Costing software is used by companies to determine unit costs, costs of a service, production costs and the net or gross sales price in order to achieve cost transparency, to calculate products or services and above all to assess their own competitiveness. For a more precise calculation, data from operational cost accounting is required. Costing software includes, for example, quotation and order processing, cost and profit controlling, product costing, preliminary and final costing, warehouse management, ordering and purchasing. Almost every area of controlling is based on costing procedures.
