This question comes up often, especially as companies expand across states and regions, add part-time or project-based roles, and ask HR teams to support more with less: Should we be using an EOR, PEO, or staffing agency?
The employment model that worked when your team was centralized and mostly full-time may not be the right fit anymore, and choosing the wrong one can create real friction in compliance, cost, and control.
We recently hosted a webinar on how these three models actually differ, and when each one makes sense. You can check out the full recording here, or keep reading for a recap.
A staffing agency recruits and employs workers on your behalf and then places them with your company. They handle sourcing and onboarding, and in many cases, day-to-day scheduling and oversight. This works well for last-minute or seasonal coverage, short-term defined roles, or situations where you want to fully hand off hiring for a narrow need.
The trade-offs can be real, though. Agency markups increase cost per worker, visibility into performance and workforce data tends to be limited, and you have less say in who gets hired and how they’re managed. For companies building a flexible team over time, a staffing agency tends to be more of a patch than a foundation.
A professional employer organization (PEO) co-employs your workforce. You hire the workers, but the PEO takes on HR administration: payroll, benefits, and certain compliance functions. It’s a practical model if your team is mostly full-time and permanent, if you’re operating in one or a few locations, and if your main goal is offloading HR admin (rather than restructuring how you hire).
The catch is that you still carry employment responsibility, and PEOs aren’t built for contingent, part-time, or project-based work. Compliance across multiple states or countries adds complexity the model wasn’t designed to handle.
PEOs do what they’re built to do well, but if your workforce is flexible and distributed, they’re solving a different problem than the one you have.
An employer of record (EOR) legally employs workers on your behalf while you maintain control over day-to-day operations: who to hire, what to pay, how to schedule, and how performance is managed.
The EOR owns the employment infrastructure—payroll, tax compliance, benefits, workers’ compensation, and employment-related risk—while you run the team.
This model fits best when you have workers across multiple states or countries; your workforce includes part-time, hourly, or project-based roles; and you need to scale without building local entities or deep compliance expertise in every market. It’s why more companies with flexible teams are moving in this direction—the employment complexity is handled while the operational decisions stay with you.
One thing worth noting is that not all EORs offer the same thing. Some function essentially as payroll providers: i.e., they handle the employment paperwork but don’t give you much visibility beyond that.
If you’re managing a distributed field team across dozens of locations, that gap can show up quickly, and you’re left piecing together scheduling, time-tracking, and reporting from other tools.
Others pair employment services with workforce management software, giving HR and operations a real-time view of who’s working (and where) and how performance tracks over time. For teams managing at scale, that difference is significant.
| Staffing Agency | PEO | EOR | |
| Who employs workers? | The agency | You (co-employment) | The EOR |
| Main focus | Recruiting, placement, short-term coverage | HR admin for full-time staff | Employment infrastructure for flexible, distributed teams |
| Best for | Temporary or seasonal needs | Centralized, full-time teams | Contingent, part-time, multi-location workforces |
| Key trade-off | Higher cost, limited visibility and control | You keep employment risk; not built for flexible work | You manage day-to-day; need strong workforce tools for full visibility |
At a certain point, the model you choose stops being just an HR decision and starts being an operational one. The right fit depends on how flexible your workforce actually is, how many locations you’re managing, how fast you need to scale, and how much employment and compliance complexity you’re carrying.
For short-term or seasonal labor, a staffing agency may be the right call. For a traditional full-time team where HR admin is the main burden, a PEO can work well. For a flexible, distributed workforce with real compliance exposure—especially across states or into Canada—an EOR is usually the better foundation.
Essentially, there’s really no one-size-fits-all employment model. But if you’re looking to build a flexible, scalable workforce, an EOR is typically going to provide your best foundation.
AllWork serves as the EOR for W-2 workers across the U.S. and Canada, and as agent of record for 1099 independent contractors—covering payroll, tax withholding, benefits administration, and compliance with federal and state/provincial labor laws. The platform also handles onboarding, scheduling, time and attendance tracking, and reporting, so the employment layer and the operational layer live in one place rather than across multiple vendors.
For companies managing flexible field teams, brand ambassadors, or contingent workers at scale, that combination is what makes it practical to grow without adding administrative complexity at the same rate.
