How Do I Compensate The Buyer's Agent - Wholesaling

[Anthony Street]

Let's say an agent brings me a cash buyer and I decide as the wholesaler to pay him/her part of my wholesale fee, how exactly do I compensate the agent or a better way to phrase the question how does title know to pay the agent? Will I need to have an agreement between me and the buyer's agent along with instructions on how to pay the agent and if so what type of agreement should I have with the buyer's agent. Hopefully, my question makes sense because I could really use some help with the one.
