Attachment 1 Confirmation of Service(OS-501).pdf

The document is a Confirmation of Service Form (OS-501) issued by the Pennsylvania Department of Transportation, designed as an administrative form for contractors to document and confirm services rendered under a purchase order. The form provides a structured template for contractors to record detailed information about services performed, including line items, quantities, units of measure, and pricing. It requires contractors to complete specific fields such as date of service, SAP vendor number, contractor name and address, purchase order number, and individual line item details.

The form includes specific instructions for completion, emphasizing that contractors should not submit an invoice for payment until a fully executed OS-501 is received back from the appropriate PennDOT representative. The form is intended to be submitted electronically via email after the contractor signs and dates it. Key administrative requirements include entering precise information as it appears on the fully executed purchase order, creating separate entries for each delivered line item, and ensuring that goods receipts are entered in SAP within 48 hours per management directive. The form serves as an internal control and documentation mechanism for verifying and approving service-related payments within the Pennsylvania Department of Transportation's procurement process.
