Version 1.3 stable (revision 5): filter invoices by year, month or custom dates; find saved clients while typing; add or correct payment dates; undo a mistaken Paid status with confirmation; review monthly billed and collected amounts, receivable aging and payment insights; and export an accounting ZIP for a calendar or fiscal year. The accounting export is a preparation aid, not tax filing or a profit calculation.
