| TL;DR: When companies outsource HR, it usually breaks down because no single person owns it, and it only gets heavier as headcount grows. “HR outsourcing” gets used as a catch-all, but PEOs, EORs, staffing agencies, and managed HR support each solve a different problem and come with different trade-offs. The fix isn’t picking the biggest or most well-known option. It’s matching the model to the actual problem you have. |

It's 6:40 pm, and you're filling out an I-9 for your third new hire this quarter, because nobody else will. That new hire's laptop request has been stuck in an IT queue for four days. The handbook still says "team of 12" on the cover. You stopped counting at 30.
You didn't build an HR department because you didn't think you'd need one yet. Ten people, you can track it all in your head. Thirty, and suddenly you're the one who remembers who's on PIP, who hasn't finished onboarding paperwork, and whose benefits enrollment window closes Friday. None of this is hard, exactly. It's just that nobody owns the cadence, so it all lands on whoever's still in the building.
Sometimes the fix is smaller than it looks. If the real gap is that nobody's executing the recurring stuff, you can hire an HR virtual assistant to own that cadence. When you outsource HR this way, no new legal structure is required.
What Outsourcing Your HR Actually Covers
Before comparing providers, it helps to know what's actually being outsourced, since the term covers four distinct categories that don't all carry the same stakes.
HR admin vs legal counsel
These get confused constantly, but they're not the same function. Admin keeps your records and processes current. Counsel makes the legal call. Updating the employee handbook when a policy changes is admin. Whereas deciding if that policy is actually compliant with current employment law is legal. Outsourced HR admin isn't a substitute for legal counsel, and it shouldn't be sold to you as one.
Recruiting coordination
Talent shortages remain one of the biggest barriers to growth, productivity, and innovation. Some of that difficulty is sourcing, finding people with the right skills in the first place. But a chunk of it is just logistics: candidates going quiet because nobody scheduled the next round fast enough.
Recruiting coordination covers scheduling candidate calls, coordinating interviews across hiring managers' calendars, and keeping the pipeline moving so people don't fall out of the process between stages. It's explicitly not sourcing candidates, and it's not making the hiring decision. It's the connective tissue that keeps a good pipeline from leaking.
Onboarding admin
Once someone accepts, onboarding admin is what keeps the first weeks from becoming a scramble: preparing onboarding documents, updating HRIS records, and tracking which paperwork is submitted versus outstanding. It's also what keeps employee files centralized in one system instead of scattered across email threads and someone's downloads folder.
Policy and records upkeep
This is the least visible category, and the one that matters most when something does go wrong. Keeping HR documents and policy updates logged and filed doesn't feel urgent when nothing's on fire. But it's exactly what your actual counsel or an auditor needs to be usable. A handbook nobody's touched in two years, or a records system where nobody can say when a policy last changed, isn't a legal problem yet. It becomes one the moment someone asks.
Comparing HR Outsourcing Models
Now that you know what the underlying work actually involves, the question becomes who should be doing it. Here's how the five common options stack up, and where each one hits its limit.

AI/HR software
This can generate offer letters, flag a missing field on an I-9, or send a reminder email. What it can't do is notice when a new hire goes quiet after that reminder, or catch that a hiring pipeline has stalled for a week. The tool helps, but it isn't the whole answer: McKinsey's 2025 State of AI survey found 88% of organizations regularly use AI in at least one business function, yet only 6% see real, measurable results from it. The software can create the paperwork. Someone still has to notice when it doesn't get finished.
PEO
A PEO (professional employer organization) puts you into a co-employment arrangement; the PEO becomes a legal co-employer, giving you access to group-rate benefits you couldn't get alone. It's the heaviest commitment on this list, and the hardest to unwind later.
EOR
An EOR (employer of record) solves one specific problem: legally employing someone in a state or country where you don't have an entity. Outside of that specific use case, it's not the right tool.
Staffing Agency
These are staffing agencies that fill a role, task by task. Once someone's placed, ongoing oversight, their performance, their paperwork, their file: all of it lands back on you. It works best for short-term or trial hires, not something you need running long-term.
Managed HR Support
This is the only model where you keep your own entity and the outsourcing is of the recurring admin itself. Worth being direct about what this isn't: it's not a compliance or legal service. It doesn't tell you whether a policy holds up legally. It's admin, done consistently, by someone whose job is to not let it slip: the right fit if you want to keep your entity and just get the grind off your desk.
Quick Comparison Table
| Model | What you get | Cost/Commitment | Oversight | Best for |
|---|---|---|---|---|
| AI/HR software | Templates, reminders, flagged fields | Low cost, low commitment | Entirely on you | Reducing manual data entry |
| PEO | Co-employment, group benefits | High cost, hardest to unwind | Shared, but structurally tied to PEO | Wanting big-company benefits, less compliance risk |
| EOR | Legal employment abroad or out-of-state | Per-employee, easy to scale down | On the EOR for that employee | Hiring 1-10 people where you have no entity |
| Staffing Agency | A filled role | Placement fee, low ongoing cost | Back on you after placement | Short-term or trial hires |
| Managed HR Support | Recurring admin executed | Flat monthly, no long-term lock-in | Stays off you, day-to-day | Keeping your entity, offloading the grind |
What Ongoing Coverage Actually Looks Like
Task-based help, staffing agencies, freelance HR help, works like a menu: you decide what needs doing and when, and you're the one who has to remember to ask. Oversight never really leaves your desk.
Ongoing managed support works differently. Onboarding starts because someone was hired, not because you remembered to flag it to somebody. That's the actual difference, not more effort, not smarter tooling, but a process that runs whether or not you're the one watching it.
Which goes back to where this started: the reason admin slips isn't that the work is hard. It's that nobody owns the cadence. Every model above solves a different piece of that. Only one of them solves the ownership problem directly.
Data Security and Remote HR Support
HR outsourcing services also means outsourcing access to sensitive employee data, so before choosing who handles it, it's worth knowing what real protection looks like versus what just sounds reassuring.
Handing HR admin to someone outside your walls means handing over SSNs, bank details, medical information tied to leave requests, and immigration documents. Before that happens, it's worth knowing what actually protects that data and what just sounds like it does.
ISO 27001 and SOC 2 are independently audited standards. A third party has actually checked the provider's security controls and signed off on them. That's different from a vendor simply telling you they take security seriously. If a provider can't point to one of these certifications, or something equivalent, that's worth asking about directly.
An NDA is not a security measure. It's a legal agreement about what happens after a leak, not a control that prevents one. A provider can sign an NDA and still store your employee files in a shared folder with no access controls at all.
Access tiers matter more than most people think to ask about. There's a real difference between someone who can view records to do their job (checking whether onboarding paperwork is complete) and someone who can approve or change something with legal weight (a benefits election, a termination date, a pay rate). Ask who sits in each tier, and whether that's actually enforced in the system or just written in a policy doc somewhere.
Getting HR Support Through Wing
Wing's model pairs one dedicated HR Virtual Assistant with a Customer Success Manager who provides ongoing oversight, so the coverage doesn't rest entirely on your visibility into the day-to-day. The assistant works inside the tools you already use, not a parallel system you have to maintain.
- ISO 27001 compliant and SOC 2 certified, with NDAs and role-based access controls on every account
- Works inside your existing HRIS: candidate scheduling in Greenhouse, records updates in BambooHR, payroll inputs in Gusto, compliance documents in Notion
- Free replacement coverage if the assistant isn't the right fit, plus supervision from Wing's Team Captains and Supervisors on top of the dedicated CSM
Given that 69% of U.S. employers report difficulty finding skilled talent, the coordination layer around hiring, keeping candidates warm between rounds, and making sure interviews actually get scheduled matters more than ever. A stalled pipeline compounds an already hard hiring market.
Pricing:
- Part-time: $799/month (80 hours)
- Full-time: $1,199/month (160 hours), recommended for most people-ops workloads

FAQ
Do I get to meet my HR assistant before they start?
Yes. Wing's process starts with a call to go over your requirements, then shortlists candidates for your review before you interview and assess them yourself. Your assistant only joins once you've confirmed they're the right fit, and you can be as involved or hands-off in that selection process as you prefer.
What happens if my HR assistant is out or leaves?
You're not left covering the gap yourself. Wing provides free replacements, and your assistant is backed by a Customer Success Manager along with Team Captains and Supervisors who maintain visibility into the account, so continuity doesn't depend on one person never being unavailable.
We tried a general VA for HR before, and it didn't work. Why would this be different?
A general VA is usually handling HR as one of several unrelated tasks, with no HR-specific tooling and no oversight layer built around HR workflows specifically. Wing's HR assistants work inside HR systems (Greenhouse, BambooHR, Gusto, Notion) from day one, and they're supervised with HR admin quality in mind, not just task completion in general. The difference isn't the person; it's the structure around them.
