FAQ about the general purchase order, invoice and payment process

For outstandign invoices and invoice questions, please contact the Invoicing department via this form.

You can approach the PO requestor/contactperson of the PO. It is always a Gasunie employee.

Provided the invoice has gone through the entire approval process. We use our standard payment term of 30 days, unless otherwise agreed.

This is only possible if you have entered the invoice directly into Ariba SLP.

The invoices submitted by e-mail usually have a longer lead time than submission via the SBN. These invoices cannot be tracked.

PO failed: then the PO does not arrive correctly at your specified PO sharing e-mail address.
Partially invoiced: you can invoice the rest value of the PO. The rest value becomes visible as soon as you select the PO.

Invoice sent: the invoice has been submitted to Gasunie.
Invoice rejected: click on the invoice, go to the 'history', the reason for rejection will be mentioned in the history.
Invoice approved: the invoice has passed the approval process and is ready for payment. Payment date is invoice date (Ariba entry) + 30 calendar days.
Invoice paid: invoice has been paid (the payment date is available in the history tab within the invoice).

On your SBN account, it is possible that you can only submit an invoice if the VAT/BTW line is added. Be sure to add tax details to the line and set it to 21% or any other, only then will your invoice be accepted. For a number of suppliers, this is a new way of submitting invoices. If it is not possible to submit an invoice on a 46-PO number or any other new PO number, please contact the Procurement Desk.

Invoices can be submitted through SBN, please watch out for POs starting with, among other things, 46- numbers from the new Gasunie account with the name 'Nederlandse Gasunie N.V.' The old 521- PO numbers are still available but can no longer be invoiced. If you don't see the new orders, check the trade relationship. You can see here how to check whether the trade relationship has been successfully established.
