In this thesis, it is explained why it is important to manage business documentation, since documents follow different business processes and they have to be available so employers could do their jobs efficiently. In order to realize the importance of business documentation, it is important to understand the terms „foreign trade exchange“ and „foreign trade business“, and who the participants in the exchange process are. Documents that follow foreign trade exchange operations are very important and it is important to manage the business documentation correctly, and especially to apply the modern way of archiving and digitalization of documents. There is a variety of papers, i.e. documents in the foreign trade exchange and in this thesis the classification of business documentation is shown, whereas commercial documents as papers that contain specific information on goods are explained in more detail and for some of them there are annexes that show which crucial parts they have to contain. One of the most important commercial documents are the invoices, and this thesis explains what commercial invoices and other types of invoices are, followed by other documents that are frequently used with invoices, such as specification of goods and packing list. Knowledge that is stored in the documents of big business systems is precious and those who manage to introduce systematization, which implies detailed analysis of the flow and life cycle of documents, defining their position, as well as the role of every employee towards the documents, in their own concept of business manage to achieve the necessary sorting of documents by type, detecting idling in business processes, as well as understanding of legal regulations for archiving and they establish, as their final goal, a more efficient and fully viewed work.
