# How do I enable the Zoho Books module in Zoho CRM?

**Pre-requisites** to enable the Zoho Books module:

*   All **Accounts** / **Contacts** should be set up as a two way sync.
*   **Items** sync should also be a two way sync.
*   If the **Purchase Order** module is enabled in Zoho Books, the **Vendor** sync should be set up in a two way sync.

**Pre-requisite** to set up Zoho Books - Zoho CRM integration:

*   The user setting up / updating the integration must be an admin in all the Zoho finance applications i.e. a Zoho Books organization could be integrated with other finance products such as Zoho Expense, Zoho Inventory or Zoho Subscription. If it is integrated, only the user who is an admin in all the Zoho Finance applications can set up the integration.

To enable the Zoho Books module, click the **Enable** button under the **Sync Transaction Modules**.
