Key Mistakes that Could Impact Your Sale

By Michael D. Rubin, CEO & Founder · Updated September 2026 · 739 words

Four mistakes quietly lower what a buyer will pay: records that do not hold up, a business that has fallen behind on technology, a workforce that keeps turning over, and investment put off because the owner plans to sell. Each one is far easier to fix two years before a sale than two weeks into due diligence.

The simplest protection is to run the company as if a buyer could look at it at any time. That habit forces regular, honest checks of what is working and what is not. It keeps the company improving, and it keeps it ready if an unexpected offer or life event arrives.

Mistake 1: Records a buyer cannot rely on

Buyers value a company on its earnings, so they test the numbers hard. Expect them to ask for three years of financial statements and tax returns, monthly results for the current year, and the detail behind revenue, margins and major costs. Trouble starts when statements, tax returns and bank deposits do not reconcile, when personal expenses are mixed into the business without clear records, or when revenue by customer cannot be produced on request.

Buyers do not pay for earnings they cannot verify. They either discount them or move part of the price into an earnout, a payment that depends on future results. See which financial statements a valuation needs for the full list.

Close the books every month on a set schedule, and have your CPA reconcile the statements to the tax returns each year.

Mistake 2: Falling behind

A company still running on paper job tickets, an outdated website and scattered spreadsheets tells a buyer it will need investment after closing, and the buyer will subtract that cost from the price. Buyers look for systems that work: scheduling and dispatch, inventory, customer records, accounting and a web presence that brings in business.

You do not need the newest tools, but you do need current ones that staff actually use. A company that is easy to find online, with accurate information and recent customer reviews, also looks like one that is still competing for work rather than coasting on old relationships.

Mistake 3: A workforce that will not stay

Buyers want stability. High turnover suggests hidden problems with pay, management or culture, and it raises the question of whether the team will still be there after the owner leaves. Know your turnover and the tenure of your key people, and deal with the causes.

Written job roles, trained second-in-command positions and fair pay for the market all cost less than the discount a buyer applies to an unstable team. So does a clear answer to the question every buyer asks about key employees: what keeps them here, and what would make them leave?

Mistake 4: Putting off investment

Some owners stop spending once they decide to sell, reasoning that the next owner can pay for new trucks or equipment. Buyers see through it. Worn equipment and deferred maintenance show up in site visits and in the history of capital spending, and buyers deduct the catch-up cost, often generously.

Keep up normal maintenance and replacement, and continue the investments that support growth, such as a new service line, a sales hire or a system upgrade. A company that is still investing looks like one with a future, and a buyer pays for the future, not the past.

Why these mistakes compound

Each mistake on its own might cost a buyer's confidence on one point. Together, they change how the buyer reads everything else. A buyer who finds messy records starts to doubt the customer data; one who sees worn equipment wonders what else was deferred. The result is more questions, a longer due diligence, a lower offer, or more of the price pushed into terms that depend on the future.

The reverse is also true. A company that is clean on all four points gives buyers the confidence to compete on price and to offer cleaner terms, such as more cash at closing.

How we help owners avoid these mistakes

MDR & Associates' pre-exit consulting covers the 12 to 24 months before a sale, when these problems can still be fixed on your schedule rather than a buyer's. A formal business valuation shows which issues are costing you the most, and the twelve-month plan to prepare your business for sale sets out the order of the work.

Questions owners ask next

Do I need audited financial statements to sell?

Usually not for companies in the lower middle market. Reviewed or well-prepared compiled statements that reconcile to tax returns and bank records are often enough, though some buyers or lenders ask for more. A quality of earnings review, arranged by the buyer or the seller, is common in larger deals.

Should I stop running personal expenses through the business before selling?

It helps. Buyers accept documented owner expenses as add-backs, but every add-back needs proof, and too many invite doubt about the rest of the numbers. Cleaning them up a year or two before a sale makes earnings easier to verify. Your CPA should advise on the tax side.
