International trade and globalization have created a demand for a legal framework that governs international business-to-business contracts on the sale of goods. This led to the introduction of the 1980 United Nations Convention on Contracts for the International Sale of Goods (CISG) of 11 April 1980, BGBl 96/1988 which provides such framework. By the end of 2015 the CISG had been adopted by 84 states. In application of the CISG, the incorporation of standard terms to a contract is a significant aspect that often leads to dispute. The present thesis deals with the incorporation of standard terms under the CISG. It particularly focusses on the incorporation of terms by means of electronic communications. Starting with the provisions on incorporation found within the CISG, the thesis will then deal with the respective requirements to incorporate standard terms successfully. With regard to this, there will be an emphasis on the relevant prerequisites in use of electronic communications. Since offer and acceptance do not always correspond with regard to the standard terms, the practically relevant “battle of forms” will be addressed in the last part of this thesis.
