Custom Domain Mapping

The Custom Domain Mapping feature allows you to access Zoho Books with a custom domain and also set a sub-domain name for the client portal that is accessed by your customers.

For example, if your organization’s name is Zylker and your website is https://zylker.com/, you can now create a sub-domain https://books.zylker.com/, and map it to Zoho Books. Following this, you can access your Zoho Books organization at https://books.zylker.com/ instead of https://books.zoho.com/ and  your customers can access their customer portal at https://books.zylker.com/portal/.

Prerequisite: A Professional plan of Zoho Books or a paid plan of Zoho Finance Plus or Zoho One.

Note: Your custom domain (https://books.zylker.com/) will be redirected to https://accounts.zoho.com during log in. However, your customers can directly sign-in to their portal login (https://books.zylker.com/portal/).

Mapping Your Domain Name

To map your domain name, all you have to do is:

  1. Set up a CNAME in Domain Name Provider’s Admin Portal.
  2. Request a Custom Domain in Zoho Books.

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:

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

Sub-domain Name  CNAME
books books.cs.zohohost.com 

Similarly, if you wish to use billing.zylker.com

Sub-domain Name  CNAME
billing books.cs.zohohost.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:

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.
