Generating a membership renewal invoice is easily done by logging into the system and going to 'My IACCM', which is accessed by clicking the down arrow next to your name displayed on the upper right-hand corner of the window when logged in. Then go to the 'My Account' menu item will then appear in the drop-down menu at the top of the page. There you will see a button to 'Renew' your membership.
Simply go through the registration process and when the payment page comes up, use the 'Generate Invoice' button on the right-hand side to create your invoice.
Once your membership invoice is paid, your account will be updated.
