Store Management is not available in this version of OCTO Ops. The Coming soon badge on this page refers to the Store Management screen itself, not just to this guide — there is no Store Management list, form, or profile you can open in the application yet.
See Warehouse for your stock instead. Store Management still appears in the left navigation under Inventory. Opening its list, its profile, or its create screen shows a page saying it isn't available yet; Inventory is being rebuilt and its screens arrive in later releases.
Who can open it: View to open the list or a store's profile, plus Create for the create screen.
