The idea of the CRM-type systems is to facilitate and coordinate all activities undertaken when dealing with clients, the ultimate objective being to increase the success of sales and improvement of the post-sales customer service. They manage the processes of communication with clients (phone conversations, email, meetings, letters, faxes, etc.). They also manage and coordinate the activities of the separate dealers so that they work better in a team on specific projects. An important point is that systems of this type include all files with contracts, offers, protocols, etc. in a unified card index for each client. They also manage marketing campaigns. The CRM systems also monitor and manage the duration of events in order that the client pays for this time or in order to optimize the number of employees necessary for the performance of the tasks.
