When it Makes Sense to Invest Into HR Outsourcing Services

HR outsourcing services are extremely popular for small businesses. 

Most small businesses can’t afford to have a dedicated HR staff on the payroll.

So it’s common for HR responsibilities to fall on the bookkeeper or business owner.

But neither of these people are really qualified to do this job. Plus, bookkeepers and owners have other responsibilities to handle. So they really can’t dedicate enough time to HR, causing the department to suffer.

So if your business has outgrown your make-do HR team and you’re ready for a dedicated HR staff, outsourcing this department is a cost-effective alternative to hiring in-house employees.

HR outsourcing services will ensure a smooth onboarding process and make sure that your company remains compliant with all local, state, and federal employment laws. 

Businesses that are scaling and hiring new employees should definitely consider HR outsourcing.

HR outsourcing is also growing in popularity for larger organizations and mid size businesses. It’s much more cost-effective when you’re able to outsource HR staff compared to hiring more people in-house.

Methodology For Choosing The Best HR Outsourcing Services

With so many different HR outsourcing services available on the market today, finding the best one for your business can be challenging. To make things easier for you, we’ve identified the top features and considerations that must be evaluated as you’re shopping around. 

Company Size

While some HR outsourcing firms work with businesses of all shapes and sizes, that’s not the case for all of them. Certain options are better suited for small businesses, while others are definitely geared towards mid size organizations.

It should be pretty easy for you to start narrowing your search right away using this criteria. Make sure the service provider you’re evaluating actually works with your business size and industry.

Full Service vs. Individual Solutions

What exactly are you looking for in an HR outsourcing service?

Some businesses want their entire HR department outsourced. But that might not be the case for everyone. There are certain providers that offer a la carte or individual services. These can be retained on a short or long-term basis, according to your needs. 

Payroll and Benefits Administration

Payroll and benefits administration are two crucial components of human resources. But again, not all of you necessarily need to switch from your existing payroll and benefits solution. 

But for businesses in need of a full-service HR solution, this should be at the top of your list.


Keeping up with local, state, and federal laws can be difficult. So I strongly recommend using an HR outsourcing service that can make sure your business is following the appropriate laws.

Some firms definitely have an edge in this category over others. For larger businesses with complex needs and strict industries, HR compliance is definitely something that needs to be a priority. 



Best For Benefits Administration

ADP helps businesses of all sizes with retirement plans, group health insurance, and workers’ compensation packages. ADP is also known for its payroll services.
