Think of it like this. The first choice is full-service, and the second is á la carte.

For those of you who already have an in-house HR department with the infrastructure in place, the ASO model will likely be a better option for you. If not, I’d recommend the PEO services.

Compare Quotes From The Best HR Outsourcing Services

Get matched up with a HR outsourcing service that fits your needs.

Current HR Maturity

Outsourcing firms typically have experience working with certain types of businesses. It all really boils down to if you have an HR system already and—if you do—how long you have had it.

For example, if you’re a small business owner with no HR infrastructure, you want to choose a service that has experience building from the ground up with smaller organizations.

Large companies might not need that type of assistance. Instead, a larger business might just need a certain role or task outsourced.

No matter what, decide whether or not you’re looking to simply add onto your current HR infrastructure, or if you’re looking to fully outsource it. For example, you might be a growing company that needs to fill a few gaps like onboarding, or you might be a very large company looking to outsource routine elements like payroll.

ASO vs PEO Providers

Nearly every HR outsourcing firm has similar services. They might vary slightly from company to company.

Some of the companies on our list are PEO providers. These services provide businesses with big HR services like payroll, benefits such as insurance and 401k, and worker’s comp.

PEO providers are also considered a “co-employer” of workers. That means if there’s a legal issue with your employees, both you and your PEO provider assumes responsibility. You agree beforehand how liabilities you each assume.

There are also ASO services that also provide assistance in payroll and benefits. However, they’re not co-employers of your workforce.

They’re both typically the same in cost. All that it really comes down to is how much responsibility you’d like to assume over your employee’s benefits. Since PEO’s are co-employers they’ll be more hands-on with any issues that may arise with your employees.

Streamlining Routine Tasks

Look for an HR outsourcing service that has the tools and technology to streamline your HR processes. Mobile apps and employee self-service tools should be standard.

That way, tasks such as clocking in, clocking out, measuring task times, and possible field work can be managed automatically. Also, benefits electing and taking time off can be automated.

Alternatively, you could consider using platforms like Zenefits. If you don’t have the funds to hire an outsourced HR service, this platform provides software to improve your HR tasks.

Specialty

Does your business need something specific?

For example, maybe you own a company in an industry with strict labor compliance laws. In a situation like this, you’d benefit from an outsourced HR service like Engage PEO. They have attorneys that specialize in employment law.

Or maybe you need an HR service that can improve your payroll process. Paychex would be the best option if you fall into this category.

Whatever unique circumstances your business might have, there is usually a human resource outsourcing service that specializes in it.
