A fraud investigator figures out whether money was taken or misrepresented, proves it with evidence, and writes it up so a manager, lawyer, or prosecutor can act. The work is part detective, part accountant, part writer. You will learn it in three stages: first the basics of how fraud works and how money moves, then the core investigative toolkit (documents, data, interviews, reports) that gets you hired in a bank, insurer, or retailer fraud unit, then advanced analytics and case leadership.

Stage 1 of 3 · about 10 weeks
Understand how fraud happens, how money and records flow, and how to read basic financial documents and spreadsheets.
Fraud basics and the fraud triangle
Before you can catch fraud, you need a mental model for why people commit it. The fraud triangle (pressure, opportunity, rationalization) tells you where to look: weak controls create opportunity, and life pressure explains motive. It also gives you vocabulary for the three big categories in the ACFE Fraud Tree: asset misappropriation, corruption, and financial statement fraud.
Accounting and financial statements
Fraud leaves marks in the books. If you understand debits and credits, the three financial statements, and how a payment moves from invoice to bank, you can spot entries that do not make sense, like a vendor paid twice or revenue booked early.
Excel for investigators
Most early fraud work happens in spreadsheets: sorting transactions, finding duplicates, and totaling by vendor or account. Excel is the first tool every employer expects.
Law and evidence basics
Your findings may end up in court or with regulators. Knowing what counts as evidence, chain of custody, privacy limits, and the difference between civil and criminal cases keeps your work usable and keeps you out of trouble.
