Why do my product and service list setting options differ from one company to the other?

Let me explain how your product and service list settings differ from one QuickBooks Online company to another, @bushiban-southbu.

Managing product and service features in QuickBooks depends on the items you input and your subscription plan. Creating Inventory is unavailable for Simple Start and Essential plans. If you input different items for different companies, you'll see different items as well. 

If you're referring to something else, I would appreciate it if you could provide a screenshot so I can provide the necessary information.
