Freshdesk
Freshdesk is CRM software with an emphasis on customer support. Their simple philosophy is that helping you to help your customers creates happy customers, and happy customers, in turn, become repeat customers. It can be more accurately thought of as customer relationship enhancement rather than customer relationship management software. This powerful software brings many tools to bear to make this happen. It offers a ticketing system, so customers have a clear system by which to request support and to know that their needs will be taken care of. It also provides a knowledge base to help them answer any questions they may have and the ability to set up a community forum to ask others for help. Live chat support, phone support and mobile in-app support round out the incredible features of this software that will keep any businesses' customers coming back for more. They have 70,000 users and offer a free trial.
