FBA + 60 days of stock coverage. RestockAMZ will take into account all Amazon inventory, including inbound inventory to provide your restock recommendation. If you are restocking FBA from a supplier, your recommendation will also take into account open purchase orders. 

Daily Sales Rate Settings

RestockAMZ and Purchasing both use the same methodology for calculating daily sales rates but differ based on your average weight settings for each and the differences in FBA restock vs Reordering mentioned above. They are labeled as "Purchasing Daily Sales Rate Settings" or "RestockAMZ Daily Sales Rate Settings" for clarity. We recommend using the automatically adjusted weightings for both or setting the same weights for RestockAMZ and Purchasing for continuity.
