It’s a tie. Here’s why: ADP and Gusto target two different customer bases in terms of benefits administration.
ADP caters to more mature, midsize companies that have already established their benefits plans. By comparison, Gusto is oriented towards smaller businesses whose benefits plans are still in flux or perhaps not even set up yet at all.
So in terms of benefits administration, the right vendor depends on whether the company has a benefits package it’s happy with (go with ADP) or is just starting to put one together (go with Gusto).
