If a dispute arises, the following information is necessary to resolve your dispute:

Unpaid Invoice or Incorrect Payment (Quantity)

If you have an unpaid invoice, or have received payment for a quantity that is incorrect, please email the following to your Allison Accounts Payable Analyst: 

• Copy of original invoice
• Copy of proof of delivery (for goods delivered to any Allison dock)
• A detailed explanation of the situation

Incorrect Payment (Unit Price)

If you have received payment, but believe that the unit price is incorrect, please contact your Allison buyer. The Allison Accounts Payable department cannot resolve pricing disputes.

Invoice Status

Please do not request the status of an invoice that is not due to be paid, the Allison Accounts Payable department is unable to respond to these inquiries.

Allison payment terms are Net 60. Payments are made on the second business day of the second month following the receipt of your goods or services.

For example, if you shipped widgets on July 29 and Allison received the shipment on August 1, your payment will be made on the second month (October) and the second business day (October 2).

If you do not ship goods, but perform a service for Allison, your payment is based on your invoice date.

For example, if your invoice is dated July 29, Allison will make a payment on September 2.
