Zoho
Zoho CRM is one of the most popular CRM systems built with the needs of small businesses in mind. It is made by the same team that brought many other online business and productivity applications to the world, like Zoho Mail. The system comes with an online interface that is very easy to understand and use right from the start, so you won't have to waste hours figuring out how everything works or training your team. Instead, you can focus on what is most important: making sales and providing excellent service to your customers. The CRM comes several editions to meet the requirements of any sales team. There is a free version with basic features, as well as four paid versions with more advanced functionality, like sales forecasting, social integration, workflow automation, inventory management, mass email, call center connectivity and plenty of others. You can try the system free for 15 days with no obligation.
