BS Deep Analysis

What This Skill Does

Controller-level Balance Sheet deep analysis from QuickBooks Online. Mirrors the P&L Deep Analysis pattern but for the balance sheet — pulls current + prior period BS, runs 3-month rolling averages, GL drill-down for material changes, and generates a 7-tab Excel workbook with actionable findings.

Use when:

• - Monthly close deliverable needs a BS review (not just a P&L comparison)
• Client needs working capital health check or current ratio flag
• Equity rollforward reconciliation is needed for a close
• Material balance changes on cash, AR, inventory, or debt need narrative explanation
• Common-size (vertical) analysis is required for a lender or board report

NOT for:

• - Cash flow statement analysis — use a dedicated CF pipeline
• P&L variance analysis — use INLINECODE0
• Multi-entity consolidations — this is a single-entity BS pipeline
• Real-time balance changes (it's snapshot-based, not bank-feed)

Arguments

What It Pulls from QBO

1. 1. Balance Sheet (as-of) — current period
2. Balance Sheet (as-of) — prior period
3. Balance Sheet (as-of) — 3 prior month-ends for rolling averages
4. General Ledger — current period GL for flagged accounts (unless --skip-gl)
5. P&L — current period net income for equity rollforward

Analysis Modules

1. Horizontal Analysis (Period-over-Period)

• - Every BS line: prior → current → $ change → % change
• Material threshold: ≥$2,500 absolute OR ≥10% change rate
• Flagged accounts sorted by absolute dollar change

2. Vertical Analysis (Common-Size)

• - Every BS line as % of total assets
• Prior period % vs. current period %
• % point change highlights structural shifts

3. 3-Month Rolling Averages

• - Pulls 3 prior month-end BS snapshots
• Per-account rolling average as trend baseline
• Rolling delta and rolling % vs. current balance

4. GL Drill-Down

• - Transaction-level detail for all flagged accounts
• Vendor/payee aggregation: top contributors by dollar
• Max 50 transactions per account (configurable via GL_MAX_ROWS_PER_ACCOUNT)

5. Working Capital Deep Dive

• - Current assets vs. current liabilities decomposition
• Current ratio, quick ratio, cash ratio
• WC delta decomposed: cash change, AR change, inventory change, AP change
• Health classification: HEALTHY / WATCH / CRITICAL

6. Debt Schedule Analysis

• - Short-term vs. long-term debt split
• D/E ratio and D/A ratio
• ST concentration warning: flags if ST > 60% of total debt
• Leverage risk classification: LOW / LOW-MEDIUM / MEDIUM / HIGH

7. Equity Rollforward

Beginning Equity
+ Net Income
− Distributions / Owner Draws
+ New Contributions / Paid-in Capital
= Computed Ending Equity
vs. Ending Equity per BS (reconciling difference flagged if ≥ $500)

• - Retained earnings bridge separately
• Reconciling difference investigation prompt

8. Controller Findings

• - Narrative: "Cash decreased $45K because AP payments of $60K exceeded collections of $15K"
• Urgency-tagged: HIGH / MEDIUM / LOW
• GL vendor attribution embedded in findings

9. Action Proposals

• - Specific recommended actions per finding
• Urgency-ranked: HIGH → MEDIUM → LOW
• Categories: LIQUIDITY, CASH MANAGEMENT, COLLECTIONS, INVENTORY, DEBT MANAGEMENT, LEVERAGE, EQUITY INTEGRITY, BALANCE SHEET

10. CDC (Change Data Capture)

• - Compares current BS flat map vs. prior run cache
• Tracks: new accounts, removed accounts, balance changes
• Cache saved to INLINECODE10

Notes

• - All math uses Python Decimal — no float rounding errors
• GL account names must match BS account names for drill-down attribution (QBO may use slightly different names between reports)
• Prior month-end is auto-calculated if --prior-end is omitted (always safe for monthly close)
• INLINECODE16 reduces runtime significantly; use for quick runs when vendor detail is not needed
• CDC cache is per-slug; running for a new slug always starts fresh (first run snapshot only)
