Their pricing looks very good. But very small companies may also want to look into SIMPLE IRAs. They are less flexible in terms of employer contribution options (basically 3% match to a max of $12.5k or 2% unconditional to a max of $5,300) and have lower employee contribution limits ($12.5k) but involve far less paperwork and tend to have considerably lower fees.
