The Top Line Is The Business

Every business does three things: builds things, sells things, and supports things. That's it. But here's what I've noticed in my own search and in conversations with other buyers: we spend most of our diligence energy on the build and support functions. Systems, processes, team structure, financing, distribution channels, cost controls. All important. All downstream of one thing. If you can't sell your thing, the other two don't matter. Most buyers, regardless of background, evaluate businesses through an operational lens. The top line gets less scrutiny than it deserves. And I'd argue that's where the real risk lives. When I look at a target, I'm asking: is the revenue engine transferable to a new owner, or is it founder-dependent in ways the CIM doesn't reveal? Is growth real, or is it propped up by discounting, one large customer, or a spike in one-time services? Does the business know why it wins deals, and can it repeat that? Here's the uncomfortable truth: most operational problems are solvable. Bad systems, thin processes, underbuilt teams – these all have playbooks. Top-line problems are harder, often deeper, and frequently disregarded in diligence precisely because they're less comfortable to confront and harder to control. You can install EOS. You can't install customers. What's your top-line litmus test before you go deeper on a deal?

Hit the nail on the head with “is the revenue engine transferable to the new owner.” Basically, is the top line sustainable or is there a real possibility of that disappearing overnight? I’ve seen many businesses where that’s the case. An easy kind of business to walk away from. I would add that ops are still an important piece of that puzzle. Not all, but some of revenue transferability does have to do with ops. They definitely don’t need to be perfect, since they can be fixed. On the tech side in particular, I’d walk away from a tech deal if the underlying software was beyond end-of-life. Opens up a can of worms of a ton of work and a real risk of that business disappearing in an instant.

@redacted‌ fair point and I agree ops matter. But your end-of-life software example is actually a top-line problem: you have a product that can no longer be sold competitively. The operational debt has already metastasized into a revenue risk. That's exactly the kind of issue that gets categorized as a fixable operational problem in diligence when it's actually existential. The line between ops and revenue isn't as clean as we'd like it to be, and when the product crosses the usable-life line, it stops being an operational problem entirely.
