I want to merge some billing PDF files together and format the output PDF files to PDF/A files

I have some pre-purchase questions, please. I need to know about your product. I would like to purchase today if possible. Could I get someone to contact me by phone?

Sample questions:

I am going to write a command line utility to merge some billing files together. This will be running on a Terminal Server (and on my PC for development and testing purposes). There are usually 2 people performing billing functions. I want anyone on the terminal server to be able to use the utility (since we may cross train people later).

  1. Is the output file formatted as a PDF/A?
  2. Are there any limitations for file size (This should not be a problem / I'm just curious)
