In Bill Prep, the entries will look strange (see the Article on Split Billing – Dividing Time Between Two or More Matters). If, when you create the actual (or draft) invoice you still see zeros for the hours, check to make sure the Matter is set up to use a Split Bill invoice style.  This can be done in File Maintenance Manager.  Call up the Matter and click on the Bill Delivery Tab.  Select the Split Bill Invoice style and click Save and Close.  Try printing your Invoice again.  If you do not have a Split Invoice Style available, contact Orion.
