    What is an open source CRM?

    What sets open source CRMs apart from proprietary solutions is that its source code is publicly available. Developers and users can access, modify, and distribute the software freely. 

    The concept of open source CRMs can be traced back to the 1990s and early 2000s when open source software started gaining popularity. The rise of open source CRMs was driven by a growing demand for customizable and cost-effective solutions to manage customer relationships and the increasing awareness of the benefits of open source software.

    Which software is right for your business?

    Advantages of open source code

    For businesses of every size, there are myriad advantages to opting for open source CRM solutions. 

    Businesses can tailor the CRM to their specific needs as they have access to the source code. This allows for more flexibility in meeting unique requirements. 

    Open source CRMs are also generally more affordable than proprietary alternatives. There are no licensing fees and users can benefit from the contributions of a large community of developers. Open source projects offer the benefit of a robust development community, resulting in a strong and reliable CRM platform. 

    Advantages of proprietary software

    While open source CRMs offer numerous benefits, there are some advantages to using proprietary CRM solutions. Each business is unique and must find what works best on an individual basis. 

    Proprietary CRM vendors can provide dedicated customer support, including technical assistance and troubleshooting. Community support is available with open source CRMs but can be slow and less efficient than assistance from established software vendors. 

    Proprietary CRMs also come with regularly scheduled updates and upgrades. Regular updates promise quick bug fixes and enhanced security — crucial elements for businesses that lack the in-house technical expertise to manage software updates. Businesses could arguably use more resources on handling updates and integrations than would be used with a monthly subscription for proprietary software. 

    Many essential features and tools are readily available with proprietary CRMs. These platforms are specifically designed to cater to individual business needs. These features can save businesses a significant amount of time in customization and configuration.
