# PostIncomingInvoiceCommandRequestInput

> Posts an incoming invoice. Posting makes the invoice binding: its supplier, address, line items and additional costs are locked, and the purchase prices of the delivered items (average and last purchase price, value of the goods receipts) are updated from the invoice prices and the additional costs that count towards the purchase price. Posting cannot be undone. Per item of a purchase order, the posted invoices must not contain more than was delivered; line items of fulfilment-network (FBA) purchases and of dropshipping purchase orders are not checked. - Request
