Michael:
There are a number of Adagio consultants, including ourselves, with extensive experience with Adagio Job Cost. Job Cost is a significantly complex module to implement and use. Though members of this forum, possibly including some Job Cost end users but that is very rare, might be able to answer specific questions you ask it would be nearly impossible for someone on this forum to assist you with getting Job Cost working for your organization (its just too big a task for the forum). Please keep in mind that the responders on this forum are volunteering their time, there is a limit to how much time someone will be willing to volunteer.
If you have a specific questions please ask it and we will attempt to answer. If you need assistance with the broader problem of how to setup and use Job Cost then please considered asking your Adagio Consultant for assistance.
