What is a PEO | TopSource

TopSource Worldwide offer a bespoke and comprehensive service for all of our clients that are looking for United States PEO services. We pride ourselves on excellence.

But when you’re busy planning your global expansion, the last thing you want to be worrying about is what all the technical lingo means.

Never ones to let a small technicality hold you back, we thought we’d clarify the most confusing term of them all: Professional Employer Organisation.

What does PEO mean?

A Professional Employer Organisation (PEO) is an outsourcing firm that offers comprehensive HR support and international employment services. These services can include anything from recruitment, payroll processing, benefits scheme management and other admin operations to assisting with local employment law and tax compliance.

Essentially, the PEO becomes the registered employer of your workers through a process called co-employment or joint employment (more on that in a bit). This makes processing payroll, tax, benefits and insurance far easier for the original employer, while still allowing you to maintain all supervisory and management control. In many cases, but not all, PEOs will also assume the legal risk for the employees they hire.

This is where it gets confusing…

You’ll often hear the terms ‘Professional Employer Organisation’ and ‘PEO’ used interchangeably with an EOR (Employer of Record), GEO (Global Employment Organisation) or Global PEO. But while they are all similar, there are some subtle differences — most of which depend on your geographical location.

Generally speaking, ‘PEO’ in its original form is only used in the United States, where providers operate a “co-employment” model. This means there’s a contractual agreement in place, whereby both the client company and the PEO have rights and obligations as an employer. The client organisation will continue to manage the employee’s day-to-day duties and activities, while the PEO providers will take responsibility for the legal employment and personnel-related functions such as payroll.

The key difference to remember between the various types of Professional Employer Organisation models is that, with co-employment, the client company is required to be a legally registered entity in the country where the employees are based.

Do I need a PEO?

PEOs provide a crucial service to businesses hoping to grow overseas. Global expansion is no mean feat. There are hundreds of administrative, regulatory and cost hurdles to jump through first, which can be a daunting task.

Every country (and some regions or states) has its own employment requirements for non-resident companies to contend with. And if you’ve never even heard of things like 13th-month or 14th-month payments, then the challenge of meeting those rules can be a major obstacle to international expansion.

A Professional Employer Organisation takes care of all these challenges. Whether it’s shouldering HR responsibilities, managing benefits like health insurance, assisting with recruitment and visa applications or keeping tabs on local rules and regulations, your PEO will take it all off your plate. Leaving you to focus on your day-to-day business operations and doing what you do best…

Plus, in the international business world, companies that work with a PEO grow faster, have lower employee turnover rates and are far less likely to go out of business!

If you want to escalate your growth plans quickly and employ workers in a different state or country, engaging a PEO will be the best decision you make during your global expansion journey. To find out more about our international PEO services, get in touch today.

PEO stands for Professional Employer Organisation. It is an outsourcing firm that provides comprehensive HR support and international employment services. These can include recruitment, payroll processing, benefits scheme management and other admin operations, along with help on local employment law and tax compliance. The PEO becomes the registered employer of your workers through co-employment, and in many cases also assumes the legal risk for employees it hires.

The terms PEO, EOR (Employer of Record), GEO and Global PEO are often used interchangeably, but there are subtle differences that mainly depend on your geographical location. In its original form, PEO is only used in the United States, where providers run a co-employment model. The key distinction is that with co-employment, the client company must be a legally registered entity in the country where the employees are based.

Co-employment means there is a contractual agreement in which both the client company and the PEO hold rights and obligations as an employer. The client organisation continues to manage the employee’s day-to-day duties and activities, while the PEO takes responsibility for legal employment and personnel-related functions such as payroll. Under this model, the client company must be a legally registered entity in the country where the employees are based.

A PEO is valuable if you want to grow overseas, because global expansion involves hundreds of administrative, regulatory and cost hurdles. Every country, and some regions or states, has its own employment requirements for non-resident companies, including rules like 13th-month or 14th-month payments. A PEO handles HR responsibilities, benefits, recruitment, visa applications and local compliance, freeing you to focus on your core business operations.

According to the post, companies that work with a PEO grow faster, have lower employee turnover rates and are far less likely to go out of business. A PEO takes on HR responsibilities, manages benefits such as health insurance, assists with recruitment and visa applications, and keeps track of local rules and regulations. This lets you escalate growth plans quickly and employ workers in a different state or country.
