The fashion design invoice is a transactional statement provided by a fashion designer (or design company) to the client that hired them. A client might be an individual trying to start a clothing line or a company already established in the fashion industry. Therefore, the costs associated with hiring a fashion designer can vary greatly depending on the project. In most cases, the designer will charge their client for materials as well as labor. Once the project is complete, a fashion design invoice allows the client to see what they have been charged for and how much they have to pay in total. The designer will give the client a specific time period in which they are obliged to make their payment.
