Hi,

The 'Dropshipping' feature in Odoo is primarily activated within the Inventory application. You navigate to Inventory > Configuration > Settings, and then enable the 'Dropshipping' option there. This is because dropshipping is fundamentally a stock management strategy, even though it impacts sales and purchasing processes. Enabling it in Inventory settings makes the necessary dropshipping routes and options available throughout Odoo.
