FREQUENTLY ASKED VENDOR QUESTIONS:

Why is my invoice not paid?

A/P requires several items on an invoice to ensure proper payment.

• Invoices should be mailed to

Accounts Payable

Controller's Office

University of Massachusetts / Amherst

405 Goodell Building

Amherst, MA 01003

 

• Invoices should have:
  • Name of Vendor
  • Payment Remit Address of Vendor
  • Valid Purchase Order Number (extremely important)

    examples of valid purchase order numbers:

    • UMass Amherst Purchase Orders start 0001 and consist of 10 digits.
    • Auxiliary Service Purchase Orders start with N.
    • Department who placed the order and contact name of person who placed the order are helpful.

  • Contact Name within the department who ordered is also helpful.

If your invoice is missing a valid purchase order number this will delay your payment due to the fact that the invoice will then need to be researched.

What is this check for?
