Accounting Fraud Detection Simulation

Fraud detection simulation where students test earnings quality

The Finsimco Accounting Fraud Detection Simulation hands each student eight years of a listed company's accounts. Profit rises every year, cash from operations stops moving in year four, and the explanation has to be evidenced.

At a glance

Duration

About 3.5 hours

You set every stage timing from the professor panel, so it fits one block or splits across two sessions.

Format

Single-player simulation

Each student holds the screening, testing and conclusion roles in turn and submits one written conclusion.

Level

Undergraduate to MBA

Adjustable: one revenue recognition issue with clear evidence, up to a judgemental estimate and a restatement.

Professor tools

Timeline and session controls

Manage students, adjust stage timings, control progression and monitor individual inputs.

Prerequisites

Financial statements

Students need an income statement and a cash flow. Accruals, manipulation indices and digit tests are taught inside.

Delivery

In class, online or hybrid

The web-based simulation supports in-person, remote, blended and homework-supported delivery.

Assessment

Optional, per student

Every submission is individual, so the screening work, the tests run and the review answers export per student.

Course fit

Fits accounting and audit modules

Designed for Financial Accounting, Auditing, Forensic Accounting and Corporate Governance courses.

Concepts covered

The topics an accounting fraud detection module has to cover: earnings quality and the accrual, operating cash flow against reported profit, manipulation indices and digit tests, revenue recognition and capitalised costs, aggressive judgement against misstatement and writing a conclusion the evidence supports.

The gap between reported earnings and the cash that supports them. The chart runs over eight years. Reported net income climbs smoothly from forty million dollars to a hundred and twelve, the line a board likes to show. Cash from operations tracks it for the first three years and then flattens, ending at fifty-one million. The shaded wedge between the two is the accrual, and it widens every year from year four onwards, which is the single most reliable warning sign in published accounts. The lower panel scores five of the inputs to a standard manipulation index: days sales in receivables, gross margin, asset quality, sales growth and the depreciation rate, with three of five already outside their normal range.

The first chart any forensic analyst draws. Reported net income climbs smoothly from forty million dollars to a hundred and twelve. Cash from operations tracks it for three years, flattens, and ends at fifty-one. The shaded wedge between them is the accrual, and it widens every year from year four. An accrual has to reverse eventually, so the wedge is a loan taken against a future year's earnings. The lower panel scores five inputs to a standard manipulation index, three of them already outside the range a clean company sits in.

Learning outcomes

Written to drop into your module descriptor without rewriting. On completing the simulation, your students will be able to:

  • Identify where reported earnings stop being supported by operating cash flow.
  • Explain why a widening accrual has to reverse and what that implies.
  • Compute and interpret a set of manipulation indicators against a published set of accounts.
  • Distinguish aggressive but defensible judgement from misstatement.
  • Explain why a fast-growing business legitimately absorbs cash and how that story is used.
  • Write a conclusion that states only what the evidence supports.

What students do

Each student works the file alone, holding the screening, testing and conclusion roles in turn. All three want something different from the same accounts, and only one conclusion is submitted.

Accounting Fraud Detection Simulation gameflow, five stages. Stage 1 Briefing, Role setup, 15 min: Watch intro video, Review the accounts, One student holds all three roles, Review role, goals, and success criteria. Materials: briefing docs, eight years of accounts, role cards. Stage 2 Screen & Test, Finding the gap, 60 min: the screening role plot earnings against cash, find the break year, flag the accounts; the testing role run the indicators, sample the transactions, test the digits; the conclusion role record what is supported, separate signal from finding, hold the threshold. Materials: ratio pack, indicator model, transaction sample, tool tips. Stage 3 The Explanations, Management answers, 55 min: the screening role test the explanation, check the segments, re-run the scan; the testing role trace the contracts, confirm the receivables, date the entries; the conclusion role weigh the answer, escalate or close, draft the report. Materials: management responses, contract files, audit papers, live scores. Stage 4 The Conclusion, Write the call, 40 min: show the evidence, state the conclusion, answer on the threshold, submit the review. Materials: review questions, evidence log, outcome report, review pack. Stage 5 Debriefing, Results and feedback, No limit: review your evidence, compare the conclusions, review the outcome, reflect on feedback. Materials: winners, completion summary. Total duration about 3.5 hours.

The gameflow every student sees before they start. The three roles come into play during the testing and the explanations; briefing, the conclusion and the debrief are worked as a single view. Materials arrive stage by stage: eight years of accounts and role cards at briefing, then the ratio pack, indicator model and transaction sample for the testing, then management's responses, the contract files and the audit papers.

Screening

Students read eight years of accounts to find where the relationships between the statements stop holding, which is where everything else has to start.

Testing

Students run the indicators and the transaction-level tests, knowing each one produces a signal rather than a finding.

Conclusion

Students write what the evidence actually supports, because an accusation that cannot be evidenced is worse for everybody than one that is never made.

How it works

Five stages. Students screen eight years of accounts, test what they find and write a conclusion they can defend.

  1. 1

    Stage 1 · 15 min

    Briefing Docs · Eight Years of Accounts · Role Cards

    Briefing

    Students watch the intro video, review eight years of a listed software and services group with an unbroken record of earnings growth, and take on all three roles, checking the materiality threshold, the evidence available and the success criteria before any test is run.

  2. 2

    Stage 2 · 60 min

    Ratio Pack · Indicator Model · Transaction Sample · Tool Tips

    Screen & Test

    The work begins. Working as screening, the student plots earnings against cash and finds the year the two separate; as testing, runs five manipulation indicators and samples the revenue transactions behind them; as conclusion, writes down which of the results are evidence and which are only indications.

  3. 3

    Stage 3 · 55 min

    Management Responses · Contract Files · Audit Papers · Live Scores

    The Explanations

    Management answers every point, and the answers are plausible. Growth absorbs cash, a large contract was signed near the year end, a customer is slow rather than doubtful, and the auditor signed it. Two of the explanations survive testing and two do not.

  4. 4

    Stage 4 · 40 min

    Review Questions · Evidence Log · Outcome Report · Review Pack

    The Conclusion

    The conclusion is written. Students are asked which year the problem started, which indicator carried real weight, which management explanation they accepted and why, and whether their conclusion would survive being read by the company's lawyers.

  5. 5

    Stage 5 · No limit

    Winners · Completion Summary

    Debriefing

    Students review their own evidence log, compare conclusions across the cohort, revisit the tests that separated them and reflect on the feedback. Winners and the completion summary give you a structure for the discussion.

What the experience looks like

The student interface carries the accounts, the indicators and the evidence. The professor panel carries the timeline, the controls and every individual conclusion.

Screen

Students work year by year, with reported earnings, operating cash flow and the accrual between them side by side, and a written reason required wherever a year is flagged.

Tests

The explanation column is the one that matters. Two of the four hold up under testing, which is what makes the conclusion a judgement rather than a calculation.

Professor Controls

Your view. Adjust any stage timing, start or stop the session, and compare which year each student flagged with the conclusion they ended up writing.

Where it fits your syllabus

It works best as the session that turns ratio analysis into an investigation.

Teach before it

How to read an income statement and a cash flow statement. Accruals, manipulation indices and materiality are explained inside the activity.

Where it sits

Mid to late module, typically weeks six to eleven, once the statements have been covered.

What it sets up

Audit evidence and sampling, professional scepticism, whistleblowing, enforcement cases, and any assessment asking students to evaluate a set of published accounts.

The fraud detection course guide sets out where it sits in a full module.

What students get wrong

The three mistakes students make on this case, and what each one gives you in the debrief. Our simulations are designed around them: read the learning science behind it.

1

They find the gap and stop

The divergence between earnings and cash is where the work starts, not where it ends. Students who treat the chart as the conclusion cannot answer the first question management asks, which is whether anything they found is actually against the rules.

2

They accept the growth story

A fast-growing business genuinely absorbs cash into receivables and inventory, which is exactly why that explanation is offered and why it holds for four years. The test is whether the absorption is proportionate to the growth, and most students never run it.

3

They write more than they can prove

An indicator outside its range is a reason to look, not a finding. Students who write a conclusion the evidence does not carry produce something a company can dismiss in a sentence, which protects the problem rather than exposing it.

How to debrief it

The debrief runs itself. Every student sees their results, the cohort comparison and the decisions that produced them, with nothing for you to prepare. If you would rather lead the discussion, these questions work straight from a slide, and they use what your cohort actually did.

  • Which year did the problem start, and how did you date it?
  • Which indicator actually carried weight, and which was noise?
  • Which management explanation did you accept, and why?
  • Who in the room concluded differently from the same evidence?
  • Would your conclusion survive being read by the company's lawyers?

Assess the evidence and the restraint, not the verdict

Assessment is optional. Run the simulation ungraded as an applied activity, or use platform data as supporting evidence. Every student generates screening work, indicator results, transaction tests, a written conclusion and rationales. Because the simulation is single-player, every input belongs to one named student, so there is no group-work marking to untangle. All of it exports as CSV or PDF, per student, so you can assess reasoning rather than a result.

What professors can assess

  • Whether each indicator result was treated as a signal rather than a finding
  • Whether the conclusion is limited to what the evidence actually supports

How to interpret the score

  • Reaching the right verdict is not proof the work was sound; read the evidence log
  • Use the leaderboard for cohort comparison, not for grading

On generative AI: written rationales are exactly what marking teams now worry about. Because every rationale here is tied to a test the student ran inside the platform before the explanations arrived, the reasoning can be checked against the evidence rather than taken on trust.

Low risk to try with a class

Students rate it

93% of students rate Finsimco simulations Excellent, across more than 30,000 responses.

You are not on your own

Teaching notes, a setup and facilitation guide and a gameflow diagram come with it, and we support your first delivery directly.

No grading commitment

Run it ungraded the first time. Assessment is optional and can be added once you have seen how your cohort responds.

A bad session is recoverable

Pause or stop at any point and resume later without losing submitted data, so an overrun costs you a timetable slot, not the activity.
