Best Open Source CRM of 2023

What is a CRM

A CRM, or customer relationship management, is a system or software that helps businesses manage and analyze customer interactions and data throughout the customer lifecycle. This includes storing information about customers and their interactions, such as sales and marketing activities, customer service inquiries, and purchase history. A CRM system aims to improve customer relationships, increase sales and customer retention, and streamline business processes. Some common features of a CRM system include contact management, sales management, marketing automation, and customer service and support. CRM can be cloud-based or on-premises and can be open-source or proprietary.

What is open-source CRM?

Open-source CRM, or open-source customer relationship management, refers to CRM software freely available for anyone to use, modify, and distribute. Unlike proprietary CRM software, the source code of open-source CRM is publicly available, which allows users to customize the software to fit their specific needs.

Open-source CRM is typically developed and maintained by a community of developers and users who contribute to the project by fixing bugs, adding new features, and providing support. Some popular open-source CRM options include vtiger CRM, SuiteCRM, and Odoo.

Businesses of all sizes can use open-source CRM software, which is often a cost-effective option for small and medium-sized companies that do not have the budget for expensive proprietary CRM software. Additionally, it gives more flexibility and control to the organization using it.

Best Open Source CRM

Open-source CRM is an essential tool in any business. It helps keep track of customer information and interactions and makes it easier to communicate with customers. Open-source software is free to download, customize, and use for your business. However, not all open-source CRM systems are created equal! Therefore, it would be best to consider which features matter most to your company before deciding which system best fits you. This article will cover six top open-source CRM systems: SuiteCRM, Vtiger, OroCRM, Zurmo, Fat Free CRM (FFC), and Sprott Technologies (SPT). By the end of this article, you'll have a good idea about which one might be best suited for your needs!

The installation process is simple and straightforward. You can download SuiteCRM from our website, or you can use git to clone the codebase. Once you've got your copy of SuiteCRM on your computer, you'll need to run composer install to install all dependencies (this may take some time). Next, create an empty database using phpmyadmin or MySQL Workbench; make sure that all permissions are set correctly for SuiteCRM's root user account before proceeding with this step!

Once your database has been set up, open up config/configuration.yml in a text editor and change any settings as necessary (we recommend looking through each section at least briefly). Don't forget about first_time_setup if you haven't done so already--it will guide you through initial setup tasks such as creating users and assigning them roles based on their email addresses.

Once everything looks good in config/, run ./bin/suitecrm install --dev which will complete the installation process by creating new migrations tables within MySQL and setting up development mode environment variables required by Sublime Text 3 plugin

Single Sign On (SSO)

Single sign on (SSO) is a way of allowing users to use multiple applications without having to log in separately. It uses a single set of credentials, which can be either an administrator account or the user's email address and password. SSO is used by many companies, especially large ones like Google and Facebook, who want their users to access all of their services with just one set of credentials.

In SuiteCRM, we have implemented an SSO system that uses SAML 2.0 as its authentication protocol. This allows you as an administrator or developer to create users in SuiteCRM using LDAP directories such as Active Directory or OpenLDAP--and then those same users will be able to log into other systems that support SAML 2.0 (such as Gmail).
