How to work with us

In this toolbox, you will find useful information and documents to help you to meet your commitments to the Proximus Group when delivering products or providing services.


SAP Ariba

We are pleased to inform you that Proximus is transforming the way we interact with you as of March 2019.

We will launch SAP Ariba, which will replace our current supplier relationship tools. You can find more information on the Ariba tool, its features and the benefits below.


We are transforming our way of sourcing and management of contractors, which will improve the speed, simplicity, transparency and identification of qualified resources.

Currently we are implementing the new process to manage the E2E contractor lifecycle within Proximus.


As from November 21st 2016, the agreements between Procurement and the Suppliers will be signed in a secured electronic way, using the ADOBE Sign platform.

Read the short explanatory manual or consult your Buyer at Proximus.

Contracts & orders

These documents serve as basis for cooperation and can be changed or adapted to fit your business.
They do not by any means represent any commitment on the part of Proximus.


Delivery conditions

The purpose of this document is to provide you the instructions you require to prepare your deliveries and to deliver the goods in correct way. These guidelines, called delivery requirements, set out the practical delivery procedure, the formal specifications for the delivery documents and the manner in which the goods should be conditioned and identified.

To ensure that the delivery process runs smoothly, flawlessly and safely, these delivery requirements must be strictly complied with. This is in the interests of both Proximus and the supplier. Goods delivered in the correct way will be received correctly, which in turn means that your invoices can be paid correctly - and on time. The Proximus employees in charge of receiving goods will check if your deliveries meet the delivery requirements. In case of a non-compliance, the receiving process and our ability to process goods will be slowed down.

Any delivery that does not conform to these requirements may be refused which will have an impact on our evaluation of the service you provide.

Any material must be delivered packaged in accordance with the applicable regulations. The packaging must provide sufficient protection to withstand reasonable dry, unheated environmental conditions and normal handling during loading, unloading, storage and forwarding.

The type, the manufacturing number, the manufacturing date (or week) and the Proximus stock number must be indicated clearly on each unit, including on any prototypes. For material that exists in different versions (e.g. software version in an EPROM), each version must be clearly identifiable, i.e. it must feature a new identification number, version number or tag on the EPROM. If requested by Proximus, the supplier should include bar codes (EAN 13) on the packaging.

The supplier must comply with all the relevant European Community Directives on packaging.

Deliveries of goods to Proximus may need to be made to several locations. All purchase orders and contracts state where the deliveries should be made.

Proximus Distribution Center (PDC) - Courcelles

The Proximus Group's central warehouse is operational since September 2011. The site is called the Proximus Distribution Center (PDC) and is located at rue de Liège 70 in 6180 Courcelles, about 60 km to the south of Brussels.

Proximus Outside Infrastructure Distribution Center (OIDC) - Flawinne

For some years now, Proximus has had a central warehouse for storing copper, fiber optic cables and other related voluminous products. This site is called the Proximus Outside Infrastructure Distribution Center Flawinne and is located in the industrial area of Flawinne, about five kilometers south of Namur. This location, run entirely by Proximus staff, also serves as a distribution center.

Cabling works & installations

Specific works are required to extend and maintain the Proximus telecommunications network. Given the complexity of the technology, only qualified contractors are eligible to perform these works.

Procurement and the Proximus technical teams will make the Proximus safety instructions that apply to works available to contractors.

The documents serve as a basis for cooperation and all but the safety instructions can be changed or adapted to fit your business. They do not by any means represent any commitment on the part of Proximus.

The documents concerning Health and Safety regulations are not available in English. For more information, please consult the French or Dutch versions.
