Invoicing Information for Service Suppliers

General Information

This document is intended to provide a reference for questions that may arise as Supplier performs work for the Union Pacific Railroad Company or other Union Pacific Corporation subsidiaries.  The term "Company" is used throughout this document to refer to the specific entity with which Supplier has an agreement.

The information contained in this document should in no way be construed as amending or modifying the terms of Supplier’s agreement(s).   Supplier is advised to review these terms and conditions to ensure full understanding of them and, if questions remain, contact the Supply Chain Department Services Procurement Center (SPC) at 402-544-0772 or spc@up.com.

It is the policy of the Company to award contracts based on such considerations as competitive prices, quality of service, technical expertise and familiarity with our operations, without regard to race, color, religion, sex, national origin, age, handicap or veteran status.

Payment Information

Suppliers are required to receive payments electronically via ACH (Automated Clearing House).  Failure to do so may result in delayed payments. 

Billing Method Available in Work Zone

Union Pacific does not accept supplier generated invoices.  Suppliers are required to complete electronic Service Entry Sheets (or SES) in Work Zone for work reporting and invoicing.  The SES is what is ultimately presented to UP as the invoice for payment for services rendered.  Service Entry Sheets (SES) are submitted to UP through Work Zone. Suppliers will create and submit SES transactions directly within the system based on the applicable contract and work performed. Each SES serves as both an electronic work report and invoice. Once the SES is verified and released for payment by the Railroad’s Representative, the information is routed to UP Accounts Payable for payment processing.

Retainage Billings

Billings for retainage amounts must be requested using the “Request Retention Release” tile in Work Zone.
