A retainer fee is like a monthly fee. Its perfect for those who know that they will need design services throughout the year and want to reserve a creative professional’s time. Since its purpose is to retain the designer, it is paid up front each month before work is ordered. Essentially, you are “pre-ordering” time versus a service. Since I will anticipate a preset number of hours of work from you, I will block out my schedule for the appropriate time each month. This gives me the ability to plan my workload accordingly. Which gives you the certainty of a pre-established amount of work each month without having to worry about what else is “in the queue” ahead of you. It’s more efficient for all involved.
