Businesses always want to provide the best customer service possible. To do that, they need the best customer service software to decrease response time and resolve customer inquiries effectively.

However, organizations sometimes face challenges while acquiring and setting up customer service systems. They want a tool tailored to their needs that supports various customer service channels, and that allows them to control their own data.

These criteria is met with open source customer service software. Solutions operating on open source technology offer unique benefits to businesses looking for high level of flexibility and security.

Read on to find out what are the best open source solutions for customer service.

What is an open source customer service software?

Open source customer service software is a solution that enables organizations to effectively manage customer inquiries and is created under an open source license. Such license categorizes the use of the software at hand, but being open sourced generally means that the software code is publicly available and free to use (to some extent).

This leads to engagement from community members that gladly participate in open source projects. In turn, the software is made more secure, feature-rich, and easily scalable.

Due to the steep price of leading market solutions, organizations are turning to open source alternatives to Zendesk and similar software.
