When a vendor ships inventory directly to Amazon FBA, enter the bill against your source warehouse — not the FBA warehouse. This is typically your local or default warehouse configured in your ConnectStock file settings.
Why Does This Matter?
ConnectBooks treats the source warehouse as the starting point for all FBA shipments. When Amazon reports a new FBA shipment, ConnectBooks automatically moves the inventory from the source warehouse → In Transit → FBA warehouse once Amazon confirms receipt.
If you assign the bill directly to the FBA warehouse, the inventory appears as already received by Amazon — even though it hasn't arrived yet. This causes inaccurate inventory counts and sync issues. When ConnectBooks later detects the FBA shipment, it expects the inventory to have originated from your source warehouse. If it was never logged there, the transfer will be incorrect and your data will be off.
Won't My Local Warehouse Show Inventory That Isn't There?
No. The local warehouse is only a temporary origin point, not where the inventory actually sits. As soon as Amazon reports the FBA shipment, ConnectBooks immediately transfers the inventory out of the local warehouse and into In Transit. Your local warehouse balance stays accurate at all times.
In Summary
Always enter vendor bills to your source warehouse, even when shipping directly to FBA. ConnectBooks handles the rest automatically.
