r/AutoShopOwners

Hey all, looking for some guidance as a soon-to-be shop owner. My dads owned the business for 40 years and is rightfully so “stuck in his ways”. What markup do you charge, if any, on parts? And do you always stick with the book price on labor after you’ve given an estimate; Ever go higher than book price if bolts break, or if related unforeseen replacements show up?

I come from a business background, so I am on the “charge it all to the customer” side of thinking but I see him eat so many costs and reduce profit simply out of fear of lawsuits and the “this is how we have to do it” train of thought. Any help is appreciated
