Ariba Supplier Communication - Phase II

Dear Ariba Supplier,

How will purchase orders already in the Ariba Network be processed during this upgrade?

Purchase Orders (PO) in the Ariba Network at the time of the upgrade will be cancelled and the order will be recreated with a new purchase order number within the new ERP. The cancelled Ariba purchase order will be transmitted through the Ariba Network and will reference the new purchase order number. The new purchase order number should be used for future invoices.

Future invoices referencing the new NON ARIBA PO should be sent to Please reference the new PO. You can also look up the new PO on the Purchase Order Cross Reference listed on this webpage.

For all future PO’s, please follow the invoicing instructions linked within the purchase order.

How should my company submit invoices for purchase orders already transmitted through Ariba?

Dow Accounts Payable will handle the processing of invoices already submitted through the Ariba Network. If you are awaiting payment on an invoice that was submitted through the Ariba Network prior to August 2, 2017, these invoices will be picked up and paid. Please do not send in another invoice for these charges.

Thank you in advance for your cooperation and support during this process. If you have any questions or require additional information, please do not hesitate to call your current Dow representative.
