About this Product
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.
What you get
- A custom-built WooCommerce plugin, installed and activated by ECOSIRE on your WordPress/WooCommerce site (staging first, then production)
- MyInvois API integration configured with your registered TIN and Client ID/Secret, validated end-to-end against the LHDN preprod environment before go-live
- Checkout customization that collects buyer TIN, SST, business registration and MSIC fields, styled to match your existing checkout
- Mapping of your WooCommerce tax classes, product/MSIC codes and SST status to the MyInvois UBL document structure
- wp-admin settings panel for credentials, environment switching, consolidated-invoice scheduling, and the audit log
- Configuration and verification of the WP-Cron jobs for validation polling and consolidated B2C submission
- A handover document covering operation, the resubmission/cancellation workflow, and how the returned QR/UUID appears to customers
- Post-delivery support and schema-alignment updates as LHDN revises its e-invoicing requirements
Who this is for
Malaysian SME owner entering the LHDN mandate
Runs a WooCommerce store in Malaysia and has hit their phase of the LHDN e-invoicing rollout. Needs B2B orders submitted to MyInvois correctly without learning UBL or building an integration in-house.
Finance / accounts manager
Owns tax compliance and reconciliation. Wants every WooCommerce order to produce a validated MyInvois document with a stored UUID and QR, plus an audit log to defend against LHDN disputes — not a manual portal re-entry process.
WooCommerce store manager or agency
Manages the storefront day-to-day (or builds it for a client) and needs e-invoicing to work inside the existing checkout, HPOS order tables, and WPML/multisite setup without breaking the current theme or payment flow.

Frequently Asked Questions about Malaysia MyInvois (LHDN) E-Invoicing
Is this an instant download I can install myself?
No. This is a build-to-order plugin. ECOSIRE custom-builds it for your specific tax setup, then installs and configures it on your WordPress site. It is not sold on WordPress.org or WooCommerce.com and there is no instant download link — the $999 covers the build, installation, and MyInvois integration on your site.
How long does delivery take?
Typical lead time is about one working week from when you provide your MyInvois Client ID/Secret, registered TIN, and access to a staging site. Simpler single-store setups are faster; WPML, multisite, heavy tax-class customization, or a complex MSIC/product mapping add time. We confirm a firm date after a short scoping call.
What do you need from me to connect to MyInvois?
Your LHDN MyInvois Client ID and Client Secret (from the MyInvois portal), your registered company TIN and SST status, and access to a WordPress staging environment with WooCommerce. We validate everything against LHDN's preprod environment before switching your site to production.
Do I get ongoing support and updates as LHDN changes the rules?
Yes. After delivery, ECOSIRE supports the plugin and ships schema-alignment updates as LHDN revises the e-invoicing requirements, document format, or API. You own the plugin code outright; we keep it compliant. Specific support terms and duration are confirmed in writing at handover.
Will it work with my HPOS orders, WPML, and existing payment gateways?
Yes. The plugin reads and writes orders through WooCommerce's HPOS / custom-order-tables API rather than legacy post meta, so it is compatible with high-performance order storage. WPML and multisite are handled during the build, and it sits alongside your existing payment gateways — it submits to MyInvois on order completion and does not interfere with how payments are taken.
