E-Invoicing replaces unstructured PDFs with structured, machine-readable XML data that accounting software can process automatically:

• Factur-X / ZUGFeRD: A hybrid PDF/A-3 document that looks like a normal PDF to humans, but contains embedded XML for automated accounting software.
• Peppol BIS Billing 3.0: The standard European e-invoicing format required for Business-to-Government (B2G) transactions.
• PINT (Peppol International): Universal e-invoicing standards adopted by Singapore, Japan, Australia, New Zealand, and Malaysia.

SemiAuto Invoicing Pro generates fully validated, standards-compliant e-invoices directly from WooCommerce orders.
