Invoices

Expand Energy and its affiliates require invoices to be submitted electronically through OpenInvoice.

It is important to us to pay our business partners on time. To avoid delays, follow our invoice guidelines and format and ensure you are sending your invoice to the appropriate entity as listed on the landing page.

OpenInvoice is Expand Energy’s electronic invoicing program. It offers several benefits, including:

Invoice tracking and improved efficiency
Direct customer communication
Remittance and payment detail
Same-day dispute resolution

Once you become an approved supplier, email supplierrelations@expandenergy.co m to set up an OpenInvoice account. Please include the below information in your email:

Quantity of invoices with Expand Energy and affiliate companies
Whether invoices are sent from multiple supplier names / sites
Name of existing OpenInvoice supplier account (if applicable)
Contact information for your company’s electronic invoicing administrator

Below are requirements to help ensure your invoice is submitted correctly and paid efficiently.

Do:

Submit one invoice per job
Submit your invoice within at least 90 days of the date of work
Ensure you are invoicing the correct Expand Energy entity and providing all necessary backup documents (signed field tickets, bid award sheets, etc.)
Include the relevant information for processing (invoice number and date, service date, description of work performed or product purchased)
Include correct cost object information, such as work orders, WBS elements and cost centers, as well as the rig or gathering location (if appropriate)
Submit a purchase order for controllable equipment (to be provided by a Expand Energy team member)

Don’t:

Group multiple jobs under a single invoice.
Wait too long to invoice; Expand Energy is not obligated to pay invoices past 90 days after the date of work
Submit invoices to the field for processing
Be inconsistent with your invoice amounts (make sure your invoice page matches the amount submitted in OpenInvoice)

Expand Energy utilizes PriceBooks within OpenInvoice to automatically validate electronic invoices submitted by our suppliers against the applicable contracted prices. Suppliers who reference PriceBooks when submitting invoices will experience fewer payment delays related to invoice validation and approval.

We reserve the right to require selected suppliers to reference PriceBooks when submitting invoices. If required, the Expand Energy PriceBook Administrator (PBA) will email suppliers 30 days in advance of the requirement which is to be referenced on all invoice submissions through OpenInvoice.

To establish PriceBooks in OpenInvoice, you can:

Attach pricing to a written agreement between your company and Expand Energy (the agreement, such as a Scope of Work, must be executed by the supplier and an officer of Expand Energy or a duly authorized designee) or
Enter into an Electronic Pricing Agreement (EPA) and memorialize pricing as described in the EPA section of this page

For more information, contact PBA@expandenergy.com.

For Suppliers with an active Electronic Pricing Agreement with Expand Energy, the following terms apply:

Pricing may be offered by Supplier and accepted by Expand Energy in the manner indicated below. Subject to the terms of the Electronic Pricing Agreement, the submitted pricing will become effective and binding on both parties upon Expand Energy’s acceptance.
- On or after August 1, 2023: Supplier may offer pricing to Expand Energy by submitting the proposed pricing to Expand Energy via the Pricing Agreement tool in OpenInvoice. Expand Energy’s acceptance of the pricing is indicated by Expand Energy’s approval of the pricing within OpenInvoice.
- Prior to August 1, 2023: Supplier may offer pricing to Expand Energy by submitting the proposed pricing, in a Microsoft Excel format provided by Expand Energy, via email to any Expand Energy Supply Chain representative. Expand Energy’s acceptance is indicated by written notification by the Expand Energy Price Book Administrator to any Supplier representative that Expand Energy accepts the pricing.
If Supplier and Expand Energy have entered into a written agreement that imposes a limitation on price changes, all prices established or modified pursuant to the Electronic Pricing Agreement are subject to the terms of that agreement, and any purported establishment or modification of contracted prices contrary to that agreement are void.
For information about entering into an Electronic Pricing Agreement, please contact your Expand Energy Supply Chain representative.

OpenTicket (OT) is used to document the quantity of goods received and services provided by your company. Financial approval of the goods and services are established at the time of invoicing and OT provides the option for automated receipt confirmation, resulting in faster payment processing.

As a supplier, you should submit an OpenTicket when both:

Goods and services are not issued on a Expand Energy PO
Your services require a Expand Energy employee to confirm delivery / verification of services

OT submission guidance:

OT allows you to enter your information directly, offering copy ticket, excel import and integration functionality with your field ticket system.
Your OT submission should be consistent in detail and charges summary to a signed paper field ticket. Additional information may be attached to the OT.
Please only utilize the Labor / Equipment / Material ticket type.
You must have the below data when submitting an OT.
- Requisitioner
- Service date range
- Subtotal amount without taxes
- PDF backup
- If provided, cost object (WBS / CC / WO)
