Information for suppliers

Welcome to SIG.
We value trusted partnerships, transparency, and responsible business practices. Here you will find important information to support a smooth and successful collaboration with us.

SIG Procurement Application tool

Within the SIG Procurement Application tool we manage all procurement related activities. This digitalized way of working creates transparency on relevant data and streamlines underlying processes. It builds the foundation for a sustainable collaboration between us and our suppliers.

In the Supplier Value Management module we collaborate with potential, new and existing suppliers in a transparent and efficient way. The underlying process enforces us to follow the CSR requirements and to manage supply risk.

The Sourcing module enables us to work collaboratively to build, issue and evaluate sourcing events such as eAuctions in a secure online environment.

Contract Lifecycle Management improves the tracking, negotiation and management of contracts to ensure compliance at all stages of the supply relationship, reducing supply chain risk.
