How do I dispute my bill from Ariba?
If you believe your Ariba bill has been incorrectly calculated, you can create a dispute case by doing the following:
Your request will be sent to the billing team and you will be contacted by a representative.
Prior to creating a dispute case, we advise that you check your transaction activity report, which lists all the documents used to calculate your Ariba fees. You can view the transaction activity report by clicking the Display Transaction Activity Report icon which appears to the right of your bill under the Action column on the Open Bills tab.
