Internal Fraud Red Flags and Lawful Investigations

When a Suspicion Needs a Measured Response

You have noticed unusual transactions or employee conduct, but you do not yet know whether it points to fraud. This guide explains the main internal fraud red flags, the records worth checking and the steps needed to investigate lawfully in Michigan. A warning sign is not proof. The aim is to test concerns against independent records without tipping off a subject, damaging evidence or violating employee privacy.

Internal Fraud Red Flags in Conduct and Control

The first clue may be a change in conduct rather than a missing dollar. Unexplained spending, financial pressure or a lifestyle that appears inconsistent with known income can justify closer review. Treat that information as a lead, not a conclusion. There may be an innocent explanation.

Operational gatekeeping is often more useful because it can be checked against company procedures. Watch for an employee who refuses to delegate, avoids cross-training, resists review or will not take leave because someone else would perform the role. Wichita State University identifies control issues such as refusing vacations or promotions for fear that fraud will be detected as possible warning signs.

Risk rises when one person can create a vendor, approve a purchase and reconcile the account. Record the concern and review access rights before confronting anyone. The University of Pennsylvania’s operational internal controls guidance recommends separating authorization, custody, recordkeeping and reconciliation. Temporary dual approval and more frequent account reviews can reduce further exposure while facts are gathered.

Ledger Anomalies and Altered Journal Entries

A single posting error rarely establishes intent. Start by looking for direction and repetition. Honest data-entry mistakes are usually scattered, affect different accounts and are corrected when found. A suspicious pattern repeatedly benefits the same employee, vendor or internal balance.

Relevant signs include missing original receipts, changed invoice amounts, duplicate invoice numbers and checks issued out of sequence. Examine late manual journal entries, especially those posted near a reporting deadline without a clear business explanation. Compare each entry with its approval history and supporting document rather than relying only on a ledger export.

Overrides also need context. An emergency purchase may be legitimate if it has a contemporaneous explanation and visible approval trail. Concealment is different. Altered files, forged authorizations or repeated entries that bypass normal review merit escalation. Preserve the original data before asking the person responsible to explain it.

Procurement Irregularities and Phantom Vendors

Vendor files can expose relationships that invoices hide. Compare vendor addresses, telephone numbers, tax identifiers and payment details with authorized employee and payroll records. A shared residential address or bank account does not prove a fictitious vendor, but it calls for independent verification.

Other concerns include missing taxpayer identification numbers, sequential invoices from a supplier that supposedly handles many customers and vague descriptions for services that cannot be confirmed. Check the full transaction path: purchase order, receiving record, invoice, approval and payment. Missing goods or an absent receiving record can reveal what a valid-looking invoice does not.

Also test transactions immediately below an approval ceiling. For example, repeated invoices just under a company’s secondary-approval threshold may show deliberate splitting. Avoid assuming that every round-number or near-threshold payment is corrupt. Confirm who requested the purchase, who approved it and whether the business received what it paid for.

Physical and Digital Discrepancies

Inventory shrinkage becomes more significant when system balances repeatedly exceed physical counts. Secure perpetual inventory reports, cycle-count sheets, shipping manifests, receiving logs, return records and write-off approvals. Then compare the dates and quantities with badge activity, system logins and available footage from lawful workplace cameras.

Access records may show that credentials were used when the assigned employee was absent or that someone entered a restricted area shortly before stock disappeared. Preserve network authentication records, remote-access sessions and badge logs before normal retention settings erase them. Remember that credentials can be shared or compromised, so a login identifies an account before it identifies a person.

The strongest findings usually come from corroboration. Match transaction timestamps with physical access, device activity and third-party records. If one source conflicts with another, document the conflict rather than selecting only the evidence that supports the initial suspicion.

Lawful Evidence Preservation Under Michigan Law

Once the indicators are credible, involve corporate counsel and limit knowledge of the inquiry to essential personnel. Counsel can define scope, address employment obligations and direct appropriate legal holds. Authorized IT staff can suspend automatic deletion for relevant company email, chat and business files while preserving original metadata.

Michigan law draws important boundaries around digital access. According to the Michigan Legislature, MCL 37.275 preserves specified employer rights to monitor, review or access communications and data on employer-paid devices and traffic using employer networks. That does not permit demanding passwords to an employee’s private social media or non-work email under the Michigan Internet Privacy Protection Act.

Do not place hidden cameras in restrooms, locker rooms, changing areas or other locations where people reasonably expect privacy. Michigan also regulates audio interception, so obtain legal advice before recording conversations. Under Michigan’s Polygraph Protection Act, a private employer must not request, require or administer a polygraph as part of employment or disciplinary action.

Collect only material connected to the allegation. Preserve ledger extracts, bank and payment records, relevant company communications, access logs and existing lawful footage. Record who collected each item, when it was collected, where it came from and whether it was copied or transferred. Do not alter an original file merely to make it easier to review.

Building a Defensible Case for Counsel and Police

A defensible investigation requires more than a folder of suspicious documents. It needs a written allegation, a controlled scope and a timeline of every investigative action. Interviews should follow evidence collection where practical, allowing questions to be based on records rather than assumptions. Counsel should guide employee notices and any required warnings.
