ZenBusiness vs CSC (Corporation Service Company): At a Glance
ZenBusiness. ZenBusiness is a modern, online-first registered agent service launched in 2017 and headquartered in Austin, Texas. They built their offering around small-business owners and startups who want a clean dashboard, fast e-document delivery, and predictable pricing. Their California office handles registered-agent service for tens of thousands of LLCs and corporations, and they’re known for transparent flat-rate pricing and strong customer support.
CSC (Corporation Service Company). CSC (Corporation Service Company) is one of the oldest and largest registered-agent providers in the United States — founded in 1899. CSC is the registered agent for a huge share of Fortune 500 companies and major California-licensed corporations, banks, and insurance companies. Their California office is at 2710 Gateway Oaks Drive in Sacramento, where they receive personal service for thousands of represented entities. CSC is the choice when your business needs enterprise-level compliance reliability.

How It Works
You provide the company name and case info
Submit your documents through our intake form. We confirm which entity you’re actually trying to serve and verify their current registered agent on the California Secretary of State’s records — sometimes the agent changes.
We attempt service at the correct agent’s office
For ZenBusiness: Austin, TX (no California physical office for service — process service routes through their California Statutory Agent address). For CSC (Corporation Service Company): 2710 Gateway Oaks Drive, Suite 150N, Sacramento, CA 95833. Service is performed during regular business hours; we cover the agent intake desk directly so the documents go to the right person.
You receive proof of service the same day
After successful service, we generate the appropriate proof of service form (POS-010 for a summons, SUBP-001 for a subpoena, etc.), sign and date it, and email you a digital copy. Hard copies and court filing available on request.
Frequently Asked Questions
Can my company switch from ZenBusiness to CSC (Corporation Service Company) (or vice versa)?
Yes — California allows you to change your registered agent at any time by filing Statement of Information (Form SI-200 for corporations, SI-550 for LLCs) with the Secretary of State. The new agent must consent before you list them. Both providers will help walk you through the change if you’re moving to them; confirm pricing first.
How long does it take to serve papers at ZenBusiness’s California address?
Same day in most cases. We confirm the registered agent address against current SOS records before sending a server, then attempt service during business hours. If our first attempt is unsuccessful (rare at registered-agent offices), we re-attempt the following business day.
What about serving papers at CSC (Corporation Service Company)’s California office?
Same process, same flat fee. Our field servers are familiar with the intake desk at CSC (Corporation Service Company)’s California office and know the staff handling process service. This makes for predictable turnaround.
Which registered agent should I choose for my own business?
That depends on what you need. If you want enterprise-level reliability and have many licensed entities or business locations, larger services like CSC and CT Corporation offer the deepest infrastructure. If you’re a single-LLC small-business owner who values simple flat-rate pricing, services like ZenBusiness, Northwest Registered Agent, or Cogency Global may be a better fit. Either way, we can serve papers on whichever agent your company designates.
Do I need to use a Sacramento process server even if my case is in another county?
If the registered agent’s California office is in Sacramento (like Cogency Global at 1325 J Street, Northwest at 1401 21st Street, or CSC at 2710 Gateway Oaks), yes — the service must be physically delivered to the Sacramento address. Our crew is local to that corridor and serves these offices daily.
What does same-day registered agent service cost?
$85 flat for personal service at any registered agent’s California office, regardless of which agent the company uses. No mileage, no rush surcharge. Proof of service included. Out-of-state subpoena domestication is extra ($200 flat, $300 rush).
