Hi there, info1413.
The option to set multiple price levels of your products and services for your customers isn't available.
In the meantime, you can change the prices on each item when creating transactions.
I've added this reference as your guide when editing items: Add product and service items to QuickBooks Online.
Rest assured, I'll take note of this product suggestion.
Please let me know if you have further questions. Take care!
If you a re a wholesaler, consider having a 3rd party app to manage multi pricelists with multi currencies for your resellers and integrate the app with your QBO account.
