No, your company isn't special. Look at it from an engineering perspective. The law, by which I mean all laws that you operate under—local, regional, state-level, federal, international alike—is really not much more than a specification that you have to adhere to. More active markets and more rules and laws you're bound to just means a more complex set of specifications. Just like in the software world, we need a process, an implementation to adhere to that specification in order to do business by it. And at the end of the day, if two different implementations are compliant to the same specifications, the complexity of moving from one to another is always going to be minimal. One particular caveat is even similar to software engineering: if you're doing special, non-standard stuff outside of the spec, you should probably not be doing that at all.

This is a fun analogy, but in the world of enterprise-level business, the business often is software. Entire businesses today are ran by software, and that software is written according to the same set of specifications: the law. The small particulars that don't have to do with law or common business practices are pretty much reducible to implementation details.

SAP is one such very comprehensive implementation, that is very possibly the only software suite that has a nearly full coverage of the entire "spec" for business purposes. If you can't translate your business operations to SAP, beg your pardon for my abrasiveness but you're doing things wrong.
