Tools for suppliers

This section summarises the tools we use to ensure optimum collaboration. These are resources and platforms that support sourcing and invoicing.

General Terms and Conditions of Purchase:

Access to Ariba Sourcing:
This is the environment which Ariba Sourcing makes available to NS (secure connection) for its procurement activities.
You can only log on in this environment after NS has issued a user name and password to you. We have to link your organisation to the tender beforehand.

The log-on environment can be found here:

The tender platform:
Public departments (commissioning authorities) publish national or European tenders on TenderNed. NS also publishes tenders on this website. Contractors can also view information about the proposed contracts via this website.

Tenders Electronic Daily (TED):
This website is the Supplement to the Official Journal of the European Union. All European Union government contracts that exceed a specific value are published here.

Dun & Bradstreet:
You require a D-U-N-S number to do business with NS. If you do not yet have this number, you can request it via Dun & Bradstreet’s website.

Digitally signing of documents
As a modern organisation NS Procurement has decided to switch to digitally signing documents (such as contracts) instead of physically signing them. This makes the signature process safer, faster, and more environmentally friendly.

Safer, because physical documents can’t end up lost, or in the hands of the wrong person. Faster, because the printing and scanning of documents now becomes obsolete. And better for the environment because the use of paper and ink isn’t required.
