This is what I always said; you change your company to adapt to SAP, not the other way around. Then you chose the wrong product. SAP has everything and then a billion configuration switches which should match what you want; they say they would want you to adapt it to your needs by programming, but really it's not very good for that.
On the other hand I know some consultants making millions by creating customizations to SAP specific in their vertical and then sell that as a packaged product to all competitors. Usually these products are incredibly niche (like a specific workflow for Scandinavian utility companies that implements some stuff all Scandinavian utility companies require by law but SAP does not provide. Picking between then implementing it by hiring Accenture or buying off the shelve from someone who did this before is easy.
