The aging module forced us to retire a “miscellaneous” reason code that had been hiding FX fee drift for months. Mild caveat: the homework load in week four is heavy if your day job is already peak volume.
Flagship course
Ledger Break Investigation
A six-week program for analysts and audit partners who must explain every unmatched transaction in a fintech ledger — and leave a trail regulators can follow.
Outcomes

- Build a defensible match-key map across wallet, card, and internal transfer rails.
- Age exceptions with root-cause tags that map to control owners.

Notes from recent seats
★★★★☆
Evidence packaging finally gave our audit partners a template they stopped rewriting. I still wish Module 2 had one more remittance-corridor example.
FAQ
Do I need an accounting degree?
No. You need familiarity with your ledger exports and a willingness to read processor file specs. We assume Excel or SQL comfort, not CPA credentials.
Is this a tool training course?
No. We stay tool-agnostic. Concepts transfer to in-house matchers, vendor platforms, and spreadsheet bridges.
What is a real limitation of this course?
We do not certify you against a specific Korean regulatory examination, and we cannot review live production data containing personal information. Labs use synthetic datasets; applying methods to your stack remains your team’s responsibility.
