+This module extends the FatturaPA import functionality to automatically retrieve payment terms from the XML invoice.

@@ -0,0 +1,12 @@
+When importing an electronic invoice (FatturaPA):
+
+1. If the partner has "Retrieve due dates from XML" enabled, the system will automatically set this option on the invoice
+2. When you validate the invoice, the system will:
+   - Read the DatiPagamento section from the XML
+   - Extract DataScadenzaPagamento (due date) and ImportoPagamento (amount) for each payment line
+   - Generate account.move.line entries accordingly
+   - Validate that the total amount matches the invoice total
+
+The payment data is extracted from:
+- DatiPagamento/DettaglioPagamento/DataScadenzaPagamento (due date)
+- DatiPagamento/DettaglioPagamento/ImportoPagamento (amount)
