FAQ: HR Outsourcing

When should you outsource HR?

Outsourcing HR is beneficial for businesses in various situations, including limited HR expertise, cost considerations, scalability needs, compliance complexities, cost-effectively adding to your HR department, and the desire to focus on core competencies.

Are HROs and PEOs the same?

No, HROs and PEOs differ based on the organization you choose for outsourcing. 

Most HROs provide comprehensive HR services as an external department where they work as the consultant and you as the employer. You can pick and choose which HR services you would like to have outsourced if you do not want their comprehensive solution.

While PEOs also offer comprehensive HR services, they operate under a co-employment model to provide you access to bulk employee benefits, insurance, and shared liability. With co-employment, the PEO becomes the employer of record for tax purposes, meaning all employee paychecks are processed under the PEO’s employer identification number. Although this relieves you from liability for payroll processing mistakes and penalties, you are still responsible for managing the day-to-day operations as the worksite employer.

Which HR functions can be outsourced?

HR functions that can be outsourced include payroll, benefits administration, onboarding/offboarding, policy implementation, compliance management, training and development, performance management, record-keeping, HR technology and systems, HR consulting, and more.

How much does HR outsourcing cost?

Aside from management fees, the cost of HR outsourcing is dependent on what your company is currently spending or not spending. A good way to know if it financially makes sense would be to look at your HR function today – do you need to outsource? The cost of HR outsourcing can vary based on business size, services required, complexity, and chosen provider. Pricing is typically per employee with additional costs for extra services. It's crucial to consider value and expertise when evaluating providers. 

How do benefits and perks impact employee satisfaction and retention?

Benefits and perks enhance satisfaction, work-life balance, well-being, and retention. They improve morale, engagement, and productivity within the organization.
