A marketing project fee is an agreement for a one-time deliverable to be completed within a specified timeframe at a set amount. Where retainer agreements are better suited for long-term relationships, projects are ideal for short term or one-time needs.  For example, project fees may cover web design, mobile app development, logo design, or setting up a social media advertising campaign for your business.

While you could argue that most marketing agencies are designed for retainer relationships (it takes time to generate results in marketing), even marketing services can be categorized as a project if the campaign has a singular focus to achieve a specific objective.
