Keep in mind that you’re going to want to type in different versions of your business name to make sure that you’re not duplicating someone else’s business name. This is also important for marketing purposes, as you do not want customers confusing your business with someone else’s company!
Step 2: Decide what kind of business structure you want.
For the purposes of continuity and clarity, this article will focus on starting a single-member LLC.
Step 3: Determine your Registered Agent
If you are filing by yourself as the sole owner of your business, you will only need to worry about your own personal information. You will be the “registered agent” – this is the person who will handle all legal aspects of your business.

Step 5: Complete the online filing process.
You should only need to file once with your state, so once you’re done providing your information, make sure you pay for your company’s registration successfully.
Step 6: Wait for the Secretary of State to approve your filing.
If something goes wrong during the process, the state will reach out to you to correct any issues.
Step 7: Keep your documents safe!
Store your digital files in multiple locations on your computer, in the cloud, and print a physical copy of each to ensure that you don’t lose them. After a certain amount of time, you won’t be able to access your documents any more, and will have to request copies if you lose yours.
