ADP TotalSource vs Justworks PEO: Which Fits?
Choose ADP TotalSource when your company is large enough, or your compliance needs complex enough, to justify a dedicated account manager and enterprise-grade tooling. Choose Justworks when you want the simplest possible on-ramp to co-employment with a lower entry price and a self-service platform your team can learn in an afternoon.
What you need to know
Both are established PEOs that co-employ your staff, process payroll, and give you benefit plans beyond your individual headcount. The meaningful differences are price, compliance depth, support model, and platform feel. ADP TotalSource is the heavyweight built for scale and regulatory complexity; Justworks is the product-first option built for speed and simplicity.

What each is good at
ADP TotalSource earns its keep the moment regulatory exposure becomes the thing keeping your HR leader up at night. The extensive compliance toolkit, dedicated account manager, and enterprise-grade reporting line up with the needs of a 50-to-500-person company that operates across states or in heavily regulated industries. You are buying a service relationship, not just software.
Justworks wins on friction. The interface is simpler, the entry cost is lower, and the built-in employee self-service portal means your people can handle most day-to-day needs without calling anyone. That is precisely why startups and growing midsize firms that value speed choose it, even when a heavier option would technically work.

How to read the price table
The figures above are published benchmarks, not quotes. The base service fee and per-run payroll charge are the easy lines; the lines that actually decide a comparison are benefits pricing and workers comp markup, both of which depend on your headcount, states and loss history. Always ask each provider for a full fee schedule that separates administration from benefits and comp before you compare.
Which way to go
If you have no in-house compliance bench and your main goal is standing up payroll and benefits fast for a small, multi-state team, Justworks is usually the cleaner answer. If your team is larger, your risk profile is complex, and you want a named human plus tooling you can lean on when a filing or an audit goes sideways, ADP TotalSource justifies its higher price.

Is Justworks cheaper than ADP TotalSource?
Historically, yes. Reported benchmarks put Justworks around $900 to $1,300 per employee per year versus ADP TotalSource at $1,200 to $1,800, with lower payroll-run fees too. Quote both for your exact headcount, since benefits and comp change the real total.

Which PEO is better for a 50 to 100 employee company?
It depends on appetite for compliance support. Firms of that size facing complex multi-state or regulatory needs often prefer ADP TotalSource's tooling; teams that prize a simple interface and faster onboarding often prefer Justworks.
