How does the Zoho Books - Zoho Inventory integration work?

The Way it works:

• On integrating Zoho Inventory with Zoho Books, all the data - settings, contacts, items, sales orders, purchase orders, bills and common reports are synchronized with your Zoho Inventory account.
• Henceforth, any new operation in Zoho Books will be reflected in Zoho Inventory and vice versa.For example: after you have successfully setup an integration, if you create a sales order in Zoho Books, it will be reflected in the sales order module of your Zoho Inventory.

Important Note: When importing items, only those items in Books that have inventory tracking enabled, will be synchronized into Zoho Inventory. Normal sales and purchase items will not be imported this way.
