Vtiger
Vtiger is an open source CRM software program that helps companies keep up with clients in a way that makes sense. Client retention has never been more important, and keeping in touch with those clients can be a challenge for those who don't use technology. Vtiger figured out a way to use open source technology to bring companies closer to the people they serve. Importantly, this software is intuitive and allows even the technologically challenged to stay on top of things. The software allows companies to input and maintain the relevant data about each customer. This way, companies can know when a person bought, how satisfied they were, and what has been done in the meantime to keep in touch. It's the sort of software that leads to repeat sales and allows companies to capitalize on the good service they have provided to their customers in the past.
