Go to Prebill Manager, call up the Client-Matter and find the Fee Entry and/or the Expense Entry. Make sure and place a check mark in the Bill box and the Off box, what this will do is actually bill the entry, but it will not show up as a line item on the actual invoice. Make sure and zero out the amounts you wish to add to another Fee Entry and/or Expense Entry, then make sure and add those monies to the Fee Entry and/or Expense Entry with which you would like to combine it.
