QuickBooks ProAdvisor Deluxe Software Bundle goes from $350/yr to $450/yr for renewals beginning 9/3/2019. QuickBooks Desktop Accountant (which I think is the same thing minus the ProAdvisor training/certification benefits) goes from $400 to $500. (amounts rounded).
So I will get one more renewal at the old price. Still not too bad, considering I used to pay $549 just to get Enterprise/POS/Mac versions which I never really used (just one billable job using Enterprise).
Back when I started my practice, being an Advanced Certified ProAdvisor was worth something in terms of Find-A-ProAdvisor listing and credibility, but now they've discontinued the program, and I imagine Desktop ProAdvisor isn't far behind (it's already not worth as much as 3-4 years ago). While I still need the current version of QB desktop each year, plus support access and accountant features, I'm not dependent on QB for marketing to new clients.
