The systems crunch have in place make the accounting side of things fairly straightforward and intuitive. The team is pretty patient with people like myself, who are horribly bad at dealing with accounts, and they are always polite and helpful (thanks for remaining calm with me). A couple of small gripes would be that the turnaround times on additional services - especially if being paid separately for - need to be a little quicker. I'd probably also prefer an allocated accountant, even if it is just for the issue I'm dealing with, rather than someone new picking this up each time. I understand though that you are dealing with a large number of enquiries. If you are looking for a solution where you have degree of flexibility then this could certainly fit the bill.
