Thanks for getting back to the thread, ragenegg. I'll share some details about your ProAdvisor plans and pricing concern.

Yes, you're right. However, there are specific circumstances in which existing QuickBooks Online subscriptions are qualified for firm-billed reductions following the program's introduction. Your clients who already have firm-billed subscriptions will still receive the wholesale discount when ProAdvisor Preferred Pricing debuts on July 15, 2021. The ProAdvisor Preferred Pricing discount will apply to clients whose subscriptions are upgraded, downgraded, or transferred to a new accountant.
