We are currently on Datair and looking at other options. We are looking at Ft Williams (given we use their document & 5500 system), ASC, and possibly Relius (but unlikely given costs). One concern is the processing of huge plans. Currently, we have issues with Datair stalling during busy season when someone is importing or calculating a huge plan. We do not want to relive this. We also would like a program that provides some reconciliation options between the accrued balance on the software and vendor ending balance by participants. Do you have any of these retirement software companies and can you provide pros & cons?
