Mapping Your Domain Name
To map your domain name, all you have to do is:
Step 1: Set up a CNAME in Domain Name Provider’s Admin Portal
CNAME is usually known as the canonical name for your domain. The CNAME is the alias name that is used to setup a sub-domain name for your organization. To setup a CNAME:
- Log in to your domain name registration provider’s website.
- Navigate to your settings and select DNS (Domain Name System) settings.
- Create a CNAME entry by entering the sub-domain name and the CNAME.
- Map the CNAME entry to books.cs.zohohost.com.
Based on your domain name registration provider, * The sub-domain name might be called: Host/Alias. * The CNAME might be called: Value, Points To or Destination.
For example, if you wish to use books.zylker.com,
Similarly, if you wish to use billing.zylker.com,
Once you have configured the CNAME entry, you can test it via nslookup command in the terminal to verify it before submitting the custom domain request. The changes may take up to 48 hours to reflect based on your Time To Live (TTL) settings. The TTL settings determines how long it takes for your computer to update its DNS related settings.
You can also contact your domain administrator or domain admin support if you face any difficulties while configuring your CNAME entry.
Step 2: Request a custom domain in Zoho Books
Once you have configured a CNAME in your domain name provider’s website, the next step is to request for a custom domain in Zoho Books. To do so:
- Click the Gear icon from your Zoho Books home page.
- Select the Preferences module and select Branding.
- Click the Custom Domain tab and enter your Domain Name (Example: billing.zylker.com) under the Enter your Domain Name field.
- Click Submit.
Note: Please do not submit any test domain. Once you submit your custom domain request, you won’t be able to edit or update your custom domain URL.
Installing an SSL Certificate
After submitting your custom domain request, if you encounter an SSL (Secure Sockets Layer) error, do not worry. Zoho Books will install a Multi Domain SSL Certificate in the back end to secure your domain name and prevent further errors.This process usually takes up to 3-5 business days.
You’ll be notified via email when your custom domain is active after that you will be able to access your Zoho Books organization using your custom domain name.
Note: SSL certificates helps you to create a secure connection between a web server and a user’s web browser.
SSL certificates from third-party vendors cannot be installed in Zoho Books.
