Our business uses deferred income, and my accounts person makes an excel sheet everything month to calculate it (I only discovered this the other day)

Having revied the invoice API, it would be awesome if

1) A field called diferredincome to the invoice item, so that we can flag an invoice on creation as diferred, and export that information via the api. The field value would be number of months. E.g. a difered invoice over a year would have the value of 12.

2) Create a diferred income report using this data.

3) Create the journal entried for the diferred income.
