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.
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.
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.
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.
Confirmation + vault
Stamped certificate, IRS notice, or filing receipt arrives in your SOC 2 encrypted document vault the moment we receive it. Next filing deadline auto-added to your compliance calendar where applicable.
Built on the same infrastructure used by 220,000+ businesses.
SOC 2 Type II audited
Independent annual security audit covering access control, change management, incident response, and data handling. Current report on request.
All 51 US jurisdictions
Every state plus DC plus Puerto Rico - direct filings, not third-party reseller. We hold registered-agent qualifications in every state we operate.
Deadline guarantee
If we miss a filing deadline on a service you pay us to manage, we pay the state penalty. Specific to each plan and the filings it includes.
4.9 from 8,200+ verified reviews
Independently verified by Trustpilot + Google + our own NPS infrastructure. Customer success team within reach by email, chat, or phone.
60-day money-back promise
Change your mind in the first 60 days and we refund our service fee in full. State filing fees pass through at cost and are non-refundable once paid to the state.
E&O insured
Errors and omissions coverage protects you from service errors. Carrier and certificate available on request for enterprise clients.
