What to expect

Your email lands with the people who prepare and file the paperwork, not a call center reading a script. We answer during the hours above, and we keep replies plain: what we can do, what it costs, and what happens next. Anything served on your company as its registered agent is treated as urgent and scanned the same business day.

Point us in the right direction

New formation questions

Deciding on a state or entity type, or want to know what's included before you start? Tell us the state you're forming in and we'll walk you through it — no obligation.

An existing filing or order

Checking on a formation in progress, an annual report, or a document in your account? Include the business name and state so we can pull it up right away.

Registered agent & service of process

Anything served on your company is time-sensitive. We scan and upload it the same business day — if you've received legal papers or an official notice, flag it as urgent and reference your business name.

Mail & service of process

Service of process is always scanned and uploaded the same business day, no fee. The first three government mailings per year are scanned free; beyond that, a per-piece scan or shipping fee applies. No tier includes free physical forwarding.

Ready to start instead?

You don't have to email first. Pick your state and see the exact fees on the receipt card —$199 a year, everything included, state fee at cost.
