While you're waiting for a reply, have you had an opportunity to read any of the documentation posted on The Exchange?
You can find just about anything you're looking for here:
Complete Guide to PracticeWorks Line Item Accounting
I hope this helps!
PS: I worked with all of the beta offices and may be able to reach out to one of them to call you. Would this be acceptable?
Also, in case you didn't know, we have several upcoming webinars on Line Item Accounting scheduled. You can find a list of them under the Events tab in the PracticeWorks space here on the community ( CS PracticeWorks Events ). A registration link is available with each of the event listings as well.
A long time LIA user will be reaching out to you this afternoon after 1PM.
