What PEO cost bloat looks like
The PEO admin fee is easy to overpay because it's quoted three different ways and buried in an invoice built around payroll, not the fee.
- An admin fee quoted as a percent of payroll that quietly grows every time you give raises or add headcount — same service, bigger bill.
- A per-employee-per-month (PEPM) fee that still bills for terminated or seasonal employees who left the roster cycles ago.
- A blended “bundled rate” that mixes the admin fee with benefits and workers' comp, so you can't see what the PEO itself charges.
- Add-on module fees — onboarding, performance, time tracking, an HR hotline — stacked on top of a base fee you thought was all-in.
- An admin fee that never dropped at scale even after your headcount doubled, when most PEO pricing tiers down with size.
- Markup baked into benefits administration that's never broken out as a line you can question.
How Bloatweiler trims your PEO cost
Human-reviewed, evidence-first.
We read the actual invoice
Send your latest full PEO invoice plus the service agreement. A human — not a bot — separates pass-through payroll and taxes from the real admin fee, whether it's a percent of payroll or PEPM.
We benchmark the admin fee
We re-state the fee on a per-employee basis, compare it to current market PEPM ranges for your headcount, and flag any add-on modules or unexplained markup with evidence from your own statement.
You approve every move
Findings come back as Savings Opportunity Cards — a fee renegotiation, dropping unused modules, or repricing at your real headcount. Nothing is contacted or changed without your sign-off, and we never advise on your benefits.
An example, not a promise
Real findings ship with evidence, a range, and a confidence level. Never guaranteed. The card below is an invented example.
Percent-of-payroll fee that grew with every raise
A 30-person company was billed an admin fee at a percent of total payroll. As wages rose over two years, the fee climbed with them even though the PEO's actual work — runs, filings, support — hadn't changed.
Evidence: PEO invoices show the admin line as a fixed percent of gross payroll; re-stated on a PEPM basis the effective fee had drifted well above current per-employee market ranges for a 30-person group.

Next step (you approve): Open a conversation about converting to a flat PEPM fee or repricing the percent — only after you approve, and with no change to your benefits.
PEO pricing models: percent of payroll vs PEPM
PEO pricing usually comes in one of two shapes. The first is a percent of payroll — simple to quote, but it ties the admin fee to your wages, so the fee rises every time you give raises or add a higher-paid hire, even though the PEO's workload barely moves. The second is per-employee-per-month (PEPM), a flat dollar amount per active employee that's far easier to predict and to benchmark against the market.
Neither model is automatically cheaper — it depends on your average wage and headcount. The trap is that a percent-of-payroll fee can drift well above what the same service would cost on a PEPM basis without anyone re-checking. Restating your fee per employee is the fastest way to see whether your PEO cost is fair. We do that read as your free Bloat Audit, and we focus only on the admin fee — never your benefits or coverage.
PEO vs payroll, and what HR outsourcing cost should be transparent about
A standalone payroll provider runs payroll and files taxes. A PEO does that and co-employs your staff so it can bundle benefits, HR support, and compliance — which is genuinely useful, but it also makes the bill harder to read. The single number you should be able to see clearly is the admin fee the PEO earns, separate from the pass-through payroll, taxes, and any benefits premiums.
Good HR outsourcing cost is transparent: you can point to the admin fee, understand whether it's percent-of-payroll or PEPM, and see what each add-on module costs. If your PEO can't break that out, that opacity is usually where the bloat lives. We help you read it and weigh exit or renegotiation considerations — contract notice periods, run-out timing, year-end transitions — without ever pitching you a different benefits plan.
Questions, sniffed out
How is PEO cost actually calculated?
PEO cost has two parts: the pass-through (your employees' wages, payroll taxes, and any benefits premiums) and the admin fee the PEO earns for its service. That admin fee is usually charged either as a percent of payroll or as a flat per-employee-per-month (PEPM) amount. Bloatweiler reads your invoice to separate the two and benchmark the fee.
Is percent of payroll or PEPM cheaper for a PEO?
It depends on your average wage and headcount — neither is automatically cheaper. Percent-of-payroll fees grow with raises and higher-paid hires; PEPM stays flat per active employee and is easier to predict. We restate your fee on a per-employee basis so you can compare apples to apples. No guaranteed savings.
Do you change my PEO or my employee benefits?
No. We review the admin fee for transparency and fair pricing, and we never advise on, recommend, or change your benefits, insurance, or coverage — that stays with you and your licensed professionals. If a fee renegotiation or switch makes sense, we show you the options and you approve before anything happens.
Is the PEO audit really free?
Your first Bloat Audit is free and takes about two minutes to start. If we find the admin fee is worth renegotiating, we'll explain the options — including how we're compensated and any disclosures — before anything changes on your account. No guaranteed savings.
What should I check before leaving a PEO?
Look at the contract's notice period, any tax-wage-base reset from switching co-employers mid-year, and run-out timing for benefits and filings. We'll help you read those considerations from your own agreement so a switch is a clear-eyed decision — but the call is always yours.
