Combined warehouses

A combined warehouse is used to see total demand from more than one warehouse. It allows you to choose which warehouses are included in the total demand, i.e. which contribute to the sales information for the combined warehouse. You also specify which warehouses to consider for inventory totals.

The following scenarios are examples of merchants who might find a combined warehouse useful:

  • Amazon sellers using a staging warehouse before forwarding inventory to an FBA (fulfilled by Amazon) warehouse
  • Merchants with multiple locations who want to see the total demand for products to order from overseas vendors
  • Stores selling both on their own domain and Amazon that want to see demand for different regions. In this case, Amazon US + Amazon CA + can be shown together. Then, Amazon GB (showing pan-EU demand) + can be shown in a different combined warehouse

Combined warehouses are used for replenishment when you need to know demand from more than one warehouse. You may want to know the total stock amount at more than one location so you don't over-order. Conversely, you may need to specify that two warehouses use the same stock to fulfill customer orders. A combined warehouse ensures that you're considering all stock you have on hand while not double-counting stock available to different warehouses.

Create a combined warehouse

To set up your combined warehouse, go to Account > Settings > Connections & Warehouses.

First, check to see which warehouses are currently enabled. If you need to see demand for a specific location, click the corresponding box in the Enabled column.


Next click + New Combined Warehouse. Name your combined warehouse, then select which warehouse you wish to combine. In the Details column, select how you handle stock. 


  • Combine sales, stock and purchase orders: Sales history, inventory availability and purchase order quantities from this warehouse are all included in the combined warehouse totals.
  • Combine sales, ignore stock and purchase orders: This will include sales history but not inventory availability or purchase order quantities from this warehouse. This may be handy if the warehouse contains 'virtual' stock.
  • Combine sales, share stock with xxxx, combine purchase orders: Sales history is combined. Inventory is taken from the selected shared warehouse unless there is no inventory in the shared warehouse, in which case it's taken from the current warehouse.
  • Combine purchase orders, ignore sales and stock: Only purchase order quantities are taken from this warehouse.

Finally, click Create
