Juggling multiple communication tools across your remote team? You’re not alone. 48% of businesses now have a hybrid workforce, making efficient communication more critical than ever. 

That’s where Unified Communications as a Service (UCaaS) comes in. 

This single platform consolidates business phone, email, chat, and more, streamlining collaboration and boosting productivity. But with several UCaaS providers on the market, choosing the right one can be daunting. 

This article breaks down the top 8 UCaaS players, comparing features, pricing, customer experience, support, and security to help you find the perfect fit for your business.

What Is Unified Communications?

Unified Communications refers to the integration of various real-time communication services and applications into a single platform or interface. 

When offered as a service (UCaaS), Unified Communications companies consolidate and leverage cloud platforms to integrate workflows and simplify collaboration, driving significant productivity gains and flexibility.

Here are some key benefits UC solutions offer:

• Flexibility to communicate and collaborate from anywhere. Access communication and collaboration capabilities on any device from virtually anywhere through the cloud. Unified communications platforms support flexible and remote work arrangements.
• Ability to scale with cloud-based platforms. Most UC solutions leverage the scalability and flexibility of the cloud. The ease of adding/removing users helps scale capabilities up or down based on evolving needs.
• Cost savings from reduced infrastructure. Unified Communications companies reduce legacy systems needed and provide predictable subscription costs rather than large hardware investments. They simplify administration too.
• Productivity benefits. UC platforms streamline workflows, cut switching between apps, and integrate communication modes. Features like presence and unified messaging save users time. This improves productivity across individuals and teams.

Choosing the Right UC Partner

Choosing the right unified communications platform is key to productivity and growth. Look out for these key things before selecting your ideal solution.

1. Assess your needs

Analyze your existing communication tools (phone, email, video conferencing, etc.) and identify areas for improvement or integration. Also, consider the size, location, and communication habits of your workforce. How many users need access? What devices do they use?

Determining your essential communication channels (voice, video, messaging, etc.) and prioritizing them based on usage helps you budget better. You can define your budget constraints and consider flexible subscription options.

2. Evaluate UC features and functionalities

Prioritize the UCaaS features and functionalities most crucial to your business, considering the total cost of ownership, including hardware, software, and ongoing support.

Look for core features like voice calls, video conferencing, instant messaging, and presence management. Explore additional features like file sharing, screen sharing, call recording, and integrations with other applications, if you need them.

Make sure to choose a provider that can scale with your growing needs and accommodate future additions.

3. Research potential providers

Check for the provider’s experience, market share, and customer reviews. Verifying their security protocols and compliance with relevant industry regulations lets you make an informed decision.

Your provider should also have proven customer support availability, response times, and service level agreements (SLAs).

Next, compare pricing plans, features included, and contract terms from different providers.

4. Request demos and trials

Many providers offer free trials or demos. Use these opportunities to test the platform’s usability, performance, and compatibility with your systems. Don’t forget to engage your team in the evaluation process to gather feedback and ensure user adoption.
