"We support all 50 states" isn't the question.
Here's what actually matters when choosing a payroll vendor:
Who registers you in a new state, you or them?
How long does that registration take?
When a state changes withholding rules midyear, do they tell you, or do you find out from a notice?
Reactive systems process the change once you enter it. Proactive partners tell you it's coming.
