Unified Communication as a Service (UCaaS) Market Revenue and Trends

Unified Communication as a Service (UCaaS) is a cloud-based system that combines communication tools like phone calls, video meetings, instant messaging, and shared workspaces into one easy-to-use platform that you can access online. Moving away from standalone, relatively inefficient in-office solutions, UCaaS adopts a subscription-based approach whereby service providers operate the communications platform, upgrading it as needed, for all users involved. The cloud platform affords convenient, synchronized access to team members (regardless of their individual locations, devices, or time zones), while supporting the integration of UC capabilities with other core digital tools used by a business.

What are the Factors That Have a Significant Contribution to the Growth of the Unified Communication as a Service (UCaaS) Market?

Cost-effectiveness and high operational flexibility are the main factors stimulating the growth of the USaaS industry, as companies desire to reduce capital and go for higher business agility. By implementing a centrally hosted and subscription-based delivery model, UCaaS reduces investments associated with costly in-house infrastructure, hardware maintenance, and dedicated IT resources and “substitutes traditional hardware and other services that constitute the majority of Telepresence and Videoconferencing expenses and thereby 'converts the high capital costs that are associated with Telepresence and Videoconferencing equipment into manageable operating expenses.'" Flexibility makes another ‘key factor accelerating adoption of UCaaS, as it enables a company to add and remove services dynamically as workforce size, business requirements, or seasonal demand varies.' The system will be easy to deploy, remote workers easily accommodated, and everything easily adjustable.

Also, growth in mobility and BYOD (bring your own device) will be the future growth driver for UAaaS, as most companies are now bringing mobility into the workplace as a new strategy by allowing their employees to work from anywhere using their same mobile phones, tablets, laptops, etc. By enabling employees to access voice and video calling, internet messaging, and business productivity tools on their personal devices on the platform, companies can remain agile and improve the efficiency of decision-making as well as cut down on office hardware. BYOD reduces a company‘s hardware expenditure, improves employee satisfaction, leverages mobility, and gives access on any device and any platform.
