A typical website project project consists of an out-of-the-box deployment of a pre-built theme / design on the most recent version of the selected content management platform (WordPress, HubSpot, SquareSpace).
The functionality of the web application is limited to what is included in the theme / design and native to the content management system.  Requested functionality that is not compatible with the out-of-the-box version of the software and/or requires creation of additional website development code (HTML, PHP, CSS, etc) is considered out of scope.
Customizations to the design of the out-of-the-box deployment and documented configurations for systems integration are intended to make the website specific to the client and are outlined in a scope of work.
