Joe:
Actually Sage ACCPAC ERP 500 will allow 45 character GL numbers. Can you imagine trying to deal with a 45 character account number!
I don't believe that Softrak has any plans to extend the existing 6 character account and 6 character department code as this is more than enough for anyones needs.
You yor prospect is using more than this then a plan to change them to fit Adagio can be made.
