Migrating from Crystal to XMLP Invoice: Ability to add conditional logic in XMLP Invoices

We are in the middle of investigating whether we should step away from the Crystal Invoices and move to XMLP before we upgrade to PeopleSoft 9.2. Main reasons to migrate:

• Ability to auto email invoices directly from PeopleSoft and getting rid of Custom program written to do this
• Ability to store Invoice Image to the Bill and getting rid of custom program and using external software to manage this.
• Stepping away from Crystal as is will be supported less and less

I have tried the delivered XMLP Invoice and from a setup perspective it seems very easy to change. The difficult part however is to get our Crystal template translated into the XMLP template.
