I have an appliance repair business. I charge for labor and parts. I mark up my parts a flat percentage. How do I respond when a customer wants me to breakdown the cost of labor vs parts? Because I know what they are really trying to do is see if they can find the part cheaper on the internet.
I may or may not break it down for them.
“That is the total price for the service”
I also remind them that I will not use parts they provide.
“Ok, pay my diagnostic charge and do whatever you want with those (probably wrong) parts you found on the internet”
