This paper is focused on CRM (Customer Relationship Management) systems and their support for international contacts. The method solution is based on a literature review and monitoring of CRM systems for multilingual features and other localization functions. Choosing the optimal CRM is difficult among hundreds of CRM systems. CRM systems range from opulent solutions to small tools and there is a lot of diversity in the implemented solutions. Only a few CRM systems offer a comprehensive background for the global market, such as Dynamic CRM, HubSpot, OnlyOffice, Oracle NetSuite, SAP CRM, or Zoho CRM. Many others focus on local markets or prefer English as the default language. For a detailed evaluation of CRM systems, it is recommended to use Saaty’s method.
