Corporate fraud investigations are complex, expensive, and high-stakes—which means your prospective clients need proof that you deliver results before they'll trust you with sensitive cases. Case studies are the most credible way to show that proof without compromising client confidentiality.
Why Case Studies Convert Better Than Testimonials
A testimonial says "they were great." A case study shows how you solved a real problem and what the client gained. For investigation services, where trust and track record are everything, case studies command 5–10x higher conversion rates than generic reviews. Potential clients want to see your methodology, your timeline, and the specific outcomes you achieved—especially when they're about to spend $5,000–$25,000 on a corporate investigation or fraud detection engagement.
The bonus: case studies also rank in search results and position you as the expert in your market, whether you're hunting for insurance investigation referrals, corporate due diligence work, or employee theft cases.
Structure a Case Study That Works
A winning case study follows this proven format:
The Challenge Describe the client's problem in concrete terms. Instead of "Client needed fraud detection," write "Mid-sized manufacturing company suspected $150,000+ in inventory shrinkage over 18 months but couldn't identify the source or the responsible parties."
Your Approach Outline the specific investigative methods you used: interviews conducted, databases accessed, timeline reviews, surveillance, forensic analysis, or third-party verification. Be detailed enough to demonstrate expertise without revealing confidential tradecraft or naming witnesses.
The Results Quantify outcomes. Examples:
- Identified three employees involved in inventory diversion within 6 weeks
- Recovered $92,000 through restitution and insurance claims
- Prevented recurring losses by implementing access controls
- Delivered findings in a court-admissible report used in settlement negotiations
Client Impact Explain what changed for them: reduced operational losses, improved internal controls, resolved litigation faster, regained stakeholder confidence, or avoided future liability.
Protect Confidentiality While Still Impressing Prospects
Investigation clients won't sign detailed case study releases—that's the reality. Work around it:
- Use generic company descriptions: "a regional logistics provider" instead of the actual name
- Redact specific addresses, employee names, account numbers, and identifying details
- Focus on the type of case and industry vertical, not the specific client
- Get written permission for each case study before publishing, even if anonymized
- Consider a tiered approach: a one-page summary for your website, a longer version for qualified leads who sign NDAs
Most investigation clients will approve a sanitized case study if it protects their identity and shows they benefited. Frame the request during or immediately after you close the engagement, when the relationship is strongest.
Format for Maximum Impact
A case study doesn't need to be a PDF novelty. Use these formats:
- One-pager: headline, challenge, approach, results (2–3 minutes to read)
- Blog post: 800–1,200 words, indexed by search engines, shareable
- Video testimonial: 3–5 minutes with the client (or you narrating) discussing the case
- Slide deck: for presentations to corporate risk managers or insurance brokers
Post case studies on your website, link to them in email outreach, and mention specific results in sales conversations. If you list your services on Mercoly, case studies become part of your profile and help you stand out to leads searching for investigation providers.

Frequently Asked Questions
Q: Can I use a case study if the client won't let me use their real name? Yes—anonymize identifying details, get written permission that acknowledges the redactions, and focus on describing your process and quantifiable results. Courts and opposing counsel know investigations involve confidentiality; prospects expect it.
Q: How long should a case study take to write? Plan 4–8 hours per case study: 1 hour interviewing the client, 2–3 hours writing and fact-checking, 1–2 hours getting approvals, and 1 hour formatting. If you're juggling active cases, outsource the writing to an investigator who can draft it directly from your case file.
Q: What if I don't have many completed cases yet? Start with your strongest 2–3 cases, even if they're 6–12 months old. Quality matters more than quantity; one detailed, credible case study beats five vague ones.
