Human resources is a tricky and nebulous area for any business, so it's worth turning to human resources outsourcing services if you'd like to manage your HR department more effectively.

There are loads of levels of outsourcing available, from simpler options that cover your payroll or other individual aspects of your HR operation to full Professional Employer Organization (PEO) products that can handle every aspect of your organization's HR.

These services go a step further than the 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.

An HR outsourcing service will cost your company, of course, but you get an awful 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.

We've rounded up the best HR outsourcing services you can find right now. If you need some HR help to boost your business, look no further. And, if you'd like more information about the world of work, here's our choice of the best US job sites of 2021.

1. Oasis

The best all-round HR outsourcing service

Reasons to buy
+Great range of features+A full-service platform+Fortune 500 benefits

Oasis is a PEO service owned by Paychex, and it supplies a full range of HR solutions and services that can cover the entire lifecycle of an employee at your business.

Oasis can develop job descriptions and post adverts to attract new employees – and then select candidates, carry out background screening, and welcome staff to the company. Oasis will also handle your ongoing payroll responsibilities and supply an expert HR service for any issues that arise with staff.

This company handles regulatory compliance and risk mitigation. It can also provide everything you need for long-term employees, from a full employee benefits package to staff management and training options. And, because Paychex owns Oasis, it means you get the same level of benefits you'd expect from a Fortune 500 company.

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.

3. Paychex

A top choice for full-service HR plans

Reasons to buy
+Data-driven insights+Broad range of features+Consultancy available too

Paychex supplies human resources consultancy alongside a full range of PEO services, so you're able to customize your package to suit your business needs. If you need a single service or some guidance on streamlining your in-house HR department, then you'll get it here – and Paychex can step up if you need complete HR outsourcing, too.

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.

You can manage your company's HR needs using Paychex's bespoke online platform, and you can allow employees to change their own personal information – which takes tasks away from your to-do list. You can talk to employees, receive real-time reports, and automate essential activities.

Paychex offers a full PEO service with maximum efficiency, so it's an ideal choice if you want to spend less time on HR and save money while you're doing it.

4. ADP HR Services

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 offers the whole gamut of HR services, from payroll and benefits administration to benefit and compliance management. 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.

5. Infiniti

An excellent option for businesses in the service industry

Reasons to buy
+Huge service and franchise experience+Broad range of services+Ideal for big business

Infiniti HR was created with hotels, service businesses, and franchises in mind, and now it's an excellent PEO provider for all sorts of large organizations. And, unsurprisingly, it's still got loads of ability in the service sectors where it began, and it regularly still works with companies like Best Western, Hyatt, and Baymont.

Infiniti's HR solutions come in four different strands that cover the critical HR responsibilities of any organization, from payroll and recruitment to insurance, risk management, and benefits. These solutions are extremely customizable, and Infiniti's size means that any company can attract staff using an excellent suite of benefits.

The broad range of services and Infiniti's extensive service industry and franchise experience means it's an excellent choice for large companies in that sector. However, it's worth looking elsewhere if you want an HR provider with more mobile technology – or if you need HR coverage for a smaller organization.
