Due Diligence from the Owner’s Side: How to Prepare and What to Expect

By Matt Behrens, Managing Partner | 7 min read

“Due diligence feels like getting audited by the IRS while applying for a mortgage and interviewing for a job—all at the same time.”

That’s how one business owner described the growth capital due diligence process to me. I understood his frustration, but I also knew his experience could have been much smoother with better preparation.

After guiding hundreds of companies through due diligence, I’ve learned that the owners who prepare thoughtfully don’t just survive the process—they use it to demonstrate their professionalism and build stronger partnerships with investors.

What Due Diligence Really Tests

Most business owners think due diligence is about finding problems. It’s not. Professional investors expect to find issues—every business has them.

Due diligence tests three things:

How well do you understand your business? Can you explain your numbers, your market position, and your growth strategy clearly and consistently?
How do you handle pressure and complexity? The process reveals how you and your team perform under stress and scrutiny.
Are you the kind of partner we want for 3-7 years? Investors are evaluating your character, communication style, and problem-solving approach as much as your financials.

The companies that approach it as an opportunity to showcase their capabilities consistently get better terms and stronger partnerships.

The Four Pillars of Preparation

Financial Foundation

Get your books audit-ready 6 months before starting conversations.

This doesn’t mean you need a full audit, but your financials should tell a clear, consistent story. I’ve seen deals delayed by months because owners discovered their revenue recognition was inconsistent or their inventory accounting was unclear.

One software company we invested in had been recognizing multi-year contracts as revenue upfront. When we pointed this out, they panicked. But because we caught it early in due diligence, we helped them restate their financials properly, and the deal proceeded smoothly.

Key financial preparation steps:

Consistent accounting treatment across all periods
Clear reconciliation between tax returns and financial statements
Monthly financial closes (not just annual)
Detailed cash flow tracking and projections
Clean chart of accounts that makes sense to outsiders

Operational Documentation

Document your processes before you need to.

Growth capital investors want to understand how your business actually operates, not just how it performs. They’re evaluating whether your systems can handle 2-3x growth.

The best-prepared companies have:

Clear organizational charts with roles and responsibilities
Written procedures for key business processes
Customer contracts that are organized and easily accessible
Vendor agreements and key supplier relationships documented
Intellectual property properly registered and protected

A manufacturing company we partnered with had every process documented with video training materials. During due diligence, we could see exactly how they maintained quality and trained new employees. It demonstrated operational sophistication that justified a premium valuation.

Legal and Compliance Readiness

Clean up legal issues before they become deal-breakers.

Every business has some legal complexity, but some issues can kill deals or require expensive fixes during due diligence.

Address these common issues early:

Corporate structure and governance (board resolutions, stock records)
Employment agreements and non-compete provisions
Customer contract terms and renewal provisions
Intellectual property ownership and protection
Regulatory compliance in your industry
Any pending or potential litigation

We once had a deal almost collapse because the business owner had never formalized employment agreements with key employees. Two critical managers could leave with no notice and compete directly. We structured retention agreements as part of the deal, but it added complexity and cost.

Management Team Assessment

Present your team as your competitive advantage.

Investors aren’t just buying your current business—they’re betting on your team’s ability to scale it. Use due diligence to showcase your management depth and development.

Preparation strategies:

Have each key manager present their area of the business
Document succession plans for critical roles
Show evidence of team development and retention
Demonstrate decision-making processes and delegation
Present clear accountability and reporting structures

The Due Diligence Timeline

Weeks 1-2: Information Request You’ll receive a comprehensive information request. Don’t panic at the length—investors would rather ask for everything upfront than make multiple requests later.

Weeks 3-6: Document Review The investor team reviews your materials and develops follow-up questions. This is when good preparation pays dividends—organized companies move through this phase quickly.

Weeks 7-8: Management Presentations You’ll present different aspects of your business to the investment team. This isn’t an interrogation—it’s your chance to tell your story and demonstrate your expertise.

Weeks 9-12: Reference Calls and Site Visits Investors will speak with customers, suppliers, and industry contacts. They’ll visit your facilities and observe your operations firsthand.

Weeks 10-14: Final Due Diligence and Documentation Legal and financial due diligence concludes while final transaction documents are negotiated.

Common Mistakes That Create Problems

Treating it like an adversarial process. Due diligence should feel collaborative. If it doesn’t, you may have the wrong partner.

Hiding problems hoping they won’t be found. Professional investors will find issues. Address them proactively and present your solutions.

Not involving your team. Your key employees will be interviewed. Prepare them and make sure everyone tells the same story about your business and strategy.

Over-preparing presentations. Be thorough but natural. Investors want to see how you actually think and communicate, not how well you memorize scripts.

Neglecting day-to-day operations. Don’t let due diligence distract you from running your business. Performance decline during the process raises red flags.

What Good Preparation Achieves

A healthcare services company we invested in exemplified excellent due diligence preparation. They had:

Three years of audited financials with clear explanations for any anomalies
Documented processes for their clinical protocols and quality assurance
Strong management team with clear roles and development plans
Clean legal structure with all IP properly protected
Detailed market analysis showing their competitive positioning

The due diligence process took 8 weeks instead of the typical 12-14 weeks. More importantly, their preparation demonstrated the operational sophistication that justified a premium valuation and minimal investor oversight.

Red Flags from the Investor Side

Watch out for investors who:

Make unreasonable information requests or demand proprietary competitive information early in the process
Don’t provide clear timelines or keep extending deadlines
Send junior team members who can’t answer basic questions about their process
Focus exclusively on problems without discussing solutions
Seem more interested in finding ways to reduce valuation than understanding your business

The Partnership Test

Remember: you’re evaluating them as much as they’re evaluating you.

Good growth capital partners use due diligence to:

Understand how they can add value beyond capital
Identify potential challenges early so they can help address them
Build relationships with your management team
Develop a shared view of growth priorities and strategies

If the process feels punitive rather than collaborative, that tells you something important about the potential partnership.

Your Due Diligence Action Plan

6 Months Before: Clean up financials, document processes, address legal issues

3 Months Before: Organize all documents digitally, prepare management team, develop presentation materials

During Process: Maintain open communication, address issues proactively, keep running your business

Throughout: Evaluate the investor as much as they evaluate you

The Bottom Line

Due diligence doesn’t have to be painful. Well-prepared business owners find it validates their operational sophistication and builds stronger investor relationships.

The goal isn’t perfection—it’s demonstrating that you understand your business deeply, run it professionally, and can handle the complexities of partnership and growth.

Companies that approach due diligence as an opportunity to showcase their capabilities consistently achieve better outcomes and stronger partnerships.
