You must have a valid purchase order in order to supply goods, services, and/or works to Schiphol Group. This purchase order contains a description of the goods, services, and/or works to be supplied, the quantity and price, the delivery date, and the applicable terms and conditions. A purchase order constitutes the award of an engagement by Schiphol Group. Please note that unless you have a purchase order, your engagement has not yet been formally confirmed and you cannot begin performing the work.
You will also need the purchase order number to be able to invoice us. Invoices that do not include a purchase order number will not be paid. In addition, unless expressly agreed otherwise, invoices may be sent only after a full or partial delivery has been made and this delivery has been approved.
