📊 Balance Sheet Analysis

Quickly analyze a balance sheet to produce a summary note, key ratios, and alert points.

Balance sheet analysis is a time-consuming and repetitive activity in accounting firms. For each client file, you must produce ratios, comparisons year-over-year and two-year comparisons, alert points, and recommendations. AI allows reducing from 1-2 hours to 15-25 minutes per file, provided a solution respects professional confidentiality. This guide presents the rigorous workflow combining analysis generation and human validation.

Step-by-step Workflow
1
Prepare pseudonymized data or use a secure LLM

Either anonymize the balance sheet (replace company name, SIREN number) or use ChatGPT Enterprise / Claude for Work which don't store data. Without this precaution, it's a breach of professional confidentiality.

2
Submit structured data

Paste balance sheet assets/liabilities and income statement with values for current year and prior year (ideally two prior years as well). The more structured the data, the better the analysis.

3
Generate ratios and alerts

Request: structure ratios (working capital, operating cycle, cash), management ratios (inventory turnover, receivables, payables), profitability ratios (gross margin, EBITDA, net income). Identify alert points.

4
Compare with industry benchmarks

If you have access to benchmarks (Banque de France, Diane, Pappers Pro), compare to position the company in its sector. AI can estimate if you provide the sector.

5
Draft the summary note

Have it produce a clear one-page note: overall situation, strengths, alert points, recommendations. Always validate every figure cited before sending to client.

Frequently asked questions
Can AI correctly calculate ratios?

For simple calculations: yes 95% of the time. For chained calculations or those requiring subtle rounding: always verify with a calculator or Excel. Code Interpreter (ChatGPT) or Claude with Python tool are more reliable for precise calculations.

How to guarantee balance sheet confidentiality?

Three options: (1) pseudonymize before sending (replace company name, SIREN, exact amounts with proportions), (2) use ChatGPT Team/Enterprise or Claude for Work (no storage), (3) self-host an open source LLM (Mistral, Llama) for most sensitive files.

Can AI replace a statutory auditor?

For analytical production and initial alerts: it accelerates significantly. For certification responsibility: no, that's a statutory auditor's core mission that cannot be delegated to a machine. AI is a tool, not a signer.

Can AI generate projected balance sheets?

Yes, based on clear assumptions (revenue growth, margins, operating cycle). AI quickly produces multiple scenarios (pessimistic/median/optimistic). Always validate business coherence with client before submitting.
