[Back](./) # I am using the Professional plan of Zoho Inventory and I have purchased the Zoho Books Elite plan. How do I map the existing Zoho Inventory organization to the Zoho Books Elite combo? It is possible to map the Zoho Inventory organisation to the Zoho Books **Elite** combo if the Zoho Inventory organisation ID is same as that of your Zoho Books organisation. With the **Elite** and **Ultimate** plans of Zoho Books, you get access to **Advanced Inventory**. Here’s how you map the organisation: * [Downgrade](https://www.zoho.com/inventory/help/subscription/subscription.html#cancel-subscription) the Zoho Inventory subscription to the **Free** plan. * Once this is done, write to us at [support@zohoinventory.com](mailto:support@zohoinventory.com) with the Zoho Inventory organisation ID that needs to be mapped to the Zoho Books **Elite** combo. We will make the necessary changes from our end. **Note:** When you downgrade the Zoho Inventory organisation, you will no longer be able to configure approvals for inventory transactions (Inventory adjustments and Transfer Orders). * * *
