Our current system does not allow us to send invoices automatically by email; therefore, most invoices are sent by regular mail. There are a few invoices that can and will be sent by email. Below is a breakdown.

First and foremost, invoices are always sent to the billing contact, whether by mail or email. It is important to ensure this information is always up to date and that login information is shared with your accounts payable department or responsible individual.

The annual Accreditation Invoice (AAP) and the annual Proficiency Sample invoice (PSP) are mailed directly to the billing contact on the account. Annual Accreditation invoices are mailed in April of each year, and Proficiency Sample invoices are mailed in September of each year.

Invoices that are not sent annually are emailed at the time the service is requested or shortly after the service has taken place.

At this time, we do not charge late fees.

We accept ACH/Wire Transfer, checks, and credit cards.

We do accept purchase orders; however, an invoice is not considered paid until payment is received.

To avoid delays or account issues, all purchase orders must be submitted before the invoice is issued. Purchase orders can be submitted to payments@aashtoresource.org. Please include the applicable account number with your submission.

If you would like to pay by ACH or Wire Transfer, please contact us at payments@aashtoresource.org, and we will send the information promptly.

AASHTO does not charge any fees to receive wire transfers. However, wire transfer fees may be assessed by the sending bank and/or intermediary banks involved in the transaction.

It is the sender’s responsibility to confirm these fees in advance and ensure that AASHTO re:source receives the full invoice amount. If an invoice is not paid in full due to wire transfer fees, services will not be provided until the remaining balance is received.

Remittance advices are not required; however, we kindly request that you provide them.

Remittance advices can be sent to payments@aashtoresource.org and should include the invoice number(s) associated with the payment. Without this information, we may be unable to match the payment to an invoice.

We are not responsible for delays in services or participation due to payments that cannot be identified.

Checks can be mailed to:

AASHTO 2
PO Box 711013
Philadelphia, PA 19171-1013

Please include the invoice number(s) with your remittance for faster processing.

Please do not overnight or send payment signature required.

Payments sent to AASHTO instead of AASHTO re:source take longer to process due to separate customer databases.

If the check has been cashed, please email a copy of the back of the cashed check to payments@aashtoresource.org. This information helps us locate and apply the payment.

If the check has not been cashed, you may allow additional time for processing or stop payment and reissue the check.

Responsibility for timely payment remains with the payer. We are not liable for checks lost in the mail or any resulting impacts due to unpaid invoices.

Payments sent to the PO Box are received directly by our bank and deposited immediately upon receipt. We receive a payment report the following business day.

If the check has not been cashed, you may allow more time for processing or stop payment and reissue.

Responsibility for timely payment remains with the payer. We are not liable for checks lost in the mail or any resulting impacts due to unpaid invoices.
