Selling a business is one of the biggest financial decisions an owner will ever make, yet most entrepreneurs only go through the process once in their lives. That means the learning curve is steep, the stakes are high, and costly missteps are easy to make. The goal of this article is to help owners understand the most common mistakes when selling a business and how to avoid them before they undermine value.
The High Cost of Getting It Wrong
Before diving into the specifics, it’s worth emphasizing why mistakes matter so much. When owners miscalculate during a sale, the consequences are not small, they can reduce valuation, scare away serious buyers, drag out the process, or even cause the deal to fall apart entirely.
Even worse, most of these errors happen early in the process, often before the owner even speaks with a serious buyer. That’s why learning the common mistakes when selling a business is just as important as preparing financials or identifying the right buyer pool.
Mistake #1: Mispricing the Business
One of the most widespread errors sellers make is mispricing their business from the outset. This usually goes in one of two directions: pricing too high or pricing too low.
Owners frequently overvalue their company due to emotional attachment or because they assume a competitor will pay a large premium. On the other side of the spectrum, underpricing often happens when a seller receives a single unsolicited offer and assumes it must reflect “market value”, when in reality, it represents one buyer’s opinion, not a competitive benchmark.
The right valuation is never a guess and never a multiplier plucked from a vague industry rule of thumb. It’s a function of the company’s actual earnings quality, growth potential, customer stability, management depth, and industry trends, along with the usual financial valuation models and comparable sales methodologies. Without understanding these factors, and how buyers interpret them, mispricing becomes inevitable.
And unlike selling a house, businesses don’t benefit from “testing the market” with a wrong price. With a business sale, poor positioning early on can permanently damage perceived value.
Mistake #2: Talking to Only One or Two Buyers
Another of the most common mistakes when selling a business is limiting the buyer pool. When owners talk to just one or two interested parties, they give up negotiation leverage before the process even begins.
A fair price is not discovered through a single conversation, it emerges from competition. Buyers naturally want to pay the lowest acceptable price. When they know they are the only party at the table, they take advantage of that power dynamic, often pushing for concessions, deferred compensation, or lower upfront payments.
Most unsolicited inbound offers (especially from private equity or search fund buyers) are designed to test a seller’s sophistication. If the seller bites early, the buyer captures all the upside. If the seller creates competitive tension, multiple qualified buyers bidding at the same time, the dynamic reverses, and value typically rises.
Running a competitive process is not just about price, it increases deal certainty, improves structure, and limits the buyer’s opportunity to stall or renegotiate late in diligence.
Mistake #3: Poor Confidentiality Management
Confidentiality is one of the most overlooked landmines for owners selling independently. If news of a sale leaks prematurely, employees may panic, competitors may target your customers, and vendors may renegotiate terms out of fear of instability.
Some sellers overcorrect and become overly guarded, withholding too much information even from legitimate buyers. This leads to another risk: buyers assume the worst when they feel they’re being kept in the dark.
The right approach is controlled disclosure, enough information for the buyer to gain confidence and price appropriately, but not so much that internal operations are disrupted. This balance is extremely difficult to strike without professional guidance and is one of the most common mistakes when selling a business privately.
Mistake #4: Weak Preparation Before Going to Market
A business that is not properly prepared for sale will almost always struggle during diligence — even if the buyer pool is strong. Preparation goes far beyond organizing tax returns or printing financial statements. Buyers want to understand earnings quality, customer concentration risks, management continuity, and systems reliability.
Many sellers underestimate just how much narrative and data must be prepared in advance, which leads to surprises in diligence, and surprises erode trust and value. According to the U.S. Chamber of Commerce, a major reason deals fail is lack of preparation before a sale, including missing documentation and unclear operating procedures.
Proper preparation also helps filter out unserious buyers early, allowing stronger offers from qualified acquirers to rise to the surface more quickly.
Mistake #5: Ignoring Deal Structure (Not Just Price)
Many first-time sellers focus exclusively on the headline purchase price and overlook how easily structure can erode that number. The real question is: How much do you actually receive at closing? A deal with a high purchase price but a large earnout, a seller note, or aggressive working capital requirements may end up delivering far less than expected.
This is where experienced buyers have the upper hand. They know how to negotiate not only price, but also timing of payments, financing mix, reps and warranties, indemnifications, working capital adjustments, and post-closing obligations. Without an M&A advisor, sellers often agree to conditions that shift risk back onto them, unknowingly giving away millions of dollars in actual value.
Mistake #6: Relying on the Wrong Advisors
Another trap is assuming your long-time CPA or general business attorney is prepared to handle a complex M&A sale process. Most have handled partner disputes, restructurings, or routine transactions, not competitive buyer processes, debt-funded acquisitions, or private capital negotiations.
This results in deals stalling or dying, not because the business lacked value, but because the advisory team wasn’t familiar with M&A-specific structuring, financing, or diligence. Inexperienced advisors also underestimate the sophistication of buyers, especially private equity groups and institutional buyers, who manage transactions like this every day.
Choosing the wrong team can mean higher taxes, bad terms, delayed closings, or worse, no closing (and no money), at all.
Mistake #7: Trying to Do It Yourself
Perhaps the biggest of the common mistakes when selling a business is assuming a DIY approach saves money. In reality, it typically costs multiples more than a broker’s fee. Owners running their own process:
- Don’t get access to the full buyer pool
- Lose confidentiality control
- Lack leverage in negotiations
- Misjudge deal structure and bankability
- Take buyer claims at face value (especially around “fair” price)
And while a buyer may insist, “We don’t need a competitive process , we’ll give you a fair offer,” what they really mean is, “We don’t want to compete.”
Few sellers regret hiring professional representation. Many regret not doing so sooner.
