You will need to include the following costs for setting up your waxing business, you may have already had training and have insurance:
Training Costs ( General Body waxing & Intimate waxing for female and male waxing)
Annual Insurance
Couch
Lamp
Trolley
Wax Heaters
Disposables; Gloves/aprons/couch roll/ spatulas/cotton wool pads/strips/wipes/
Wax Products: Waxes/ pre and post wax products
Cleaning products- Wax equipment cleaner/Solvents etc for wax spills/Barbicide
Tweezers/clippers/scissors
I use Salons Direct and Ellisons and they both have a great waxing section which will show you the various options in the range and you can decide the quality you want to use.
Do some reearch with the wax brands there are so many and get a few samples and try them out for yourself.
Good luck
