About

Kostenia helps German businesses and advisers investigate operating costs using financial exports and supporting documents. The web application organizes cost categories, recurring payments and year-on-year changes into a structured review. Findings connect each amount to a calculation, reference source and next verification step. Public calculators cover company broadcasting contributions, leasing factors and payment-card interchange fees. The website includes a product demonstration. Users import existing financial export files and use the resulting evidence to prepare focused reviews of contracts, charges and recurring expenses. Actual savings depend on the documents and case-by-case verification. Kostenia is a German-language product operated by Nelten Public GmbH in Dresden, Germany. Business phone: +49 351 44289997.
