A ‘high-intent’ lead can still be the completely wrong customer

I learned something kinda annoying while building a lead-scoring system 😭
A “high-intent” lead can still be the completely wrong customer.
The company I was building it for gets a lot of inbound inquiries, and at first one signal seemed pretty obvious: quantity.
Someone asking for 200kg of a product sounds way more valuable than someone asking for 5kg, right?
Except... not necessarily.
That 200kg request could be a distributor looking for a bulk deal, while the smaller request could actually be coming from the exact kind of end customer the company wants.
So suddenly the problem wasn't just “is this lead hot or cold?”
It was: who is actually behind this inquiry?
I ended up treating customer type as its own signal instead of assuming that bigger quantity = better lead.
Made me wonder how often this happens in completely different businesses too 👀
If you've had an inbound lead that looked really promising and then turned out to be the wrong kind of customer — what was the misleading signal?
