to the Web Invoice Application. This application was developed for companies that supply material to North American railroads. It allows material suppliers to invoice the railroads electronically over a secure site at no cost. To use the application, follow these steps:   To use WIA, you must be a registered user (see the WIA Sign-up page). You will be provided with a company ID and password in order to log onto the site. Each time you sign on, you will be able to create and submit invoices. You can also review invoices already sent. For more information on how the process works or how to fill out the invoice form, see the WIA Help Desk. For technical support, contact Rail Customer Service. Or call Mike Ullrich or Alissa Catalan at 847-945-1000. 1. Contact your customer as listed on the Contact Info link. The customer will provide you with a "Customer Supplied Code" which you will need to include in your online registration. 2. Go to the Sign-Up page on this Web site, complete the registration and submit it. It takes approximately 2 days for the sign-up process to complete, after which time you will receive a company ID and password from Kleinschmidt (it's recommended that you change your password immediately so you have a unique, memorable code). 3. Once you've received your ID and password, you'll have secured access to send invoices. Just select the Doing Business link at the top of the page each time you wish to send an invoice, fill in the blanks, and submit it. 4. After submission, you may print off the completed invoice form for your internal records.Your invoice will be secured, sent to your customer and processed during their next invoice processing cycle (normally 1-2 days after submission). During processing, payment dates will be established in a manner consistent with the terms of the purchase order.
