Controller-level Balance Sheet deep analysis from QuickBooks Online. Pulls current and prior period BS, runs 3-month rolling averages, GL drill-down for material changes, and generates a 7-tab Excel workbook with actionable findings. Covers working capital health, current ratio flags, equity rollforward, and common-size vertical analysis.

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 pl-deep-analysis.py
Multi-entity consolidations — this is a single-entity BS pipeline
Real-time balance changes (it's snapshot-based, not bank-feed)

Usage

# Current month-end vs. auto prior month-end
python3 scripts/pipelines/bs-deep-analysis.py \
  --slug sb-paulson --current-end 2026-03-31

# Explicit prior period
python3 scripts/pipelines/bs-deep-analysis.py \
  --slug sb-paulson \
  --current-end 2026-03-31 --prior-end 2026-02-28

# Skip GL drill-down (faster, no vendor-level detail)
python3 scripts/pipelines/bs-deep-analysis.py \
  --slug sb-paulson --current-end 2026-03-31 --skip-gl

# Custom output directory
python3 scripts/pipelines/bs-deep-analysis.py \
  --slug glowlabs --current-end 2026-03-31 --out ~/Desktop/reports

# QBO sandbox
python3 scripts/pipelines/bs-deep-analysis.py \
  --slug sb-paulson --current-end 2026-03-31 --sandbox

Arguments

Argument	Required	Description
`--slug`	✅	QBO company slug (must be connected in qbo-client)
`--current-end`	✅	As-of date for current BS (YYYY-MM-DD)
`--prior-end`	❌	Prior period as-of date (auto = prior month-end)
`--skip-gl`	❌	Skip GL drill-down (faster)
`--out`	❌	Output directory (default: ~/Desktop)
`--sandbox`	❌	Use QBO sandbox environment

What It Pulls from QBO

Balance Sheet (as-of) — current period
Balance Sheet (as-of) — prior period
Balance Sheet (as-of) — 3 prior month-ends for rolling averages
General Ledger — current period GL for flagged accounts (unless --skip-gl)
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 .cache/bs-deep-analysis/{slug}.json

Excel Output — 7 Tabs

Dependencies

pip install openpyxl

Pipeline	File	When to Use
P&L Deep Analysis	`pl-deep-analysis.py`	Income statement controller review
Financial Ratios	`financial-ratios.py`	Full ratio suite (uses BS data)
BS Deep Analysis	`bs-deep-analysis.py`	This pipeline — balance sheet focus

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)
--skip-gl 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)
