The coronavirus pandemic that swept the world during 2020 caused a number of negative consequences for the world's economies and the general public. In the context of global developments, Croatia could not avoid facing the COVID-19 crisis. Restrictive epidemiological measures were introduced with a very negative impact on the entire economy, including the social sector. This paper analyses the impact of epidemiological measures on the financial sustainability of social services, focusing on the association CeDePe Zagreb. By comparative analysis of two models of financing social services, the paper found that social service providers founded by the Republic of Croatia are in a more favourable position than other providers from the social services network because they are financed based on the overall expenses of the organization. The association CeDePe Zagreb, which uses another financial method conducted by the provided service, in 2020 recorded a decrease in revenues from social services by 32% compared to 2019. Using historical data, the paper analysed the perspective for the development of social services outside the social welfare institutions founded by the Republic of Croatia. It was found that the number of social service providers has been growing steadily over the last ten years. As a precondition for developing the quality of social services it is necessary to establish a unique and transparent financing model for all providers in the social services network, respecting social service standards.
