Invoicing Bayer

At Bayer we are committed to ensuring a timely and efficient payment of all our suppliers for goods and services provided while supporting our target of achieving environmental sustainability through the adoption of e-solutions.

How to Invoice Bayer

In this section we offer basic information and key requirements to ensure a successful payment process, how to transact with us and whom to contact.


Bayer has various fully compliant solutions in place, which allow invoices to be received electronically all over the world. Electronic invoicing is one step being taken to improve the efficiency of invoice processing. To meet supplier and business needs alike, Bayer has partnered with external supplier networks in order to offer flexible solutions:

  • ARIBA’s cloud-based supplier portal
  • ePDF platform

Advantages include faster processing, reduced postage and printing costs, monitoring of payment status and avoidance of lost invoices. To receive more information about the different e-invoice solutions please refer to below contacts :



Paper invoices sent to Bayer‘s accounts payable department are scanned before being entered into the relevant systems. Therefore it is very important that the invoice document is of high quality and easy to read. We recommend that the invoice is on white A4 or US Letter size paper, clearly printed in black and white and that highlighter pens are not used.

Paper invoices should be sent to the address specified on the purchase order. In general, the invoice has to meet all legal requirements.


Furthermore, to avoid delay in payment, it is important that the invoice includes the following mandatory information which should match the details provided in the purchase order (PO):


  • The invoice must be addressed to the relevant Bayer company including the correct company name and full address. The addresses of Bayer subsidiaries are listed in the addresses & contacts per Bayer subsidiary list (PDF).
  • The invoice must adhere to country-specific requirements predefined by legal regulations (e.g. VAT).
  • Supplier’s full name and address
  • The word “invoice” (or if a credit, the words “credit note”)
  • Invoice number and invoice date
  • Value and currency
  • Description of goods and services supplied
  • Bayer PO number and PO item number (if applicable)
  • Name and contact details of Bayer representative
  • Any unique reference number or information requested by the Bayer representative
  • The invoice must specify advance payments and final settlements, and always indicate already paid advance payments.


The invoice should list separately the net value of goods and services, the rate and amount of VAT, and the total/gross value of the invoice.


Please note that any invoice which does not comply with the above requirements will be returned to the supplier for resubmission. This may lead to a delay in payment.

Correct Invoicing for On-time Payment

To ensure timely and accurate handling of your delivery and payment of your invoice(s), we request that all suppliers fully comply with the following instructions:


  • Only one purchase order (PO) should be billed per invoice.
  • The invoice should match the PO (e.g., if the PO is split into separate line items; the invoice should also be split into separate line items).
  • Unit price, unit of measurement and currency must be the same as on the PO.
  • PO line item number needs to be referenced on each invoice line item.
  • Invoice payment terms must match PO payment terms.
  • The bill of lading or packing slip number is helpful to streamline internal processes.
  • Valid bank account data must be included on the invoice.


Regarding Logistics Ancillary Costs (e.g., demurrage costs, detention, etc…).

  • It is mandatory to outline:
    • Location
    • Time unit (e.g. hours, days)
    • Price per time unit
    • Type of additional logistics costs
  • No surcharge on third party costs are allowed.
  • Please state such costs separate and clearly visible on the invoice as a separate item.


Any missing information or deviations from the above can lead to longer internal processing times which therefore may lead to delays in payment.

Payment Terms

Payment terms are negotiated with suppliers in advance. Invoices are always paid according to the negotiated payment terms provided in the purchase order issued by Bayer.

In case of a discrepancy in the purchase order payment terms please contact the respective Bayer representative.
