Before handing a customized template to a client, clean classes, components, CMS fields, demo assets, permissions, forms, integrations, documentation and publishing responsibilities.

A customized website is not ready for handoff until the client can understand what they are expected to maintain. Clean the project and define ownership before transferring access.
Delete unused demo pages, placeholder CMS items, old logos, stock assets, test links and scripts the final site does not need.
Make component names, classes and shared styles understandable. Remove obvious duplicates created during experimentation where it is safe to do so.
Rename unclear fields, remove unused fields and explain required versus optional content. Test how Collection templates behave when optional values are missing.
Confirm who receives submissions and who owns CRM, scheduling, analytics, consent, chat or other external accounts.
Record what each script does, where it runs and which service or library it depends on. Invisible dependencies are difficult for clients to maintain.
Decide who can publish, who reviews structural changes and what happens when URLs or CMS schemas need to change.
Training should focus on common tasks such as publishing a project, editing a service or changing a team member—not every feature of the platform.
A professional handoff makes routine content editing boring and predictable while keeping structural changes controlled.
