Hey! This is def possible. You will want to use a "Number" interface. For getting a sum of total amount, use "Field Summary" and select the Total License Fees field.
For total count of transactions, you could use "Record Count"

I want to show the totals within the list. I know how to do it with numbers, but I would rather have the list show the totals at the top or bottom.

I don't think so I'm afraid.  You could try using hierarchies for this?  You'd link each order to a record in another table that represented that month year, and then you'd use rollup / count fields to get the totals

Link to base

I prefer to use Dashboards when something in the list needs to be summed.

Thanks for the replies.  I guess my options are to add another interface page that is a list or use the number fields in a dashboard. It would be great to be able to show totals in a list within a dashboard.

I agree that this is a much-needed feature. Be sure to submit it as a feature request to support@airtable.com
