Firstbase review

Firstbase sells formation as the entry point to a larger startup back office. The Start package forms a company in Delaware or Wyoming, sets up the EIN on an expedited basis and connects you to banking partners; when we checked, it showed $99 against a $399 list price under an offer that says formation is on us and you pay only your state fee. The recurring costs are what a first-time founder should plan for. Firstbase states that registered agent services are required for incorporation, and its agent costs $299 a year per state. A mailroom address starts at $35 a month or $315 a year, and the Firstbase One bundle is billed yearly at $2,388. That makes sense for a venture-track startup that wants mail, agent, accounting and tax filing under one login. A founder who wants a simple LLC in their own state will pay far less at Bizee, ZenBusiness or Inc Authority.
