Yes, at the very least "project management software" and "property management software" are already commonly using that acronym. Someone else already mention the more appropriate "personal knowledge base".
As a woman, my first reaction to something being named "PMS", I'd book it in the "insensitive" category. I know lots of other women will too. We've heard a few too many PMS remarks from men to not have a reaction.
It's not just insensitive if it's insensitive to you.
