You're being extremely uncharitable. Look, business processes are different at every single company. Especially between companies doing the exact same thing.

You're being extremely uncharitable. Look, business processes are different at every single company. Especially between companies doing the exact same thing. Which means that the software ostensibly doing the exact same thing at each of these companies is going to vary dramatically. Because the software at a company aligns to the business processes of that company. This is the true heart of Conway's law: "organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations." And there is no fixing this. It's baked directly into the axioms. If every company in a domain ran exactly the same way, there would be no such thing as a competitive advantage.
