Is it asking for the discrepancy between cash and accrual accounting (which seems to be what you stated) or is it asking what they are booking in accrual revenue?
This is one of those annoying things where I can talk about either concept, but don't know the language that serves as a proof of competency.
It probably requires some context based on the metrics that matter to a specific business. I'm not sure someone would ask the question that way where I am. (Not in finance, so may be wrong, but have been at numerous business reviews.)
Purely from the outside, I'd guess that yes they're asking for the discrepancy. Maybe they're asking for accrual revenue but I'm not sure I've ever heard the term used that way. I would expect someone would ask for bookings if that's what they wanted. (Which can get even more complicated for multi-year subscription deals.)
ADDED: It's been a long time since I got my MBA but, with all the data in front of me, if someone asked me that question, I'd have to ask what they actually wanted and, if they fired me a result, so be it.
