I can only give advice based upon my own experience.

Using the various PDF-modules on CPAN is far from easy. Not only is the API rather complicated, there are almost no simple higher level routines to --for instance-- print a whole paragraph, nicely formatted, or even to add a paragraph to a page with automatic page-breaks and page numbering and the like.

That being said, there are a few modules which have a very specific functionality, such as PDF::ReportWriter which makes so-called business-reports, which are perhaps exactly what you are looking for. I used this module some-time ago, but as I needed additional functionality, I abandoned it and now write my reports on basis of Template::Toolkit-templates which output LaTex files rendered into PDF. It is totally flexible but it requires you to learn both the Template Toolkit language as well as LaTex!
