HR Outsourcing for Small Businesses: The Complete Guide for Phoenix & Arizona Employers

If you run a small business in Phoenix or anywhere in Arizona, HR is probably costing you more than you realise — in time, money, and compliance risk. HR outsourcing for small companies gives you access to a dedicated team of HR, payroll, and benefits professionals, plus enterprise-grade HR software, at a fraction of what it costs to hire even one in-house HR manager.

This guide, written by Focus HR’s Senior Business Consultant Clint Parry (MBA, SHRM-SCP), walks you through what HR outsourcing involves, how it compares to managing HR in-house, and how to decide if a PEO like Focus HR is right for your business.

What is HR outsourcing?

Human Resources Outsourcing (HRO) is the process of engaging a third-party provider — like Focus HR — by contract, for an established fee, to handle HR activities that would normally be performed inside the business.

HRO services are usually provided by a Professional Employer Organisation (PEO). The PEO contracts to share certain responsibilities and liabilities in human resources, workers’ compensation, risk management, employee benefits, and payroll administration. Both parties enter a co-employment arrangement where the business owner maintains 100% direction and control of their employees.

The relationship is governed by a Client Services Agreement (CSA) that clearly details the specific duties, liabilities, and performance standards of the shared employment arrangement.

The goal of HR outsourcing is to increase profitability, productivity, and efficiency for small businesses while mitigating employee-related liability — giving you a dedicated HR team at a fraction of the cost of staffing these resources internally.

Why should I consider HR outsourcing?

Three big reasons employers outsource HR to a PEO like Focus HR.

Free up headspace

Keeping up with federal and state labor law changes — while managing payroll vendors, benefits brokers, workers’ comp, and 401(k) providers — consumes too much owner time. One client reduced HR admin from 30 hours a week to under 8 hours a month.

Mitigate risk

The DOL, EEOC, ICE, and OSHA actively audit small businesses. Being caught off guard is expensive. Focus HR has labor law attorneys on retainer and licensed, credentialed professionals who ensure your business stays compliant.

Lower labor costs

HR admin costs are like a thousand small cuts — individually minor, collectively significant. They multiply as you grow. HR outsourcing aggregates all these costs into a single-source provider that reduces overall spend and drives new efficiencies.

HR outsourcing vs. hiring an in-house HR manager

What does it really cost?

Factor	In-house HR manager	Focus HR (PEO/HRO)
Annual cost (25–50 staff)	$110K–$160K+ (salary, taxes, benefits, software)	Typically $50–$150 per employee/month — request a custom quote
HR expertise	One generalist — knowledge gaps in specialist areas	Full team: HR manager, payroll specialist, benefits executive, workers’ comp manager
Compliance coverage	One person tracking all law changes	Dedicated team monitoring DOL, EEOC, OSHA, ACA, FMLA + Arizona-specific requirements
HRIS platform	Separate licence: $6–$20/employee/month	Included — payroll, time and attendance, onboarding, performance in one place
Employee benefits	Small-group rates; limited plan options	Large-group purchasing power — better plans at lower premiums
Coverage during absence	Single point of failure if HR manager leaves	Full team continuity — no disruption to payroll or HR operations
Scalability	Headcount and cost increase linearly as you grow	Management fee scales with payroll — costs flex with your business
Best for	Companies with 100+ employees needing a dedicated internal culture champion	Small businesses (10–100 employees) wanting expert HR, compliance, and benefits without the overhead

Is HR outsourcing right for your business?

Three key factors to consider.

Employee count

Any business over one employee can outsource HR, but employers with 10 or more employees tend to see the greatest benefit. Above 100 employees, you can assess whether an in-house HR resource makes sense — many larger clients still outsource the transactional side to Focus HR.

Your industry

Focus HR clients span medical, hospitality, manufacturing, construction, retail, transportation, and professional services. HR outsourcing is industry-independent — every business with employees needs good HR, regardless of what they do.

How you handle HR now

Ask yourself: does your current approach feel fragmented? Is your vendor consistently delivering? Does your team have the bandwidth and expertise to stay current with labor law compliance? If the answers are uncertain, outsourcing is worth exploring.

5 steps to effective HR outsourcing

The decision to outsource HR functions to a PEO has the potential to be a game-changer. Here’s the process.

Determine your needs and goals

Know the end in mind. Is this a cost reduction play, a fix for a poor service provider relationship, or a way to improve focus on business growth? Articulating this upfront gives both you and the PEO clarity on what needs to be achieved.

Analyse your current costs

Understand your total cost of labor — wages, payroll taxes, HR admin costs, workers’ comp premiums, health care premiums, and retirement benefits. This gives the PEO the information needed to build a side-by-side comparison against their solution.

Configure the solution

Focus HR offers two models: a PEO model (co-employment under Focus HR’s Federal Tax ID, leveraging shared unemployment and workers’ comp rates) and an ASO model (HR and payroll services only, staying under your own Tax ID). Your current cost and risk situation determines which fits best.

Review the proposal for services

The PEO configures a proposal detailing all services and costs in a transparent way — including any charges outside the management fee. No hidden extras.

Implementation

Once agreed, Focus HR initiates the implementation process. You’ll work with a dedicated Implementation Team to capture your specific requirements and develop a conversion plan. Most clients are fully onboarded within two to four weeks. There will be bumps — a good PEO acts as the shock absorber until you’re running smoothly.

The unexpected value proposition of HR outsourcing

The conventional benefits are obvious. Here are four advantages most business owners don’t anticipate.

Outsourcing as a growth strategy

The right outsourced partners — for IT, bookkeeping, and HR — give you access to best-in-class systems and processes without building them yourself. That’s a strategic edge that compounds as you grow.

Business agility

When a crisis forces cost reduction, HR outsourcing flexes with you. The management fee is a fixed percentage of payroll — when your payroll decreases, so does your cost. In-house HR is a fixed overhead that doesn’t flex.

Access to senior HR talent

Finding and retaining exceptional HR professionals is expensive. Outsourcing gives you direct access to senior HR consultants with years of experience — without the premium hiring cost or the retention risk.

Enterprise-grade technology

A PEO partnership gives you access to the HR systems, tools, and infrastructure that large companies use — without investing a fortune to acquire them independently.

How HR outsourcing saves you time and money

Research from the US Department of Labor, SBA, and US Chamber of Commerce shows that HR administrative costs typically represent 3%–12% of payroll costs for small businesses with 1–50 employees. These costs span:

HR admin

Handbooks, hiring/firing, training, unemployment, compliance, employee relations

Payroll

Processing, taxes, 940/941s, W-2s, PTO, sick leave, reporting

Workers’ comp

Shopping, audit, claims, hearings, OSHA, safety training, classification

Employee benefits

Shopping, ACA compliance, COBRA, HIPAA, elections, remittance

Retirement/401(k)

ERISA compliance, 5500 filing, fiduciary management, annual audit

Working with a PEO reduces your total cost of labor by leveraging the scale of the PEO’s technology and people — and all the administrative time previously spent on these tasks gets redirected to revenue-generating activities. Research commissioned by NAPEO shows the average PEO client saves $450 per employee per year in administrative costs alone.

Frequently asked questions

What does HR outsourcing cost for a small business?

HR outsourcing typically ranges from $50 to $150 per employee per month when working with a PEO like Focus HR. For a 25-person company, that’s roughly $1,250–$3,750 per month — compared to $110,000–$160,000 annually for a single in-house HR manager in the Phoenix area.

Is HR outsourcing a good idea for small companies?

Yes — particularly for businesses with 10 to 100 employees. At this size, HR admin is substantial enough to consume significant owner time, but the business isn’t yet large enough to justify a full HR department. NAPEO research consistently shows PEO clients grow faster, have lower turnover, and are less likely to go out of business.

What HR functions can a small business outsource?

Virtually every HR function — payroll processing and tax filing, benefits administration, compliance and employment law guidance, recruiting support, time and attendance, workers’ compensation, performance management, and employee training. Focus HR handles all of these under one roof with a dedicated team for each client account.

What is the difference between a PEO and an HR outsourcing company?

A PEO like Focus HR enters into a co-employment arrangement, becoming the employer of record for tax and benefits purposes. This allows the PEO to offer large-group benefits rates and share compliance liability with you. A standard HRO or ASO provider handles HR tasks on your behalf but does not share employer-of-record status — you retain all compliance liability.

How long does it take to set up HR outsourcing with Focus HR?

Most clients are fully onboarded within two to four weeks. We also offer a free HR Health Check to identify any compliance gaps before the transition begins.

Does Focus HR serve businesses outside of Phoenix and Tucson?

Yes. While headquartered in Tucson, Focus HR serves clients across 47 states. Our cloud-based HRIS platform means your team can access HR, payroll, and benefits from anywhere. We are particularly well-positioned for Arizona businesses expanding into other states and needing multi-state compliance support.
