Build a Semi-Automated Credit Memo Workflow with Claude
What This Does
Combines Excel spreading with Claude for narrative generation into a repeatable workflow that produces a near-complete credit memo first draft for a standard C&I deal in 30-45 minutes. You handle the judgment and approval; Claude handles the writing.
This is a process design. You'll be building your own system, not installing software.
Before You Start
- You have Claude.ai Pro
- You have a standard credit memo template in Word
- You have your spreading model in Excel
- Confirm data governance policy: what borrower information can you upload?
The Workflow
Phase 1: Spread and Calculate (15-20 minutes, Excel)
Use your existing spreading model. Calculate all ratios before moving to Claude. Key outputs you'll need:
- 3-year income statement (revenue, EBITDA, net income)
- Key ratios for each year (DSCR, Debt/EBITDA, current ratio, gross margin)
- Balance sheet snapshot (total assets, total debt, equity)
- Stress test results (1-2 scenarios)
Create a "Claude Input Summary" tab in your Excel model:
- One table per section: income statement, ratios, stress test
- Add a "Narrative notes" column: brief analyst observations about each metric
Phase 2: Generate Narrative (10-15 minutes, Claude)
Open your Credit Analyst Claude Project (or a fresh Claude Pro conversation). Use a master prompt that produces all sections at once:
I'm preparing a credit memo. Generate professional memo sections based on the data and notes below. Use formal bank lending language throughout.
**DEAL SUMMARY:**
- Borrower: [name] | Industry: [industry] | Request: $[X]M [type]
- Purpose: [use of proceeds] | Term: [X years] | Rate: [rate]
- Collateral: [primary collateral] | Guarantors: [names]
**FINANCIAL DATA (3-year spread):**
[Paste your income statement table from the "Claude Input Summary" tab]
**KEY RATIOS:**
[Paste ratio table]
**STRESS TEST RESULTS:**
[Paste stress scenarios and outcomes]
**ANALYST NOTES:**
[Paste your narrative notes column: "Revenue decline in FY2022 due to customer loss; recovered in FY2023 with new contract" etc.]
Generate the following sections:
1. Company Overview (2 paragraphs)
2. Financial Analysis (3-4 paragraphs interpreting the trends)
3. Collateral Analysis (1-2 paragraphs)
4. Stress Test Analysis (1-2 paragraphs)
5. Key Risks and Mitigants (bullet list, 3-4 items)
6. Recommendation (1 paragraph, recommend approval)
Phase 3: Assemble and Edit (10-15 minutes, Word)
Paste Claude's output sections into your bank's Word credit memo template. Edit:
- Bank-specific terminology and policy references
- Any factual corrections
- Your personal assessment of deal quality
- Loan committee presentation order
Add sections Claude can't write: deal approval authority routing, rate sheet, and your compliance checklist.
Tips for Scaling This
Build a prompt library: Save your master prompt as a text file. Keep variants for:
- C&I standard (this workflow)
- CRE term loan (adds market analysis section)
- SBA 7(a) (adds program eligibility section)
- Annual review (different structure than new money)
Time yourself: First run will take longer as you adjust the workflow. After 5-6 deals, this should be sub-45 minutes for a standard C&I package.
Maintain quality control: Add a "Claude-drafted section" note in the Word document revision history. Your senior credit officer should know which sections were AI-assisted. Remove these notes before final submission.
What This Doesn't Replace
- Your credit judgment about whether to approve
- Covenant negotiation
- Relationship management
- Any sections requiring your personal attestation (credit officer signature lines)
This workflow assists drafting. All credit decisions require qualified credit officer review and approval.
