This week, I had a conversation with an entrepreneur who’s considering closing his business. The business breaks even or runs at a slight loss most months. When someone is considering closing a business, I wonder why, so I asked.

This entrepreneur has had his business for about a decade. He’s no longer excited by it and hates the thought of going back to being involved in its day-to-day operations. He’d rather spend his time on new entrepreneurial pursuits, which he’s already doing. This makes sense to me. Around the decade mark with my company, I began to lose enthusiasm and remove myself from certain aspects of the operations. I’ve heard other entrepreneurs share similar experiences.

Next, I wanted to understand the issue with the business. Why wasn’t it generating a profit? Operationally, it’s running smoothly with a small team. The work gets done as expected and customers are happy. But they’re not getting enough customers through the door to generate the revenue needed to turn a profit. I asked how they acquire customers and let customers know they exist. It turned out that the entrepreneur hasn’t done any marketing in a few years. He did big marketing pushes years ago, which were successful, and he’s been coasting on word of mouth ever since. But word of mouth is dwindling, and the result is fewer customers.

Marketing is just like other business functions, with one important difference. When you stop operations, you notice immediately because the work isn’t getting done and customers are mad. When you stop marketing, you often don’t see the impact right away. Awareness of your business gradually declines. Revenue gradually declines. One day, you realize you don’t have enough business.

I told this entrepreneur that it seems like he’s got a marketing issue. If he can dedicate himself to a few months of restarting his marketing function and incorporating metrics that quantify his return on marketing spend, he’ll likely see a profit again in a few months. Instead of closing the business, he’ll have a good shot at getting marketing running smoothly without him—just like the rest of the business—and then selling the business. Instead of getting nothing and walking away, he may be able to sell it, get a nice chunk of change, and pursue his new entrepreneurial ideas with a clear mind and capital to fund them.
