This article is part of a larger series on Unified Communications.
Unified communication as a service (UCaaS) provides a centralized platform that bundles cloud phone, video conferencing, and team messaging. Communications platform as a service (CPaaS)’s cloud-based collaboration tools are designed to be added to existing business applications. CPaaS is typically the cheaper option but is more difficult to deploy. Determining whether UCaaS vs CPaaS is better for your business then depends on your needs and budget.
Based on our comparison, the best use cases for UCaaS vs CPaaS are the following:
- UCaaS: Best for most small businesses that need an all-in-one ready-made platform for communications
- CPaaS: Ideal for businesses with in-house dev teams wanting to create truly customize communication infrastructure

When To Use UCaaS
Businesses use UCaaS to access a wide variety of communication tools—text, voice, and video—all in one interface. UCaaS solutions often come in the form of business phone services that integrate communication channels, such as email, live chat, virtual fax, video calling, and short message service (SMS).
If your company is looking for an alternative to on-premises unified communications (UC) tools, a full UCaaS implementation is a better choice. It offers a voice-over-internet-protocol (VoIP) system with cloud capabilities, such as telephony, voicemail instant messaging, and video conferencing. Even better, UCaaS providers include third-party business solutions, such as CRM systems—making them ideal for customer-facing environments.
Whether you’re managing an on-site, hybrid, or remote workforce, UCaaS makes it easier for all your teams to collaborate no matter where they are. For example, UCaaS solutions offer collaborative workspaces, including file sharing and project management from any location via laptops and mobile devices.
UCaaS is a great fit for businesses looking for a scalable communications platform to support their growth. Since most UCaaS platforms are billed per user, a company only has to pay for its employees while maintaining the flexibility to add more users as needed. More importantly, UCaaS offers a reliable solution that expands your communication capabilities without incurring additional costs.

Advantages & Disadvantages of UCaaS Service
A UCaaS system offers numerous benefits to businesses by providing all employees with the same set of communication tools in one platform wherever they are. However, it also comes with certain features that may affect the quality of its administration.
Here’s a list of the pros and cons to determine whether it’s a right fit for your business communication needs.
Pros of Choosing UCaaS
A popular benefit of UCaaS is the ability to access all communication channels in one platform. Instead of using multiple applications, UCaaS encompasses all business communication needs by creating a central hub for conferencing and team collaboration. This allows employees to get more done and stay on top of office activities.
Greater Employee Mobility
UCaaS connects remote and hybrid teams in many ways, whether through instant messaging or virtual meetings. Everything can be accessed on any device with the ability to switch between devices with one click. Team collaboration tools, such as file sharing and screen sharing, empower employees to stay productive and connected amid geographical borders.
Keeps Costs Under Control
Adopting a UCaaS service eliminates the need for on-premise installations and hardware maintenance. UCaaS providers offer more predictable billing cycles, including the number of users, features, and the cost of calling. However, businesses should choose their provider carefully—considering their exact needs to maximize the service and avoid any extra cost.
Enables Real-time Interaction
UCaaS makes it easy to respond immediately to urgent matters by replacing long email threads with instant messaging. This makes online meetings feel more like in-person communication.
Access to a Host of Communication Tools
UCaaS offers a broader feature set than other standard communication tools. These include third-party integrations, built-in security, enhanced scalability, and softphone features. For example, if a video meeting is ongoing, the user can also share their screen or files, enhancing the overall experience of the video call.
Cons of Choosing UCaaS
Potential Interoperability Issues
Migrating your on-premise UC system to the cloud potentially leads to bigger cost concerns if your UCaaS software doesn’t work well with your existing hardware. Outdated computer systems don’t integrate well with new UC technologies.
Steep Learning Curve
The cost of training is something to consider before switching to UCaaS. Team leaders and employees familiar with legacy phone systems require intensive training to fully adapt to the UCaaS ecosystem.
Requires Stable Internet Connection
Since UCaaS exists on the cloud, it requires an internet connection to access its services. A slow internet connection reduces the quality of the UCaaS experience.
When To Use CPaaS
The main purpose of CPaaS software is to deliver a more flexible, seamless, and customizable communications system than UCaaS. If you want to select the best tools for your business and integrate them seamlessly into existing applications, CPaaS is a better fit. It enables businesses to create an omnichannel strategy for their communications, leading to efficient operations and seamless customer experience (CX).
CPaaS platforms include bundle APIs, code snippets, and programming tools, enabling developers to improve and integrate real-time communications on an existing platform without needing a separate app. For example, CPaaS makes it easy for developers to create a pop-up box to help web leads ask questions as they navigate a website.
CPaaS is a great fit for businesses looking to grow their customer bases because it’s primarily focused on enhancing their customer communication channels. It acts as a platform that combines the reliability and back end of communication systems with your own customer service software through the use of APIs. This enables you to embed voice, chat, video capabilities, and even conversational AI in your customer-facing applications.
Advantages & Disadvantages of CPaaS Service
Both UCaaS and CPaaS have similar benefits when it comes to scalability, flexibility, CX, and cost control. However, CPaaS also has unique advantages for businesses that want to customize their communications infrastructure. It’s also worth noting that there are also challenges involved in the implementation.
Here are the pros and cons of CPaaS platforms.
Pros of Choosing CPaaS
Flexible Customization Options
CPaaS makes it easy to build programmable communications that suit the company branding, customer needs, and products/services. It offers the freedom to develop the tools you need through powerful APIs. CPaaS providers offer scalable a la carte communications solutions for business platforms.
Enriching Customer Experience
CPaaS platforms allow users to add different call functions, such as social media messaging and inbound call routing, to your current communications stack. The freedom to customize how you connect with customers makes it easy to reach them on relevant channels in real-time.
Bigger Cost Savings
With its pay-as-you-use model, adopting a CPaaS solution means paying only for the services used, so you have more control over the costs. There is no need to buy a one-size-fits-all solution when it’s possible to build an ecosystem that works for you. Adding new features to your existing technology via APIs involves less work and money than developing a back-end system.
Integrates With Other Systems
With CPaaS, customer service tools, such as chatbots and CRMs, become fully integrated. You need software tools to help your developers integrate them quickly within your existing applications.
Access to Omnichannel Capabilities
CPaaS supports the expansion of the number and methods of communication channels to interact with customers. An omnichannel approach enables customers to engage on their terms, leading to immersive customer interactions.
Cons of Choosing CPaaS
Multiple APIs May Lead to Latency Issues
Using too many APIs to your existing platform leads to speed issues, resulting in software lags or delays. Failure of data centers also leads to significant downtime. Overall, these issues could contribute to workflow inefficiencies.
Requires a Prebuilt Application to Function
Any CPaaS solution involves a great deal of customizability and significant developer resources. Since communications API lacks a built-in user interface (UI), businesses must develop their own interface for employees and customers.
Requires Coding Skills
To use CPaaS, you need developers with experience building customer applications via APIs. You also need devices and software that interacts with API endpoints.
