As connecting Amazon creates warehouses for every marketplace in a region, you may end up with several warehouses you do not need.

You should only enable warehouses which you need to evaluate independently for forecasting and replenishment planning purposes.

You can also disable an FBM warehouse if you’re actually fulfilling FBM orders from another location (such as your Shopify warehouse).

You can combine your Amazon warehouses to calculate forecasts and replenishment recommendations based on their totaled data. You can then disable the individual warehouses once they’ve been combined if you don’t want to evaluate them independently too.

For example, if you’re using Pan-European Fulfilment, Amazon will move your stock between countries to meet demand, so you would only consider replenishment needs for your total demand.

Combining warehouses also reduces the number of warehouses you see listed in Inventory Planner, making it easier to use.

In the following example, sales, stock and purchase orders from the the Shopify “Shopify US” have been combined with sales and purchase orders from the Amazon US “FBM” connection into a single combined warehouse. Stock from the FBM connection isn’t included, because all the stock is held in the Shopify US warehouse, where orders from both connections are fulfilled.

Inventory Planner creates a single, dedicated warehouse for a seller’s FBM orders within a single Amazon region. Similar to FBA warehouses, Inventory Planner creates this warehouse regardless of the number of warehouses you already have and what locations they’re in.

If you use multiple locations or warehouses for your FBM orders, we recommend connecting your storefront (e.g. Shopify, Bigcommerce) or ERP platform to sync your FBM data instead of using the singular warehouse created by the Amazon connector.
