More and more, smaller Agencies in particular are requiring quarterly/bi-annual/yearly allowances, that are really time consuming to manage manually.
I think that one of two things needs to happen;
We take a harder line on how we can sell mentions. i.e. monthly only.
Product creates a system to allow us to more easily manage these clients. So a quarterly/yearly tracking option, or a rollover option
I don't see the quarterly/bi-annual/yearly allowances as a problem, so long as the functionality is there to manage them.
