The aim of the article is to suggest a monitoring tool for a business model to assess performance and meet sustainable development goals and indicators for the sea commercial ports. According to the 2030 Sustainable Development Agenda, building resilient infrastructure, promoting inclusive and sustainable industrialization and fostering innovation is one of the seventeen goals set forward. We assume that added value is the key aim of any business model creation, while business model itself is recommended to be based on multidimensional innovation and complementary assets of business.The multidimensional innovations include: market innovation, product innovation and process innovation. The introduction part here presents the description of the business model development roadmap. For the specific case of a trade port case the business model rests on four blocks: the system for added value generation, value suggestion, clients and financial model. The complementary assets’ list is presented for such a sea commercial port. Qualitative and quantitative indicators of the sea trade port business model performance are tracked down. Business model sustainable development for a sea commercial port is described. Value added is considered as the indicator of sustainable development on both micro- and macrolevels.
