Recognizing 1/12th of Deferred Revenue (each month) over a 12 month service term

A software company invoices commercial customers annually for software maintenance (support) to be provided over the following year. For example, they may invoice a customer for $12K in December and then recognize $1K per month from the following January to December. The $12K is due within normal terms and typically paid sometime just prior to or in the first month or two of the "service period". Thanks for any help - it's possible QBOL is not robust enough to handle this efficiently and may need an add-on tool or replacing. Thanks for any help!
