Bitrix24 gives a platform to sort out and track interaction with potential or existing customers, partners, agents, and different contacts. Bitrix24’s CRM creates a contact base where the interaction and the history of contacts are arranged and stored. All new events (phone calls, messages, meetings) connected with a contact or company are easily logged and further interaction can be planned, including by using integrated tasks. Bitrix24 is a free CRM system available both on the web and as self-hosted software that can be installed on your own server. If you go for this option, you’ll get access to open-source code as well. Bitrix24 is additionally the only free CRM that comes with an integrated call center, so you can make and receive phone calls to/from your CRM as soon as you are registered.
