Yes, and no! Whilst bureau’s do not charge YOU a fee, they receive a commission from the speaker for their role in facilitating the introduction. Therefore, speakers have either pre-inflated their fee’s to incorporate this, or are taking a reduced payment to cover the cost of membership of the bureau.
It may therefore, prove more cost effective to negotiate the best rate for their services.
Again, to remain transparent, the level of investment I request directly from the client, is exactly the same level of investment I require if paid via the bureau, who therefore ADD their commission to my fee before passing these details to the client.
