In Inventory Planner, Amazon stores have two warehouses: FBA (Amazon warehouse) and FBM.
FBA stock is updated when Amazon receives inbound shipment. We use _GET_AFN_INVENTORY_DATA_BY_COUNTRY_ report. The stock is normally the stock in Amazon plus stock reserved due to FC transfers (they are available for sale). This stock also does not include reserved due to customer orders or due to FC processing (usually damaged goods/returns).
Inventory Planner ignores sales orders with fulfillment-channel Amazon and sales-channel Non-Amazon if item-status is Unshipped. Such orders are usually removal orders and should not count for replenishment.
Replenishment for FBA can be performed in one of the following ways:
- Purchase stock from supplier and ship directly to Amazon warehouse. In Inventory Planner, it corresponds to the creation of a purchase order with FBA as the destination. Such purchase order can be also be saved as Amazon inbound shipment.
- Purchase stock from a supplier to your own warehouse/location which is available as FBM stock. In Inventory Planner, this is a purchase order to main warehouse and does not correspond to anything in Amazon. Once you receive products to your warehouse, you then ship smaller quantities to Amazon. In this case FBA listings should have shorter lead times and days-of-stock periods and the replenishment number will reflect how many products should be sent to Amazon. To proceed create a transfer from FBM to FBA which can also be saved as an Amazon inbound shipment.
- Purchase stock from supplier and store in your own warehouse/location which is maintained in a different e-commerce system (for example, Shopify)
Note that Inventory Planner also pulls existing inbound shipments from Amazon and records them as transfers from FBM to FBA.
You can save Inventory Planner purchase order or transfer as inbound shipment in Amazon. In PO Edit screen, select 'amazon warehouse' as the destination warehouse:
and make sure Save in Amazon checkbox located near Save button on the bottom is marked:
You can also set shipment name by entering it in PO# field (in advanced mode). If you leave it black, Inventory Planner will use identifier generated by Amazon for the name.
If UOM (units of measurement) is set for a variant, it will be used as quantity in case in inbound shipment.
