This is part of the problem. Huge enterprise companies in this space primarily grow through acquisitions, leading to a huge patchwork of products in the same company all doing the same thing. ADP are kings at this—so many different versions of so many different products (again, all doing the same thing) that there is no one ADP experience. I think this is one of many reasons smaller companies are chipping away at these behemoths because the companies themselves (ahem, SAP) can't even keep it all straight.
