Hi- apologies if this is posted in the wrong section. I'm a new subscriber.
I have a few clients for whom I manage ad spends. When bringing on my most recent client, she was surprised by how high my price was. Without revealing anything too personal or giving away trade secrets, I would love to know how other spend-managers structure their costs, ie: just a percentage? Incentive-based?
Any advice would be appreciated. Again, apologies is this is off-topic.
