Apache greatly values its relationships with its contractors and suppliers. Our focus is developing and maintaining supplier relationships based on cooperation, trust, reliability, and communication. We procure products and services through contractors and suppliers who demonstrate exceptional levels of quality and service, competitive pricing, solid delivery performance and effective after-sales support.

Below you will find information and various resources that will help you in conducting business with Apache.

Electronic Transactions

Apache utilizes the Ariba Network to electronically transact with its suppliers. The Ariba Network is a web-based marketplace that facilitates transactions between buyers and suppliers. Transacting on the Ariba Network gives suppliers improved standardization and control over order processing, along with better communication and visibility with Apache. Some of the key available benefits to Apache’s suppliers using the Ariba Network include:

  • Online portal for receiving and processing purchase orders
  • Ability to submit invoices electronically
  • Ability to submit service sheets electronically to document services rendered
  • Real-time invoice status updates as they are processed and readied for payment
  • Remittance (i.e., payment) notifications
  • Common platform for transacting with various customers

SAP Ariba offers two Ariba Network account types: Standard and Enterprise. Transacting on the Ariba Network is free for Standard Accounts. Enterprise Accounts are fee-based and offer additional functionality in addition to those included in Standard Accounts. Your company’s usage of the Ariba Network may differ depending on your account type. Click here to learn more about Ariba Network Accounts.

Apache is progressively enabling its suppliers to transact over the Ariba Network and will notify you when your company has been selected to participate. For any questions about Apache’s usage of the Ariba Network or its process for enabling suppliers on the Ariba Network, please contact

Suppliers Currently Utilizing Cortex™

*Suppliers currently using Cortex are to continue submitting invoices via Cortex using the existing process. Apache will notify you when you have been selected to begin submitting invoices via the Ariba Network and will assist you with that transition.

Apache had previously implemented Cortex as an electronic invoicing solution. Apache has now transitioned to use of the Ariba Network to further to improve operational efficiency and cost effectiveness with its suppliers and throughout the organization. As such, Apache is no longer accepting new suppliers on Cortex.

Existing users of Cortex are to continue submitting invoices via the existing process until otherwise notified. For general inquiries, please email or call 1-866-716-6272 (option 2). For supplier support, please email or call 1-866-716-6272 (option 1).

Electronic Payments

Apache has transitioned to electronic payments with its suppliers in furtherance of supporting a fully electronic procurement process from purchase to settlement. For this, Apache utilizes VendorIn, a web-based solution that allows your company to directly and securely maintain its profile and banking information for the purposes of facilitating electronic payments. Please note that VendorIn is only used to gather and maintain banking detail; your payments will still come from Apache Corporation. Your company’s participation assists Apache in ensuring its payments to its suppliers are accurate and timely. Some key benefits to Apache’s suppliers using VendorIn include:

  • Notification by email in advance of each payment
  • Improved cash flow – no waiting for a check in the mail
  • No cost and easy activation of your company profile
  • Ability to easily update your banking and remittance information through your VendorIn profile
