Hi Everyone, I am being new to AI agency and I have two questions. I greatly appreciate your thoughts and sharing your experience. 1-Do you create separate accounts for individual clients in Make, Retell, Vapi, Chatgpt, etc? Or, do you create those accounts under your agency's main account? 2-How do you keep track of the costs associated with calls and how do you pass them through to clients? Thank you for the advice.
