Open Source CRM Software: An Overview

Customer relationship management (CRM) software is important for managing contacts, accounts, leads and clients for any business. Traditionally, businesses had to invest thousands of dollars each year on expensive proprietary CRM solutions. However, in the past decade, open source CRM software has emerged as a low-cost and highly customizable alternative.

What is Open Source CRM?

Open source refers to software where the source code is made available to the public so that anyone can modify or customize it. Open source CRM software is distributed free of charge or for a nominal one-time fee. The key advantages of open source CRM include:

– Lower Total Cost of Ownership: There are no recurring licensing fees. Businesses only need to pay for customizations and support.

– Customizability: By accessing the source code, businesses can modify and customize the CRM to exactly suit their requirements rather than being limited by vendor restrictions.

– Flexibility: Open source CRM Software offer more flexibility to integrate with other systems and scale as the business expands compared to proprietary solutions.
