I doubt this is a response to ADP; ADP is a horrible product, and Zenefits knew they could make a better solution (like ZenPayroll&#x2F;Gusto). They&#x27;ve probably been working on this for a year, to be honest, given the requirements for payroll providers and syncing with the IRS&#x2F;etc.<p>What&#x27;s more interesting is that the payroll is free <i>only if</i> the company manages everything else HR related in Zenefits. Talk about lock-in.
