Wyeth works closely with our suppliers to ensure that invoices are paid in accordance with the terms and conditions of the agreement, purchase order, or other governing transaction.

Only valid original invoices will be processed for payment.  Copies will not be accepted.  Invoices, whether in hard copy or electronic format, should be sent to the location or address listed on the Purchase Order unless indicated otherwise. 

All invoices must clearly reference a valid Wyeth Purchase Order number.  Payment against invoices without a corresponding valid purchase order, except in specified exempt supply categories, is a violation of Company policy.  Please review the associated purchase order carefully to ensure that your full legal business entity name is listed and that all terms (eg, total cost, item quantities and descriptions, payment terms, freight methods, taxes) match those on the invoice.  If the invoice is for services rendered, it may require additional approval by a designated Wyeth business manager(s) or Finance Department employee(s). 

Notification of lost or destroyed checks or requests for check replacement or reissue should be directed to the Accounts Payable contact listed on your Purchase Order.  If the check is indicated as valid and uncashed, we will stop payment and reissue a replacement check.  Wyeth procedures dictate a minimum 30-day wait from the original issue date for check replacements or reissues to allow for mailing and/or processing delays.
