Watch: What Happens During Due Diligence (And How to Survive It)

8 min

A dental practice owner in the Austin metro accepted an offer at $1.85 million. The LOI was signed. The champagne was figuratively uncorked. Then due diligence started — and for the next 45 days, the owner felt like a defendant at trial.

Every expense questioned. Every patient record analyzed. Every contract reviewed by the buyer's attorney. Three rounds of follow-up questions. Two tense phone calls about discrepancies in the accounts receivable aging report. And a moment — around day 30 — when the owner was convinced the deal was dead.

It wasn't dead. It closed. At $1.82 million — a $30,000 adjustment from the original offer, negotiated based on findings during due diligence. The owner walked away with a life-changing check. But the 45 days between the LOI and closing were, by the owner's account, the most stressful six weeks of a 22-year career.

That's due diligence. And understanding what it is, how it works, and how to prepare for it is the difference between surviving the process and getting buried by it.

## What Due Diligence Actually Is

Due diligence is the buyer's investigation period — typically 30 to 60 days after a Letter of Intent (LOI) is signed — during which the buyer and their advisory team examine every aspect of the business to confirm that what was represented in the marketing materials and negotiations is accurate.

Think of it as the inspection period in a real estate deal, except far more comprehensive. The buyer isn't just checking for leaks and termites. They're auditing financial statements, verifying customer relationships, reviewing legal obligations, examining equipment condition, assessing employee arrangements, and stress-testing every assumption that drove the offer price.

Due diligence serves two purposes. First, it confirms (or challenges) the business's value. Second, it uncovers risks that need to be addressed — either through price adjustments, deal structure modifications, or representations and warranties in the purchase agreement.

## What the Buyer's Team Is Looking For

The due diligence process typically covers six major areas. Knowing what's coming allows sellers to prepare — and preparation is the single best predictor of a smooth due diligence experience.

**Financial Verification.** Three to five years of tax returns, profit-and-loss statements, balance sheets, and bank statements. The buyer's CPA will compare reported income to tax returns to bank deposits. They're looking for consistency. Revenue that appears on the P&L should match what flowed through the bank. Expenses should be categorized correctly. Add-backs should be documentable and defensible. Any inconsistency — even an innocent one — triggers questions, delays, and potential price renegotiation.

**Customer and Revenue Analysis.** Who are the customers? How concentrated is revenue? If one customer represents 30%+ of revenue, that's a risk the buyer will price in. What's the trend? Is revenue growing, flat, or declining? For subscription-based businesses — car washes, self-storage — what are the retention rates? For project-based businesses — HVAC, construction — what's the pipeline? The buyer wants to understand not just the numbers but the durability of those numbers.

**Legal and Regulatory Review.** Leases, contracts, permits, licenses, pending or threatened litigation, intellectual property, insurance coverage, environmental compliance. Every legal obligation the business carries will be examined. The buyer's M&A attorney is specifically looking for liabilities that could transfer with the sale — pending lawsuits, regulatory issues, lease restrictions on assignment, or contracts with change-of-control provisions.

**Operational Assessment.** Equipment condition and maintenance records. Technology systems. Inventory (if applicable). Physical inspection of the facility. The buyer wants to know: does this business operate the way it was presented? Are there deferred maintenance issues that will require capital investment post-closing? Is the equipment at end-of-life, or does it have years of service remaining?

**Employee and HR Review.** Employee roster, compensation structure, benefits, employment agreements, non-compete arrangements, pending HR issues. For an HVAC company, the licensed technicians are essential to the operation — the buyer needs to understand retention risk and compensation expectations. For a dental practice, the hygienists and front-office staff are the backbone of patient experience. Employee continuity is often as important as customer continuity.

**Tax Compliance.** Payroll tax filings, sales tax compliance, property tax status. The buyer doesn't want to inherit tax liabilities. An outstanding sales tax obligation or a payroll tax discrepancy can become the buyer's problem if not identified and resolved before closing.

## The Common Due Diligence Killers

Most Austin business deals that die during due diligence don't die because of fraud or catastrophic problems. They die because of preventable issues that the seller could have addressed before going to market.

**Inconsistent financials.** The tax return says $1.2 million in revenue. The P&L says $1.35 million. The bank deposits total $1.28 million. Three different numbers for the same thing. Maybe the differences are explainable — cash vs. accrual timing, deposits in transit, revenue recognition differences. But every inconsistency requires an explanation, and enough unexplained inconsistencies erode the buyer's confidence.

**Undisclosed liabilities.** A pending lawsuit the seller "forgot" to mention. A workers' comp claim that's still open. An equipment lease with 36 months remaining that wasn't disclosed. These surprises don't just threaten the deal — they destroy the trust that makes a deal possible. Buyers expect to find issues. They don't expect to find hidden ones.

**Customer concentration.** If 40% of revenue comes from one customer and the buyer discovers it during due diligence rather than during marketing, the buyer wonders what else wasn't disclosed. Customer concentration is a real risk that affects valuation — but it's manageable when disclosed upfront and addressed structurally (through earnouts, customer introductions, or long-term contracts).

**Lease issues.** The lease expires in 18 months and the landlord won't commit to renewal terms. Or the lease has a clause restricting assignment without the landlord's consent — and the landlord wants a 20% rent increase as a condition. Lease problems kill more small business deals in Austin than almost any other single factor.

## How to Prepare (Starting Now)

The best time to prepare for due diligence is 12–24 months before the sale. The second-best time is right now.

**Organize three to five years of clean financial records.** Tax returns, P&Ls, balance sheets, bank statements — all reconciled and consistent. If there are discrepancies, identify and explain them before a buyer has to ask.

**Create a due diligence data room.** A secure digital folder containing all the documents a buyer will request — organized by category (financial, legal, operational, HR). Having this ready before due diligence starts signals professionalism and accelerates the process.

**Resolve known issues.** That pending dispute with a former employee? Settle it. The equipment lease that's in default? Cure it. The insurance policy that lapsed? Reinstate it. Every unresolved issue that surfaces during due diligence becomes leverage for the buyer to renegotiate.

**Brief your CPA and attorney.** They'll be fielding questions from the buyer's team. Make sure they understand what's coming, have access to the relevant documents, and are prepared to respond promptly. Slow responses during due diligence signal disorganization — or worse, evasion.

**Prepare for the emotional toll.** Due diligence feels personal. The buyer's team is questioning everything — not because they don't trust the seller, but because it's their job. Sellers who take every question as an accusation burn out quickly. The right mindset is: every question answered is one step closer to closing.

The [IBBA's Buyer & Seller Q&A Center](https://www.ibba.org/resource-center/qa/) addresses dozens of the most common due diligence questions — from how long it typically takes to what happens when a buyer finds something unexpected. It's written by practicing intermediaries, not academics, and it mirrors the exact conversations that happen in real transactions.

## The Seller's Broker's Role During Due Diligence: Your Shield and Your Quarterback

Most sellers don't realize that the broker's job fundamentally changes once due diligence begins. Pre-LOI, the broker is a salesman — marketing the business, vetting buyers, negotiating the headline terms.

Post-LOI, during due diligence, the broker becomes the seller's quarterback, shield, and translator. This distinction is critical, and it's where the difference between a transactional broker and a true advisor becomes visible.

**Managing Direct Pressure from the Buyer Team**

The buyer's team — their CPA, their M&A attorney, their operations person — will have intense, detailed questions. And they'll often ask to pose those questions directly to the seller.

This is where your broker intervenes. A good seller's broker doesn't prevent direct conversation (transparency serves everyone), but they manage the *structure* and *rhythm* of it. Instead of allowing ad hoc calls from the buyer's accountant whenever a question surfaces, the broker schedules consolidated due diligence calls — weekly or biweekly — where all parties are present.

Why does this matter? Because without structure, seller nervousness compounds. The buyer's CPA calls with a question about a specific expense category. The seller, stressed, provides an answer that sounds defensive. The buyer's team interprets the tone as evasive rather than clarifying. The thread of doubt enters the buyer's mind. Deal risk increases.

A seasoned broker manages the pacing and tone. "Your CPA's question about the vehicle expenses is standard — we've had this come up in twelve transactions. Here's the documentation. Here's how we'll address it." The buyer's team hears confidence and clarity rather than defensiveness.

**Translating Between Worlds**

The buyer's team speaks in M&A language. The seller speaks in operating-the-business language. The broker translates.

The buyer's attorney is asking about "representations and warranties." The seller hears "legal liability risk." The broker explains: "They're documenting what you've told them about the business. You're confirming it's accurate. Standard transaction documentation — protects you both."

The buyer's CPA is challenging an add-back — a personal health insurance premium the seller had been running through the business. The seller hears accusation. The broker explains: "Insurance isn't a recurring business expense. If a buyer is asking if they can also claim it as an add-back, they're testing our position. We need to be clear: that was a legitimate add-back for you. They'll hire their own insurance. Different outcome for them. That's why it's documented and adjusted."

This translation work prevents misunderstandings from metastasizing into deal-threatening conflicts.

**Controlling Document Flow and Preventing Over-Disclosure**

The buyer will request documents. Often, a lot of documents. A good seller's broker manages this process so that:

1. **Requests are specific and justified.** A buyer's request for "all communications related to operations" is too broad. A broker channels it into "operational manuals, service schedules, quality assurance documentation." Specific requests. Reasonable scope.
2. **Confidential information stays protected.** The business's supplier list, pricing, vendor contracts, customer data — this is sensitive. A broker negotiates confidentiality and data room access restrictions so the buyer gets what they need without unreasonable access to competitive information.
3. **Timing doesn't allow drift.** A buyer requests documents. The broker ensures they're provided within 48 hours. Slow responses kill momentum and signal disorganization. Fast, organized responses signal professional operations.
4. **Redundant requests get consolidated.** The buyer's CPA asks for tax returns. Then the buyer's attorney asks for tax returns. Then the buyer's operations person asks for tax returns. Instead of three separate deliveries, the broker packages once and references it. Efficiency matters psychologically — the buyer perceives the seller as organized and responsive.

**Keeping the Deal on Track (Knowing When to Push Back)**

Sometimes the buyer's team requests something unreasonable — overly intrusive, outside scope, or designed to create leverage. A good broker knows when to accommodate and when to push back.

Example: The buyer wants to interview all customer accounts representing more than 5% of revenue. That's reasonable. A buyer wants access to your personal email accounts to verify business communication. That's not reasonable, and a broker stops it.

Example: The buyer wants three years of detailed inventory records. Reasonable if inventory is material. The buyer wants six years of casual employee timekeeping records for the business — that's not relevant to a sale and opens privacy exposure. The broker negotiates it down.

Example: The buyer wants verification that all insurance claims from the past five years have been disclosed. Reasonable — this prevents surprises about liability risk. The buyer wants the seller to indemnify them against any claim that could possibly be made about any incident from the past decade. That's unreasonable scope, and the broker negotiates realistic windows and dollar caps.

This is high-stakes judgment work. A bad broker either rubber-stamps every buyer request (leaving the seller exposed) or fights every request (killing deal momentum). A good broker knows the difference between reasonable due diligence and overreach — and handles both accordingly.

**Coaching the Seller Through the Emotional Component**

Due diligence is psychologically harder than most sellers anticipate. For three to eight weeks, your business is being examined microscopically. Questions that feel accusatory are actually procedural. Requests that feel like invasions are standard. Adjustments to the offer price feel like betrayal, even when they're normal.

A broker who has done this fifty times understands the psychology. They coach the seller: "Day 18 is always when sellers panic. It's normal. By day 35, the pattern is clear and momentum returns. We're on schedule." This context prevents panic-driven decisions that damage deals.

The broker also prevents the seller from communicating directly with the buyer in moments of frustration. An unhappy email sent at 10 PM on a stressful day can poison a deal. The broker is the buffer that prevents that. "Let's talk tomorrow morning. You're reacting to a procedural question, not a deal-threatening issue."

**Post-Due Diligence Adjustment Negotiation**

Nearly every deal adjusts during due diligence. The question is whether that adjustment is 2% or 12%. A good broker has negotiated the initial LOI with built-in margin for likely adjustments. They've been clear with the seller about probable working capital adjustments, likely operational questions, and probable add-back challenges.

When adjustments surface, the broker frames them professionally: "We anticipated something like this. Here's why this is within normal range. Here's why this is outside bounds. Here's where we hold the line, and here's where we flex." That strategic approach typically results in smaller adjustments than brokers who've positioned deals without understanding likely friction points.

The broker who does this work well is often not the most visible part of the transaction. The seller may never consciously notice the quiet work that's preventing fires from spreading. But that's exactly right — a broker's job during due diligence is to keep things moving smoothly while protecting the seller's interests.

## The Closing Adjustment

Most Austin business deals don't close at the exact LOI price. Due diligence findings typically result in a 3%–7% adjustment — sometimes higher. This isn't failure. It's the process working as designed.

The adjustment might come from working capital being below the agreed target. From equipment that needs replacement sooner than represented. From revenue trending below projections during the due diligence period. From an add-back that the buyer's CPA challenges.

Sellers who expect a small adjustment handle it gracefully. Sellers who believe the LOI price is sacred fight over every dollar — and risk killing the deal over adjustments that are well within normal range.

The goal of due diligence isn't perfection. It's confirmation. The buyer is confirming that the business is substantially what was represented. If it is — with minor adjustments — the deal closes. If it isn't — if the financials were inflated, the risks were hidden, or the operation was misrepresented — the deal dies. And it should.

The sellers who survive due diligence with their deal intact are the ones who had nothing to hide — and the documentation to prove it.
