Every large or small enterprise needs to have financial liquidity and to be able to generate profits to develop . It is not important in which sector it operates, whether it is a private or public one, but profits and safety are two elements every enterprise is not able to function without . The low performance of these two measures can cause a number of difficulties for managers . To avoid this, leading companies, especially the smallest ones, should optimize the trade credit management policy . Most often, SMEs' (small and medium-sized enterprises) owners try to work together as part of a group purchasing organization, which positively affects trade credit management . The aim of the paper is to present the trade credit management strategy in Polish group purchasing organizations during the COVID-19 pandemic . The study uses data on the construction sector because it is one of the most important segments of the Polish economy, which is financed to a large extent with trade credit . The paper indicates the mechanisms whose applications allowed SMEs operating in purchasing groups to change trade credit management strategies in such a way that these units could operate calmly and safely in the market . These changes could be observed in purchasing goods with a large reserve, strictly controlling all receivables, switching to cash sales or limiting sales on long-term trade credit . The analysis showed that enterprises changed trade credit management strategies from moderately conservative to highly conservative.
