Purchase Guidelines

Disputed Payments

If there is a dispute with the vendor due to an error in the billing, the dispute must be communicated to the vendor within 21 days of receipt of the invoice. All details regarding the dispute should be well-documented. If the dispute is resolved in the vendor's favor, we are liable for any prompt payment interest that accrues. We are not allowed to change the invoice date or invoice received date to circumvent prompt payment interest. If the dispute is resolved in our favor, the vendor should provide a revised invoice with a current invoice date. If the vendor does not reissue the invoice with a new date, you may use the date the dispute was resolved as the invoice received date. You must clearly document why you are using that date as the invoice received date.
