Link warehouses deliberately, preserve payment reservations and review invoice dispatch and stock-cost recognition.
Inventory holds your stock#
In a business workspace, stock lives in Inventory. Ecommerce and Point of Sale both need it, and adding either app adds Inventory with a main warehouse, already set up from your business details.
Inventory can't be removed while an app uses it. Saved links and history stay protected. Invoicing connects for dispatch notes and double-entry Accounting connects for stock costs, when you turn those connections on.
Keep the active workspace, actual business requirements and current setup summary in view. A guide explains a choice; it does not make that choice for you.
