Why Most Owners Are Unprepared for Buyer Due Diligence
Due diligence is where deals go to die. After months of negotiation, after signing a Letter of Intent, after telling your spouse it's happening — the buyer's team opens the books and starts asking questions. And for 30–40% of deals that reach this stage, the deal falls apart.
The reason is almost always the same: the business wasn't prepared for the level of scrutiny that modern buyers bring. What felt like "good enough" when you were running the business becomes painfully inadequate when someone is writing a multi-million dollar check based on your numbers.
What Buyers Actually Request in Due Diligence
If you've never been through a due diligence process, the request list will shock you. A typical buyer will ask for 100–200+ specific documents and data points. Here's a sample of what's coming:
Financial Due Diligence
- Three years of audited or reviewed financial statements
- Monthly P&L, balance sheet, and cash flow statements (trailing 24 months)
- Revenue by customer, by product line, by month
- Accounts receivable aging report
- Detailed list of all add-backs and adjustments to EBITDA
- Tax returns (3+ years)
- Working capital analysis
Operational Due Diligence
- Organizational chart with roles and compensation
- Employee agreements, non-competes, and benefit plans
- Key customer contracts and renewal terms
- Vendor and supplier agreements
- Standard operating procedures (SOPs)
- Technology stack and IP documentation
Legal Due Diligence
- Corporate formation documents
- All pending or threatened litigation
- Regulatory compliance records
- Real estate leases
- Insurance policies
- Environmental assessments (if applicable)
The Three Steps to Surviving Due Diligence
Step 1: Build Your Transaction Team Early
You need three people in your corner before you go to market:
- An M&A attorney — Not your business attorney. Not your real estate attorney. An attorney who specializes in mergers and acquisitions. This person will save you from deal structures that look good on paper but cost you in practice.
- A CPA who understands transactions — Your regular accountant files your taxes. A transaction-oriented CPA prepares your financials to withstand a quality of earnings review. There's a massive difference.
- Potentially a sell-side advisor — Depending on deal size and complexity, a good M&A advisor can manage the process, create competition among buyers, and keep you focused on running the business while the deal progresses.
Step 2: Start Your Due Diligence Checklist Now
Don't wait until a buyer asks for documents. Start assembling the due diligence package 6–12 months before you plan to go to market. The act of assembling it will reveal gaps you didn't know existed — missing contracts, undocumented processes, financial inconsistencies.
Finding these issues early is a gift. Finding them during due diligence is a disaster. When a buyer discovers something you didn't disclose — even if it's not intentional — their trust erodes. And once trust erodes, the deal either dies or the terms change dramatically in the buyer's favor.
Step 3: Learn From Owners Who've Been Through It
The single best thing you can do before entering a sale process is talk to other owners who've recently sold. Not owners who tried and failed — owners who completed a transaction. Ask them:
- What surprised you most about due diligence?
- What do you wish you'd prepared earlier?
- Where did the buyer push back hardest?
- What almost killed the deal?
Their answers will be more valuable than anything you read online. Every deal is different, but the patterns repeat.
The Importance of Financial Certainty
Above everything else, buyers need to trust your numbers. The quality of earnings (QoE) report is the single most important document in any deal process. It's an independent verification of your financial performance, and it will either confirm your story or contradict it.
If your QoE comes back clean, the deal moves forward with confidence. If it reveals material discrepancies — revenue recognition issues, inflated add-backs, hidden liabilities — the buyer either retracts the price, restructures the terms, or walks away.
"The goal isn't to survive due diligence. The goal is to have the buyer come out of due diligence more excited about the deal than when they went in."
Where Deals Actually Break
In my experience, deals break in due diligence for three primary reasons:
- Financial surprises. The numbers don't match the story. EBITDA comes in lower than presented. Revenue isn't as recurring as claimed.
- Undisclosed risks. A major customer is leaving. There's pending litigation. A key employee is about to quit. Anything the buyer discovers that you didn't disclose becomes evidence that there might be more you're hiding.
- Operational fragility. The business looks great from the outside but crumbles under inspection. No SOPs, no documented processes, no management team beyond the owner.
