A PR (format PRXXXXX) number is assigned according to the time the requisition is processed internally in our system.

As a supplier, you only need to use the PO number reference on your invoices and on any communication with LP.

What is the expected turnaround time for invoice processing?

A manual invoice processed outside of the Ariba Network with a valid PO number will be processed within 48 hours. Once the invoice is in our system, it will be processed for payment based on the agreed upon terms.
