We bill customers for services that will be delivered over the course of a year, or multiple years. Sage does not appear to have an elegant way to track the deferred income, without multiple rjournals every month to tidy up a separate deferred income NL code. Is there not some add on that allows Sage to better handle future/deferred income to be recognized when it is earned, simply by entering the start and end date of the invoice "cover" dates?
