Hi Team:

Please in the report sfs_cash_report add 2 new subtotal zone in the foot area:

The subtotal zone 1 must be:
The sum of the total with tax of all invoices not paid and with date diffrent to date invoice, the fixed title of this zone must be "Term Bills"

The subtotal zone 2 must be:
The sum of the total with tax of all invoices paid and with date equal to date invoice, the fixed title of this zone must be "Counted Bills"

in the i18n folder please add the next terms:
Term Bills = Facturas a Credito
Counted Bills = Facturas de contado
