Note: This feature is available only for certain plans of Zoho Books. Visit the pricing page to check if it’s available in your current plan. Furthermore, the Custom Reports feature is available only in Profit and Loss, Balance Sheet, Cash Flow Statement, and Invoice Details reports.

To map a custom domain name, you have to add a CNAME record in your domain name provider’s website (e.g. GoDaddy) and then verify your domain name in Zoho Books. To do this:

Insight: The host name is usually your subdomain name. i.e, if your custom domain name is, your domain name is and your subdomain name would be billing.

You won’t be able to proceed until we verify that your CNAME record reflects on the DNS server. However, a newly created CNAME record could take a while to reflect on the DNS server. This depends on your domain name provider’s TTL (Time to Live) settings. You can contact your domain name provider’s support if you need further assistance with adding a CNAME record.

Note: When you set up a custom domain, your domain name will be shared with Zoho Creator.

Certificate Installation

SSL certificates help create a secure connection between a web server and a user’s web browser. Having an SSL certificate installed for your custom domain will prevent access errors for your customers.

As soon as your domain name is verified, we’ll start installing a multi-domain SSL certificate for your custom domain. This usually takes around 3-5 business days. Once this is done, you can access Zoho Books with your custom domain name. You’ll be notified by email when the SSL certificate has been installed.

Deleting and Changing Your Custom Domain

Once you’ve deleted your custom domain, you can start the mapping process again and associate it with a different domain name, if you wish to do so.
