The Billing page enables you to monitor your unit usage during the current subscription and have access to past invoices. This is a feature restricted to Portal users with the owner role.
Unit usage for your currently subscription will be displayed here. You'll be bale to see the duration of the current plan, the total of units contracted, the number of units already used and a breakdown by content type of the current month. Notice that Free Units are the ones included in your subscription fee, while Payable units are the ones that have been used while exceeding the agreed number or that have been applied when incurring in a Fair Usage penalty.
In the second chart you can see the total of units consumed by month according to content type.
This section differs from Usage reporting in the sense that it is not focused on individual messages or articles, and doesn't look into operational aspects such as brands, agents, content types or LPs. It lets you know how much of your contracted usage there is left to spend by bundling it together and it uses the concept of Unit instead. A Unbabel unit is the calculation resulting from the usage unit multiplied by its unit ratio.
Ask your CSM should you want to learn more about how units are consumed.
You can check on your past invoices on the Billing page. Here, your invoices will be listed with their number, due date, amount and payment status.
You can also download a PDF version of the invoice directly from the Portal by hovering over the entry and clicking the download button that appears at the end of the row.
