What is small business HR consulting?
Small business HR consulting is senior HR expertise delivered part-time or by project — without hiring an $140K+ HR director. Standard scope covers compliance, handbook, comp bands, hiring process, and performance management. Engagements run $1,500–$8,000 per month. Best fit: companies between 15 and 150 employees that have outgrown a payroll service but can't justify a full HR team. Diagnose your HR gap first.
What Does HR Consulting Cost for a Small Business?
Quotes vary 5x across the market for the same scope of work. Here's what drives the number.
| Engagement Type | Typical Cost | Best For |
|---|---|---|
| Project (audit, handbook, comp study) | $2,000–$10,000 one-time | One-off compliance or policy gap |
| Fractional HR retainer | $1,500–$8,000/month | 15–150 employees, ongoing senior advisory |
| PEO (co-employment) | $50–$200 per employee/month | Outsourced payroll + benefits + compliance |
| Full-time HR director | $11,000–$17,000/month all-in | 150+ employees, multi-state, complex benefits |
When Does a Small Business Actually Need HR Consulting?
- Headcount past 15. Federal compliance load steps up (FMLA at 50, ACA reporting, EEO-1, multi-state withholding).
- Turnover above 20% annually. Each replacement costs 50–200% of salary. One avoided exit pays the consultant.
- Hiring more than 3 people per quarter without a written process. Bad hires here cost 6–9 months of salary to unwind.
- An open compliance question you can't answer. Wage & hour, classification, accommodation requests, terminations.
- An acquisition or restructuring. Integration HR is its own discipline.
If two or more apply, an HR consultant typically pays back inside 90 days. See fractional HR vs. traditional HR for the model comparison.

Owners use these terms interchangeably. They are not the same product.
| Model | Who's the Employer | What You Get | Best For |
|---|---|---|---|
| HR Consultant | You | Advice, audits, project work | 15–50 employees, specific gap |
| Fractional HR | You | Embedded senior HR leader, 5–15 hrs/week | 25–150 employees, ongoing complexity |
| PEO | PEO (co-employer) | Payroll, benefits, compliance bundled | 10–75 employees, want benefits arbitrage |
Most owners pick the wrong one because nobody explained the trade. A PEO gives you cheaper benefits but you lose direct control of your handbook and offboarding. A fractional HR leader gives you control but you handle benefits and payroll separately. Get the trade right before you sign.
What Should Be in the First 90 Days?
- Compliance audit. I-9s, classifications, wage & hour, multi-state registrations, handbook gaps.
- Handbook update or rewrite. Anchored to current state law, not a 2021 template.
- Compensation bands. Three-tier bands by role, benchmarked to market.
- Hiring process. Written scorecard, structured interview, reference protocol.
- Performance framework. Lightweight — quarterly review, written expectations, clear escalation path.
If a consultant won't commit to these five inside 90 days, they're selling hours, not outcomes.
How Sobo Scopes a Small Business HR Engagement
Most HR consultants quote off a script. Sobo runs a diagnostic first — headcount, turnover, hiring velocity, compliance exposure — and matches a consultant priced to fix what's actually broken, not staffed to fill a retainer.
