Having worked on ERP software for medium businesses, that sounds spot-on to me; in my experience the biggest challenge was not so much technical as getting clients to change their processes so they can be systematized in a sane way.

There is a lot of resistance from employees not willing to change the way they work. Even seemingly simple things like standardizing language / glossary between departments so we can have a single representation in the system can be an uphill battle.

As an employee of organisations I can tell you one reason for resistance: this sort of systematization ends up being endless meaningless churn.

Same for me, working on MRP-ish software for small businesses.
