Should I sue the person or the business?

I have a situation in which someone performed body work on my truck and did not complete it after I paid him. I would like to take this person to small claims court. He technically has a registered business but he currently works out of other people’s shops and his house. He deals primarily in cash so I doubt he claims much on either himself or the business. The receipt he gave me shows his business name on it.

Who would it be better to sue, him or his business?
