Running a business on an international scale requires not only a substantial body of knowledge but also the ability to apply it in practice. That is why our textbook, with a vast collection of practical examples, discusses a wide variety of pertinent issues connected with business operations in international markets, from international market analysis, drafting business plans, concluding business transactions and the insurance of goods through to customs clearance procedures and professional etiquette. We also explain the specificity of doing business online. The book is addressed primarily to students of courses in economics and management. We hope it will also make interesting reading for entrepreneurs and people indirectly involved in international business, who work in its immediate environment in banks, chambers of commerce and consulting companies and those who have dealings with public administration at different levels in foreign countries. This book has been published under the project „The creation of new interdisciplinary curricula in the field of economics of environmental protection (in Polish and English) at the University of Łódź” supported by a grant from Norway through the Norway Grants and co-financed by the Polish funds.
