After you log into your portal account:
- On the lower left side, click on Invoices, then Search.
- Select the month you are needing to reference. Note you need to select the last day of each month as that is the closing date of that invoice. So for January, select January 31st. Hit the apply button and get deliveries.
- The invoice number is a link, so click that number.
- Scroll to the bottom of that page and the items on that invoice are listed.
