The document outlines 3 things that a marketing firm may not tell a potential client. 1) They may outsource many of the services they offer to freelancers, so the client does not know who is actually doing the work. 2) The firm may try to sell unnecessary services that the client does not need. 3) The firm may not mention that the client needs to be involved in the marketing strategy for it to be successful, as no one knows the customers better than the client.
