Avoiding Undervaluation: How Brokers Help Navigate Risky Signals

Weighing a national for-sale site against Columbus business brokers? See what each does well, what happens after the first inquiry, and how to choose.

Many due diligence failures trace back to records a seller could have organized months earlier. Reconcile your financials, document every add-back, confirm your lease and contracts can transfer, and clean up your Ohio sales tax filings before you list. A broker who screens buyers and manages the document flow keeps small problems from turning into deal-ending ones. A business sale falls apart in due diligence when what the buyer verifies doesn't match what the seller presented. The usual gaps are earnings that won't reconcile to tax returns, add-backs with no records, contracts that can't transfer, and unpaid tax exposure. Columbus sellers avoid this by assembling and checking those records before the business is listed. Quick Answer: Due diligence punishes surprises. Find yours and fix them before a buyer does, while the timeline is still yours. KEY TAKEAWAYS Due diligence is the buyer's verification period after a letter of intent, and the purchase price depends on what it confirms. Deals break when financials, contracts, or tax records don't match what the buyer was shown. Under Ohio law, a buyer who doesn't hold back money for a seller's unpaid sales tax can become personally liable for it, which makes tax clearance a closing issue. Recent industry data shows most sellers start the process with less than a year of exit planning. The records you organize six to 12 months before listing do more to protect your price than anything you scramble to find once a buyer starts asking. WHERE DEALS ACTUALLY BREAK For a lot of owners, the hardest part of selling a business comes after they've accepted an offer. The letter of intent is signed, the price is agreed, and you've started picturing what comes next. Then the document requests arrive. This is due diligence, and it's where a sale gets tested line by line. If you plan to sell your business in Columbus, Ohio, or anywhere in Central Ohio, knowing what buyers look for protects the price you negotiated. At First Choice Business Brokers Columbus , we prepare sellers for this phase long before a buyer is at the table. Here's what buyers verify, where deals tend to come apart, and what you can do about it now. What Actually Happens in Due Diligence When You Sell a Business? Due diligence is the period after a letter of intent when the buyer, their lender, and their advisors verify what the seller has represented. They review tax returns, bank statements, leases, contracts, payroll, licenses, and liabilities. The purchase price is conditional on what they find, so this phase decides whether the deal actually closes. For most Main Street businesses, the request list is long but predictable. Expect to provide three to five years of federal tax returns and profit-and-loss statements, recent bank statements, an equipment and inventory list, your lease and major contracts, and employee details. If the buyer is financing with an SBA-backed loan, the lender runs its own review alongside the buyer's, with its own list of questions. Timing matters too. The IBBA and M&A Source Market Pulse Survey for Q2 2026 found that Main Street deals took six to 10 months from engagement to close, and that timelines lengthened compared with the prior quarter. Due diligence is one of the longest stretches in that window, and every week it runs long gives a buyer more time to second-guess . Why Do Business Sales Fall Apart in Due Diligence? Sales fall apart in due diligence when the verified business doesn't match the business the buyer agreed to buy. The most common gaps are earnings that won't reconcile to tax returns, owner add-backs with no paper trail, revenue concentrated in a few customers, and leases or contracts that can't pass to a new owner. The Numbers Don't Reconcile A buyer's accountant will line up your profit-and-loss statements against your tax returns and bank deposits. When those three sources tell different stories, the buyer stops trusting all of them. Cash revenue that never made it onto a return is the classic example. You can't ask a buyer to pay for income you told the IRS you didn't earn. Add-Backs Without Receipts Seller's discretionary earnings, the figure most small businesses are priced on, includes add-backs such as the owner's salary, a personal vehicle, or a one-time repair. Each add-back raises the value, and each one has to be proven. An add-back you can't document is one a buyer will subtract , and the price moves with it. This is also where advisors genuinely disagree. Some push every seller to commission a sell-side quality of earnings review before listing. On a $3 million company, that conversation is worth having. On a $500,000 service business, the cost can outweigh the benefit, and clean books with a well-supported add-back schedule may do the same job. We look at that one deal by deal. Customer Concentration and the Owner Problem If one customer accounts for a large share of revenue, or every important relationship runs through you personally, the buyer is asking a fair question: what happens when you leave? When this surfaces late, buyers commonly respond by moving part of the price into an earnout or a longer seller note. Some sellers accept that. Others walk away from the restructured offer, and months of work go with them. Leases, Licenses, and Contracts That Won't Transfer A restaurant with four years left on a favorable lease is worth more than the same restaurant on a month-to-month arrangement. If that lease requires landlord consent to assign and nobody has asked the landlord, the buyer's lender may not fund. The same applies to franchise agreements, major supplier contracts, and permits, such as liquor permits, that don't simply pass to a new owner. If you want to see this review from the other side of the table, our guide to the red flags buyers miss without a broker walks through what a careful buyer checks. The Ohio Tax Rule That Can Hold Up a Closing Ohio law requires a buyer to withhold enough of the purchase price to cover a seller's unpaid sales tax until the seller produces a receipt or certificate from the Ohio tax commissioner. A buyer who skips that step becomes personally liable for the tax, so experienced buyers, attorneys, and lenders insist on it. The rule is in Ohio Revised Code Section 5739.14 . It also requires the seller to file a final sales tax return within 15 days of selling or quitting the business.  For a retailer, restaurant, or any business that collects sales tax, a sloppy filing history doesn't stay in the past. It shows up as money held back at closing, or as a delay while the certificate gets sorted out. Pull your Ohio sales tax filing history before you list. Your CPA can usually tell you quickly whether anything is outstanding, which beats finding out when a closing date slips. How Do Columbus Sellers Prepare Before a Buyer Asks? Columbus sellers prepare by building the buyer's due diligence file themselves, ideally six to 12 months before listing. That means reconciled financials, a documented add-back schedule, reviewed leases and contracts, clean tax filings, and a plan to reduce dependence on the owner. A broker organizes the file and releases it only to qualified buyers under an NDA. Most owners start well after that point. In the same Q2 2026 Market Pulse survey, between 60% and 90% of sellers across market segments had done less than a year of exit planning, or none at all, and retirement was the leading reason owners went to market. Here's what to gather, and why a buyer will ask for it:
