A mockup is a detailed, full-scale representation of a design which allows designers and clients to visualize the concept before it is implemented. Mockups can be incredibly useful for a freelancer when they are used properly, as they allow them to make sure the design fits the client’s needs and that any changes that need to be made can before sinking too much time, effort, or budget into the final project.
Freelancers can create a mockup of the design they have created so that the client can get a realistic view of the concept. This allows the designer to make changes and refine the design based on the feedback they receive from the client. The mockup also serves as a reference for the freelancer to refer back to when making changes or refining the design.
