To choose the right outsourcing company for your business, consider these steps:
Need help finding an HR outsource provider for your business? Visit our Marketplace and tell us what you need. We'll curate a list of the top companies for free!
Start with your current employee headcount and projected growth over the next 12-24 months.
Document all locations where you have employees, because each state or country adds compliance complexity that affects pricing.
Gather your existing payroll structure, including pay frequencies, overtime policies, and any special compensation arrangements like commissions or bonuses.
List your current benefits offerings and note whether you want the provider to source new plans or administer existing ones.
Compile your compliance requirements. Are you subject to industry-specific regulations? Do you have government contracts requiring certain HR practices? Have you faced any compliance issues or audits recently? Understanding your risk profile helps providers recommend appropriate service levels.
Finally, establish your budget expectations and decision timeline. Providers appreciate knowing whether you're exploring options or ready to move quickly.
According to a 2025 Paychex study, 64% of companies spend 570 hours annually on HR administration, so quantify your own time investment to understand your potential ROI from outsourcing.
While both HR outsourcing and building an in-house team bring their own advantages, the decision will depend on your specific business needs.
According to Deloitte's Global Outsourcing Survey, these are the top reasons why businesses are outsourcing functions, including HR:
In other words, HR outsourcing makes more sense when:
Outsourcing HR doesn't mean eliminating internal people management, but it means redirecting your focus from administration to strategy.
Your leadership team remains responsible for organizational culture, performance expectations, hiring decisions, and employee development priorities.
The HR outsourcing provider handles execution, compliance, and day-to-day administration.
Expect regular check-ins with your provider. Most start with weekly or biweekly touchpoints during the first few months, transitioning to monthly reviews once processes stabilize.
You'll approve payroll runs, review compliance reports, and make final decisions on employee relations matters.
The provider brings expertise and recommendations; you make the calls, ensuring that everything aligns with your company's values and goals.
To measure if the HR outsourcing company is delivering value to your business, start by defining your expectations and service level agreement (SLAs).
This includes your measurable business objectives, performance metrics, and current benchmarks.
Here are some of the most common HR outsourcing benchmarks to consider:
Small companies with 25 employees and a monthly HRO cost of $120-$200 can expect an average return on investment (ROI) of 150%.
Mid-sized businesses with around 100 employees and a monthly HRO of $430-$500, on the other hand, can experience an ROI of 175%.
For large enterprises with over 500 employees and an HRO of $2,000-$3,000 per month, the average ROI is 191%.

According to industry research, these are the most frequently outsourced HR services:
Beyond these core offerings, these companies also cover performance management, time and attendance tracking, and compliance management.
HR outsourcing costs start at $50-$200 per employee per month and can go beyond $1,500 per employee per month. The final rate will depend on the type of HR sourcing service, engagement model, company size and structure, industry, and compliance requirements.
Here’s a pricing breakdown per service type:
While both HR outsourcing companies and PEOs (professional employer organizations) help organizations hire and manage their employees, they have different functions.
Mainly, an HRO serves as an external vendor, while a PEO operates through a co-employment model. Below are more details:
| HR Outsourcing | PEO | |
| Function | Third-party vendor | Co-employer |
| Legal Liability | Client | Shares responsibility with the client |
| Services | Provides the service as needed | Controls the entire HR operations |
| Payroll, taxes, and filings | Provider handles the service, but the client remains the employer | Provider is the co-employer and administers the entire process |
| Benefits |
