Could you expand on that? How are you differentiating between a 'booking' and a 'sale'?
My interpretation of this was that bookings == 'contractually agreed upon commitments to buy' (basically, sales), and then revenue flows thereafter, so if I sold a million dollars, and had $200k of churn in june, my June bookings would be $800k.
Are you referring to a 'sale' as some sort of 'customer has stayed past a probation period and the salesman is eligible for a commission' point? I'd love to have this cleared up.
Sale and cash are well understood in accounting circles. "Forward booking" is, I understand, much fuzzier. What may count as a sale (eg, I receive a purchase order) may differ from the forward booking (someone scribbles on an MoU).
Depending on the organisation, sales staff can be paid at different times in that pipeline. And unsurprisingly there's dropoff at each stage.
I guess I should end by pointing out that I am not an accountant and this isn't accounting advice.
In particular, that bookings come before sales come before cash, and that the three are reported independently.
