Tax Planning Software - Your Thoughts?

Solo practicing CPA here. Mostly focus on income tax prep. 80/20 split individual/PTE.

I get asked about planning way too much and do way too little of it. I haven't looked into planning software for about 2 years at this point.

The last demo I did was with Corvee, and they quoted me at $10,000 for federal-only and $15,000 for federal+state.

What is everyone else using? Benefits/shortcomings? cost?

TIA!
