Flagship course
Billing Change Control Audit
A practitioner course on financial auditing guidance for change management controls over billing platforms — from ticket intake to post-release invoice checks.
Who it is for
Internal auditors, SOX testers, billing operations leads, and external advisors who need to evaluate how rating engines, plan catalogs, and invoice rules are changed without relying on vague ITGC language.
Learning outcomes
- Map a billing release path including silent configuration channels
- Design samples that weight revenue impact, not just ticket volume
- Critique dual-control design when automation deploys changes
- Draft findings that cite invoice and credit effects with clear criteria
- Specify rollback evidence that would survive partner review
Modules
Seven weeks of structured pressure-testing
- Module 1 — Billing change taxonomy Separate catalog edits, rating logic, tax tables, and credit rules. Build a scope memo your engagement lead will actually keep.
- Module 2 — Authorization & dual control Trace who can request versus who can release. Cover emergency paths, shared inboxes, and service identities.
- Module 3 — Test evidence that proves billing behavior Move beyond “QA signed off” to invoice fixtures, credit memos, and mid-cycle plan switches.
- Module 4 — Release identity & version pins Connect production billing periods to the rate package that was live — including hotfixes that never reached CAB.
- Module 5 — Monitoring after go-live Define signals that reveal silent revenue drift within the first billing cycles.
- Module 6 — Rollback & customer remediation Rehearse incomplete reversals and document what “done” means when invoices already went out.
- Module 7 — Finding workshop Write and peer-critique observations using your redacted tickets. Leave with a reusable template.

FAQ
Straight answers, including limits
No. The course sharpens how you evaluate billing change controls; it does not certify you under any Korean or international standard, and it is not a substitute for your firm’s methodology.
We use composite patterns from subscription rating engines, telecom-style mediation, and mid-market ERP billing modules. We do not teach a single vendor’s UI click-path.
We do not deeply cover tax engine configuration or cross-border VAT determination. If your primary risk sits in tax determination tables, you will need a complementary tax specialist review — our materials only touch tax tables when they ride along in the same change ticket as rating logic.
Only redacted artifacts. Remove customer identifiers, exact amounts if sensitive, and anything your engagement letter forbids sharing with a training provider.
Course reviews
From people who finished the finding workshop
Module 4’s version-pin exercise caught that our “production” export job still pointed at a staging catalog for one product family. Short review, long impact.
★★★★☆
Strong on dual control. I wanted more screenshots from legacy mainframe rating — the composite diagrams were clear, just not my stack. Still recommended to my team.
