Best Free and Open Source CRM Software to Scale Up Your Business

The 5 best free and open source CRM software that help you to manage your customer relations efficiently. An effective CRM software also enhances the level of customer satisfaction.

Acquiring new customers is important to scale up a business, but retaining the existing customers is equally important if you have a long-term vision. Maintaining a good relationship with customers attaches them emotionally with your business and they take pride in referring your products and services to others.

However, as a business scales up, it becomes cumbersome to maintain a healthy relationship with customers. It involves a lot of things including offering support and responding to their queries within the promised timeline. If not done properly, this can result in customer dissatisfaction and negative word of mouth publicity. If you have a business that is scaling up, you might very well relate to this scenario.

An effective CRM software can be of great help here. A CRM software is basically a combination of multiple tools that can be used simultaneously to offer various kinds of support to your existing customers and future prospects systematically. In case you are not finding yourself ready to invest money in a paid software, there are some free and open source CRM software available to start with.
