What "goes around, comes around."
Many moons ago, I was involved with a project where a paper company in Thunder Bay was looking for accounting software. The vendor that turned out to be preferred was called System Dynamics. They now have a web site.
They produce an Oracle-based set of accounting and manufacturing software. Not neat to most people, but useful to some.
Ran into someone looking for "serious manufacturing software" that runs on Linux, prepared to pay something. SDC seems to fit the bill. They may owe me a job, some day :-).
