Introduction to Invoicing

The invoicing API enables you to create and send invoices as well as track outstanding invoices. Your customers can pay using their preferred payment method from any device on a secure
National Australia Bank
hosted website. Automated reminders are available to help you remind customers of upcoming due dates or overdue invoices. For more information, see Invoicing API.
You can customize your invoice payment page to display your brand logo and color, as well as add custom messages to your invoice emails. Shipping information and phone numbers can also be collected at the time of payment. For more information, see Invoice Settings API.
The invoicing API uses
National Australia Bank
's
Unified Checkout Integration
to securely process payments so that you do not have to handle confidential payment data. Fraud and risk management tools are incorporated into
Unified Checkout Integration
to prevent fraud and reduce chargebacks. For additional security, you can add payer authentication to your invoice payment processing. For more information, see Add Payer Authentication to Invoicing.
To quickly and easily create, send, and manage invoices from your Microsoft Outlook desktop application,
National Australia Bank
offers the Visa Invoicing Add-In. The add-in can be downloaded and installed from Microsoft's AppSource. For more information, see Add Invoicing Add-In to Outlook.
IMPORTANT
The merchant is responsible for complying with any legal and tax requirements when issuing invoices to clients.
National Australia Bank
does not certify that the invoicing tool meets any such client requirements.
