CCaaS will give you the data to deploy that $1M/year more effectively and may even help reduce your Human Capital needs. UCaaS will not be robust enough to make data-driven decisions on Human Capital or Customer Experiences.

Both CCaaS and UCaaS are multi-tenant cloud-based communication platforms. CCaaS will focus mostly on external communications with your customers to deliver excellent customer experiences. CCaaS can also be used to route calls to your internal or centralized group servicing internal stakeholders, like a HR Help-Desk or IT Help-Desk.  Meanwhile, a UCaaS platform will focus on internal communications between your employees for phone calls, instant messaging, and even meeting platforms.

The explicit callout of the as-a-Service signifies that these solutions are cloud-based alternatives to legacy on-premises platforms of old. The market saw increased adoption of as-a-Service telephony starting in early 2010’s. Adoption and platform capabilities recently sky-rocketed when organizations were forced to work remotely.

The investment in UCaaS is significantly less expensive than CCaaS solutions, but lack many of the important features that CCaaS solutions possess.
