Best Free and Open Source CRM Software

Best Free and Open Source CRM Software: Customer relationship management (CRM) is a business strategy for managing and understanding clients and sales prospects to help enhance customer satisfaction and thus increase profit and reduce operational costs. CRM software is needed to collect the correct information about a company's customers and arrange that information for proper analysis and action. It is a tool for organizing, automating, and synchronize business processes for sales activities, marketing, customer service, and technical support. The information gathered by a CMS software needs to be kept up-to-date, accessible to employees, and provide the knowledge for employees to convert that data into products better matched to customers' needs.
