Irish eInvoicing guide
Preparing accounting software for Irish eInvoicing
Preparation involves more than exporting XML. Software needs reliable semantic mappings, scenario coverage, inbound processing, versioned validation and operational controls.
Map data deliberately
Map customer and supplier identifiers, addresses, references, payment data, line calculations, VAT categories, allowances, charges and totals to EN 16931 business terms.
Test both directions
Generate representative invoices and credit notes, then test receipt, validation, duplicate handling, approval, posting and retention of the original structured document.
Plan for evolving Irish specifications
Keep Irish reporting and transport adapters separate from the core invoice model. Revenue has indicated that further technical material will be published, so version those integrations when authoritative details become available.
