Modules

Curriculum path

  1. Control universe mapping

    Define AP invoice intake, vendor master, AR credit, and cash application assertions before opening the app.

  2. Sampling that respects volume

    Choose judgmental and statistical samples that still leave capacity for surprise testing.

  3. Three-way match exceptions

    Work PO, receipt, and invoice mismatches through the financial auditing app’s exception queue.

  4. Vendor master change testing

    Trace bank detail edits, dual approval evidence, and dormant vendor reactivation.

  5. AR aging & credit notes

    Validate aging buckets, unauthorized write-offs, and credit-note authorization chains.

  6. Cash application integrity

    Reconcile lockbox dumps to customer accounts and document unapplied cash reasons.

  7. Finding language & remediation

    Draft issues that operations can action, with severity that mirrors Korean audit committee expectations.

  8. Close-week dry run

    Timed lab simulating a compressed testing window before management sign-off.

Learner notes

“Module 5 on AR aging finally connected our credit-note workflow to what the app stores — we stopped rebuilding screenshots in PowerPoint.”

“Useful, though the vendor master lab assumes dual-approval screens some mid-market ERPs simply do not have.”

FAQ

Common questions

Do we need our own financial auditing app licenses?

Cohorts use Edgedatasys lab tenants. You may optionally mirror steps in your production tool afterward, but it is not required during class.

Is the course only for Big Four alumni?

No. Shared-service analysts, SOX coordinators, and first-year internal auditors routinely join. We assume familiarity with invoices and aging reports, not with prior audit firm experience.

What is a real limitation of this program?

We do not cover treasury or payroll controls. Teams hoping for end-to-end SOX mapping across every process will need a separate curriculum — this flagship stays deliberately inside AP and AR.

Language of instruction?

Sessions run in English with Korean glossary sheets for control terms used in local filings. Office hours can accommodate Korean questions.
