Trying to figure out what kind of HR support your business actually needs? Most businesses have four basic options: HR software, a PEO, outsourced HR support, or an internal HR hire. Each can be the right choice. The goal is to solve the problems you actually have without paying for more support than you need.

Last updated: October 2026

Quick answer

HR software is usually best for administration and recordkeeping. A PEO can make sense when payroll, benefits, and bundled HR administration are the priority. Outsourced HR support is a stronger fit when the business needs experienced judgment, employee-relations help, or better HR structure. An internal HR hire usually makes sense when there is enough ongoing HR work to justify a dedicated employee.

Sometimes the right answer is a combination

Many small businesses use more than one HR solution. You might use payroll or HR software for administration, then bring in outside support for employee issues, managers, documentation, policies, or difficult decisions.

The cheapest option is not always the most cost-effective if it does not solve the actual problem. The right solution gives you the support you need without adding unnecessary overhead.

What do these options cost?

Costs vary by provider, employee count, location, and complexity. These ranges are a practical starting point for small businesses, not quotes.

HR software

Typical cost: approximately $6 to $15 or more per employee per month, often plus a base fee.

Best for: payroll, PTO, employee records, onboarding, and basic HR administration.

Limitation: software can organize and automate. It cannot make judgment calls, coach a manager, handle a difficult employee issue, or decide what documentation is appropriate.

PEO

Typical cost: approximately $40 to $160 per employee per month in administrative fees, or sometimes 2% to 12% of payroll, depending on the provider and arrangement.

Best for: bundled payroll, benefits, workers' compensation, and compliance administration.

Limitation: a PEO may still leave you needing help with managers, employee issues, performance, documentation, or day-to-day people decisions.

Outsourced HR support

Typical cost: often project-based or monthly, ranging from several hundred dollars to several thousand dollars depending on scope and complexity.

Best for: challenges that involve people, judgment, or difficult decisions, including manager support, employee issues, performance, documentation, policies, terminations, and practical people systems.

Limitation: outsourced HR usually complements payroll and HR software rather than replacing them.

Internal HR hire

Typical cost: roughly $5,000 to $8,000 or more per month in salary alone, before payroll taxes and benefits. For reference, the U.S. Bureau of Labor Statistics reports a median annual wage of $72,910 for human resources specialists as of May 2024. More experienced HR managers earn considerably more.

Best for: businesses with enough ongoing HR work to justify a dedicated internal HR person.

Limitation: this is the highest fixed-cost option, and one HR person may still need outside specialists.

What might this look like for a 20-person business?

HR software: roughly $200 to $500 per month
PEO: roughly $800 to $3,200 per month in administrative fees
Outsourced HR support: a one-time project or ongoing monthly support, depending on the need
Internal HR hire: roughly $5,000 to $8,000 or more per month in salary alone, before payroll taxes and benefits

A note about costs

The ranges above are general market ranges intended to help owners compare options, not a universal price. HR software commonly uses a per-employee pricing model, sometimes with an additional base fee. PEO pricing may be based on a per-employee fee or a percentage of payroll. Internal HR costs vary substantially depending on the experience and seniority of the person hired.

When comparing options, look beyond the monthly price. Consider what the service actually includes, how much hands-on guidance you need, and how much time the solution will save the owner or management team.

What does working with Lean in HR cost?

HR Diagnostic: $1,500. A focused review of your current people practices, risks, and priorities, with practical recommendations for what to address next.

HR Foundation Projects: starting at $2,500. Pricing depends on scope. Projects may include hiring and onboarding, employee documentation, policies, handbook work, performance processes, manager tools, compliance cleanup, and other foundational systems.

Ongoing HR Support: customized level. For businesses that want experienced support without adding a full-time internal hire.

Frequently asked questions

What is the cheapest HR option for a small business?

HR software is often the lowest-cost option if the business mainly needs help with administration, recordkeeping, payroll, timekeeping, or benefits. But the lowest monthly cost is not always the least expensive solution overall. If the owner or managers are still spending significant time working through employee issues, policies, or compliance questions, the business may still need experienced HR guidance in addition to software.

At what point should a small business hire an HR person?

There is no single employee-count rule. A business may need an internal HR employee when there is enough ongoing HR work to justify a dedicated role and employees and managers need frequent daily support. Headcount matters, but so do hiring volume, turnover, number of locations, manager capability, employee issues, and overall complexity. Some businesses need outside HR support well before they need a full-time internal hire. More on that in Do you need a full-time HR person at 20 employees?

Can a small business use HR software and an HR consultant together?

Yes. In fact, that is a common combination. HR software can handle administration, records, payroll, onboarding workflows, and other repeatable processes, while an HR consultant provides judgment, guidance, employee-relations support, manager coaching, policy help, and HR structure. The software manages the system. The consultant helps with the decisions.

What is the difference between a PEO and outsourced HR support?

A PEO typically bundles services such as payroll, benefits administration, workers' compensation support, and HR administration within a co-employment model. Outsourced HR support is usually more focused on experienced HR guidance, employee-relations support, policies, manager coaching, documentation, and HR infrastructure. A PEO may be a strong fit when bundled administration and benefits are the priority. Outsourced HR support may be a stronger fit when the business primarily needs judgment, structure, and hands-on guidance.
