What Happens During Due Diligence When Selling a Business?

Due Diligence: What to Expect When Selling Your Business

You’ve signed a Letter of Intent and the deal feels real. Now comes due diligence — the period when the buyer systematically verifies everything you’ve represented about your business. For many sellers, due diligence is the most stressful part of the sale process. Understanding what buyers look for, and how to prepare, will protect your deal and your sanity.

What Is Due Diligence?

Due diligence is the buyer’s investigation of your business before finalizing the purchase. It typically lasts 30–90 days and covers financial, legal, operational, and sometimes environmental or regulatory dimensions. The goal is simple: verify that what you said is true, and identify any risks that should affect the deal price or structure.

Financial Due Diligence

This is the most intensive area. Buyers (or their accountants) will:

• Reconcile your P&Ls to your tax returns for 3+ years
• Verify your SDE or EBITDA add-backs with documentation
• Analyze revenue by customer to check concentration
• Review accounts receivable aging for collectability
• Examine payroll records to verify employee costs
• Look for unusual expenses, missing income, or unexplained fluctuations
• Review bank statements and credit card statements

Any discrepancy between your represented financials and what buyers find in due diligence is grounds for a price reduction — or walking away entirely.

Legal Due Diligence

Buyers will review all contracts — customer, vendor, lease, and employment agreements. They’ll check for change-of-control clauses that could void contracts upon sale. They’ll verify licenses and permits are current and transferable. They’ll check for any pending or past litigation. They’ll review your corporate formation documents and ownership structure.

Operational Due Diligence

Buyers want to understand how the business actually runs. They may interview key employees (with your permission), visit the facility, observe operations, and ask detailed questions about processes, systems, and customer relationships. This is also where owner dependency becomes apparent — if you’re the only person who knows how to do certain things, buyers take note.

What Can Kill a Deal During Due Diligence?

The most common deal-killers discovered during due diligence in Florida business sales: revenue that doesn’t match tax returns, undisclosed customer losses (a major account that left after the LOI was signed), employee issues (workers comp claims, misclassified contractors), environmental compliance problems, lease issues (landlord won’t approve assignment), and undisclosed litigation.

How to Prepare for Due Diligence

The best thing you can do is treat due diligence as something to prepare for long before a buyer shows up. Organize your documents, reconcile your financials, resolve any known legal issues, and disclose potential problems proactively rather than letting buyers discover them. Surprises during due diligence erode trust and invite price reductions.

Your Advisor’s Role During Due Diligence

A skilled M&A advisor manages the due diligence process — coordinating document requests, filtering reasonable from unreasonable demands, and keeping the deal on track. They also help you respond to findings professionally rather than defensively. Ryan C. Winter guides St. Augustine business owners through due diligence from start to close.
