costdata GmbH is a German consulting and software company headquartered in Cologne (Köln) that specialises in product cost calculation, should-costing, and procurement benchmarking. The firm has built and maintained a worldwide market data set for more than 25 years, covering benchmark data on wages and salaries, workplace costs, machinery, material prices, location factors, and overhead cost structures. costdata's offering combines this database with software modules used by cost engineers and procurement teams to estimate, optimise, and analyse product costs. Since July 2021, costdata has been an official SAP partner, and three of its solutions are integrated with SAP Product Lifecycle Costing (PLC). One solution embeds the should-costing capability inside the SAP PLC App, while the costdata estimation module enables rapid cost estimates using costdata's reference data. SAP lists costdata solutions under both supply chain and spend management partner catalogues, including Market Data offerings available in cloud and on-premise deployments. The company is positioned as an SAP Registered Partner in the ISV category, providing data-driven add-ons rather than full ERP implementation services, and its consulting team supports customers with should-costing calculations, optimisation, analysis, and training around cost engineering practice.
