How to choose the right call center software for your business

With the right call center software tool that provides all the functionalities you require, you can scale your support, sales, and marketing efforts. Take a look at the considerations to keep in mind when purchasing call center software:

  • Check the deployment options available: Call center software vendors offer on-premise, hosted, and cloud-based options. On-premise and hosted tools provide customizable features but could be expensive and require installation and configuration support. Cloud-based options are generally cheaper and can be set up within a short time.
  • Integrations with other software: An ideal call center software should integrate with your CRM software, marketing tools, social media business accounts, websites, and help desk software. Integrations with other software gives you a bird’s eye view of your business’s efficiency and productivity.
  • Pick a tool with multichannel support: Your customers will not always default to calling you. They might email, chat, or get in touch through social media channels. If your software is not equipped with multichannel support, then communication gets siloed, and your customers will end up explaining their issue again and again.

Common questions to ask while selecting free call center software

Here are some questions to ask call center software vendors before making the final decision:

What are the limitations of free software?

Free software comes with limited features and your call center requirements could be extensive. Before purchasing, ensure all your business’s requirements are fulfilled, otherwise, you might end up providing low-quality services to your customers.

Does the vendor offer technical support?

Free users often get limited support options, while paid users receive priority and emergency support. Therefore, check all the support options available and the turnaround time of the vendor’s support team.

Does the software offer an analytics report?

Your call center software should be able to provide analytics reports for call quality, call flow, and agent productivity to identify what needs improvement.

How did we choose these products? We didn’t—you did.

To find your ideal software match, you need information you can trust—so you can save time, stay on budget, and focus more energy on growing your business. It’s why we vet and verify all our user reviews and recommend only the tools endorsed by people such as you.

In other words, our product recommendations are never bought or sold, or based on the opinion of a single individual—they’re chosen by your peers, reflecting the views and experiences of our independent base of software reviewers.

To be considered for this list, products have to:

  1. Have at least 20 unique product reviews published on Capterra within the past two years, with an average rating of 3.0 or higher. We selected the five products with the highest ratings to feature in this article.
  2. Offer a free, standalone version of the software (not a trial version of the software where you must purchase a product after a limited amount of time).
  3. Meet our call center software market definition: “Call Center software helps organizations manage inbound and outbound communications with customers and prospects across a variety of channels (e.g., voice, live chat, social media).”

Note: The content in this piece that provides opinions and points of view expressed by users does not represent the views of Capterra.

“Best functionality” tool is identified based on the highest user-ratings for functionality that a vendor received based on publicly available reviews.  
“Most affordable” tool is identified based on the lowest pricing a vendor offered on their website in terms of cost to upgrade on October 11, 2021.
