What is an open source CRM system?

An open source app means its source code is publicly available. This is the code that makes the program run. This source code may be modified and shared by users according to their needs. The idea is that, if any and all developers can tweak the program, the app will become more useful over time.

Developers get together on Github or other platforms to fix bugs. They add features or change existing ones. Companies hire out developers to modify the open source CRM tool of their choice. This is how they get a platform that meets their specific needs. 

Do you know what is CRM? If so, then feel free to continue reading. If not, we advise you to familiarize yourself with the basics first.

Open source CRM systems usually run on Linux. This is as opposed to the usual Mac/Windows support. They use freely available software like Apache web server and PHP. Any software that operates under an Open Source Initiative and holds an OSI-compliant license can be integrated into a CRM platform. 

Open source customer relationship management offers all the useful features of a proprietary CRM. These include customer support, pipeline management, market automation, and contact management. However, there are significant differences between the two types to consider. We explain it all here. 

 

Open CRM source code systems vs proprietary software

Proprietary software is a closed system. It's a product locked up in a black box. You download it for free or buy a subscription. Then you set it up for your needs. There is no assembly required. You can skip hiring in-house developers. This is a 'full stack' category of CRM. It's designed for the big picture. They can cover basic needs across the board, right out of the box.

An open source customer management system's source code is open. It's available to the public for use and modification. You can take the product and tweak things here and there towards your specific needs. In most cases, open source code is already well-developed. Customization solutions have been streamlined for speed and ease.

Small and medium-sized businesses go open source. Others choose closed-source, proprietary software. Both types do sales, service, marketing, project management, and every other CRM thing you can imagine. They usually come with mobile apps that let you work on-the-go.

Qualitatively speaking, there's not a massive difference between the two. The choice is really all down to what kind of CRM applications you need, and how much time you're willing to invest in getting your system up and running.

 

Open Source CRM overview

 

The advantages of open source CRM software

There is a clear appeal in the open source movement that surrounds CRM. With its sense of community and freedom to innovate, contributing to open source can feel like you're producing something original.

Others might find open source software development to be time-consuming. It might be a distraction from your primary business.

One advantage of open source is that these CRM systems have more robust integrations and plugins. You can build the exact integration you want without any vendor restrictions. If you're concerned about flexibility and scalability over time, open source has the advantage.

Another very pragmatic reason for using open source tools is its cost. They're free or affordably priced. They are less likely to have time-based commitments to software licenses.

If you signed up for a year with a proprietary CRM but decided it wasn't right some months in, you'd likely still pay for the year. That wouldn't happen with most open source tools.
 

Out of the box vs ready-to-go

While both kinds of software are functional out of the box, proprietary software is ready-to-go after the initial set-up. Open source business tools are usually going to require developer hours. Open source CRM systems also require a bigger implementation plan to make them worth the time invested.

If you choose an open source platform, it's important to make sure it has a strong, active community of developers. Updates, bug fixes, and the like all have to be taken care of by the developer community surrounding the platform.
