Contractor license basics by state

“I’ve got a person for you.” Get paid for it.
Your techs see what else a house needs. On the MyHomeService360 network, when your AC tech refers a plumber on the network and the plumbing job sells and gets paid, your company earns a share of the network fee. The business that receives the referral pays nothing for the lead itself, only a network fee after the job is booked and paid. How the referral network works.
