Procurement Vendor Information


On May 1, 2009, the commonwealth began using a new mailing location for all invoices associated with a purchase order.  (Exceptions exist for invoices associated with several agencies, however.   Please review the list at the bottom of this page before mailing.) If they are not mailed directly to this address, payment may be delayed or your invoice may be rejected.   The new address is:

Commonwealth of Pennsylvania – PO Invoice
PO Box 69180
Harrisburg, PA  17106

When you submit an invoice against a purchase order, you must include the following information on the invoice:

  • Purchase Order Number
  • Invoice Date
  • Invoice Number
  • Gross/Total Amount   

The following additional information will help us process your invoice more promptly.   However, it is not required for payment.

  • Supplier Name and SAP Vendor Number (if available)
  • Supplier Remit-To Address and Fax Number
  • E-mail Address of Supplier Contact Person
  • Purchase Order Line Item Information (i.e. Description, Material Number, Quantity, Unit Price and Amount Due)
  • Delivery Date  

When you submit an invoice associated with a purchase order, please remember the following:

One invoice per envelope. We would prefer to receive one invoice per envelope.  However, if you include multiple invoices in one envelope, all of those invoices must be associated with the same purchase order.

One copy of each invoice.Multiple copies of invoices should not be sent to the new mailing address.

Only invoices and credit memos should be submitted to the new mailing address.Please do not send statements. Any other correspondence, such as order confirmations and goods receipts, should be sent to the agency for which goods or services were provided.
