Invoicing Instructions
Pattern Energy Group LP and its affiliates have a centralized receiving and processing system for all invoices. Follow all steps to ensure prompt processing and avoid payment delays.
-
All invoices must be addressed to the correct legal entity for which you are providing services and a clear description of the project for which you are billing.
- The type of work performed must be included on each invoice (e.g., material number, description of the Products and/or Services, quantities, unit price, freight charges, and totals), and project descriptions such as “miscellaneous” or “various” are not acceptable. Please contact the person at Pattern who engaged your services if you are unsure what description must be used.
- The Seller is responsible for any and all taxes and import duties unless the Buyer has expressly assumed in writing the obligation to pay such costs.
-
Seller will issue an invoice within ten (10) days following the end of the month in which the Products or Services are delivered.
Buyer shall have no liability for payment of any invoices which are not issued within the foregoing time requirement. Each invoice will be due and payable forty-five (45) days following its receipt by Buyer or required by agreement.
-
Submit only one invoice per project (i.e., do not bill for multiple projects or Purchase Orders (PO) per invoice).
