The purpose of this work study is to develop an information system for the circulation of alternative currency within a closed economic community. An organization that unites people with disabilities is a such community. Based on the analysis of its activities, a matrix of mutual exchange of services and goods between participants was modeled. a network graph of participants' interaction was visualized with the UCINET software. Also, the product lifecycle, use-case diagram and class diagrams, as well as business processes of work in the developed payment system were modeled.
