Not been invited to bid

My vendor registration application with UNGM was successful but I have not been invited to bid. Why is this?

We want to emphasize that successful registration with the UNGM should not be equated with business opportunities. It is your responsibility to find out about current WTO projects by visiting the UNGM website and looking at WTO procurement notices. Therefore, we advise companies to regularly visit the UNGM website.


How does the WTO pay contactors?

WTO’s normal terms are payment by bank transfer within thirty days of receipt of an invoice in good order. Payments can be made by instalments but no payment can be made as long as the delivery of contracted goods or services has not begun. Invoices are to be sent to the address indicated in the purchase order. Invoices shall only be paid to the contractor. The contractor may also be required to provide evidence that the bank account to which it requests the transfer to be made is actually the contractor's bank account.


I have heard that WTO purchases are exempt from taxes and duties. Is this true?

Under Article 9 of the Headquarters Agreement concluded between the WTO and the Swiss Confederation, the WTO is exempt from indirect federal, cantonal and communal taxes in Switzerland and, in particular, from value-added tax (VAT) with respect to all purchases of goods for its official use and all services provided for its official use.

I want to come to the WTO and present my company's products or services. Whom I should contact?
