  • Supplier statements
  • Quotes
  • Order acknowledgements
  • Packing slips
  • Altered Invoices
  • Any other documentation provided by the supplier

How to Request Service

Where to Submit Invoices

Email

Mail

U-M SSC Accounts Payable
3003 S. State Street

Healthcare Invoice Guidelines

  • All U-M purchase orders contain the appropriate “bill to” address for the transaction. Be sure you send the invoice to the address that appears on the purchase order.
  • If you are transmitting invoices that contain PHI, please make sure that you are transmitting them securely in accordance with our Business Associate Agreement (BAA) practices.
  • If you are transmitting PHI and do not have a BAA, please contact U-M Procurement Services at (734) 764-8212.
  • Do not email invoices containing PHI as this is not deemed the most secure method; please mail these types of invoices to the “bill to” address appearing on the purchase order.
  • All invoices must include at least one of the following: A valid U-M purchase order number or the valid U-M email address of the employee who placed the order with your company.

Campus Invoice Guidelines

Invoices must include a valid University of Michigan Purchase Order number (PO). Note: In rare cases (and non-standard), an invoice may not be tied to a PO, and therefore the supplier must include on the invoice the U-M email address of the U-M employee or group that placed the order.

For payment requests that are exempt from the Purchase Order standard, the unit must provide valid ChartFields/ShortCodes and a valid Expense Account Code. Payment requests that are not exempt from the Purchase Order process will be flagged as an Invalid Use of a Non-PO voucher and may be subject to further approvals.

If the unit receives an invoice from a supplier, the unit should remind the supplier to submit any future invoices directly to AP. The unit should also promptly forward the invoice to AP using one of the following methods:

  • Scan the invoice (retaining the hard copy for unit records) and attach it to an email addressed to accounts.payable@umich.edu or
  • Send the paper copy via campus mail to AP at the Wolverine Tower address (see above)
