As a business owner and someone that has specialized in insurance for my full career until retiring early recently, I just wanted to share a story that happened locally and give my advice. A local detailer really messed up someones car around my parts. He left some bad scratches. He is now being sued heavily and is most likely going to lose. Just heard this on the local news tonight. For all of you professional detailers out there, I definately recommend incorporating in either an LLC or an S Corp. keep the liability at a minimum. At the same time use your business to buy your supplies and build your biz credit. Setting up a biz costs very little but might save you a fortune in the long run.
