I was thinking about Due Diligence this morning and how the process often impacts the sellers. Usually the reaction to the DD checklist is one of surprise, this often leads to frustration and annoyance during it.  Most business owners only really meet due diligence when they’re already in the middle of a sale.
At that point, it can feel a bit like being cross-examined.

Endless questions. Requests for documents you haven’t looked at in years. Follow-ups on things you didn’t think mattered. It’s no surprise it can feel intrusive, even slightly uncomfortable, but it shouldn’t. A simple way to think about it. If you were about to spend £40,000 on a car, you’d ask questions. You’d check the history. You might even get a mechanic to go over it properly. Now imagine you’re spending £30 million. Suddenly, that long list of questions doesn’t look excessive. It looks entirely reasonable. Buyers aren’t asking for the sake of it. They’re trying to answer two very basic questions. Is this business about to fall over? And can it actually deliver what we’re paying for?

If the answer to either is uncertain, value starts to erode very quickly. There’s also a point that often gets missed. Due diligence is not just about what you say, it’s about how you say it. Slow responses, incomplete answers, or small inconsistencies all create doubt. And doubt is expensive. On the flip side, a well-prepared, responsive seller sends a very different signal. This is a business that is organised, credible, and ready for scrutiny. That tends to support value rather than chip away at it. So yes, due diligence can feel heavy. but it is not a hurdle designed to trip you up. It is simply the buyer doing exactly what you would do if you were writing the cheque.
