This initial sweep was crucial to understanding the landscape and identifying potential candidates for in-depth analysis.

Here is what we considered:

1. Pricing Analysis

Pricing is a pivotal factor for businesses, particularly for startups and small enterprises operating on tight budgets.

"Affordable and comprehensive service packages can significantly lower the barrier to entry for business formation."

- Delina Yasmeh, J.D./Tax LL.M, Distinguished Expert in Mergers & Acquisitions

Beyond just forming an LLC, we looked for services that offer a holistic business formation and support approach. This includes registered agent services, compliance alerts, and annual report assistance.

Northwest Registered Agent and Bizee had a holistic business formation and support approach. While offering top-tier services, Harbor Compliance had expensive packages and lacked some features.

We scoured customer reviews, feedback, and industry reputation to gauge the reliability of each service.

Established names like LegalZoom naturally stood out with their vast experience and extensive client base. ZenBusiness also had outstanding customer feedback.

No specific company was identified as underperforming in this area.

No, it is not hard to get an LLC in Illinois. You only need to file the Articles of Organization with the Secretary of State and pay the $150 filing fee.
