I like that we have an online portal where our employees go in order for themself or others (supervisor) access information regarding paychecks/benefits etc without having any emails going back & forth between us! It's very helpful especially if there is no email correspondence involved with this process of payroll processing as well which helps out alot!! The only thing i dislike at times would maybe could use more user friendly features such has adding new info into existing fields rather than creating another altogether but overall its great so far.
Definitely give em try once they send u free trial code just make sure ur ready because some people are not used too much computers yet hence why sometimes things take time getting set up correctly before users understand how everything works :).
