IT applications and digitalization programs
Digital transformation enables us to use innovative IT applications and tools to make collaboration with our suppliers even faster, simpler and more efficient. These applications cover both the strategic procurement process (Source-to-Contract) and the entire operational process from placement of the purchase order to invoice receipt (Purchase-to-Pay).
How we link up with our suppliers electronically
Electronic Supplier Integration ESI+
The digitalization program ESI+ is an end-to-end solution for the optimization of the operational procurement processes between ourselves and our suppliers. Thanks to the electronic integration of Siemens suppliers, the process, from purchase order to invoice receipt, is standardized and digitalized. This improves data flow and makes us jointly even faster, more efficient and more transparent. At the same time, we reduce the effort involved for ourselves and our suppliers alike. With the ESI+ program we are thus laying the foundations for our future digital collaboration.
