How it works

How we deliver, end-to-end.

Four-step path from request to confirmation. State and IRS turnaround varies; our steps run in parallel where possible to compress the timeline.

1

Intake + scope

You tell us what you need through a short intake form (or a call for complex matters). We confirm scope, surface any gating issues (deadlines, missing documents, entity status), and quote any state fees that pass through at cost.

2

Prepare + verify

Our specialists draft the filing, verify entity details against state databases, run internal QA, and route any items needing your sign-off. You see drafts before anything gets submitted.

3

File with the authority

We submit directly to the state Secretary of State, FinCEN, IRS, USPTO, or whichever authority your filing requires. We pay state fees at cost and track the submission identifier in your account.
