Thanks for posting your question in our Community forum. I noticed you are new here, welcome! I’m more than happy to provide you with some additional information on setting up your warehouse locations.
You can set up multiple locations in your Shopify store so that you can track inventory and fulfill orders at your locations. Your locations can be retail stores, warehouses, popups, dropshippers, or any other place where you manage or stock inventory. To make sure your inventory quantities are always accurate, online orders and in-person sales are assigned to locations. If some of your inventory is out of stock at one location, but it’s in stock at another location, then Shopify will split the order so that it can be fulfilled from multiple locations. Check out our help document: Setting up your locations. Or, feel free to watch this great tutorial:
It is important to note that when you create a product, the product is stocked at all locations by default. You can change the list of locations that stock the product and adjust the inventory levels of the product at each location. When orders are placed through any online sales channel, they’re assigned to a location where they should be fulfilled based on the priority list and available inventory. If any location can fulfill the entire order, then the inventory is taken from that location. The shipping cost will be determined based on which warehouse is shipping out the order (and the distance to your customer). Learn more about setting up your location fulfillments here.
I know this is a lot of information, so please let me know if you have any questions! I’d love to hear more about your current shipping strategy, are you using Shopify Shipping?
