“Module 4’s cutoff checklist caught a weekend posting window our billing vendor never documented. We still struggle with multi-entity FX, but the rematch log is finally readable.”Min-seo Park · Internal audit, Seoul SaaS group

Ledger Sync Audit Foundations
A paced curriculum that walks from export hygiene to audit-ready working papers—built around real app-to-ledger mismatches, not abstract theory.
Map, sample, evidence, and close the gap
Learn how to document field-level reconciliation between operational apps and the general ledger, including timestamp drift, currency rounding, and deferred postings common in Korean mid-market stacks.
Why teams enroll
Sync validation that survives an audit review
We focus on the awkward middle: when the CRM invoice, the billing app, and the ledger all claim to be right.
-
Export contracts you can test
Define expected columns, cutoffs, and hash checks so every rematch starts from a known baseline.
-
Sampling that explains itself
Build strata for high-value, high-velocity, and high-risk flows—then record why each sample was chosen.
-
Working papers reviewers accept
Templates for exception aging, owner assignment, and residual risk notes that fit Korean statutory review habits.
