So can anyone explain why my post on this subject was deleted? I can’t post about it but AGRR can write articles in detail about it????

An interesting question... and hopefully AGRR will address it, here on this forum, so that others can understand as well!

Direct billing is a viable option for many glass shops, but not the only option to get paid more than the insurance companies are calling "Reasonable and Customary". Many shops bill directly and then sue the insurances company after they have been not paid or short paid. Some shops go to Arbitration. Some shops invoke the appraisal provision in the policy.

Direct Billing simply means that the shop is billing the insurance companies directly and not billing through any of the third party administrators such as Safelite, Lynx services or HSG.
However, many shops bill through the TPA's and still pursue additional payments after getting short paid. The state in which the glass shop operates has a lot to do with what option is best.

For example, in Florida most shops choose litigation when they are short paid because of the statute that allows the lawyer to collect their fees from the insurance company when they prevail. In Minnesota, many shops have been very successful with arbitration. In other states
Appraisal is a good option. Whether the shop bills direct or through the TPA, when they are short paid they have invoked the appraisal clause and reached an amicable resolution.

The process has a bit of a learning curve, but can be well worth it. A valid assignment is critical regardless of which option you choose.
