UCaaS and CCaaS sound so similar that people often confuse them for the same thing. And while they’re closely related, they aren’t quite the same.

UCaaS, or Unified Communications as a Service, is a way to streamline video conferencing, audio calls, instant messaging, team collaboration, and other messaging tools into a single platform.

On the other hand, CCaaS (Contact Center as a Service) is a different solution because it’s meant to unify customer-facing communication instead of internal business communications.

Of course, there are a few more key differences between these systems, but UCaaS and CCaaS generally accomplish similar tasks—it’s just that they do so for different business sectors.

By understanding how these services differ beyond their packaging, you can find providers that serve your company a faster, more cost-efficient communication framework going forward.

Where the UCaaS vs. CCaaS Difference Matters


UCaaS solutions take a broad approach to improving the infrastructure of business communications. They provide a single platform from which businesses can manage all of their messaging and calling tools, such as:

  • Video conferencing apps
  • Audio conferencing apps
  • VoIP (Voice over Internet Protocol) services
  • Instant messaging platforms
  • Team collaboration apps
  • Mobile device integrations

Businesses these days have tons of communication-enabled processes; they require interactive voice response systems, integrations with other technology systems, mobile device access controls, and unification across shared networks.

This is all just a fancy way of saying that everyone in your business needs to be able to access and engage with the communications tools you use in an effortless and convenient way. But as easy as it is to say, it’s a lot harder to pull off without a UCaaS solution linking everything together in one platform or place.

If you’re still on the fence about the benefits of a UCaaS solution, consider the rising importance of remote and hybrid work options, especially in terms of employee retention. As more job-seekers are favoring remote work options, for example, competitive businesses have to find ways of collaborating, communicating, and conferencing with efficient solutions that won’t slow down operations.

For a lot of businesses, UCaaS is the most future-proof of these solutions—and it’s deliberately marketed that way as well. A business that uses UCaaS can upgrade its internal communications framework to meet new industry standards while also avoiding the pitfalls of having siloed or disparate communication tools that can’t intercommunicate.


CCaaS is an app-unifying communication framework that’s tailored more toward sales and service teams, with a major focus on the call center industry.

If your business runs a contact center, you know that your operations involve numerous apps and other lines of communication. These include inbound and outbound calls to customers, internal team networking, conference calls, emails and chat services, social media support portals, and more.

With this kind of setup, customers can contact you from multiple channels. This means that, if you want to have a modern contact center, you need to be able to consolidate all of those parts into one.

Think of a multichannel customer communication system as having a pile of multicolored yarn—everyone has to scramble to find the end to their piece, whether it goes to a phone line, a social media account, a chatbot, or whatever else. With CCaaS, that pile of yarn gets turned into a neatly designed sweater, and everyone can see how their thread fits into the overall pattern.

Apart from providing a cute analogy, this condensing and unifying of communication processes has tangible benefits for modern contact centers, including:

  • Enabling a multichannel approach to customer queries
  • Reducing downtime
  • Assessing the effectiveness of customer service solutions
  • Identifying the contact center’s weaknesses or pain points
  • Increasing customer satisfaction

In this case, the main difference between UCaaS and CCaaS systems is not so much about what they do, but instead, it’s about what kind of businesses they are optimized to do it for. Thus, whether your own company would benefit more from UCaaS or CCaaS depends on how important it is for your employees to communicate with each other as opposed to how they communicate with your customers.

What Both UCaaS and CCaaS Include

Essentially, what CCaaS does for the digital customer experience is what UCaaS does for internal business communications. Just as team members are more productive using UCaaS solutions, contact center agents will also have an improved workflow that can better address customer queries across multiple channels.

Keep in mind that both solutions can optimize your internal conversations, improve collaboration between teams, unify different communication channels, integrate with productivity apps, and scale to meet the needs of growing businesses. However, they don’t necessarily do it the same way.

For example, CCaaS includes chat and social media support to help contact center agents reach out to customers on multiple channels. UCaaS doesn’t need those features because the businesses that benefit from it are not looking for a better customer service model. That’s why it goes for internal collaboration tools instead, prioritizing file-sharing apps and video conferencing features.

Each solution’s ability to integrate with the business technology you already have is another huge difference you should know about. Businesses that would benefit from UCaaS probably need a solution that can integrate with calendars, productivity applications, call logs, team collaboration platforms, and so on. Once again, the target is how employees talk to each other, and CCaaS isn’t looking to do that—instead, it’s integrating with customer data programs and CRM systems to help call center managers improve their customer service channels.

In other words, UCaaS and CCaaS perform similar functions on paper, but the people they target and the systems they strive to unify are different because the businesses that benefit from using them differ as well.

UCaaS-Specific Features and Capabilities

UCaaS offers specific features and capabilities to enhance your internal communications. As previously mentioned, it unifies business applications used for video conferencing, instant messaging, internet calls, team collaboration, and more. This allows employees and clients to connect seamlessly and avoid certain problems with conventional phone systems that require real-time connectivity to share information.

Like CCaaS, UCaaS also allows your employees to offer better customer support since your agents can see and address queries more promptly. When UCaaS is fully optimized, businesses typically notice improved customer satisfaction scores because better communication tends to beget better and/or faster problem-solving.

Since UCaaS can easily be integrated into the systems your business already uses, scalability becomes a clear benefit as well. New users and functions can be added and subtracted whenever necessary, and your IT people don’t have to go to each of your physical locations to update or change any software since it’s all unified through a single network.

Businesses also find a lot of cost savings by eliminating some or all of their needs for expensive hardware, on-site maintenance, and instances of overstaffing. And since UCaaS is usually offered on a subscription basis, companies can even use it to predict their operational costs a bit better as well.

That said, UCaaS has some potential drawbacks. For example, it can be a complex system to integrate—especially if your business has a ton of existing communication tools. The implementation process can also be expensive—in addition to being complicated.

Finally, UCaaS also relies heavily on the stability of your business’s network. This means contingencies need to be in place in case of power outages and other disturbances—because when the only network that exists goes down, everything else goes down along with it.

CCaaS-Specific Features and Capabilities

CCaaS systems unify business communication tools related to the digital customer experience. The communication channels that CCaaS organizes are the ones you use to interact with customers, including live chat apps, phone lines, emails, and social media accounts. With everything in one network, your agents can offer more efficient and more personalized customer service.

Naturally, this consolidation improves agent productivity by promoting better multitasking and more efficient problem-solving. This also saves money because pay-as-you-go CCaaS services can easily be scaled up or down depending on what you need for each call center—or even each season of high volume or demand.

One thing that CCaaS places a greater emphasis on than UCaaS is real-time analytics, as these are the bread and butter of improving customer service performance. For example, CCaaS systems give you a dashboard with all of your KPIs so that you can see where your workflow is bottlenecking and what you can do to un-bottleneck it. They also integrate with CRM systems to help you optimize the full customer journey.

Despite these benefits, CCaaS users can also run into some drawbacks. Similar to UCaaS, it has a high upfront cost to implement, plus there’s usually a significant training period for your employees to get acclimated to the system.

CCaaS also depends on cloud-hosted internet services, so network disruptions can be an issue. Lastly, security issues can be a concern, as customer data needs to be protected with access control and anti-breach measures.

UCaaS vs CCaaS: The Popular Alternatives

UCaaS and CCaaS are both useful options, but they’re not the only ones. Here are some alternatives to consider if you’re shopping for communication systems for your business:

SIP: SIP or Session Initiation Protocol is a method for using an internet connection to make phone calls instead of relying on analog phone lines. This allows businesses to adopt multimedia communication apps like video conferencing tools and other messaging services into their framework.

VoIP: Voice over Internet Protocol is another way to enable audio-only communication over the internet without a phone line. Traditional businesses that conduct all of their marketing and sales calls/conferences over the phone may not need a multimedia solution, so a VoIP solution may be the only thing they need. Alternatively, it could also be the starting point for a completely revamped framework that includes UCaaS, free of phone lines and phone service plans.

CPaaS: CPaaS or Communications Platform as a Service will allow your IT people to get real-time communication apps into your business without messing with interfaces, programming, and all that nitty-gritty stuff. Like most other solutions in 2024, it’s a cloud-based system—and like UCaaS, it supports multimedia communication options such as video conferences, chats, and instant messages.

Unlike UCaaS, however, the main purpose of CPaaS is to allow developers to add features to your system (rather than creating a unified, cloud-based network for your communication apps).
