Handover & Training
Documentation and recorded walkthroughs built around the actual site, so nobody has to call an agency to change a phone number.

What does handover include?
Repository access, deployment access, analytics and CRM access in the client's own accounts rather than the studio's. Custom code documented rather than left as a black box. And recorded walkthroughs made against the real site, not a generic CMS tutorial, covering the things that team will actually do.
Why record video instead of writing a manual?
Because people watch a two-minute clip and do not read a forty-page document. Short, specific, one task per video, findable six months later when the person who was trained has left.
What if we want to move to another agency?
Then you can. Conventional structure, documented code, accounts in your name. A site should not be a hostage situation, and building one that is says more about the agency than the client.
