SHARE

UCaaS providers combine multiple communication channels into one interface, preventing miscommunications that negatively impact customer experience and team productivity. With UCaaS, conversations are picked up right where they left off, even if those conversations took place across multiple channels.

UCaaS benefits include cost savings, improved internal collaboration, streamlining all external communication channels, and greater employee flexibility.

Here, we’ve provided a brief summary of what is UCaaS, features, pricing, and user experiences of the top UCaaS providers.

What is UCaaS?

Unified Communications as a Service (UCaaS) is software that streamlines and unites all business communication channels and third-party software integrations within one unified cloud-based platform.

UCaaS solutions centralize and synch the most popular communication and collaboration channels in real-time, including:

  • Voice calling/conferencing
  • Business SMS text messaging
  • Video conferencing
  • Instant Messaging
  • Live Chat messaging
  • Email
  • Social media messaging
  • Online faxing

In addition to simplifying business communications management, UCaaS companies provide valuable insight into customer journeys, customer support, employee presence/productivity, and more.

Plus, the scalability of the cloud means you don’t have to pay for the features you don’t need. Instead, you can create a communications solution that’s tailor-made for the current needs of your company, but can also grow with your business in the future.

 

How Does UCaaS Work?

The best way to understand how UCaaS works is to focus on the “as a service” aspect of the tool.

First, let’s break down the definition of “Unified Communications” (UC.)

Unified Communications is a united interface/dashboard that provides access to every communication channel your business uses in one place, eliminating the need to constantly switch between applications.

Think of UCaaS as a subscription-based means of deployment for unified communications, as UCaaS (unified communications as a service) is what actually gives business access to unified communications (UC) capabilities.

With UCaaS, companies don’t have to create their own central communications hub from the ground up. Instead, they can access unified communications from the provider’s cloud services.

Because UCaaS works over the Internet, there’s no need for businesses to purchase expensive, bulky hardware.

UCaaS is also much easier to use, as it requires little to no user knowledge of software development and tech support. This is because UCaaS providers, not users themselves, handle the backend data center, security, functionality, cloud hosting, and setup. This means there’s also no need for a business to invest in its own in-house IT team.

UCaaS providers users integrate their contact center and existing CRM tools into the platform to further streamline their internal and external communications systems.

 

UCaaS vs. VoIP vs. CPaaS: What’s The Difference?

Voice over Internet Protocol, or VoIP for short, is not the same thing as unified communications.

Instead, VoIP is a part of your overall UCaaS platform.

While both tools allow for communication over the Internet from desk phones, smartphones, and other mobile devices, UCaaS provides more robust business communication capabilities.

VoIP is used primarily for telephony communication, whereas UCaaS systems include Internet voice calling, chat messaging, email, video conferencing, and more. VoIP systems have advanced routing, IVR, and voicemail features that can be integrated into the UCaaS platform. For more information about the difference between VoIP and UCaaS, make sure to read this piece.

The difference between UCaaS and CPaaS (Communications Platform as a Service) is a bit more complicated.

Both provide additional communication channels to businesses — it’s the way they go about it that’s different.

UCaaS solutions offer a multichannel communications platform that is essentially “ready to go” right out of the box. CPaaS, on the other hand, relies on individual communication APIs to add individual communication channels to existing applications. This means CPaaS users will need to have much more technical knowledge and experience than UCaaS users.

 

The Benefits of UCaaS

UCaaS offers several benefits to your business like:

  • Reduced communication costs and scalability
  • Team flexibility and mobility
  • Increased security and reliability
  • Stronger, more personalized customer communication
  • Increased productivity and collaboration

 

Let’s take a look at each of these benefits in more detail below.

 

Lower Communication Costs 

Research shows that switching to a UCaaS provider can save businesses up to 30-50% of current operating costs.

UCaaS systems help to lower operating costs by:

  • Reducing IT staffing costs
  • Negating the need to purchase expensive hardware (decreased upfront costs overall)
  • Providing unlimited VoIP phone calling minutes
  • Optimizing employee activity and scheduling
  • Offering scalable solutions that ensure businesses don’t pay for features and users they don’t need/want
  • Creating better opportunities for revenue/sales growth

 

Team Flexibility 

Because UCaaS is available across multiple communication channels and multiple devices, it’s perfect for today’s remote, mobile workforce.

Employees have all the data and tools they need at their fingertips, no matter where they are.

This level of flexibility means companies are no longer geographically limited when it comes to who they can hire. Thanks to the remote-friendly nature of UCaaS, it’s easier than ever to invest in high-quality employees — and keep them happy.

Nearly 80% of team members say that they’re more likely to stay loyal to companies that offer remote work solutions, while others say they most appreciate the simpler, user-friendly nature of UCaaS companies.

 

Better Customer Communications

Your employees aren’t the only ones who will benefit from UCaaS implementation.

Unified solutions vastly improve the overall customer experience by:

  • Allowing customers to communicate on the channel of their choice
  • Integrating with CRM tools to provide agents with instant conversation/client history, meaning customers won’t need to repeat themselves
  • Making it easier for agents to provide personalized customer support and service
  • Increasing first contact resolution rates

 

Increased Security and Reliability

A study by Frost and Sullivan found that the two most important factors businesses use to evaluate a cloud services provider are security and reliability.

Though this may initially come as a surprise, the reality is that all the features in the world for the best possible price can never make up for poor security and unreliable tools.

When it comes to security, UCaaS providers offer:

  • HIPAA/PCI compliance
  • End-to-end encryption
  • Third-party security certifications (GDPR, SOC II, etc.)
  • Advanced administration controls and user management
  • SSO/multi-factor authentication

When businesses host platforms themselves, they often leave themselves open to major security threats — many that they may not even be aware exist. The provider manages all security measures in an offsite data center, monitors activity 24/7, and can instantly identify and act if an issue is detected.

The same goes for network reliability.

UCaaS platforms have multiple servers in different parts of the world (called “geographic redundancy.) This helps them to ensure they provide an uptime of at least 99.9% — a high level of reliability.

 

More Productivity and Collaboration 

A study from Cisco found that over 3/4 of UCaaS users report an increase in productivity levels after switching to a unified platform.

Real-time team collaboration features like instant chat messaging, user presence, and file co-editing/storage increase productivity while lowering the chance of miscommunication.

Collaboration and cross-channel team communication are especially essential for today’s remote and blended workforce, and UCaaS tools make it easy for users to connect with each other.

Our study on the State of Unified Communications found that over 80% of teams feel the collaboration features UCaaS software includes vastly improve productivity levels.

Plus, UCaaS automates several time-consuming, tedious business processes so your team can stay focused on and devote more time to what really matters.

UCaaS analytics also make it easier to review employee engagement levels, so you can quickly identify performance issues or common problems before they get out of control.

Additional Business Communications Tools

Looking for more in-depth reviews of the options we’ve mentioned here? Unsure if you need a UCaaS system or another communications platform like Cisco, Intermedia, Fuze, or Zoom?

Our interactive tables on call center software, enterprise voice over IP, and hosted PBX systems will help you learn more about all of your options for business communications.

UCaaS pricing generally ranges anywhere from $20.00/user per month to $45.00/user per month.


Prices of UCaaS systems vary greatly based on the number of licenses, kinds of features, and provider chosen.


Providers are often less transparent about UCaaS pricing than they are about other business software and solutions. In many cases, you'll need to contact the provider directly to ensure an accurate quote. 

Every UCaaS solution should include the following six functions: 

  1. VoIP Voice Calling
  2. Web Conferencing (audio and video)
  3. Internal Instant Team Chat Messaging
  4. Cloud-based hosting
  5. Flexibility and Mobile Communications
  6. Unified Communication Interface 

The most important UCaaS features include: 

  • Unlimited voice calling
  • Voicemail-to-text and email
  • Call forwarding, call park, call routing call waiting

  • File sharing and co-editing
  • IVR and virtual receptionist
  • Instant video meeting feature
  • Call analytics
  • Call recording
  • SMS and faxing

The difference between UCaaS and CCaaS is that UCaaS (Unified Communication as a Service) is mainly focused on improving internal business communication between team members, while CCaaS (Contact Center as a Service) focuses primarily on customer communication. 


Both UCaaS and CCaaS may have features that improve internal and external communication.


However, CCaaS is centered on finding opportunities to improve customer service and the overall outward-facing customer experience; while UCaaS looks for ways to simplify and streamline internal communication between individual agents and departments.
