Retainer Packages At Whitsell Consulting, 95% of our clients work on a retainer basis. This benefits the client by keeping a consistent monthly bill and ensuring that a talented staff member is always available. Retainer packages are extremely flexible and allow for hours to be "banked" for a specific project, hours to be rolled over into the next month (based on terms of contract), and hours can be borrowed ahead from the next month without having to pay overages. We also accept work on a flat-fee project and/or hourly basis. Please contact us to inquire on our rates for monthly, quarterly or yearly retainer packages or on our rates for a project bucket of hours and hourly rates.
