Workplace investigations are a high-margin service, but pricing them wrong leaves money on the table or prices you out of the market. Getting the structure right—hourly, project-based, or retainer—directly impacts your ability to win clients and scale your employment law practice.
Understanding the Investigation Scope
Before you can price anything, you need to know what "investigation" means to your prospects. Are they asking for a harassment complaint review, termination documentation audit, discrimination allegation analysis, or a full forensic investigation with interviews and evidence gathering? These range wildly in complexity and time investment.
A simple document review of an HR complaint might take 5–8 hours. A multi-witness investigation with depositions, timeline reconstruction, and a formal report can run 40–80+ hours. Your intake process must clarify scope immediately, or you'll underestimate every single job.
Hourly vs. Project-Based Pricing
Hourly rates for employment investigators typically fall between $150–$350 per hour, depending on your market, experience level, and reputation. Senior partners with litigation background command the higher end. This model works well when scope is uncertain, but clients hate invoice surprises.
Project-based pricing eliminates scope creep and gives clients certainty. A straightforward HR complaint investigation might be quoted at $2,500–$5,000. A complex, multi-party investigation with documentation review, interviews, and a formal report could run $7,500–$15,000+. The key is building historical data: track how many hours similar investigations actually took, then apply a markup for profit and contingency.
Most successful employment law firms use hybrid pricing—a base project fee with hourly rates for anything that exceeds the defined scope by 20% or more.
What to Charge For
Don't leave money on the table by bundling too much into one fee. Break out billable components:
- Initial complaint review and scope assessment ($500–$1,500)
- Witness interviews (hourly or per-interview, e.g., $300–$500 per interview)
- Document gathering and analysis (hourly)
- Report drafting (often 15–25% of total investigation time)
- Legal analysis and recommendations (separate from investigation hours)
- Follow-up and supplemental investigation (if new facts emerge)
Some firms charge a "rush fee" (20–30% premium) for investigations needed within 5 business days. Others use a retainer model for corporate clients running multiple investigations annually—typically $2,000–$5,000 per month for priority access and reduced per-project rates.
Packaging for Corporate Clients
Large companies want predictability and standardized packages. Consider offering tiered options:
- Standard Investigation: Initial complaint review, 3–5 witness interviews, document analysis, written findings ($3,500–$5,500)
- Comprehensive Investigation: Full scope with 8+ interviews, timeline reconstruction, detailed report with legal recommendations ($8,000–$12,000)
- Emergency Investigation: Same as comprehensive but completed within 48–72 hours, premium pricing (+40–50%)
This packaging makes it easier for HR managers to budget and simplifies your sales conversation. They pick the tier that fits their need.
Building Value Into Your Pricing
Clients don't hire you for hours—they hire you to reduce legal exposure, document defense, and protect the company. Your pricing should reflect that value, not just time. A thorough investigation that shields the company from a discrimination lawsuit is worth significantly more than the 60 hours you logged.
Consider including:
- Executive summary for leadership
- Litigation readiness assessment
- Policy gap analysis and recommendations
- Witness credibility assessment
These add perceived value without proportional time investment, justifying higher project fees.
Getting Found and Winning Clients
Employment law is competitive, and most business owners searching for investigation services start online. Listing your services on platforms like Mercoly helps you get found by corporate HR teams and business owners actively seeking investigators, and it lets you showcase your packages clearly to win leads and close deals faster.
Marketing Your Rates
Transparency builds trust. Your website should mention investigation pricing ranges (e.g., "Complex investigations: $7,500–$15,000"). Call out what's included, turnaround times, and your investigator credentials. Prospects want to know they're paying a skilled attorney or licensed investigator, not a junior paralegal.
Frequently Asked Questions
Q: Should I charge differently for internal vs. external investigations? External investigations typically cost more because they often involve more interviews, travel, and third-party coordination. Most firms charge 15–25% more for external scope.
Q: How do I handle scope creep when new facts emerge mid-investigation? Set clear boundaries in your engagement letter: define what's covered in your base fee, specify that investigation beyond the original scope will be billed hourly, and notify the client in writing before pursuing new leads.
Q: Can I offer a retainer for multiple investigations? Absolutely—most corporate clients prefer it. A $3,000–$5,000 monthly retainer usually covers 1–2 standard investigations, with overage billed hourly, creating predictable revenue and client loyalty.
