This is a build-to-order Magento 2 / Adobe Commerce extension, not an instant Adobe Commerce Marketplace download. ECOSIRE builds it to your store's tax configuration and Peppol Access Point, installs it on your environment, and supports it after go-live.

The module ships as a standard composer package under app/code/Ecosire/InvoiceNowPeppol (or via composer require from your private repo). It wires into Magento's invoice lifecycle through an observer on sales_order_invoice_save_after and service contracts so that every Magento invoice is transformed into a Singapore PINT (SG PINT) UBL 2.1 document — the Peppol BIS billing profile mandated for the InvoiceNow network. A di.xml-registered generator maps order lines, GST tax categories, buyer/seller Peppol participant IDs, and IRAS-required fields into compliant XML.

Outbound documents are pushed to your chosen Peppol Access Point over the Peppol network (AS4), with delivery status, message IDs, and retries persisted against the order. A participant ID lookup validates the recipient's Peppol address (SGUEN / 0195 scheme) before sending, so B2B and B2G invoices don't bounce. Admin screens (ACL-gated under Ecosire_InvoiceNowPeppol::manage) expose document status, raw UBL, and a manual resend. A cron job sweeps failed transmissions.

Singapore GST (9%) is handled through tax-class mapping so standard-rated, zero-rated and exempt lines carry the correct UBL tax categories and IRAS GST e-invoicing readiness. Document data is exposed over REST and GraphQL for headless storefronts and ERP sync.

Because it's built to order, scope, Access Point credentials, and field mappings are confirmed with you up front. ECOSIRE handles installation, UAT against your Access Point's test environment, and ongoing support.
