I hope this is the correct place where I could ask this question. My mother is an accountant with a degree in economics. She works as a freelancer and she needs some licenses for her job.

The biggest problem is adobe acrobat standard, which costs 400€, quite a lot. I want understand if she must buy it to create pdf files or she can use some free (even for commercial use) programs that she has because of her job (the chamber of commerce provide some advantages to accountants).

She is actually using PDFCreator, which as I can read is free for business usage (open source also!!): http://sourceforge.net/projects/pdfcreator/

Thanks for any suggestion
