I would actually consider where in the world you are, and if your country mainly takes in stuff that is IFRS.
If it's all IFRS, multibook would be less useful, ARM will help you in all the modern requirements for revenue recognition related requirements. For when you sign contracts for the year, billed quarterly, these occurrences are more frequent imo versus requirements for you to require create multibook for non-IFRS support.
Say japan, probably Mulitbook is also more worth it, if only just for fixed asset reasons (straight line for IFRS vs reducing balance)
