Exactly. To tell you the truth I think that if we could ever find a PEO that would let us do everything related to the admin for our plans, that would be the home run scenario for this stuff. Because if you're the PEO, you're already running the payroll, the data is yours, etc. And of course you're not a 316 you're the actual administrator.
Anyway, obviously finding a PEO who would let me do that might be harder then finding the Lost Ark. And yes PEO's are expensive but there is a clear value proposition there, where I think this 3(16) stuff just does not add enough value to justify the extra fees that they charge.
But that's just me.
