The Internet and digital technologies are changing our world. Diagnosing the gap in digital competences of Polish small and medium-sized enterprises should be the starting point for building recommendations regarding the use of modern information and communication technologies by SMEs. An assessment of the degree to which they use digital solutions against the background of European enterprises can help convince managers that digital competences are the basic determinant of the success of companies, and modern digital solutions simplify and accelerate decision-making and management processes (EDI and ERP systems), allow for more effective business analytics (cloud computing), simplify transactions (e-commerce or e-invoices), allow for building relationships with the company's environment (CRM systems, social media) or facilitate reaching new customers and entering new markets (e-commerce, CRM). The source of problems with implementing the above solutions is the failure of Polish entrepreneurs to notice their usefulness and the deficit of digital competences, especially intermediate ones, in human capital. For the purpose of assessing competencies, the DESI index was used in five main areas: connectivity, human capital, use of the Internet, integration of digital technology, digital public services. In the distinguished areas of digitalization, Poland's position was presented in the context of EU Member States, and then one of its components - "introduction of digital technologies" was analyzed in more detail. The DESI index of digital technology implementation consisted of such components as: electronic information exchange, social media, electronic invoicing, cloud computing, e-commerce. The conclusions concern the degree of digitalization of SMEs in the indicated areas and the reasons for the low position of Polish SMEs in studies analyzing the introduction of digital technologies in enterprises.
