Order number (or commitment number)

The purchase order number (or commitment number) appears on the purchase order issued by the department that made the purchase*

It must be mentioned in 2 places:

• On the invoice
• On the CHORUS PRO portal, in the "References / Commitment number"field

* If you do not know the purchase order number or the service code, contact the purchasing department directly - the one that placed the order or contract with you.
