Siemens Electronic Supplier Integration (ESI+)


Siemens is executing the Vision 2020. A major focus of this strategy is digitalization, across all parts of our business.

The digitalization of the Purchase-to-Pay (P2P) process has the potential to create value for all parties involved. As a result, the Electronic Supplier Integration (ESI+) portfolio of solutions has been introduced to digitize the Supply Chain from purchase orders to invoice. The future is digital and the future of P2P at Siemens is Electronic Supplier Integration (ESI+).

Digitalization is fundamentally transforming the value chain and offers major opportunities for all parties

Going digital!

Automated order processing. Speed. End-to-end visibility.

Manual errors removed. Quality improved. Efficiency.


Digitalization is not just a project - for us, it has become part of our strategy. Within the coming months, we will focus on Electronic Supplier Integration (ESI+) to raise the number of connected suppliers to significantly increase the number of digital transactions.


We are aware that this step may also require changes on your side. We ask you to join forces to capture the potentials for both our companies. Let’s unlock the value of digitalization in your order-to-cash and our purchase-to-pay process from beginning to end! Implementing this initiative will help both our companies to strengthen our business processes in efficiency and performance.


The future is digital – please join us on this path!

The future is now!

We live in a world of constant change, the only way to manage that change is for business partners to be connected. That way changes are managed together, with transparency on both sides. Our supplier chains are becoming increasingly global, with multiple ways of communication becoming increasingly complex.

Today we and many of our business partners are faced with some level of highly manual and error-prone processes.

Tomorrow business partners will be connected, sharing data electronically, automatically with minimal efforts, sharing in the benefits. We believe that if we can work together to make digitalization a success, we can share the following benefits.
