Using these instructions you can create an invoice that displays the balance due amount when a client does not have any new activity to be billed for.
The process for creating a "Balance Due Only" invoice is essentially the same as a normal invoice. Just follow the four steps below.
1) Leave the Time and Expense date range fields blank.
2) Set the "Invoice Footer Format" to "Invoice Amount With Account Detail".
3) In the Flat Rate Line Item section set the description to "No new charges for this period."
4) Set the Flat Rate Line Item Amount to 0 (zero).
