Lizanne Lachat's Review Sourced from Google
I applied to a job listed on Indeed.com through Scion Staffing. I'd never worked with a recruiter before, other than for temp positions. Sarah was an absolute pleasure to work with, so professional and down to earth. She helped guide me through the interview and decision-making process, and followed up each step of the way. She was supportive and non-aggressive. I highly recommend Scion Staffing and would definitely work with them again.

My experience with Scion staffing was phenomenal. My recruiter took the time to get to know me as a person, learn my short term and long term goals prior to referring any possible positions for me. Once that position was referred, she was with me through every step of the interview process. She anticipated questions that may be asked and how best to prepare for them. Really, this was a 5/5 star experience all the way!

As an accounting firm I would give them 1 star. I recently discovered a litany of deductions they failed to consider. You will be given an EA, which is just a glorified tax preparer. They will know nothing and be slow to reply. You might as well get your taxes done by H&R block or a proper independent CPA. If these folks do your taxes, get prepared for a larger tax bill. I strongly advise against it.

HR Outsourcing Company FAQs
What is an HR outsourcing agency?
An HR outsourcing agency is a third-party company that handles some or all of a business’ human resources functions. These agencies manage everything from payroll and benefits to compliance and employee relations.
Businesses typically hire an HR outsourcing agency so they can focus on higher-value initiatives such as talent development and organizational culture, maximize efficiency, and reduce overall expenses associated with maintaining an in-house HR department.
How can an HR outsourcing agency streamline people operations?
An HR outsourcing agency streamlines people operations by centralizing routine, complex functions pertaining to compliance management, payroll, and policy administration, into standardized workflows. These adjustments are intended to reduce error-prone manual interventions and ensure consistency across processes.
Through such specialized expertise and automation, organizations gain operational efficiency and better risk management, which supports workforce planning.
What kinds of organizations benefit most from HR outsourcing?
HR outsourcing tends to deliver the greatest value in organizations where operational complexity or growth outpaces internal capacity. Companies with distributed teams or heavy regulatory requirements also benefit from the precision and standardization an external HR partner provides, while also reducing compliance risk and administrative challenges.
Which HR outsourcing firms are top-rated on DesignRush in 2025?
The top-rated HR outsourcing firms on DesignRush in 2025 are:
What core and specialized HR services do outsourcing agencies provide?
HR outsourcing providers provide the following core and specialized services:
- Payroll processing
- Benefits administration
- Compliance management
- HR analytics and reporting
- Employee onboarding and offboarding
- Recruitment and talent acquisition
- Workers' compensation and risk management
- Employer of Record (EOR) services
- Learning and development programs
- Employee relations and dispute resolution
How do I find the best HR outsourcing firm on DesignRush that fits my budget?
The cost of HR outsourcing services in 2025 is highly variable. While a general range of $45 to $1,500 per month is a common starting point for many businesses, this figure can vary depending on the scope of services provided, the company's size, the complexity of HR needs, and the level of expertise required.
To get a more accurate estimate, here is a price breakdown for various HR services:
- Recruitment: Up to $8,000 for 100 candidates
- Compliance management: $12,000 per year
- Payroll: Up to $250 per employee
- Compensation and benefits: Up to $165 per year
- HR management software: Between $70 and $100 per month
How quickly can companies expect HR efficiency gains?
The timeline for realizing HR efficiency gains can vary significantly depending on the specific functions being outsourced and the complexity of the organization. Immediate improvements are often seen in transactional areas like payroll processing and benefits administration, where a specialized provider can instantly introduce standardized, automated processes.
For other benefits pertaining to talent acquisition or employee engagement, the positive impacts may be more gradual, unfolding over several months to a year as new systems and strategies are fully integrated and adopted.
What should you look for when choosing an HR outsourcing provider?
Here are a few important factors to consider when choosing an HR outsourcing provider:
- High client retention rate, as this indicates strong satisfaction
- Dedicated account management rather than call center support
- Industry-specific experience in your sector
- Staff certifications from SHRM or HRCI
- Team members with ESAC accreditation or IRS Certified PEO status
- 24/7 availability for urgent inquiries
- Transparent pricing with no hidden fees
- Clear error resolution procedures and liability coverage
What red flags should deter you from partnering with an HR outsourcing agency?
When selecting an HR outsourcing partner, certain warning signs can indicate misalignment or risk. Watch out for:
- Opaque pricing, vague contracts, or missing insurance coverage
- Reluctance to share references or explain service models
- Pressure tactics, hidden subcontracting, or “too good to be true” offers
- No clear service-level agreements or dispute resolution terms
What questions should you ask before engaging an HR outsourcing firm?
Here are some questions you should ask before engaging the services of an HR outsourcing firm:
- What specific HR services do you provide, and can I select them individually?
- How do you handle compliance in our industry and locations?
- What happens if you make errors in payroll, benefits, or compliance?
- What is your client retention rate, and can you provide 3-5 similar business references?
- What insurance coverage do you carry to protect our business?
- What is your complete pricing structure, including all fees?
- What are your contract terms and cancellation policies?
- How do you handle billing disputes or service credits?
How does HR outsourcing differ from traditional in-house HR or HR software solutions?
HR outsourcing differs from traditional in-house HR or HR software solutions by delegating a company's HR functions to an external provider, which offers specialized expertise and takes on legal liabilities.
While in-house HR relies on a company's own employees to manage all HR tasks, offering a more hands-on and culturally integrated approach, it often comes with higher fixed costs. HR software, conversely, is merely a tool that automates processes for an internal HR team that lacks the strategic guidance and human expertise that a full outsourcing partnership provides.
What platforms, compliance tools, and HRIS systems do leading HR outsourcing agencies use today?
Leading HR outsourcing agencies leverage a range of sophisticated platforms and systems to provide comprehensive services. For core HR functions, they often use robust Human Resources Information Systems (HRIS) like ADP, Workday, and Oracle HCM Cloud, which integrate payroll, benefits, and employee data management.
For global compliance, particularly with a distributed workforce, they utilize specialized platforms such as Deel, Rippling, and Oyster HR, which are designed to handle complex international regulations and payroll. These agencies also employ compliance-specific tools like ComplianceHR and NAVEX to track and align with federal, state, and local labor laws.
