Professional Employer Organisation (PEO) ultimate guide

When it comes to expanding your talent pool, there are a lot of different options to choose from. You could try to hire new employees yourself or you could outsource the process to a Professional Employer Organisation (PEO).

PEOs provide businesses with an easy and efficient way to find qualified candidates and expand their operations. In this blog post, we will discuss what PEOs are and why your business should use one.

What is a Professional Employer Organisation (PEO)?

A PEO acts as a co-employer that can manage payroll, benefits and other human resources (HR) responsibilities on behalf of your company. It lets businesses focus on growth by taking on the complexity of payroll, HR, compliance and benefits. This gives employees a better experience and employers less risk, at a cost that typically pays for itself.

Why should businesses use a Professional Employer Organisation?

A professional employer organisation is a cost-effective way for businesses to mitigate the challenges of a number of tasks associated with employment.

For many small and medium-sized businesses, hiring employees from outside their home country is a complex and expensive process and often involves setting up separate entities. Having a PEO takes the guesswork out of hiring international employees by navigating local laws and regulations, compliantly hiring and onboarding employees and offering a range of benefits.

Comprehensive HR outsourcing solutions can be time-consuming and a PEO, which outsources certain functions, saves time, handles workers’ compensation and creates a broader range of benefits for your large or small business and staff.

From recruiting and employee retention to better time management, it is suggested that a PEO will help a company to grow. PEOs also assist with tax administration, compliance and other benefit costs for small and medium-sized businesses.

While there are already many tools in place to assist with things like payroll, a PEO allows you to achieve much more without having to burden your in-house HR resources, or management team if they currently perform these functions.

How does a PEO work?

A PEO can help manage important HR functions like payroll, benefits and compliance. This allows other vital resources to be freed up to focus on strategy, rather than HR admin. It can be difficult to ensure industry compliance with labour and employment laws. A PEO handles this and a range of other tasks, so owners and managers can focus on more essential services with peace of mind.

The process of using a PEO starts with the client company entering into a contract with a PEO of their choosing. This covers the following:

• An agreement that the PEO will act as the administrative employer for specified tasks concerned with the employment relationship, with the client acting as the employer.
• The client company will remain responsible for hiring, managing staff and the non-employee related aspects of the businesses operations.
• The PEO is responsible for processing employee wages, benefits, and withholdings while also reporting taxes in accordance with the employees’ local legislation.
• Some relevant tasks may be shared between the client and the PEO as discussed.

Some PEOs may also include additional features such as Employee Assistance Programs (EAPs) or other benefits to help boost workplace health, morale and employee engagement.

Once in place, a PEO becomes the legal employer for your staff and is responsible for administering all payroll and related benefits.

What are the benefits for a business using a PEO?

A typical PEO will provide a selection of staff with extensive experience in HR, legal, tax purposes, client services and accounting that can reduce admin costs, streamline payroll and help with expansion into international markets. While there are many benefits to outsourcing roles like payroll, let’s dive into the advantages and further benefits of using a PEO.

Having a PEO can bring benefits to your business, such as:

• Reduced HR management costs
• Better HR practices
• Reduced risk

As well as providing employees with opportunities to:

• Go for the most exciting role and not be limited by location
• Have secure employment
• Experience greater diversity at work

Benefits for employers

For an employer, a PEO can provide relief, not only in the time commitment associated with these tasks, but also in a range of recruitment cost savings. If your business is ready to launch into new markets, a PEO saves you the cost and time of setting up a local entity in a new country.

Benefits of a PEO for employees

An accredited PEO ensures all standards are met by automated compliance and policies, with a true understanding of local legalities, you can be at ease knowing you are taken care of. With many collaborative software tools available, they will feel a part of the team regardless of their location with employee wellbeing, training and communication features all accessible to them.

Are PEOs worth it?

The biggest hurdle for most large or small business owners in any industry in adopting a PEO is being comfortable with relinquishing the control over this aspect of their company to a third party. If they do, however, a range of business benefits will be created by the PEO, making the action very worthwhile.

The most significant benefit is the time saved, as a PEO frees up company resources and covers risk management. It also removes time-consuming tasks such as payroll or new employee onboarding. By gaining this support for administrative services, some of the following can be removed from management’s to-do list:

• Recruiting and hiring
• Handbook development for worksite employees
• Creating and managing a benefits package
• Ongoing management training
• Employee coaching
• Creation of a privacy policy and terms of use
• Compensation insurance
• Dismissal processes

What won’t PEOs do?

While PEOs are a great way to ease your administrative burden and handle workers compensation insurance or payroll processing, they cannot, and will not, do everything.

If you are considering a PEO for HR guidance, it is crucial to account for the things that will not be covered and understand what will still remain for the employer responsibilities. The co-employment relationship setup of a PEO allows for a range of responsibilities to be handed over, the running of the business is still very much your responsibility, most notably the management of your team and their operations.

What does the employer remain responsible for?

• Day to day management and supervision of your team, including directing tasks and setting work expectations
• Hiring, promotion and termination decisions
• Worksite safety and operational compliance
• Core business operations such as product development, sales and service delivery
• Performance management and shaping company culture

How much does a PEO cost?

There are a range of factors that will determine the cost of a PEO. This can include the size of your business, the services you choose, and the number of employees you have on the payroll. Most PEOs will charge a flat fee per employee or a percentage of your company’s total payroll regardless of whether you are a large or small business owner.

A good way to account for your company’s expected PEO costs, calculate the yearly expense for both pricing models and keep in mind that when starting a new contract, you may be able to negotiate. Knowing which option is financially better for your business first will help you negotiate with a certified professional employer organisation.

How do you choose the right PEO?

PEOs provide a range of cost, time, and administrative savings, but they may not suit your business model. Consider how comfortable you are with outsourcing these tasks and if it will truly provide a return on your investment. You can do this by considering how much time you currently spend on these HR duties and if there are any gaps in your process that a PEO can improve.

If you decide that a PEO can benefit your company and reduce employee turnover, you’ll need to make sure you choose the right one. Your navigation of the options should consider the human resources outsourcing services and the range of benefits they offer, along with the flexibility they provide in their service agreements.

A PEO will impact your employees and HR functions, so ask the question and take into account the following to find the right one:

Accreditations and auditing

PEOs are highly regulated as they handle sensitive employee data, documentation and cash flow. You will also want to confirm their compliance expertise as this is one of the most crucial tasks they will be taking over from you.

Employee benefits offerings

Consider what benefits and programs the PEO offers and their associated costs. Are they something your employees will find value in or will a different PEO with varied employee benefits be better? Will these help your business?

Service-level agreements

A service-level agreement (SLA) explains the relationship you will have with your PEO. It will discuss not only the services provided but also the responsibilities of your PEO and what you should expect from them. As an employer, a PEO that will help your business will offer clear and straightforward answers to your questions is favourable, as this will give you some idea about the working relationship to come.

What is the difference between a PEO and an employee leasing company?

The main difference between a PEO and an employee leasing company comes down to who the workforce belongs to. A traditional PEO doesn’t supply labour. It works with a client’s existing employees, handling human resources tasks such as hiring support, remuneration, superannuation and employee benefits.

HeroForce goes beyond this standard model. While it still manages your existing team the way a PEO would, it also connects you to a talent marketplace of jobseekers, so you can source new employees through the same platform whenever you need to grow.

On the other hand, an employee leasing service works differently. Instead of supporting a client’s existing team, it supplies a workforce on a temporary or project-specific basis. Leased employees don’t remain with the client company once a project wraps up. Instead, the staffing service reassigns them to a different company for the next batch of work.

This kind of arrangement can see the same staff placed with a client on a recurring basis, but the worker never forms a direct employment relationship with that client, unlike in a PEO setup where the employer-employee relationship sits with the business itself.

Hiring doesn’t have to be this complicated

Whether you’re bringing on a local hire or building a team across borders, the admin that comes with employment shouldn’t be the thing slowing you down. Sorting contracts, running payroll, navigating legal requirements and managing compliance can add up quickly and pull focus away from the actual work of growing a business.

That’s what HeroForce is built for. Employment Hero becomes the legal employer for your staff, handling contracts, payroll, tax and compliance so you don’t have to. You manage the work, while we handle everything else.

With access to a marketplace of jobseekers, AI-assisted candidate screening and the ability to hire across 180+ countries without entity setup, HeroForce covers both models, whether you’re hiring your next local team member or expanding into a new market for the first time.

The wrap up

Relieving yourself of your human resources, payroll, and capital management tasks can take a lot of the pressure off your management. It can also create an environment for happier employees due to the better benefits you’ll be able to offer.

While the time and cost savings for your business are significant benefits, the primary goal is allowing you to focus on growth, making a good PEO an investment in your future.
