Are you searching for a service provider or supplier? Especially in the construction sector, but also in many other industries, clients put their projects out to tender in order to find the best supplier. It is then the responsibility of the company to submit a professional bid by the relevant deadline. Tender databases provide a quick overview of the invitations to tender issued across Germany and even internationally. Companies that regularly use these databases have many opportunities to benefit from RAL Gütezeichen (Quality Marks).
