Every criterion and weight is set out on How we rank.

The Articles of Organization (Form L010) costs $50 to file with the Arizona Corporation Commission. Each service here adds that fee at cost to its own price.

Publication: a notice runs three times within 60 days unless the statutory agent is in a county of more than 800,000 people, where the Commission posts it instead.

Keeping the company in good order in Arizona after formation
