The web design invoice is a billing statement for services completed by a web designer or a team of designers. Web design covers all areas of website creation and maintenance such as graphic and interface design, authoring, and search engine optimization (SEO). For large web design projects, a customer (the individual or company creating a website) will typically hire a team of designers to cover a wide range of services. A web design invoice will include an itemized list of services provided, along with a brief description of each one, and the cost or hourly fee of these services. The web design company will calculate all the fees and enter the total at the bottom of the invoice. The customer will be made aware of the payment due date so they don’t incur any interest fees or additional charges.
