The Definitive PEO Buyers Guide: 10 Questions to Ask

Choosing a Professional Employer Organization (PEO) is a critical decision. They will employ, pay, insure and support the people representing your company in your most important growth market. Get it right and your US expansion feels straightforward. Get it wrong and you inherit compliance risk, frustrated employees and a cost base nobody budgeted for.

The upside is real. NAPEO research shows that businesses using a PEO grow at more than twice the rate of comparable companies, have 12% lower employee turnover and are 50% less likely to go out of business. Those outcomes depend entirely on choosing a provider that fits.

That is harder than it looks. Headline per-employee-per-month (PEPM) pricing makes PEOs appear easy to compare. In practice, healthcare costs, service models, add-on fees, employer cost treatment and the underlying structure can make two near-identical proposals behave very differently.

These are the ten questions we would ask. Ask them of us too.

PART ONE — WHO YOU ARE DEALING WITH

1. Who employs your people, and who carries the risk?

Start here, because it is the question most buyers never think to ask. The company selling you the service is not always the company providing it. Some providers subcontract the underlying employment to a third-party PEO or in-country partner. Your people end up on someone else's payroll, benefits and tax IDs, with an extra margin layer and an extra step between you and anyone who can fix a problem.

Third-party arrangements are not automatically wrong. They should, however, be disclosed in full, and you should know precisely who is on the hook when something goes wrong.

ASK THEM

• Are you the licensed or registered PEO yourselves, and in which states?

• Which legal entity co-employs our people and whose tax IDs report their payroll?

• Is any part of the employment relationship subcontracted, and to whom?

Our answer.  We employ your people directly, through our own entity, tax IDs and payroll accounts. No middleman or hidden mark-ups. We are the co-employer and hold PEO registrations and licences in the states that require them, and all benefits and insurances are ours and placed with major national carriers.

2. How deep does their US expertise go?

There is a real difference between a global employment business offering a US module and a provider whose expertise is employing people in America. The US is not one employment market, it is fifty overlapping ones, and the things that catch international companies out are usually the things nobody warned them about.

Ask them to talk you through the practical differences between employing someone in California, Texas and New York: separation and final pay rules, hiring practices, leave requirements and non-compete enforceability. You want specifics, not reassurance. Ask something more searching, like the convenience of the employer tax rule. It is precisely the sort of issue a US specialist will have advice and a position on.

Then ask if anyone there has actually done what you are about to do. A provider that has been through a US expansion will already know the questions international companies have, about entity structure, location strategy, employee value proposition (EVP), immigration, and will answer with specifics rather than a process.

ASK THEM

• What do international companies most often get wrong in their first year?

• Who in your business has personally set up or run a US operation?

• Talk us through the practical differences between employing someone in California, Texas and New York.

• Explain your position on the convenience of the employer rule, and if it would apply to us.

Our answer.  US employment is the only thing we do. We went deep in one market because it is the one we had to learn the hard way, and there is no reason you should have to. Our founder took his recruitment business into America fifteen years ago and relocated his family. Since then, we’ve moved clients and their employees from all over the world to the US. In practice that means we advise on and raise potential issues before they cost you time and money rather than after.

3. What does the service model look like once you’ve signed?

Every provider says its service is excellent. The more useful question is how it is delivered. Will you have named people who understand your business and employees, or does each question go into a ticket queue to be picked up by whoever is free? If your management team sits in the UK or Europe, that distinction decides whether a problem takes a couple of hours or a week.

Technology matters too, but for the right reasons. A good platform gives employees self-service and gives you real-time reporting and a clean breakdown of what you spend across payroll, tax and benefits. What it should never be is the reason you cannot reach a person. And test all of this before you buy: how a provider treats you during the sales process is the best evidence of how it will treat you afterwards.

ASK THEM

• Who exactly will we deal with day to day, and what happens when they are on leave?

• Can we contact our team by phone and email, or only through the portal?

• How many clients does your account manager look after?

• Can we see the platform, and what employees can do themselves?

Our answer.  We run a high-touch managed service and are people-led rather than platform-led. You get a dedicated team of in-country experts who learn how your business operates, with teams in both the UK and US so you and your employees reach a person during your own working day. Clients tell us we are proactive and responsive. Our platform is market leading and provides payroll, onboarding, benefits, time-off, HR and more in a single system with real-time visibility of payroll, headcount, and costs, and we will never funnel you into a chatbot or a ticket queue.

PART TWO — WHAT YOU ARE ACTUALLY BUYING

4. Can they scale and flex as your US presence changes?

Most companies get this the wrong way round. They either buy for the business they have today, or they overbuy enterprise infrastructure for their first three hires.

Watch for minimums. Many PEOs require three to five employees, set minimums for benefits, monthly fee floors, or make you commit to headcount growth now which that make the economics unattractive for early hires. Ask what happens in both directions: as you grow, does your unit cost fall, and as your own capability grows, can you take work back in-house and pay less for it?

Ask about structure too. Many companies enter the US on an EOR basis to test the market, then establish an entity and move to PEO. Some run both at once, in different states. If your provider cannot do both, you will be changing provider at precisely the moment you are busiest.

ASK THEM

• What is your minimum headcount or monthly fee? Are there minimums for benefits?

• Does our cost per employee reduce as we grow?

• Can we move between EOR and PEO, or run both, without changing provider or re-onboarding staff?

• Can we change service level as our own team takes more on, and are there any charges for that?

Our answer.  No minimums: launch with one hire, with access to benefits immediately, and pricing that falls as headcount rises. EOR, PEO and AOR sit under one roof, so you can start on EOR to test the market and transition to PEO once your entity is setup or run both simultaneously across different states. You can move between PEO tiers as you mature, from fully Managed support for market entry, stepping down through Complete to Essential as your own team takes more on.

5. What HR support and employment docs are included, and what is extra?

“HR support included” can mean anything from a library of resources to full HR support and advisory. Establish what you are buying.

Somebody has to handle onboarding and I-9 verification, new-hire reporting, posting and notice requirements, leave questions, employee relations and terminations. Somebody needs to issue the paperwork: offer letters, employment agreements, restrictive covenants, invention assignment, handbooks with the correct state addenda.

Price that separately. Having these documents provided independently will typically run to several thousand dollars, and they need revisiting every time you employ in a new state. A provider that supplies that documentation as part of the service is removing a real cost from your first year.

ASK THEM

• What aspects of HR do you do, and which do we do?

• What documentation is included, and how it is kept current as we enter new states?

• Walk us through what happens when we make an offer?

• What triggers an additional HR consulting or document charge?

Our answer.  We offer three service tiers because companies need different things at different stages: Essential for teams with their own HR capability, Complete for guidance and templates, and Managed where we run everything on your behalf. Handbooks, policies and employment documents come as templates kept current through leading industry legal tech. Where you need bespoke drafting or formal advice, we will say so and introduce you to employment counsel we trust.

6. What is their experience and standing in the US expansion ecosystem?

A good US expansion partner should have expertise beyond its own product. Look at the network around the provider. Who do they work with when you need support outside the PEO relationship? Can they introduce reputable immigration specialists, tax advisers, accountants, lawyers and banking providers? Were you referred to them in the first place by someone whose judgement you trust?

Then ask whether they are genuinely connected to the US expansion or international business community and whether they contribute anything useful to it. There is a real difference between publishing generic search-optimised blog posts and running vendor showcases and creating environments where founders and operators can learn from people who have actually built businesses in the US. Look at the events they host, the organisations they partner with, the experts they bring together and the quality of what they produce.

ASK THEM

• Who do you introduce clients to for immigration, tax, banking and legal support, and how were they vetted?

• What do you host or publish, and who actually turns up?

• When was the last time you advised a client something that saved them money?

• Can we speak to a client you have referred into that network?

Our answer.  We spent more than a decade vetting service providers to build a network of partners who understand US and international business and can explain it in a way that makes sense to international founders. We introduce you directly to the right person in the right department every time. In2America House is part of that: bringing founders, investors, advisers and experienced operators together for practical conversations about the real decisions companies face around US expansion.

PART THREE — WHAT IT WILL REALLY COST

7. What will benefits cost and will they win you talent?

For most employers, healthcare will dwarf the administration fee. An apparently inexpensive PEO becomes an expensive one very quickly if its health plans cost more.

Do not accept carrier logos and plan names. Ask for actual premiums, for the plans your people are likely to choose, at every tier: employee only, plus spouse, plus children, family. Then apply the employer contribution you intend to make and multiply by the headcount you expect in six, twelve, eighteen months. That is the number that matters. A small difference in management fee becomes irrelevant next to hundreds of dollars a month per employee in premium.

Then look at breadth. American candidates compare offers on the whole package: medical, dental and vision, life and disability, HSA and FSA, and the retirement plan. If you are new to the market, you also need someone to tell you what competitive looks like for that role, employee type, in that sector.

ASK THEM

• Show us the real premiums by tier and plan.

• What employer contribution do comparable companies make, and how should we structure ours?

• Which ancillary benefits are included, and which are charged separately?

Our answer.  Benefits are customisable: you choose which benefits you want to offer and we walk you through the employer contribution calculation and how you can apply it, then we benchmark it, so you know where your offer sits against the market. Medical, dental, vision, HSA, 401(k) and a broad ancillary range are part of the package rather than a series of upsells.

8. Where do your employment cost savings go, do you ever see them?

Here are two questions you won't know to ask unless you've worked inside US payroll or use a broker.

The first is Section 125. When employees make qualifying pre-tax contributions through a Section 125 benefit plan, typically towards medical premiums, an HSA or an FSA, taxable payroll falls. So does the employer's payroll tax bill. That is real money, every pay period. Ask your provider what happens to it. Some PEOs retain those savings. It is a legitimate model, but it lets a provider advertise an attractive headline fee while quietly recovering margin inside your employment costs.

The second is what happens later in the year. Several employer taxes are capped and stop once an employee passes the annual wage base. So, for a well-paid employee, your genuine employer cost falls sharply partway through the year and, on some taxes, stops altogether. A provider charging a flat blended percentage of payroll for twelve months keeps everything above the real cost, and you will never see it.

ASK THEM

• Do you retain the employer payroll tax saving generated by Section 125 deductions?

• Once an employee passes the FICA or FUTA wage base, do your payroll tax charges stop?

• Are statutory employment costs passed through at actual cost, or at a blended rate?

• Can you show us a charge breakdown that demonstrates it?

Our answer.  We pass Section 125 savings straight back to you through payroll, in the period they arise. We charge the actual cost of employment for each employee in each state rather than a blended rate, which means when an employee hits a wage base cap, our charges stop with it. Employing through us costs you the same in statutory terms as employing directly. Don't only ask providers what they charge. Ask what they keep.

9. Is 401(k) included and what does it cost?

Not all 401(k)s are equal, and "401(k) available" on a proposal tells you very little. Plenty of providers front a basic plan that quietly excludes the things you will want: employer matching, participant loans and hardship withdrawals, or the ability to transfer an existing plan in and roll balances over from previous employers. Those features are often available, but only on an upgraded plan at a higher cost.

Then ask for the entire fee stack: set-up, administration, recordkeeping, per-participant charges, asset-based advisory fees, compliance testing and any transfer fee. Ask the provider to model it at your number of participants and your likely asset balance.

A plan that looks economical at 50 participants can look very different at 5. And this should not be viewed as a nice-to-have in the US: among businesses with 10 to 49 employees, NAPEO finds PEO clients are more than twice as likely to offer a retirement plan as those without one.

ASK THEM

• What is included in the plan as standard, and what sits behind an upgrade?

• What is the total annual cost at our participant count and asset level?

• Which plan provisions can we set ourselves, and which are fixed?

• How does the cost change as our assets and headcount grow?

Our answer.  We offer both a template and custom plan design structure. Our pooled plan is included in your PEO fee at no additional cost with provisions set at plan level. If you want to design your own, including discretionary employer contributions, we can set up a custom plan administered and billed by In2America. That one carries its own fees, and we will quote them upfront rather than after you have signed.

10. What is the true, total, all-in cost?

Finally, the question that consolidates all the others. A low headline PEPM rate rarely tells you what the service will cost. Ask each provider to itemise what sits inside the base fee and what is billed separately, and be specific: implementation, onboarding and offboarding, new state set-up, HR consulting, employment documents, handbooks, time and attendance, off-cycle payroll, 401(k), benefits administration, minimum commitments.

Then insist on a single total cost to employ figure: the full annual cost of employing and supporting your expected US workforce, at today's headcount and at the one you’re planning for. Make sure it includes every benefit you intend to offer, every state you expect to hire in, and every platform module you will need. Same assumptions, every provider. That is the only genuinely like-for-like comparison available to you, and asking for it is informative in itself, because providers with clean pricing produce it quickly.

Be sceptical at both ends of the range. NAPEO puts the return on investment from using a PEO at 27% in cost savings alone, but only when the provider delivers. Rock-bottom rates usually mean a self-service platform, a chatbot and an add-on fee schedule you discover later.

ASK THEM

• What is our total annual cost for our first hires, fully loaded?

• Which of the items above carry an additional charge?

• Is there a platform fee, a minimum headcount or cost, an implementation fee or new state set up cost?

• At what headcount does our PEPM rate drop, and by how much?

Our answer.  No platform fee. No implementation fee. No cost for onboarding or offboarding employees. No cost to add a state or run a special payroll. One bundled management fee per employee per month, which falls as your headcount grows, plus the actual cost of employment in each state. We will model your total cost before you sign, and it will look the same afterwards.

A SCORECARD TO TEST EVERY PROVIDER

We have turned these ten questions into a scorecard: one row per question, what good looks like alongside each, and columns for every provider you are considering. Ask all ten of each one, score them out of five, and weight the rows that matter most to your business. The exercise takes an afternoon and will tell you more than any proposal document.

Get in touch through the contact form and we will send it over.

ONE LAST THOUGHT

Switching PEO later is possible, but genuinely disruptive: new payroll, new platform, new benefits, and a group of American employees wondering what is going on.

If you take one thing from this guide, take this. Compare the total cost of employing your people, not the fee on the front page, and pay close attention to the quality of the people you will be dealing with first thing in the morning or last thing at night if something goes wrong.

Ask the ten questions of every provider on your list, including us. If it would help, send us your headcount, the states you are hiring in and the benefits you want to offer, and we will come back with a total cost to employ figure you can put alongside everyone else's.
