How to Invoice Us

Bayer has launched a digitalization initiative for its Source-to-Pay process. One measure is to use SAP Ariba® Network for sending orders and receiving invoices.


With this initiative, Bayer is aiming to use a centralized platform where we can submit purchase orders to our suppliers, and have a secure and immediate exchange on the purchase orders and invoices. This will provide more transparency on the document status.
The increased efficiency and transparency are beneficial for us and you, our valued suppliers!
To help you with your information need, please kindly check the information below based on your status:

Step by step, Bayer is moving away from paper-based and manually transmitted business documents such as purchase orders, order confirmations, and invoices.

Bayer has partnered with Ariba (an SAP company) to conduct business electronically through the Ariba Network.

All suppliers are required to join the Ariba Network and to make paper-based transactions obsolete (where legally possible).

Exception for vendors onboarded in Ariba:

For invoices without Purchase Order reference, invoices can be submitted via email as a PDF attachment strictly following the invoicing guidelines. The Email PDF platform allows our suppliers to e-mail invoices as a PDF attachment. This will be received by a Bayer email address. Please follow the instructions found on the Email PDF Platform.
