Invoicing & Tracking

​In an effort to provide our suppliers with superior information services, Bristol-Myers Squibb has developed a web-based application called Expenditures Inquiry to provide suppliers with the ability to review invoice account history and payment information on the Internet. The Expenditures Inquiry also contains functionality that allows the supplier to e-mail invoice-related issues to Bristol-Myers Squibb. E-mails are sent automatically to the appropriate Bristol-Myers Squibb end-user and copies of the e-mail are sent to Accounts Payable Front Office, as well as to the supplier generating the e-mail.

If your company does not already have access to this service, you may request access, please contact

The Expenditures Inquiry tool is available 24 hours a day/7 days a week. However, if you need to speak with someone please contact
