A Professional Employer Organization (PEO) is essentially an outsourced Human Resources (HR) department. The PEO becomes the “Employer of Record” when it takes over HR-related tasks such as payroll, benefits, workers’ compensation and unemployment claims, so executives must choose a trustworthy and reputable PEO.

Outsourcing HR can benefit startups, growing businesses, international companies and employers with a high turnover. PEOs offer different levels of support to cater to many types of businesses. To get the most out of their service, executives should evaluate which services their company actually needs.

Services offered

PEOs offer several different types of services. Figuring out which services you need can help you narrow down the PEO that will work best for you.

  • Payroll: PEO services that handle payroll will take care of tax withholdings, deposits and compensation, payroll compliance, payroll management reports, garnishment/deduction administration, PTO accruals and online paystubs. Having a PEO take care of this service is ideal if you don’t have a staff member who is dedicated to taking care of payroll.
  • Benefits: PEO-sponsored benefit plans generally offer employees more options than a company would be able to obtain on its own. These benefits can include medical, dental, vision, a flexible spending account, retirement, life insurance and more. Your PEO can also make sure your company is in compliance with the Patient Protection and Affordable Care Act.
  • HR administration: Your PEO can work with your existing HR team or can function as an outsourced HR team, depending on your company’s needs. A PEO will help you manage onboarding and termination, liability management training, employer verification and more. They can even create and distribute your employee handbooks.
  • Recruiting: Some PEOs specialize in recruitment, and they will work with you to design a customized recruitment plan for your business or organization.

    Training

    Most PEO companies offer some form of training for your management team and/or HR employees. Training can vary from company to company, so it’s important to consider what type of training you want out of your PEO company before choosing one.

    • Online: Online training can be the most flexible, since you can choose when and where employees take online training courses. Some online training courses are available for free, while others come at a cost. Make sure to determine your PEO’s training cost structure before signing on.
    • Regional: Some PEOs hold regional training events throughout the year for all of their customers who operate within a specific region. This may require some travel time for you and your team, so find out what is offered during regional training sessions and where they are located.
    • On location: Some PEO companies will travel to your location for more personalized training. This type of training can be beneficial if you have an in-house HR team and/or for larger companies.

    Employee perks and conveniences

    Many PEOs offer certain perks for a company’s employees, which can make your company more appealing to talented candidates. How many perks you want to offer employees will determine which PEO you use.

    • Discounts: Many PEOs partner with major retailers and brands to offer discounted rates on attractions, hotels, restaurants and more that employees can utilize year-round.
    • Mobile apps: Mobile apps make it easy for employees to keep track of their benefits and retirement planning. They can also make it easy to change tax information, view deposits and learn more about all the benefits their PEO offers.
    • Transitions: Some PEOs offer assistance for employees post-termination, including polishing a resume and finding another place of employment. This type of service benefits both employers and employees.

    Customer support

    Whether you have a quick question or a complicated challenge, you need a PEO with an accessible support system.

    • Call center: Some smaller companies operate with a call center during off hours. This means you will talk to a person anytime you call, but you won’t actually get an answer to your question until a company representative is available, which is generally during normal business hours.
    • Direct representative: Some companies only answer the phones themselves, which means you will only talk to a company representative when you call for support. Their hours may vary, so make sure you know what times someone is available.
    • In-person: Some PEOs will respond to training questions and other complicated challenges with an in-person visit. Likewise, PEOs that operate within a specific region or state might be more likely to offer in-person visits than national PEOs.
    • Personal consultant: Some PEOs will designate an assigned personal consultant for your company, so you work with the same person every time you have a PEO question or need. It’s important to work with someone you trust and can communicate with.

    Accreditation

    PEOs handle large amounts of cash, and working with one that is accredited means you are working with one that is guaranteed to be reliable and regulated. Note that many PEOs that are not currently accredited are still reputable and upstanding companies, so you should not base your PEO decision solely on accreditation.

    • ESAC: The Employer Services Assurance Corporation (ESAC) is an independent non-profit corporation that provide accreditation and financial assurance programs for the PEO industry. To be accredited by the ESAC, a PEO has to provide ESAC comprehensive compliance data, which is verified by a team of financial and legal advisors along with ESAC’s surety carrier. Interested businesses can verify the accreditation status of any PEO on ESAC’s website.

    Business size

    The size of your business will impact what you need from your PEO along with how much money you can afford to spend on one.

    • Startups and small businesses: Hiring a full-time HR representative can be more costly than hiring a PEO for startups and small businesses (1-100 people). These businesses will likely need a PEO to handle most HR functions and to ensure they are compliant. Note that businesses with less than 10 employees may have difficulty finding a PEO that will accept them on a group insurance policy, so make sure to ask about group insurance policy acceptance if you have less than 10 employees.
    • Midsize businesses: Midsize businesses (100-250 employees) may not find a PEO to be cost-effective, but the benefits of hiring a PEO to handle compliance, health insurance, worker’s compensation and other HR-related issues can quickly outweigh the financial cost.
    • Large businesses: Businesses with 250-1,000+ employees will have specific needs from their PEO. These may include training, recruiting, background screening and other tasks that go beyond basic HR functions. Look for a PEO that specializes in working with large businesses.

    What are different types of PEO services?

    Full-service HR

    A PEO that handles full-service HR functions will take care of all of your administrative needs, including payroll, taxes, worker’s compensation, insurance and benefits. These services might be offered a la carte or as a bundled full-service HR package. This type of PEO is useful for businesses who don’t have a dedicated HR department.

    Recruitment

    A PEO dedicated to recruitment will help you navigate the recruitment from start to finish, including writing a job description that will attract top talent, determine the appropriate wage amounts for each job, manage the interview process and even take care of reference and background checks.

    Who's it for?

    Companies with international employees

    Companies that frequently hire international employees will want to work with a PEO that specializes in handling immigration paperwork and maintaining compliance. This will make the recruiting, hiring and training process much easier and ensure you are following all regulations and laws.

    Startups

    Startup businesses often don’t have a budget for HR, and the business owner ends up taking on the added role of HR representative. This can have serious consequences if you are not compliant and/or make a payroll mistake. Hiring a PEO is often less expensive than hiring a full-time HR representative, and it is worth the upfront cost to avoid making costly mistakes down the road.

    Growing businesses

    Growing businesses may need a PEO to help them transition from one size to the next. A PEO can help find the best benefits for your employees as you move from a small to midsize or larger business.

    Companies who do a lot of hiring

    Companies who hire frequently will want a PEO that offers recruiting as one of their services to attract, hire and retain talented individuals.

    Job seekers

    Some PEOs offer their recruiting services to job seekers, who can use the PEO to find jobs related to their skillset. This can give you an advantage when job seeking.
