Zoho itself calls it the operating system for business, and that definition is correct. On a technical side, Zoho One is a cloud subscription that covers most Zoho applications, such as Zoho CRM, Zoho Books, Zoho Inventory, and many others, in a single subscription with centralized user and license management. All the Zoho applications included in Zoho One are provided with the Enterprise functionality tier. You can get a free Zoho One trial or ask us to run a demo for you.
