If a vendor ships inventory directly to Amazon FBA, still enter the bill to the shipment's source warehouse, not the FBA Warehouse. The source warehouse is your Local Warehouse by default.

When the shipment is shipped, ConnectBooks moves the units from your Local Warehouse to your Transit Warehouse. This happens on its own when Auto Sync is on. Then, once Amazon receives the goods, ConnectBooks moves them to your FBA Warehouse.

If you enter the bill directly to the FBA Warehouse, the inventory will look like it's already there, even though it's still in transit. This makes your inventory counts wrong, because ConnectBooks expects the inventory to start from your source warehouse.

The source warehouse is the starting point for all FBA transfers in ConnectBooks. Even if the inventory ships directly from your vendor to Amazon, ConnectBooks uses it to track that movement. Entering the bill there keeps your inventory data accurate and your transfers working properly.

You set the Local Warehouse and Transit Warehouse for each store under Manage Warehouses in your inventory file's Inventory & Warehouse settings. If you have the FBA Shipment Source Warehouse setting on, each shipment uses its own source warehouse instead.

Which warehouse do I pick on the bill?

The shipment's source warehouse. By default, that's the Local Warehouse set for the store.

When does the stock leave the Local Warehouse?

When the shipment is shipped. ConnectBooks does this on its own when Auto Sync is on. With Auto Sync off, click Transfer on the shipment.

What if I ship from more than 1 warehouse?

Turn on the FBA Shipment Source Warehouse setting. Then each shipment uses its own source warehouse, and you enter the bill to that one.
