Best HR outsourcing service of 2024

The best HR outsourcing services make it simple and easy for you to more efficiently manage your Human Resources admin and costs.

These are especially useful for small businesses and startups, where outsourced HR services can prove far more cost-effective in the short-term than hiring dedicated HR staff for your organization.

There are different levels of outsourcing available, however, from basic options that cover the essentials such as payroll and benefits, to full Professional Employer Organization (PEO) services that can handle every aspect of the HR process, from hiring to onboarding, training and so on.

These services go a step further than traditional HR software that many people use to manage human resources – these companies use experts and professionals alongside their own software and analysis tools to supply a more in-depth service, and they've got in-house legal teams to ensure compliance too. 

Many of the staff at these companies also have decades of experience that may not exist in your business. Additionally, they can use collective purchasing to ensure you get the best deals on compensation and benefits packages.

An HR outsourcing service will cost your company, of course, but you should get a lot in return – and an outsourcing service can save your company money, too. You won't have to pay to train or hire extra staff, and you won't have to rent additional office space.

Some people see HR as a necessary chore, but this is the sort of work that you can easily outsource to a company of experts, and it'll often be cheaper than staffing your in-house department.

Below we list what we think are the best HR outsourcing services currently available.

Best for large business

A significant player for serious businesses

Reasons to buy

Suitable for larger firms
Nationwide service
Different packages offered

ADP HR Services  is an ideal choice if you're responsible for the human resources of a larger business or if you want to free up time to focus on strategy rather than HR. It's also worthwhile if two companies are merging and need an HR provider to help navigate those potentially tricky waters.

ADP can help set up employee self-service processes, and you can rely on the firm's experts if you run into a sticky situation. ADP also supplies employee handbooks and job description wizards to streamline key documentation, and you can compare your company's HR practices against industry standards to see where you fall short.

This company offers different packages – ideal if you need to outsource your entire operation or if you need specific services – and ADP also uses analytics tools to work out where you can improve your business efficiency.

ADP has expertise in dealing with large businesses and complex corporate situations, so it's worth real consideration if you need an unfussy and professional HR provider.

2. Insperity

A top choice for full-service HR plans

Reasons to buy

Nationwide service
Different plan levels
Certified by the IRS

Insperity offers a full-service HR solution that's focused on two specialized plans. The first covers organizations of between five and 149 employees, while the second is well-suited to firms of up to 5000 staff members.

Both cover all key HR areas, from administration and payroll to compliance, benefits, employee management, and training. The plans differ, though, in how those areas are handled.

The small business scheme delivers a well-supported and stable HR plan for companies that are unlikely to have all the required experience in-house – and that stability combines with a range of benefits that a small business wouldn't usually be able to afford.

The large business plan serves up the same broad swathe of services, but concentrates on productivity and profit, with a clear focus on preventing the sprawl and inefficiencies that can afflict larger organizations. Insperity supplies detailed, managed levels of cost and loads of data-based insight.

No matter the plan you choose, Insperity gets the job done using its own scalable HR platform, which allows you to supervise your business and get more work done. You're able to consult with Insperity's experts if you're unsure about any HR-related situation.

Insperity offers a nationwide service that works for smaller businesses and larger enterprises, and the firm claims that companies that use a PEO system grow up to 9% faster – so Insperity is well worth using.

Paychex can handle every big HR task, from payroll and benefits to legal services and training. That's not unusual for a prominent PEO provider. Paychex goes further than rivals by streamlining its services to make your HR operation as efficient and affordable as possible. It does this by using a huge amount of data to deliver unique insights and new opportunities.
