> One product of mine takes reports that come in as a table that’s been exported to PDF

Here's the first problem!

I can't believe actual businesses think that a report is anything other than for human eyes to look at. Typesetting (and report generation) is for presentation, and otherwise data should be treated like data.

I mean it's a different story if the product is like "we can help process your historical, improperly-formatted documents", but if it's from someone continually generating reports, somebody really should step in and make things more... computational.
