Welcome to the Supplier Info Portal for the Customers of Siemens GBS

Siemens Introduction

This supplier info portal is managed by Siemens Global Business Services to support the P2P process of its business partners.

Our goal in supply chain management is to create added value for all our customers. The pursuit of innovation, productivity, quality and availability always forms the basis of our actions. With this in mind, we have set ourselves to digitize and optimize our business processes across the entire supply chain. Together with our suppliers, we want to lead the way, exploit the potential of digital transformation and benefit all parties. In doing so, we act with foresight and with a sense of responsibility. 

For the transition to electronic business processes, we rely on SupplyOn, a partner with many years of experience and expertise in this sector. 

The new Purchase-to-Pay (P2P) Process via SupplyOn

Handling business processes online has become a daily routine for all of us in many areas of our private and business lives today.

Siemens handles the entire P2P process electronically via SupplyOn: from the order, including order confirmation, through delivery schedules and advanced shipping notifications (ASN) up to the invoice.

In this 2-minute video we offer you a summary of what to expect as a supplier from this change. See for yourself the advantages of switching to the electronic ordering and invoicing process with Siemens and SupplyOn:

The Right Connection and Message Format for Every Company

SupplyOn offers different types of connections. Which one is right for your company depends on your company size, your order volume and the existing IT infrastructure. You can either process your orders, order confirmations, invoices etc. via SupplyOn's web front-end (Supply Chain Collaboration) or you can automatically exchange the data with a direct EDI connection to your internal ERP systems.

Connection via SupplyOn web front-end (WebEDI)

To work via SupplyOn's web front-end (Supply Chain Collaboration) you only need a computer or a tablet, a browser and Internet access. You receive your customers' EDI messages through the SupplyOn web interface and you can also send your data back via web browser. Your customer receives them as EDI messages.

All you have to do is register your company with SupplyOn and you can use SupplyOn Supply Chain Collaboration for all your locations. Your company administrator can then create as many users as you wish.

Technical Requirements 


EDI Connection with your customer

Are you interested in an EDI connection between your company and your customer which allows you to exchange data directly from your ERP system?

In our EDI Info-Portal we have summarized all the necessary information about the EDI connection, which steps will follow next, which message formats are allowed and a lot more information. Please inform yourself in advance. If you have any further questions, please contact our EDI team at SupplyOn:  integration-service@supplyon.com

Important note: Before you order an EDI connection, you must register your company for SupplyOn Supply Chain Collaboration.

Further Channels

CSV or XML up- and download as well as e-mail PDF transfer (for invoices only) are available as additional channels for you.  

CSV or XML Up- and Download

As additional channels to import data from or extract data onto the platform, SupplyOn supports the up- and download of CSV or XML files. The CSV and XML file must only meet certain content and format requirements. You can find out more about this in the CSV Portal  (invoice) as well as the file format descriptions for Delivery Instruction, Order, Order Response and Advanced Shipping Notification.

Create PDF and send it by e-mail

Another way to transfer data is to create your invoices and financial documents in your system as PDF documents and send them by e-mail. The prerequisite is that Siemens has activated your company for this service and that the PDF documents meet a few requirements in terms of content and form. You can find out more about this in our PDF Information Page.

This is the process to register your company with SupplyOn

Please note: When you register your company, you are assigned the role of company administrator. You can transfer this role to someone else at a later date.

SupplyOn Processes - All in One System

In the future, Siemens will handle the entire purchase-to-pay process (P2P) with selected suppliers electronically via SupplyOn - from the orders including order confirmations, through delivery instructions and advanced shipping notifications (ASN) up to the invoices. For suppliers participating in the Document Management System (DMS), all accompanying documents such as standards, parts lists and drawings will also be made available via SupplyOn. This makes ordering by fax, e-mail and telephone, which causes process interruptions, involves a high administrative effort and is error-prone and non-transparent, a thing of the past.

Please note: Detailed information and Siemens-specific supplier guides for the individual processes can be found in the pop-ups below. The videos within the pop-ups provide you with an introduction to the general SupplyOn processes.
