Abstract
The article presents the CRM (Customer Relationship Management) philosophy. The principles of building the CRM strategy, enabling building and strengthening ties with the client (including ensuring its safety in relationship with a company), thanks to which the company can expect continuous sales, have been presented. Exemplary tools used in CRM (such as: call centre, contact centre, key account management) are listed and described. An attempt has been made to assess the cost-effectiveness of implementing the CRM philosophy in the enterprise based on the SWOT analysis. The strengths, weaknesses, opportunities and threats of such an undertaking were analysed, and the results were presented in the summary and final conclusions.
