Contact Center as a Service (CCaaS) enables more personalized customer experiences, offers real-time omnichannel communication, and improves agent management and efficiency.

While businesses are always on the lookout for software to improve customer services, many organizations struggle to understand what contact center as a service actually is — and what it does that their premises-based systems can’t.

Here, we’ll define CCaaS and explain how it differs from other “Software as a Service” communication solutions, go over the benefits it offers and features to look for and outline the best contact center as a service providers.

What is Contact Center as a Service (CCaaS)?

A contact center as a service (CCaaS) is a cloud-based alternative to legacy call center software and on-premise contact center software.

CCaaS technology sometimes referred to as hosted contact center software, is hosted and managed by the provider, as opposed to the organization using the CCaaS platform.

Contact center as a service solutions let businesses purchase common contact center functionalities like IVR and ACD, chat, different communication channels, and analytics, providing a higher level of scalability than many other customer communications software.

Call centers using CCaaS purchase monthly or annual subscriptions from the provider. They may add on features or upgrade to a higher plan tier as their communications needs grow and evolve.

Because the platform is hosted by the provider, contact center as a service users don’t need to purchase expensive hardware or have an extensive in-house IT team.


Cloud-Based vs. On-Premise Contact Centers

The below table sums up the main differences between cloud-based and premise-based (hosted PBX) contact centers.

  • Cost-savings and low upfront investment
  • API integrations easily available
  • Complete infrastructure control
  • Onsite servers provide peace of mind regarding security
  • Low latency
Potential Downsides
  • Relying primarily on the provider for support may mean extended support wait times
  • Relies on the stability/quality of the user’s Internet connection/bandwidth
  • High upfront costs
  • Requires employees to work in the office
  • Limited integrations


Call Center vs. Contact Center Software: What’s The Difference?

Call center and contact center software are both designed to improve the customer experience through features that strengthen communication between customers and agents.

The difference is that call center software, as the name implies, is focused primarily on VoIP voice calling, whereas contact center software offers omnichannel customer service and communication.

In addition to voice calling, contact centers provide real-time, synced communication between  devices on digital channels like:

  • SMS Texting
  • Video Conferencing
  • Live Chat Messaging
  • Social Media
  • Email


Contact centers will also integrate with third-party CRM software or provide native CRM features like customer contact cards, internal notes, and order history.

Above all, omnichannel cloud contact centers streamline business communication by providing a seamless transition between channels and allowing customers to choose how they reach out to customer support and sales teams.



CCaaS vs UCaaS vs CPaaS: Differences and Similarities

Before we go any further, let’s clear up these three similar acronyms within the business communication space.

Though the differences are subtle, knowing them matters when it comes to choosing the right kind of software for your business.


CCaaS vs UCaaS vs CPaaS


CCaaS stands for “Contact Center as a Service.”

CCaaS is a cloud-based business communications technology that gives businesses access to the provider’s contact center software and functionalities on an as-needed, pay-as-you-go basis. The provider themselves, not the business, owns, hosts, and maintains the contact center solution

The main goal of CCaaS platforms is to offer flexibility and scalability to businesses that want to use advanced CCaaS features to improve the customer experience. CCaaS focuses mainly on external communication. Popular CCaaS features include IVR, ACD, call queuing, and call routing options.


UCaaS stands for “Unified Communications as a Service.” 

UCaaS is also a cloud-based business communications solution hosted and maintained by the provider. UCaaS streamlines and automatically syncs real-time omnichannel unified communication services and collaboration within one united interface. The main goal of UCaaS platforms is to provide a central and unified omnichannel interface for internal and external communication across different channels.

UCaaS focuses mainly on eliminating the need to integrate multiple communication apps, and keeps users from constantly switching back and forth between applications. Popular UCaaS features include team chat messaging, video conferencing, SMS business text messaging, and cloud telephony.


CPaaS stands for “Communications Platform as a Service.” 

CPaaS is a cloud-based delivery platform that uses Communication APIs (Application Programming Interfaces) to add and customize individual communication channels like voice, video, RCS, SIP, or messaging to existing business applications or software.

Let’s say you’ve created a food delivery app (certainly an overcrowded space, but maybe you’re not one for creativity.) Lately, customers have been complaining that they can’t reach their delivery drivers. You want to give customers the chance to text or call their delivery drivers in your existing delivery app. CPaaS solutions like Twilio are what you’d use to make this happen.

With CPaaS, you’re not purchasing “plans” or “packages” including multiple communication channels. Instead, you’re picking and choosing which specific ones you want. CPaaS, then, requires much more IT knowledge and coding to implement and manage than CCaaS and UCaaS. There are no “built-in” features with CPaaS.

For more detailed information on the differences between these services, check out our posts on UCaaS vs CPaaS and UCaaS vs VoIP.



The Top Benefits of CCaaS Solutions

The convenience and accessibility of contact center as a service are just some of the reasons why so many customer-centric businesses are leaving legacy premise-based systems behind and migrating to the cloud.

Below, we’ll go over the biggest benefits of CCaaS software.


Cost Savings and Scalability

The most obvious benefit of contact center as a service is the immense cost savings it offers.

Because CCaaS users don’t need to purchase hardware, physical office space, or hire an in-house IT team, they’ll see thousands of dollars in savings on startup costs alone. Given that for every $1.00 invested in infrastructure, companies pay $2.00 to maintain it, the savings add up quickly.

Plus, since CCaaS is a “pay-as-you-go,” service, businesses avoid paying for excessive licensing fees and features they don’t want or need. Instead, they purchase the functionalities and number of seats they need at the moment and scale up over time.


Team Flexibility 

The pandemic has had just as much of an impact on how employees want to work as it has had on consumer behavior.

A 2021 Quantum Workplace study shows that only 11% of employees want to work exclusively on-site/in the office.

In other words?

Your consumers aren’t the only ones expecting the kind of freedom and flexibility CCaaS provides.

Because contact center as a service doesn’t tie team members to a single physical location, agents can work from anywhere in the world, from the devices they choose (including their own.) Since CCaaS software instantly syncs conversations across channels and offers real-time notifications, employees can seamlessly work across time zones.

This level of flexibility has big benefits for business owners, too.

Giving agents more options when it comes to how and when they work decreases employee turnover, lets companies pick from a wider pool of talent and access a greater diversity of skill sets, and even increases team member productivity by up to 77%.


Increased Productivity and Better Workforce Optimization

Increased productivity thanks to contact center as a service software doesn’t just come from the increased flexibility it lets businesses offer employees.

Analytics features give managers a birds-eye-view into what agents and departments are spending their time on, how long different kinds of tasks take, and the amount of time wasted on tasks that could easily be automated.

A more optimized workforce negates the need to hire additional team members, even during busier seasons. It also prevents certain employees from getting overburdened with tasks and other responsibilities while others remain underutilized.


Increased First Contact Resolution Rates

67% of consumers that stopped doing business with a company say they would have stayed if their issue had been resolved on first contact.

Having strong first-call resolution rates (FCR) doesn’t just decrease customer churn and the average call handle time. Research from SQM shows that for every 1% increase in first call resolution rates, a business’ total operating costs will decrease by 1%.

CCaaS solutions integrate with CRM software to show detailed customer history upon contact and provide routing solutions to connect customers to qualified, available agents. They also ensure agents have easy, instant access to internal wiki documents containing answers to common caller queries or customer service scenarios — drastically improving FCR rates as a result.



Contact Center as a Service Key Features to Look For

The hallmark of a quality CCaaS vendor is its ability to:

  • Improve the customer experience
  • Simplify the customer journey
  • Streamline business processes
  • Provide insight into customer and agent behavior
  • Maximize business resources without degrading support quality


The below CCaaS features make that and more happen, and are the top criteria to examine when comparing providers.


Available Communication Channels 

The most important thing to examine when evaluating a CCaaS platform is the available communication channels.

This doesn’t necessarily mean the provider that offers the highest number of channels is the best option. Instead, ensure the provider offers the real-time communication channels that your customers use the most.

For example, e-commerce customers will likely prefer to communicate via website chat and social media messaging — but probably not by telephone. Healthcare industry teams, on the other hand, may communicate almost exclusively through phone and email with their clients — but rarely on social media.

This is also where scalability plays a factor, as you should also ensure providers offer the channels your business may need in the future.


Customer Self-Service Options

Almost 70% of consumers today prefer self-service options over speaking with a live agent.

Self-service CCaaS features don’t just make your customers happy. They also leave live agents free to assist when more complex support issues arise, to make more outbound sales calls, or to follow-up on previous interactions.

Customer self-support features include:


Automation and Artificial Intelligence

Given that the workforce can spend as much as 40% of their time on routine, manual tasks, business process automation and Artificial Intelligence (AI) are integral to any contact center solution. These are the tools that save team members — and customers — major time by automatically completing routine, rote tasks.

They also reduce the risk of human error in data collection and speed up project timelines with features like automated approvals and status updates.

Contact centers software should offer AI and Automation features like:

  • Natural Language Processing (NLP) and Speech Recognition
  • Customer Sentiment Analysis
  • Automated customer information collection and storage
  • Automatic call logs
  • Automated follow-up scheduling
  • Real-time Agent Assistance


Security and Customer Support

Strong security and support features are a non-negotiable aspect of any business software, including CCaaS.

Key features to look for include:

  • End-to-end encryption
  • Third-party security testing
  • GDPR, HIPAA, PCI, SOC-2 compliance
  • ISO-27001 accredited
  • At least 99.9% guaranteed uptime and geographic redundancy
  • Automated updates and data backups
  • Meeting locks/password-protected meetings


Customer-Agent Interaction Tools

CCaaS software shouldn’t just make life easier for your customers — it should also help your agents stay organized, locate key information quickly, and keep track of support interactions.

Features (in addition to the automated functionalities mentioned previously) that help agents provide the best assistance to customers include:

  • Omnichannel routing with numerous routing strategies (skills-based, time-based, hours-based, round-robin, etc.)
  • Native CRM features/third-party CRM integrations
  • CTI screen pops
  • Workforce Management tools
  • Outbound dialers (predictive dialing, progressive dialing, etc.)
  • Drag-and-drop call flow design
  • Post-call notes
  • Searchable internal wikis
  • Call/contact scripts
  • Call forwarding
  • Call waiting, call hold, call transfer
  • Call blasting and ring groups


Third-Party Integrations and APIs

In addition to compatibility with your business’s current operating systems, Internet browsers, and devices, you’ll also need to ensure the CPaaS system is compatible with any third-party software you’re using.

Browsing a provider’s application gallery will give you a good idea of the platforms they have pre-built integrations for (popular tools include Slack, Asana, Salesforce, Zoho CRM, HubSpot etc.)

The provider should also offer APIs for developers and have a thriving developer community.


Analytics and Reporting 

Analytics and Reporting tools provide insight into common reasons for customer contact, average resolution time, agent activity, and much more.

Key CCaaS monitoring features include:

  • Call recording/call transcription
  • Call monitoring, call barge, call whisper
  • Customizable reports and pre-made reporting templates


Important contact center KPIs and metrics include:

  • First Contact Resolution rates
  • Average Contact Duration, Average Contact Handle Time (per agent and as a whole)
  • Cost per contact
  • CSAT (Customer Satisfaction) rate
  • The ratio of inbound to outbound contact
  • Customer Churn Rate and Customer Retention Rate
  • Contact/Call Abandonment Rate
  • Busiest Contact Dates/Times
  • Channel Use Analysis
