When fraud hits, it rarely announces itself. It shows up as unexplained spend, mysterious “round” invoices, a stock variance that never quite ties out, or a vendor who can’t be found at their listed address. At that point, you don’t just need suspicion—you need facts. Private detectives (working hand‑in‑hand with legal, finance, and internal audit) give companies a fast, discreet way to confirm
Why Fraud Risk is Higher Now
- Hybrid work and weak segregation of duties: Remote approvals, rushed processes, and “temporary” workarounds that never went away.
- Complex supply chains: More vendors, more drop‑ships, more places to hide margin or duplicate services.
- Digital payments and BEC scams: Faster rails mean money moves before anyone blinks.
- Insider‑outsider collusion: Kickbacks, ghost vendors, padded invoices, “friendly” inspections.
- Talent churn: Handovers missed, access left open, policy drift.
What Private Detectives Actually Do (And Why It Works)
Think of detectives as your field‑tested fact‑finders who complement auditors and lawyers.
- Evidence‑first approach
- Preserve what matters: emails, devices (with forensics partners as needed), CCTV pulls, delivery logs, and vendor files.
- Chain‑of‑custody so your counsel can use it.
- On‑the‑ground validation
- Site visits to “vendors,” warehouse walk‑throughs, route checks, and discreet interviews.
- Lifestyle audits (lawful) when kickbacks or unexplained wealth are suspected.
- OSINT and records
- Corporate registries, litigation databases, sanctions/adverse media, beneficial ownership trails.
- Targeted surveillance (where lawful)
- Short, focused observation to verify patterns—not TV‑style stings.
- Coordination
- Work with legal, compliance, internal audit, and insurers to ensure any recovery or claims stand up.
Common Corporate Fraud Types and the Red Flags
| Fraud type | Red flags you’ll notice | How detectives add value | Likely outcome |
| Procurement kickbacks | Same vendor always wins, vague SoWs, split POs just under approval limits, lifestyle jumps | Vendor site checks, pricing benchmarks, links between vendor and staff, timeline of favors | Conflicts proven, vendors rotated/removed, policy fixes |
| Ghost vendors/duplicate vendors | Similar names/addresses, round‑figure invoices, PO without GRN, bounced phone numbers | Registry checks, doorstep validation, bank/KYC anomalies, IP/device overlaps (with forensics) | Fake vendors closed, recovery pursued |
| Inventory shrinkage | Chronic variance, “damaged” stock with poor documentation, odd after‑hours movements | Covert observation, route shadowing, CCTV review, weighbridge/log reconciliation | Theft ring disrupted, controls tightened |
| Expense/petty cash abuse | Repeats near limits, weekend/holiday claims, hand‑written bills, “lost receipt” pattern | Merchant checks, geo/time verification, pattern analysis with interviews | Repayment + HR action, policy changes |
| Payroll/ghost employees | High OT in one unit, no HR records, same bank/phone reused | Address checks, in‑person verification, bank/ID cross‑checks (with consent/legal basis) | Cleanup of payroll, duty roster redesign |
| IP leakage/counterfeit | Complaints spike, look‑alike products in market, sales dip in certain regions | Market sweeps, mystery shopping, supply‑chain tracing, TSCM if leaks suspected | Takedowns, criminal referrals, distributor changes |
| Business email compromise (BEC) | Sudden bank detail changes via email, urgency to pay, domain look‑alikes | Header analysis, domain forensics (with specialists), process audit | Funds hold/recovery attempts, SOP hardening |

How a Professional Fraud Investigation Work (Step‑by‑Step)
Intake, legal framing, and hold

- Litigation hold and access controls: freeze relevant email/file shares, badge logs, CCTV retention.
Plan and OPSEC

- Discreet approach to avoid tipping suspects; need‑to‑know communications.
Evidence preservation and data review
- Pull vendor masters, PO/GRN/Invoice trails, payment files, card statements.
- With digital forensics partners (as needed): defensible device imaging, email header analysis, log pulls.
Fieldwork and validation
- Vendor site visits, warehouse checks, route shadows, spot counts, and third‑party verifications.
- Short‑burst surveillance (where lawful) to confirm behavior, not entrap.
Interviews (PEACE model)
- Planning, Engage/Explain, Account, Closure, Evaluation—structured, non‑coercive, and documented.
Synthesis and reporting
- Timeline with facts: who, what, when, amounts, and method.
- Annexures: photos, site notes, registry extracts, logs.
- Recovery options: civil/criminal pathways, insurer notifications, HR actions, and control fixes.
Handoff and remediation
- Briefing to counsel, compliance, and the board.
- Support for law enforcement engagement where appropriate.
- Implementation support: vendor cleanup, process redesign, training.
Legal and Ethical Boundaries
A good investigation protects your case by staying squarely within the law.
- No hacking, illegal interception, or “CDR” procurement.
- Respect privacy and employment laws; follow your jurisdiction’s data protection rules (e.g., DPDP Act 2023 in India).
- Anti‑bribery: investigations will not involve bribes or inducements (FCPA/UKBA awareness).
- Documentation that meets evidence standards; counsel involvement from day one.

Case Snapshots (Anonymized)
The “vendor in a suitcase”
A mid‑sized manufacturer paid a maintenance vendor ~₹1.8 crore over 18 months. Site checks found a co‑working address, no inventory, and “technicians” who were actually subcontracted at 40% of invoice value. Registry and social links connected the vendor’s director to a plant supervisor’s cousin. Result: vendor terminated, supervisor exited, ~₹52 lakh recovered, controls updated (competitive bids, vendor KYC, three‑way match).
Shrink that wouldn’t quit
Retail DC variance hovered at 2.4% despite audits. Detectives mapped overnight forklift movement and compared to CCTV blind spots. A short, lawful observation run identified a team colluding at the dock. Outcome: ring removed, cameras and weighbridge SOPs fixed, variance dropped below 0.7% in 90 days.
“Urgent” payment change
AP received an email “from” a global supplier to switch bank accounts. Header analysis showed a look‑alike domain; detectives and IT froze payment, contacted the real supplier, and alerted the bank. Funds never left. AP process updated: dual verification and call‑back on verified numbers for any bank changes.
Prevention After Detection: Controls That Work
- Vendor governance
- Clean the vendor master; verify addresses and ownership; avoid look‑alike names.

- Clear SoWs and measurable deliverables.

- Board‑level visibility
- Quarterly fraud risk review; incidents and learnings; KPI dashboard (losses prevented, recoveries, hotline volume).
Costs, Timelines, and Deliverables
- Timelines
- Focused procurement or expense probes: 1–3 weeks
- Multi‑site inventory/shrink investigations: 3–6 weeks
- Complex collusion/financial statement concerns: phased over 6–10 weeks

Myths vs Reality
- Myth: “An internal audit is enough by itself.”
Reality: Audits are vital, but field validation and discreet observation often surface what the spreadsheets can’t. - Myth: “We’ll confront the suspect and get the truth.”
Reality: That risks spoliation and retaliation. Preserve evidence first, then proceed with counsel. - Myth: “Surveillance will catch everything on camera.”
Reality: Most cases are solved by patterns—documents, site checks, and interviews—supported by targeted observation. - Myth: “If we find fraud, we must go public.”
Reality: Options include internal resolution, civil recovery, insurer claims, and criminal referral. Your counsel will guide strategy.
FAQs
Q. What should we do the moment we suspect fraud?
Preserve first, investigate second. Freeze relevant data (emails, logs, CCTV), restrict access quietly, alert counsel, and engage an investigator under privilege. Avoid confrontations or mass emails.
Q. Is hiring a private detective legal for corporate cases?
Yes—when methods are lawful and documented. A reputable firm coordinates with your legal team and follows evidence standards.
Q. Will employees find out there’s an investigation?
Work proceeds on a need‑to‑know basis with discreet site work. Some stakeholders will know; the broader staff typically won’t—unless HR or legal steps require disclosure.
Q. Can you recover losses?
Sometimes—via civil recovery, supplier offsets, insurance claims, or criminal restitution. The first step is proving what happened and quantifying it.
Q. Do detectives do digital forensics?
They coordinate with accredited forensic partners for device imaging, email/header analysis, and logs—so evidence stands up to scrutiny.
Q. When do we involve police?
Your counsel will advise. In many cases, companies complete an internal investigation first, then refer with a well‑documented brief to speed action.
