Flagship course
Ledger to Audit Trail
A six-module path from raw tax record audit app exports to query packs that survive partner review in United Kingdom practices.
Learning outcomes
What you can demonstrate afterwards
Entity-aware selects
Query multi-entity extracts without mixing VAT groups or payroll schemes.
Period locks
Build checks that respect locked periods and late postings your app still surfaces.
Evidence notes
Write short SQL comments and narrative notes that map to working-paper expectations.
Modules
Six steps through the trail
1. Export anatomy
Read headers, null patterns, and app-specific quirks in sample tax record audit app dumps.
2. Entity maps
Join company, scheme, and registration tables without inventing relationships.
3. VAT period cuts
Reconcile box totals to source lines and isolate late invoices.
4. PAYE & payroll extracts
Compare payroll runs to ledger postings and surface unmatched NI lines.
5. Exception ranking
Score false positives so juniors escalate fewer noise tickets.
6. Partner pack
Assemble a repeatable query bundle with retention-aware archives.

Compare seatsFAQ
Do I need production access to a tax record audit app?
No. We provide sample exports. Many learners practise on samples first, then adapt queries to their firm’s schema with mentor help.
Which SQL dialect do you teach?
Lessons use ANSI-leaning SQL with notes for PostgreSQL and SQL Server differences common in United Kingdom firms.
What is a real limitation of this course?
We do not cover every vendor-specific stored procedure. If your tax record audit app exposes proprietary functions, you will still need an internal SME to map those calls—our packs stop at portable SELECT/JOIN patterns.
Course reviews
“Module 3’s late-invoice query became our default pre-submission check. Still waiting on deeper CIS coverage in a future update.”
Short take from Leeds: “Partner pack templates saved me rewriting the same evidence note three times.” — Samira
