Buying a Business: Know What You Are Inheriting First

If you are buying a business right now, there is a good chance AI is part of your plan. You see a profitable company, you see how much of its work software could take on, and the deal starts to look even better. That is a fair way to look at it. It also skips the question that decides whether the deal works: what are you actually inheriting?

When you are buying a business, you are not only buying trucks, a lease, and a customer list. You are taking over someone else's succession plan, whether the seller ever called it that or not. Whatever that plan leaves out becomes your problem on the first day you own the place, and AI will not fill the gap for you.

What the Spreadsheet Does Not Tell You

Most advice on buying a business starts with the numbers: revenue, margins, equipment, and the asking price. Those numbers matter, and they are the easy part, because the seller can hand them to you on paper. The harder part is what happens inside the business when the owner is not there. Who holds the customer relationships. What only the owner knows how to do. Whether anything is written down, or whether it all lives in one person's head.

AI comes into the picture later than most buyers expect. Every business can benefit from it in some way. The open question is how much work stands between the business you are buying and one where AI can help, and who will do that work, you or the seller. Your house must be in order before AI is fully effective. If nobody ever documented how the business runs, adding AI on day one only automates the guessing.

Knowing the Work Is Not Knowing the Business

I watched a painting company change hands. The new owner was not a stranger. He had worked there as an employee before he bought it, and the company had 10 employees at the time. He got the equipment and the trucks. What he did not get was a good handoff. He did not have enough information to run the business itself, he had some clients and lost some of them, and the financial structure was not there. All of this happened before AI was part of the picture.

Over time the jobs kept getting smaller. He kept going after the big jobs, the ones that pay well, and then he waited to be paid. While he waited, he did not have the money to pay his people. With too little work coming in and no cash to cover payroll, he had to let employees go, one after another, until a business that started with 10 people was down to one.

He knew how to paint. Knowing the work and knowing the business are two different kinds of knowledge, and a buyer needs both. Software can speed up quoting, scheduling, and follow-up, but it cannot replace a financial structure that was never set up, and it cannot bring back customers who already left.

When the Person Running It Does Not Know It

The second business was a family engraving company. It made business cards, custom stationery, and printing for signs, and it had been around for years. It belonged to the wife's family, and when it passed to her, her husband took over running it. He was not familiar with the business.

This was a long time ago, and I watched it happen over the years. I learned the details of how it all went down later. He was not getting new customers, and he was not holding on to the ones the business already had. He was not keeping employees either. He was busy with other things and not really managing the company. It was never one dramatic mistake. The business withered slowly, and it took somewhere around eight to 10 years before nothing was left. Nobody stepped in.

AI could not have saved that business. It cannot give someone knowledge of a trade they never learned, and it cannot manage customers and employees for a person who is not paying attention to them. If you do not know a business well enough to run it, you should not be buying it, and the same holds when it is handed to you.

Do You Want the Business?

There is a third question that has nothing to do with documents or systems. Do you want this business? I have seen businesses wither after a child took them over with no interest in them, and after owners simply stopped caring. It happens all the time.

A business can make good money and look right on paper, and still be the wrong one for you. Some buyers are drawn in because it looks like a good deal, or because it looks like fun, or because the numbers work. Measure it against what you value and what interests you, because you will be running it for years. AI will not supply interest you do not have. It can be fun to put AI on top of a business if that excites you, but AI has no interest in the business at all. You do, or you should.

What to Ask the Seller Before You Buy

Start with a list of questions for the current owner. These are not the only ones, but they show you what you are inheriting.

1. What is documented. Ask directly what is written down and what only the owner knows. If the honest answer is "I just know how to do it," that is not a small gap. That is the business. No documentation at all should raise a flag.

2. Where the files live. Ask where files are saved and how they are organized. Files scattered across one inbox, one laptop, and a filing cabinet in the back room suggest that very little else is documented either.

3. Which systems the business runs on. List the software it uses day to day: accounting, scheduling, customer records, whatever applies. Once you know the systems, you can look at what AI is already built into them, which may cost nothing extra, before you buy anything new.

4. Who the customers are. Ask how long customers have stayed and how often the business reaches out to them. A customer base that has been loyal for years is a different asset than one that turns over every few months. Ask who does the follow-up.

5. How the business looks to a machine. Ask whether the website is set up properly, whether AI systems can read it, and whether the business sells products online. A site that nobody can find, or that machines cannot read, is a gap you will inherit with everything else.

6. Who works there. Ask how many employees there are, how long each has been there, and what happens if two or three of them leave after the sale closes.

None of this replaces the financial due diligence a buyer already knows to do. It sits beside it, because what the business is built on decides whether you can run it.

What to Do With the Answers

The answers do not decide whether to buy. They decide what the business will cost you beyond the price. If most of the business lives in the owner's head, you have two choices. You can ask the seller to document it before the sale closes, or you can get a commitment that the seller will make time to be interviewed afterward, so you can capture the decisions the owner makes without thinking about them. Either one is work, and you should know which one you are signing up for and who will do it.

If the foundation is in order, AI can come sooner, and your first year goes to learning the business instead of rebuilding it. Count that time when you decide what to pay. A business with no documentation is not a bad deal by itself, but it is a different deal than the spreadsheet shows.

The Seller's Side of the Same List

This list works in the other direction too. If you are the one selling, the gaps that worry a buyer are gaps you can close before you ever list the business. A business with documented processes, files in order, and a clear picture of its systems can bring a higher price than the same business with all of that locked in one head. If you cannot finish the documenting, make yourself available to be interviewed, so the buyer can capture how you make decisions.

That is the same work Foundation First asks of every owner, buying or selling. You need to know where you are on the map before you know which direction leads to your destination.

Know What You Are Inheriting

A large number of businesses are about to change hands. McKinsey projects that roughly six million small and medium-size businesses will face ownership transitions by 2035, representing up to $5 trillion in enterprise value, with more than one million of them viable for sale. McKinsey also reports that more than half of small business owners are now over 55.

Some buyers are already betting on this. Thrive Holdings has raised more than $2 billion to buy accounting and IT services firms and rebuild how the work gets done inside them. It reports cutting tax preparation time by more than 30% across more than 7,000 returns, though those figures come from Thrive itself, are unaudited, and have no published baseline. Whatever the number turns out to be in any single deal, the point holds for every buyer, large or small. You cannot know what AI can do for a business until you know what the business is built on.

The spreadsheet tells you what the business made, and only a closer look tells you what you are inheriting.
