Clients are mislead and misinformed when they are sold a plan. Small businesses have to cough up tens of thousands of dollars at plan year end in order to stay in compliance with the regulations. They are obviously angry, and many do not have that in their budget. So if you like dealing with angry people that there is nothing you can do for, you will be fine.
Adherence to the regulations are sloppy and often wrong. They have oversold more than their system can handle and more than their allocated staff of compliance people can handle. The focus is on automation, but there is such turnover in their engineering departments, nothing works.
It makes matters worse that they haven't historically focused on hiring people that know about retirement plans. Now that they have shelled out tons of money in IRS penalties they have tried to correct course, sort of. Things are in such a disarray, anyone with a sense of ethics and accountability won't entertain the job opportunity. The experienced people that do take a chance on HI, are either fired for pointing out mistakes or they leave before they are fired. Knowledge and experience are a liability.
Now they have resorted to hiring payroll professionals instead. These people don't know what they don't know.
