A new Projected Revenue Report is now available in UBO, specifically under the Billing category of the Report Center.
You can now generate this report to show your estimated future revenue based on your subscriber’s current data based on the selected start month and projected number of months. It contains all future full-term and custom recurring invoice charges that will generate within the given projection months that you have provided, taxes not included.

Since this is an estimated projection report, you will not be able to go back to the period before the current month. This report also includes the total amount by ISP Site.
With this new Projected Revenue Report, you can now figure out what your expected revenue should be for the provided projection months, with the assumption that your subscribers pay their balance.
