I'd liken them to LEGOs. SAP sells modules (bricks) and integration (services to make the bricks do what you need).

They also sell some easy systems, like a LEGO car, but usually it's better to strip them down and reuse the parts of what you need is a house.

But the end result always requires you to cut/reshape the darn Lego bricks themselves, because the modules never quite fit the use case perfectly, so consultants are brought in to hack it all into some sort of workable shape.
