Cross-docking is the process of sending products that are received directly to the customers, without making them enter the stock. The trucks are simply unloaded in a *Cross-Dock* area in order to reorganize products and load another truck.
For more information on how to organize your warehouse, read our blog: `What is cross-docking and is it for me? <https://www.odoo.com/blog/business-hacks-1/post/what-is-cross-docking-and-is-it-for-me-270>`__
Create the product that uses the *Cross-Dock Route* and then, in the inventory tab, select the routes *Buy* and *Cross-Dock*. Now, in the purchase tab, specify the vendor to who you buy the product and set a price for it.
Once done, create a sale order for the product and confirm it. Odoo will automatically create two transfers which will be linked to the sale order. The first one is the transfer from the *Input Location* to the *Output Location*, corresponding to the move of the product in the *Cross-Dock* area. The second one is the delivery order from the *Output Location* to your *Customer Location. Both are in state *Waiting Another Operation* because we still need to order the product to our supplier.
Now, go to the *Purchase* app. There, you will find the purchase order that has been automatically triggered by the system. Validate it and receive the products in the *Input Location*.
When the products have been received from the supplier, you can go back to your initial sale order and validate the internal transfer from *Input* to *Output*.
