+The API returns a list of merchant statements and invoices.  By default, all invoices are returned with the most recent
+statements listed first.  Optional date parameters (`startDate` and `endDate`) can be used to filter statements by date
+range. 
 
+The `invoiceType` parameter can also be used to filter invoices by type.  Invoices could be conventional invoices, such
+as those generated when ordering terminals or gift cards, or invoices could be merchant statements.
