What is Finance Due Diligence for Startups

Finance due diligence is a standard part of the venture capital fundraising process, especially as startups raise later rounds. It becomes critical at Series A or Series B, although some seed investors conduct financial checks too. Whenever a company is acquired or exits through M&A, the acquiring party will also conduct financial due diligence.

This guide breaks down the key components of finance due diligence and what startup founders need to know to prepare.

What is Finance Due Diligence?

Finance due diligence is a deep dive into a company’s financial performance. It includes reviewing financial statements, business practices, and operating metrics to understand the company’s financial health and outlook.

It’s not unusual for large companies to run a light financial check before buying a software solution from a startup. These buyers want to know the startup is stable enough to support the product over time.

For startups, financial due diligence is particularly relevant when:

• Raising venture capital
• Preparing for an acquisition
• Exploring a merger
• Considering strategic partnerships

The Role of Financial Due Diligence in Venture Capital

When startups approach VCs, financial due diligence helps investors assess risk and confirm the accuracy of financial statements, cash flow, and overall financial health. It ensures the startup’s numbers are reliable, the business is compliant, and there are no hidden liabilities. Venture debt lenders also review similar information before providing funding.

One Area VCs Focus On

Venture capitalists place significant weight on a startup’s financial projections and growth model. While they do care about historical data, they’re primarily looking for signals of future potential. Sales efficiency metrics, marketing ROI, and payback periods are areas that tend to receive closer scrutiny.

Key Areas of Focus in Financial Due Diligence

1. Financial statements 
2. Cash burn and runway 
3. Revenue recognition methods 
4. Cost structure 
5. Cap table and past financing 
6. Tax filings and compliance 
7. Major contracts and obligations 
8. KPIs and operating metrics 
9. Projections and growth assumptions

We’ve outlined these in more detail in our finance due diligence checklist.

How Financial Diligence Changes by Stage

In Silicon Valley and similar ecosystems, diligence gets more intensive as a company progresses:

• Pre-Seed/Seed: Focus is on potential, founders, and basic compliance 
• Series A: Financial projections and early traction take center stage 
• Series B: Deeper analysis into scale, margins, and customer metrics 
• Series C+: Full audits, system checks, and third-party reviews become standard

Fraud Detection in Later-Stage Due Diligence

As the stakes rise, VCs get more serious about uncovering risks. They often bring in third-party experts to review statements and internal controls.

They look for:

• Manipulated numbers or misleading line items 
• Undisclosed liabilities in contracts 
• Unethical or risky practices 
• Volatile revenue streams 
• Overly aggressive assumptions in projections

Third-party law firms and accountants may be involved to verify claims and financials.

Best Practices for Startups Preparing for Financial Due Diligence

1. Keep Financial Records Clean and Updated

Make sure your books are accurate and easy to follow. Maintain:

• Income statements 
• Balance sheets 
• Cash flow statements 
• Tax returns 
• Forecasts 
• A clear cap table

2. Build Reliable Financial Systems

Use connected accounting software, reconcile accounts regularly, and track expenses closely. Some early-stage companies overlook this, but having solid systems in place early helps you avoid problems later.

Tools to consider:

• Accounting software linked to bank and credit feeds 
• Expense tracking solutions 
• Clear financial policies and controls

3. Bring in the Right Advisors

You don’t need a full-time CFO early on, but working with a good startup accounting partner and legal team makes diligence much smoother. Choose firms that have supported other startups through fundraises.

4. Create a Data Room

Store all key documents in a centralized digital folder. Most startups use Google Drive, Box, or Dropbox. Include:

• At least three years of financials (if available) 
• Tax returns 
• Major agreements 
• Cap table 
• IP documentation

5. Be Transparent with Investors

VCs don’t appreciate surprises during diligence. If something could raise questions, bring it up early and be ready to explain. It’s better to address potential issues upfront than to get caught off guard later.

Be prepared to walk through:

• Past challenges or pivots 
• Financial risks 
• Market trends 
• Competitive positioning 

What to Expect During the Financial Diligence Process

1. Initial Information Request

Investors usually start with a list of data they need. Expect to provide:

• Financial statements 
• Customer and revenue data 
• KPI trends 
• Compliance documents

Some will start small and ask for more over time. Others may ask for a lot up front. If you don’t have something, explain why. For example, if you don’t track churn yet due to having only a few customers, that’s reasonable—but let the investor know.

2. In-Depth Review

Once documents are shared, the investor’s team will:

• Analyze margins and cash flow 
• Evaluate runway and projections 
• Examine acquisition costs and lifetime value 
• Look at how financial performance aligns with your story

3. Management Discussions

Investors typically schedule meetings with the team to:

• Clarify questions from the financial review 
• Understand the company’s strategy 
• Discuss projections 
• Evaluate founder competence 

4. Third-Party Checks

Especially in later rounds, investors may verify information through:

• Customer calls 
• Vendor confirmations 
• Legal and regulatory reviews 
• Outside accountants or specialists

Common Challenges in Financial Due Diligence

1. Incomplete Financial Records

Missing or messy records can delay or derail a deal. Your cap table, payroll data, and historical numbers should be accurate and easily accessible.

2. Cash-Based Accounting

Many early founders use cash accounting, which records revenue when it hits the bank. VCs typically want to see accrual-based accounting. If you’re not there yet, consider upgrading before you raise.

3. Complex Revenue Models

Subscription-based or usage-based pricing can complicate revenue recognition. Make sure your policy is clear and applied consistently.

4. Unrealistic Projections

Venture investors expect growth, but your forecasts still need to make sense. Avoid showing huge growth without adding corresponding expenses; it usually signals inexperience.

5. Tax Problems

Late filings or poor tax hygiene will raise red flags. VCs don’t want their money going toward fixing past issues. Get a qualified tax advisor early to help keep everything in order.
