How can I integrate my Zoho CRM account with multiple Zoho Books organizations?

Note: The first Zoho Books organization that is integrated with Zoho CRM will have a two-way sync. That means all the customers, vendors, items and transactions in Zoho Books will be synced with Zoho CRM and vice-versa. The subsequent Zoho Books organizations will only have a one-way sync. That means all the customers, vendors and items in Zoho CRM will be fetched only from Zoho CRM into Zoho Books, and not vice-versa.

Note: To set up two-way sync, the base currency of Zoho Books and Zoho CRM should be the same. However, it is possible to set up the one way sync even if the base currencies of both applications are different. But, in this case, the Items (Products) sync cannot be configured if the base currencies are different.
