Hi,

To use your own custom domain name instead of the default odoo.com URL, you must configure your domain's DNS settings and update your Odoo database settings. The exact process depends on how you host Odoo.

If you are using Odoo Online (the SaaS version), you can purchase a domain directly through Odoo in the Settings menu under Website → Domain Names. Alternatively, you can use an existing domain you own by logging into your domain registrar's website and creating a CNAME record that points www.yourdomain.com to your Odoo database's address (your-database.odoo.com). After this DNS change is made, you must add the domain in the same Odoo settings page to finalize the connection. Odoo Online will automatically handle the SSL certificate for HTTPS.

If you are using Odoo.sh or a self-hosted installation, the process involves similar steps but with different server configuration. You still need to point your domain's DNS A record to the public IP address of your Odoo server. The key additional step is configuring your web server (like Nginx) to recognize the new domain and ensuring it has a valid SSL certificate, which can often be done automatically using services like Let's Encrypt.

In all cases, after changing DNS records, there will be a propagation delay of up to 48 hours before the domain becomes fully active and accessible worldwide. The primary control point for managing domains within your system is always found in Odoo's Settings under the Website → Domain Names menu.

Hope it helps
