I have started and aborted a couple for our group, but now have one up and running for 2.5 years.  We offer a true pay as you go based on client self reporting with annual audit.  All but four hazard classes are eligible and commission is good. I offer it to any licensed agent.  Shoot me an email at bob@joewestins.com for details.

The premium is paid on a monthly report and pay structure.  The client reports payroll at the end of each month using a net rate worksheet.  The carrier runs an EFT 48 hours after receipt of the report.  No down payment, no audit surprises, and cash flow is eased.  Only four class codes are unavailable.  Send me an email bob@joewestins.com and I'll reply with more detail.
