For fast and efficient payments, please submit your invoices through electronic invoicing (EI). EI provides several benefits, including:
- Invoice tracking
- Payment cycle time
- Customer communication
Once you become an approved supplier, the EI onboarding process is quick and easy. To get started,
email Supplier Relations. We can determine if your company is eligible for EI and can answer any questions. Please make sure you have the following information on hand:
- Type of products or services being billed
- Software used to create invoices
- Quantity of invoices with Chesapeake and affiliate companies
- Whether invoices are sent from multiple field offices
- Whether multiple properties are billed on invoices
All suppliers must have a Master Services Agreement or Non-Disclosure Agreement on file before EI can begin. Chesapeake uses Oildex for its EI program. Oildex will begin the setup process and provide technical support where necessary.
Invoice Submission Methods
Suppliers may use any of the following to submit electronic invoices through Oildex:
- Online web forms (requires a computer and Internet connection)
- QuickBooks add-in that allows users to create and transmit e-invoices
- Other standardized data formats or spreadsheets (CSV, EDI, PIDXML, etc.)
Electronic Pricing and Invoicing
Chesapeake uses OpenInvoice Price Books to automatically validate electronic invoices submitted by its suppliers against the applicable contracted prices. Once enabled in the electronic invoicing system, suppliers who reference Price Books when submitting invoices will experience fewer payment delays related to invoice validation and approval.
Chesapeake reserves the right to require selected suppliers to reference Price Books when submitting invoices. The Chesapeake Price Book Administrator will notify suppliers via email 30 days in advance of requiring Price Book(s) to be referenced on all invoice submissions through OpenInvoice. For more information, please contact Chesapeake’s Price Book Administrator at PBA@chk.com.
OpenInvoice Price Books are established in one of two ways: first, by attachment of pricing to a written agreement between the supplier and Chesapeake that is executed by the supplier and an officer of Chesapeake, or their duly authorized designee (e.g., a Scope of Work); or second by entering into an Electronic Pricing Agreement and memorializing pricing as described below.
Electronic Pricing Agreement
Suppliers who have entered into a valid Electronic Pricing Agreement with Chesapeake may offer pricing to Chesapeake by submitting the proposed pricing, in a Microsoft Excel format provided by Chesapeake, via email to any Chesapeake Supply Chain representative. Upon written notification by the Chesapeake Price Book Administrator to any supplier representative that Chesapeake accepts the pricing, such pricing will become effective and binding on both parties pursuant to the terms of the Electronic Pricing Agreement. For information about entering into an Electronic Pricing Agreement, please contact your Chesapeake Supply Chain representative.
