Do you have 5 invoices or 3 in your example?
Are you counting invoices or computing a total (sum) of the invoice totals? (Both are possible)
What layout design must this be part of?
A summary report based on invoices could easily produce this report:
Invoiced Paid (count and/or total)
Invoiced Not Paid ( count and/or total)
Quotaition (count and/or total)
The individual invoices can be listed under each of the above rows or it can set up just to show these three rows.
If you want this as part of a more complex layout, then a portal, or possibly 3 filtered one row portals can be used to show the subtotals and/or counts for each type of invoice record.
In both cases, you can filter to a specific subset of the invoice records or show totals/counts for all the records in your table.
