Intuit ProSeries

Side-by-Side Comparison
Objective metrics, no spin.
For any business selling in multiple states, e-commerce companies, or when managing sales tax manually becomes unmanageable.
For single-state businesses with simple sales tax or if your ERP already handles sales tax well.
For small-to-medium tax practices, especially those already using QuickBooks. More affordable than UltraTax.
For large firms needing advanced workflow management or if you prepare ultra-complex returns (use Lacerte or UltraTax).
