I work with a client who delivers professional qualifications.  The accounting for this is complicated and involves either invoicing in full and then treating this as deferred income OR setting up Direct Debits for staged payments.

For the deferred income there has been a use of a journal but this has created an issue where the visibility of this income is not easy to see in Books, how do others deal with deferred income and how does Zoho recommend dealing with deferred income in this case?
