Premium Audit Companies

[melenajade]

To all brokers and agents,

I'm a telephone auditor. I verify payroll and sales for work comp and general liability policies in PA and CA for two different vendors. I really like it, the freedom and structure the position brings.
I'm interested in learning more about how much carriers pay for audits to verify payroll and sales. Is it a % of premium? A flat rate? Does it vary on the size of the insured's company or policy?
What companies are out there that offer telephone or virtual premium audits?
What are some of the best premium auditing companies you've worked with?
What are some of the worst?

I'm new, Hi and thanks for helping me learn!
