There are many gripes agencies have with the RFP process. One of the main ones being that they take up so much non-billable time. WPP CEO Martin Sorrell wishes agencies would get paid for their submissions, but knows it’s just not going to happen.

“The RFP [request for proposal] process is still a long process and it’s all for free. WPP has participated in a pitch for a piece of work recently invoicing four major groups all for [no cost to the prospect] and in one global pitch recently we delivered a 36,000 page document,” he said at a recent PR conference in London.
