As part of the procurement costs, order processing costs are the direct costs of the procurement process. They are made up of purchasing costs, disposition costs and access costs. Purchasing costs are the direct costs of the purchase process. This can be the cost of own services (e.g. the cost of preparing decisions through inquiries and reviews of offers) or third-party services (commissions and brokerage fees). The disposition costs include, for example, the costs for order monitoring. Access costs are, for example, costs for goods inspection, invoice verification and payment.
Bestellabwicklungskosten können unabhängig (bestellfixe Kosten) oder abhängig von der Beschaffungsmenge sein. Die fixen Bestandteile der Bestellabwicklungskosten sind in Optimierungsmodellen zur Order quantity planning zu berücksichtigen.
