Preparing for Due Diligence: A Founder's Financial Checklist

You've had a great pitch meeting. The partner is excited. They want to move forward with due diligence. This is where deals are made — or lost. Here's how to make sure your financial house is in order before investors start looking under the hood.

Clean Financial Statements

At minimum, you need GAAP-compliant income statements, balance sheets, and cash flow statements for the past two to three years (or since inception if you're earlier stage). Monthly granularity is expected. If your financials are on a cash basis, consider converting to accrual — it's what institutional investors expect.

Revenue Detail and Contracts

Investors will want to understand your revenue composition. Prepare a detailed breakdown by customer, by product line, and by contract type. Have your key customer contracts organized and accessible. If you have concentration risk — where one or two customers represent a large percentage of revenue — be ready to address it proactively.

Cap Table Accuracy

Your capitalization table needs to be perfect. Every option grant, every SAFE note, every convertible instrument should be documented and reconciled. Sloppy cap tables are a red flag that can derail deals. Use a cap table management tool and keep it current.

Tax Compliance

All federal, state, and local tax filings should be current. Any outstanding tax liabilities need to be disclosed. If you operate in multiple states, make sure your nexus analysis and sales tax filings are up to date. Tax surprises during due diligence erode trust quickly.

Financial Model

Your forward-looking financial model should be a connected three-statement model with clearly stated assumptions. Investors will stress-test your assumptions, so make sure they're defensible and grounded in actual business data. Include at least three scenarios: base, upside, and downside.

The Data Room

Organize everything into a virtual data room before investors ask. Categories should include corporate documents, financial statements, tax returns, contracts, IP documentation, employee agreements, and insurance policies. A well-organized data room signals professionalism and accelerates the timeline.

Start Early

The biggest mistake founders make is waiting until a term sheet is imminent to get organized. Start building your data room and cleaning up your financials at least three months before you plan to fundraise. The best time to prepare for due diligence is when you don't need to — it's much harder to do under the pressure of an active deal.
