Hi, i'm trying to put together a business plan for a mobile/home based nail business. In order to work out my pricing as well as looking at the 'going rate' locally i'd like to look at profit per treatment. I therefore need to work out the cost of each treatment. However as i'm new to all this I have no idea how many manicures I can get from a bottle of polish or how many pedicures a scrub will last etc. Can I ask how others work out profit and prices or do you just base on competitors price and hope it covers costs. Many thanks
