By using the Inter-warehouse transit location, two shipping addresses on the Company, a location outside the main warehouse location (representing the Amazon inventory) and an operation type with a push rule, any delivery that is made to the Amazon "warehouse" (just a location) will generate a "Receipt" so that there is a way to record the outgoing delivery (performed by the Company) and incoming receipt (performed by Amazon, but then performed by the Company after Amazon verifies quantity and reports back any poor quality or damaged products.)
