In our experience, it takes a minimum of 6 months to begin to effect the kinds of organizational changes that create lasting habits and processes. Our standard agreement is for a minimum of 6 months with an option to renew by the client thereafter for a “month to month” or longer “90 day” or “180 Day” term based on our rates in effect at that time. Both parties have the right to cancel after 6 months with 30 days written notice.
