Malaysia's LHDN e-invoicing mandate requires every B2B (and increasingly B2C) sale to be submitted to the MyInvois portal as a validated UBL 2.1 document — something WooCommerce core was never built to do. This is a build-to-order plugin: ECOSIRE custom-builds it for your WordPress site, installs it on your server, and supports it after purchase. It is not an instant WordPress.org or WooCommerce.com download — there is an honest delivery lead time while we wire it to your exact tax setup, product catalog, and SST status.

Once live, the plugin hooks into WooCommerce order lifecycle actions (woocommerce_order_status_completed, woocommerce_checkout_create_order) to map each order to a MyInvois UBL e-invoice and submit it through the LHDN API using your registered TIN and client credentials. It collects the buyer's TIN, SST registration number, business registration number and MSIC code at checkout via custom fields, so documents pass LHDN validation on the first try instead of being rejected.

The plugin handles the asynchronous validation flow: it stores the submission UUID, polls MyInvois via WP-Cron for the validated status, then writes the returned QR code and Long ID back to the order and invoice PDF/email. For B2C, it supports consolidated invoice generation on a schedule. Customers who didn't supply tax details at checkout get a self-service e-invoice request form tied to their order.

Built HPOS-compatible (WooCommerce custom order tables), it stores credentials securely in wp-admin settings and logs every API exchange for audit. WPML/multisite and staging-vs-production MyInvois environments are handled during the build. You own the code outright; ECOSIRE keeps it aligned as LHDN's schema evolves.
