MX Merchant Ideas

Currently the Invoice screen/export has the following: Invoice #, Customer, Total, Status, Invoice Date, Due Date, Terms.  On this main screen, it would be helpful to have column for Total Paid, Balance Due (for those invoices open or partial paid.)  Additional, the invoice has the ability to enter a merchant specific PO Number field.  This would be helpful on the main screen and export so that merchant can sort/match to their other systems as needed.  (ps memo field exporting would be a bonus as well, but that might be asking too much:)
