South Dakota is a conducive place to start a business. The state has flexible regulations and limited taxes that help new investors get established fast. The workforce is well-educated and the business community supports new investors through mentorship. The business registration guidelines require you to develop a business idea first.

The name you choose should align with the business idea or products/services you will be selling. The name requires a designator such as LLC, LC, Corp., Inc., or Limited. If you decide to start a sole proprietorship, the law requires you to register a Doing Business As (DBA). You may choose to conduct your business operations entirely online. In this case, you have a choice to register a domain name. To make sure no other person is using your name, search and then register it.
