If a person wants to practice on their own, without working for an employer, which credential should the person get?

Explanation:

If a person wants to try without an employer but by himself, he will need a certification to ensure that he has knowledge and skills to do business. We could consider a licensure in this context, but it's not mandatory, because there are many people who are not business licensure but they started a business with proper certifications to do it.

In addition, certification is defined as the confirmation of skills, abilities, knowledge of an person or organisation to provide a specific service, a certification will accredit to work, and will imply specific credentials.
