Contender One
ADP TotalSource is the PEO arm of ADP, one of the largest payroll and HR technology companies in the world, and it positions itself as among the largest certified PEOs by worksite employees. Its structural advantage is the ecosystem: TotalSource sits inside the broader ADP stack, so payroll technology, HR tools, and reporting come from the same vendor that already runs payroll for a huge share of American businesses. Per its published model, TotalSource is a co-employment arrangement: ADP becomes the employer of record for tax and benefits purposes and your team moves onto ADP-sponsored benefits plans.
That scale cuts both ways. Buyers who want one giant vendor for payroll technology, benefits, workers compensation, and HR support get exactly that. Buyers who want a named team that knows their company sometimes find that scale feels like scale. Pricing is quote-gated: you provide a census and go through a sales process to learn what it costs. Certification status is verifiable on the IRS CPEO registry.
Contender Two
Insperity has been in the PEO business for decades, and its published positioning is built around the human layer: dedicated service teams, HR specialists assigned to your account, and hands-on guidance rather than a portal and a phone tree. Like TotalSource, the Insperity model is co-employment, with Insperity-sponsored benefits plans and Insperity as the employer of record for tax purposes. Companies that choose Insperity over larger rivals usually cite the service reputation as the deciding factor.
The tradeoff is the mirror image of the ADP pitch. Insperity does not bring the same sprawling technology ecosystem; its platform exists to serve the PEO relationship, not the other way around. And service intensity is priced in: Insperity is widely regarded as a premium option, though like TotalSource it publishes no pricing and quotes each company individually. If you want to know what either costs, plan on two sales processes and a spreadsheet.

How to Actually Decide
Lean TotalSource. The whole pitch is ecosystem continuity: same vendor, connected technology, benefits and workers compensation folded in. Moving to Insperity would mean adding a vendor, not consolidating one.
Lean Insperity. Its published model is built around dedicated service teams and hands-on guidance. If your last HR vendor experience felt like a ticket queue, that is the pain Insperity prices against.
Pause before picking either. Both models replace your benefits plans and take employer of record status, and both tend to fit best at scale. Read a model comparison like PEO vs HR outsourcing before you sit through two sales cycles.

The Referee's Close
If co-employment is what you want, pick from these two and negotiate hard: they are both credible, certified operators. But notice what both quotes will have in common. Your company hands over employer of record status, your benefits plans get replaced by theirs, and the price arrives only after a sales process. If what you actually want is the HR expertise without any of that, you are shopping the wrong model, and the honest move is to compare PEO vs HR outsourcing before comparing PEO logos.
That second model is what BEG sells. BEG HR outsourcing, powered by isolved, puts certified HR professionals on your handbook, compliance, leave administration, and manager questions while you stay the employer and your benefits stay yours. No co-employment, no benefits takeover, and no quote gate: answer six questions and your estimate appears on screen in about 90 seconds.

Questions
Both market themselves as IRS-certified PEOs, which you can verify on the IRS CPEO public registry. Certification covers federal employment tax responsibility; it does not grade service quality, so the decision still comes down to model fit.
Under both published models, the PEO becomes the employer of record for tax and benefits purposes while you direct the day-to-day work. Your staff appear under the PEO for payroll taxes, and benefits typically move onto PEO-sponsored plans.
Neither publishes pricing. Both quote per company based on headcount, payroll, state mix, and benefits selections, so the only honest answer is to get both quotes on the same census and compare the all-in administrative fee plus benefits costs line by line.
The core value of both models is PEO-sponsored master benefits plans, so in the typical arrangement your existing plans are replaced. If keeping your own plans and broker matters to you, that is a signal to compare the PEO model itself against HR outsourcing before comparing vendors.
BEG is not a PEO and does not compete on co-employment. If you want certified HR professionals handling compliance, handbooks, and manager support while you stay the employer and keep your own benefits, BEG HR outsourcing, powered by isolved, is the alternative model, with an instant on-screen estimate instead of a sales quote.
