Login to your account and select the MY ACCOUNT tab at the top of the page then select the ACCOUNTING icon - now select INVOICES. You can view and print a summary or detail of your Invoices. You can also get a PAID/NOT PAID status of your Invoices.
Note: If you are on NET 30 Billing then you may not see the most current Invoices for the Month. Invoices are generated on the 1st day of every month for the prior month. If you pay by Credit Card then your Invoices will be current based on your last order.
