The subject of this paper is the role of communication skills and ethics in business negotiation in the production and sale of sheet metal. Today, companies often seek to strengthen their business capacity and expand their business to foreign markets. In such processes, they must involve other parties with whom it is not always easy to reach agreements. Often, just finding new business partners requires longer business talks or negotiations. Companies also negotiate the purchase of materials, sales and execution of large orders that have room to change items (prices, discounts, etc.). Such negotiations may require knowledge of other languages and cultures. Therefore, we want to find out how much companies are actually aware of the importance of preparation for business negotiations and how much they take into account various issues in the negotiations and its parts. It is important to find out how much companies pay attention to communication skills during negotiations, or how much they consider them important. The importance of negotiation in the business environment is proven by numerous professional researches and works in which this topic is described in detail with the most important elements, stages and problems that may arise. Each negotiation will consist of communication, verbal, nonverbal and paraverbal. While many would say that the importance of verbal communication is much greater, nonverbal communication leads to much greater importance during negotiations. However, it is important to note that these three communications must together form one whole, that is, no communication should be left out. Today, there are various norms of behavior and codes of ethics, but in the business world, ways can still be found to circumvent moral and ethical norms. In most cases, companies will not recognize unethical practices but their actions may ultimately cost them market positioning. All of the above is important for any company that wants to maintain its profitability and follow European and world trends. In order to show the importance of preparation for negotiations, communication skills and business ethics, a survey was conducted in three companies engaged in the production and sale of sheet metal, namely Modeco d.o.o. Lim-Mont d.o.o. and Đuro Đaković Termoenergetska postrojenja d.o.o.
