Supplier Diversity at WestRock

What does this mean for WestRock suppliers?

Process Efficiency: This eProcurement initiative will continue to improve the procurement lifecycle by increasing our purchase order processing efficiency, payment accuracy, and reducing issues with the payment time to you.

Purchase Orders: WestRock purchase orders will be transmitted to your organization via the Coupa Supplier Portal(CSP). You will receive POs from the CSP, based on the method you select when configuring your CSP account. 

Invoices: Your organization will be able to transmit electronic invoices to WestRock via the CSP or based on the method you select when configuring your account. Please note that purchase orders will be required for all invoices submitted for payment.  

We thank you in advance for your support on this new way to conduct business with WestRock, and we look forward to our continued business relationship. Please visit this website for more information regarding this very important change.

Two options to fit your needs

Compare the two options to see which one works best for your business.


The Coupa Supplier Portal (CSP) is a free tool for suppliers to easily transact electronically. The CSP simplifies the management of multiple customers orders, relationships and documents. Depending on your specific Coupa configuration, you can manage content and settings on a customer-by-customer basis. The Coupa CSP provides online viewing of purchase orders, setting up delivery methods, creating pricing lists, sending invoices, advance ship notices (ASNs), checking payment information and more; all via a simple online portal.


Coupa offers similar benefits to the CSP for high volume customer relationships through cXML data integration. cXML requires integration of purchase orders and invoices directly into the suppliers fulfillment system. Generally, suppliers must engage IT resources to complete the one-time setup mapping exercise. Once complete, orders and invoicing flow seamlessly between supplier and customer.

Other Options

CSP and cXML are the most common options. Under certain circumstances, we may be able to offer invoice pick up by fTP or InvoiceSmash.
