Payment Information

Payment Information and Options

ASLO accepts several methods of payment detailed below. Online forms accept credit cards but also allows you to pay later by check or wire transfer. Please follow the instructions below and read the brief FAQ on common payment issues below. Payments are made in U.S. Dollars.

Note that the United States, where ASLO collects fees, does not participate in IBAN.


Every transaction made via the ASLO web site creates an invoice. You may pay by credit card at checkout or choose to pay later by check or wire transfer. All invoices are due within 30 days from date billed. A paid invoice will be sent to you via email when a successful payment is made.

Deferring Your Payment

You may defer your payment by using the “Pay by Check” feature at checkout. You may then log back into your ASLO profile and complete your payment by credit card, or send a check by mail, or arrange a wire transfer (see below).

Credit Cards

ASLO accepts Visa, MasterCard, American Express and Discover.

Common reasons for declined credit card transactions:

  • Your profile address does not match that of the billing address for the credit card. Check that your ASLO address matches your credit card's billing address.
  • Your university or organization credit card requires pre-approval or has a specific list of approved business types for purchases. Check with your organization.

If you accidentally charged a transaction on your personal credit card instead of a university/organization card. Send an email to [email protected] with details of the situation.
