[Dependable Dave]

SGC and LYNX/Metryx, plus other smaller operators, are collectively known as "The Network". They do the billing chores and job assignments for the insurance companies. It might be convenient for you to be a member because you might get some jobs the easy way.

Many techs do not use the networks and may not even do insurance jobs. They charge cash and let the customer deal with a refund from the insurance company. Sometimes the networks are a pain in the neck, or other parts. They have, in my opinion, a long way to go in the communications department.

In my case, I am signed up with both SGC and LYNX and take what they send me. I don't depend on them to make a living. There are a few techs who I've met who, in the past anyway, relied solely on the networks. With State Farm pulling out of the mix, that might be a tougher way to go for them.

My advice, if you want it, would be to build your business in all aspects of the industry: Insurance, cash jobs, and fleets. Over time you might migrate toward one of those or more, and maybe eliminate one or more.
