Whether you are switching agencies, bringing development in-house, or simply want a backup, a smooth website or app handover depends on preparation. Here is what to have ready before the transition happens.
Get Full Access to Your Own Accounts
Make sure you personally own, or at minimum have admin access to, your domain registrar, hosting account, website admin login, Google Analytics, Google Search Console, and Google Business Profile. These should be registered under the business’s own email, not an agency’s, so access never depends on staying with that agency.
Collect All Source Files and Credentials
Ask for a full backup of the website files and database, the app’s source code if applicable, and any custom plugins, themes, or integrations that were built specifically for you. Store login credentials for every connected service in one secure place rather than scattered across emails.
Document What Was Built and Why
A simple handover document describing the site structure, key integrations, and any unusual technical decisions saves the next developer significant time. Without this, a new team often has to reverse-engineer decisions that could have been explained in a paragraph.
Confirm Ongoing Service Dependencies
Many websites and apps depend on third-party services such as payment gateways, email providers, or SMS APIs. List out every external service your site depends on, along with which account it is billed to, so nothing breaks unexpectedly after the transition.
Plan the Technical Cutover Carefully
If you are changing hosting providers or making major changes during the handover, plan for DNS propagation time and test the new environment before fully switching over, to avoid downtime for your live website or app.
The Bottom Line
A handover goes smoothly when ownership of accounts, access to source files, and documentation are sorted out in advance. Treating this as a checklist rather than an afterthought protects your business from losing control of its own digital assets.
