Vendor concentration drift YoY

The board deck is due Friday

A company ledger star schema with 5 tables, 5,500+ rows, and planted reconciliation issues. Duplicate vendors that inflate spend rankings, un-posted journal entries hiding from totals, inconsistent account-type casing that splits your GROUP BYs, refund leakage, and duplicate payments that quietly skew vendor risk.

The SQL-first finance role at tech, fintechs, and modern CPG: variance bridges, gross-margin decomposition, running cash burn, YoY revenue growth, and board-ready P&L rollups against a realistic ledger with planted reconciliation issues. Also a strong foundation for traditional FP&A — the SQL patterns are identical, but entering corporate FP&A usually wants CPA or CFA alongside. caseSQL targets the technical variant first.

Answer questions from the CFO, FP&A Manager, Treasury Analyst, Controller, and Senior Auditor — MBR variance packs, budget attainment, revenue seasonality, cash burn, and vendor concentration.

Finance Deliverable Scenarios

Duplicate vendors, un-posted journal entries, inconsistent account-type casing, refund leakage, and duplicate payments — the reconciliation traps that quietly wreck a variance narrative.

Messy Ledger Data

A vs B vs F vs PY variance, gross margin decomposition, running cash burn, YoY revenue growth, percentile ranking, cohort onboarding, and late-posting analysis.

Finance Analyst SQL Skills

Every mission maps to a real Finance Data Analyst task — MBR packs, QBR decks, CFO-ready variance bridges, and the SQL Stripe / Meta / Google finance teams actually screen for.

Portfolio-Ready Skills

The CFO wants the board deck.
