Quick answer
DIY LLC filing is usually the cheapest path if you are comfortable using the state website, preparing your own operating agreement, applying for an EIN, and tracking annual compliance. A service such as ZenBusiness can be worth comparing if you want guided filing, bundled documents, registered agent options, and reminder systems.
The key is separating the unavoidable state fee from optional convenience. A formation service does not remove state fees, annual reports, franchise taxes, or home-state obligations.
| Decision | DIY filing | Guided service |
|---|---|---|
| State filing | You file directly with the state. | The service guides or submits the filing. |
| Total cost | Usually lowest cash cost. | Higher if you buy add-ons or expedited processing. |
| Registered agent | You arrange it yourself. | Often offered during checkout. |
| EIN | Free through the IRS if eligible to apply yourself. | Can be offered as paid help. |
| Best for | Confident founders with simple needs. | Founders who prefer a guided process and reminders. |
When ZenBusiness-style filing can make sense
- You are forming your first LLC and want fewer state-website surprises.
- You need a registered agent and prefer to bundle it during filing.
- You want operating agreement templates and compliance reminders in one workflow.
- You are a non-resident and want extra help understanding the sequence.
When DIY is probably enough
- You know the correct state and official filing portal.
- You are comfortable applying for an EIN yourself.
- You can track annual report and tax deadlines without paid reminders.
- You do not need a bundled registered agent or document package.
Cost trap to avoid
Do not compare a service package price against only the state filing fee. Compare the full first-year stack: state filing, registered agent, first recurring state fee, operating agreement, EIN help, domain, email, and any compliance package that renews later.
