    Justworks

    Justworks is a convenient all-in-one solution that Owners, HR, and business leaders love to work with. Unlike big box software, Justworks says it all in their name by putting together a beautiful working layout that neatly categorizes what is important for employers and employees. Starting with entering employee data, Justworks lets the individual enter his or her own information directly from the app, removing the need for traditional pen-and-paper messes and confusion. They can also set up autopay and receive direct messaging when scheduled payments are delivered. Admins can set up and manage benefits, such as Gym Memberships, Healthcare, and commuter benefits. The end of the year reconciliation is just as easy to process, as it keeps records current for each employee or contractors to facilitate W-4s and 1099 delivery. Justworks makes tedious administration tasks just work.
    Starting Price: $39 per user per month
