Applied Underwriting Insurance for Work Comp

My agent is wanting to hook me up with this company to save money on my comp rates. I wondered if anyone here is or has used them and how it worked out. There are a couple of bad reviews online that concerns me. I also don't like that they also require that they take over my payroll. I know a lot of people use payroll services but I never have and don't see an advantage for me to do so. The savings could be as high as $20,000 a year so it's tempting, but............. Anyone have anything to offer here?

Was referred to this site. Hmmmmmmmmmmm.

Just doesn't seem that it's worth the risk.

I once had a payroll company carry my work comp. (I now use PayChex, payroll only)

Everything was A-ok..........until I had a claim and got dumped. (Did not matter to them that it was a false claim either)
