Warehouse Types:
Used for organization and filtering. For example, none of my Supplier Warehouses are displayed in the Warehouse Screen (they are hidden), because I don’t care about their Stock counts. Only my Local Warehouses appear in this screen.
Local Warehouses: Shop, Bodega
Supplier Warehouses: a Warehouse for every supplier I have
Document Types:
Documents contain Transactions. You buy product A, B, and C from your supplier. For each product bought, there is a Purchase Transaction. The Purchase Document contains 3 Transactions (1 for each Product). If I want to move a case of Bagels, 3 Trays of Croissants, and a Bottle of Rum from my onsite Shop (Local) Warehouse to my offsite Bodega (Local) Warehouse, I use a Transfer Doc which contains 3 Transfer Transactions (1 for each Product).
