Due Diligence Checklist: Financial Documents VCs Request

What Is Due Diligence and Why It's Not Optional

Due diligence is the investor's process of verifying everything you've told them is true. They'll request financial documents, customer lists, cap tables, employee agreements, and more. This isn't punishment—it's standard for Series A and beyond. Founders who resist or stall due diligence trigger red flags. Investors assume you're hiding something. The best founders proactively organize due diligence materials months before fundraising so they can close quickly when offers come.

Series A fundraising typically includes 1-2 months of due diligence between LOI (letter of intent) and closing. If your materials are organized and accurate, closing takes 8-10 weeks. If you're scrambling to compile documents, explaining discrepancies, restating financials, closing takes 4-6 months. This difference is real and expensive. Every month of extended due diligence is a month you can't scale and investors get nervous about delays.

The Financial Documents Investors Always Request

Expect requests for: (1) Monthly P&L statements for the past 24 months (or since founding if less than 24 months), (2) Monthly cash flow statements, (3) Monthly balance sheets, (4) Cap table (fully diluted equity ownership), (5) Detailed revenue breakdown by customer and contract, (6) Customer cohort analysis showing retention and expansion, (7) Expenses by category for past 12 months with explanations for large items, (8) Assumptions documentation (how you calculated key metrics), (9) GAAP vs Cash accounting reconciliation, (10) Detailed budget vs actual for past 6 months.

Before you think "that's a lot," remember: this is table stakes for Series A. If you haven't been maintaining these internally, start now. Use a bookkeeper or accountant who keeps these statements clean. Most founders are shocked at how much time due diligence takes because they never organized their financials. Don't be that founder.

The Cap Table: Your Most Important Document

Your cap table is a detailed ownership record showing every share class, every shareholder, and all options/vesting. Investors will scrutinize this obsessively. They want to understand: Who are all your shareholders? What were the terms of each investment? Are any shareholders adversarial? Is the option pool appropriately sized? Are there any off-balance-sheet obligations?

Your cap table must be 100% accurate. Any discrepancies trigger deal delays or renegotiation. Many founders maintain sloppy cap tables, then spend weeks correcting them during due diligence. Use cap table management software (Carta, AngelList Cap Table, etc.) from day one. When you accept your first angel investment, create a cap table immediately. Each subsequent investment updates it. By Series A, your cap table is a document, not a mystery.

Revenue Documentation: The Devil Is in Details

Investors want to understand exactly where your revenue comes from. You'll provide: (1) Customer list with customer name, monthly/annual revenue, contract start date, contract end date, (2) For top 20% of customers (often 80% of revenue), copies of contracts or at least term summaries, (3) Monthly cohort analysis showing revenue by month acquired, retention by month, (4) Any revenue concentration risk (if 30% comes from one customer, they'll notice and worry), (5) Explanation of any large one-time revenue (consulting projects, etc.).

If you have $500K ARR and claim 10% monthly churn, investors will check. They'll look at January cohort: acquired 50 customers at $1K/month each. February: did 45 of them renew (10% churn)? By March should be 40.5? Build a simple spreadsheet showing this cohort-by-cohort. Transparency accelerates due diligence. Ambiguity slows it down.

Expenses and Assumptions Documentation

Large expenses need explanations. "Equipment purchases $50K" is insufficient. "Server hardware $50K purchased in Q4 for processing infrastructure" is better. "Server hardware $50K, expected to service 5x current customer base, part of Series A deployment plan" is best because it explains the strategic intent. Investors worry expenses indicate problems or mismanagement.

For key assumptions (churn rate, CAC, LTV, gross margin), provide documentation showing how you calculated them. "Churn calculated as: (customers at start of month - customers at end of month) / customers at start of month." If your churn calculation is different from standard definitions, explain why. Investors want confidence that your metrics are calculated correctly and consistently.

Walkthrough Documents: Explaining Your Story

Beyond raw numbers, provide written explanations of your financial story: (1) A 2-3 page financial overview explaining your revenue model, unit economics, path to profitability, (2) Key assumptions and how they support your projections, (3) Historical performance and how actual vs forecast compares, (4) Strategic initiatives and their financial impact (hiring, new product, new market), (5) Use of proceeds from any prior fundraising and milestones achieved.

This narrative helps investors understand the "why" behind the numbers. If your burn increased from $100K to $150K month-over-month, investors will read this and see: "Burn increase driven by 3 new engineer hires in preparation for Series A customer onboarding. Expect burn to stabilize at $145K as engineers ramp. New hires anticipated to increase revenue growth from 5% to 12% monthly starting Month 4." Context prevents alarm and shows planning.

Legal and Compliance Documents

Beyond financials, prepare: (1) Certificate of incorporation and bylaws, (2) Cap table with supporting documentation (SAFEs, convertible notes, equity agreements), (3) Employee agreements (offer letters, RSA/option agreements), (4) Customer agreements (NDA, terms of service, any special contracts), (5) Vendor agreements for major vendors, (6) IP assignment agreements (employees have assigned IP to company), (7) Insurance policies, (8) Any litigation (lawsuits, disputes). Most of this isn't financial, but it's all due diligence.

Organizing and Presenting Efficiently

Create a dedicated data room (secure online folder) with organized documents. Use folders: (1) Financial Statements, (2) Cap Table and Equity, (3) Revenue and Customer Data, (4) Expense Reports and Assumptions, (5) Legal and Compliance. Number documents clearly. Create a summary index explaining what's in each folder.

When you send documents to investors, send a cover memo explaining the contents: "Hi [Investor]. Here are the requested due diligence materials. Financial statements are in Folder 1, organized by month. Cap table is in Folder 2 with detailed term sheets. Revenue breakdown is in Folder 3. Please let me know if you need clarification on anything." This professionalism accelerates due diligence and signals financial competence.
