What Would Warren Buffett Say About Your Business?

His published reasoning reduces to a handful of questions he applies to almost everything. You can run your own business through them.

Buffett has written publicly for over sixty years, mostly in annual letters to Berkshire Hathaway shareholders. Read enough of them and the reasoning is strikingly repetitive, which is the point. A small set of questions, applied relentlessly.

These are the ones that transfer to an operating business rather than to stock selection.

1. What stops someone from doing this cheaper?

His term is the moat. The underlying question is unsentimental: if a well funded competitor decided to take your customers tomorrow, what actually stops them? Acceptable answers include switching costs, brand that permits higher pricing, scale advantages, and network effects. Working harder is not an answer. Caring more is not an answer.

Most owners, asked this directly, describe their service quality. Buffett's writing treats that as the absence of a moat rather than one, since it depends entirely on continued effort.

2. Can you raise prices without losing customers?

He has called this the single most important measure of a business. Pricing power is the observable evidence that a moat exists. Everything else is a story about a moat.

It is also a test you can run this month rather than theorise about. See should I raise my prices.

3. Would you be comfortable owning this for ten years without selling?

Not a question about intention to sell. A test of whether you believe the business is durable. Owners often discover that they are managing something they quietly expect to decline, which is a strategic position worth making explicit rather than leaving unexamined.

4. How much cash must you put in to grow?

A recurring theme in his letters is that growth is only valuable when it does not consume all the cash it produces. Businesses that must fund inventory, equipment, or working capital ahead of every increase in revenue can grow steadily and enrich nobody. Growth is not automatically good, which is a genuinely uncomfortable idea for most founders.

5. Is this inside what you actually understand?

His circle of competence idea is usually cited as modesty. It is closer to risk management. The claim is not that you should stay small, it is that you should know precisely where the boundary of your understanding sits, because that is where losses come from.

6. What would have to be true for this to fail completely?

He inverts constantly, a habit he credits to Charlie Munger. Rather than asking how to succeed, ask what would guarantee failure, then avoid those things. It is a more tractable question, since the routes to failure are fewer and more visible than the routes to success.

The obvious caveat

Buffett is an investor evaluating businesses from the outside, not an operator building one. Some of this transfers imperfectly. A young company deliberately spending ahead of revenue to capture a market is doing something his framework treats sceptically and which is sometimes exactly right.

The value is not in adopting the framework wholesale. It is that these questions are uncomfortable in a specific direction, toward durability and away from momentum, and most owners lean the other way. Running your business through a framework that disagrees with your instincts is the point.
