It’s worth remembering that money is not always being made at the source. Just because you create, build, assemble… that’s where the thing to be sold is made, but it’s only in commodities like crude oil where the source is the point of maximum cash conversion. In many other cases, the outlet is where you get the most bucks for your bang.
Which again is just a paraphrase of the old mantra: know who your buyers are, know their needs, build a direct relationship, etc. etc. Even if your source doesn’t spew out a commodity, it doesn’t mean it’s valuable right from the start. Increasingly more stuff is less valuable to more people. Ignore this at your own peril.
