I am in Florida and my customer has a tax exempt form becsuse he buys and sells cars for his dealer business. If I do work on one of his vehicles does he have to pay taxes for the work I do? This is the first time I am dealing with this. Has anyone encountered this? So who pays the taxes in the end, the buyer of that car?

So my 11 year old son and I started a small biz. We work only a few jobs a week because of his school and my day job. I figured this would be a good opportunity for him learn business and cars. Anyways when your working a job, sometime things don't go as planned. Especially for the medium to large jobs. When I was doing this for friends for free or on my own vehicles, it wasn't that big of a deal to manage expectations or pick it up the next day. However, when someone is paying me, I fee a need to make everything perfect in the planned time. If I can't get something done with in the time, it may be a week before my son and I can get back out there. I know it is not normal, but my son and I charge a flat rate for a job. Some times I may take extra time teaching my son something or I may go at a slower pace. So I charge a flat rate based on how many hours the "book" says it will take. This way the customer doesn't pay for any extra time it might take to get the job done. Do any of you guys have a plan or policy for how you handle not meeting expectations (Yours or the customers)? Do you refund all or part of their money? Are there other options or ideas. I have a really hard time not meeting expectations and I want to grow past this. So I am curious to hear what you guys do. Especially if your only doing this part time.

Hey guys anyone from Florida.
