About this Product

Malaysia MyInvois E-Invoicing for WooCommerce connects your WooCommerce store directly to the LHDN MyInvois platform so every order can become a validated, digitally signed e-invoice without re-keying anything into the MyInvois portal. This is not an instant marketplace download — ECOSIRE builds the plugin against your exact tax setup, installs it on your WordPress site, and supports it after go-live.

On the WooCommerce woocommerce_order_status_completed (or processing) hook, the plugin assembles a UBL 2.1 document from the order, posts it to the MyInvois API, captures the Unique Identifier Number (UUID) and validation status, then stores the long ID and QR code back on the order. We use a custom order meta layer that is HPOS-aware (works with WooCommerce custom order tables and the legacy post store), so your dashboard and emails always show the correct e-invoice state.

The build wires in the fields LHDN expects — buyer and supplier TIN, SST registration number, MSIC code, classification codes and tax type/percentage — exposed in wp-admin so staff can correct or supply data per order or per customer. Document signing is handled with your certificate, and WP-Cron drives retries, status polling and consolidated e-invoice generation for B2C orders within the monthly window.

Because it's built to order, ECOSIRE handles sandbox onboarding, ID/client-secret configuration, mapping your products to the right tax codes, and WPML/multisite considerations if you run multiple stores. You get a plugin tailored to your catalog and obligations — plus a real human to call when LHDN changes the spec.

Frequently Asked Questions about Malaysia MyInvois E-Invoicing for WooCommerce

How long does delivery take after I order?

Because this is built to order, ECOSIRE scopes your tax setup, catalog and MyInvois credentials first, then builds, installs and tests the plugin on your site. Typical delivery is around 2 to 4 weeks depending on catalog complexity, consolidated-invoice requirements and how quickly LHDN sandbox access and certificates are available. You get a confirmed timeline before work starts.

Is this an instant download from WooCommerce.com or WordPress.org?

No. There is no instant marketplace download. The plugin is custom-built for your store and installed on your WordPress site by ECOSIRE. This avoids the generic-plugin pitfalls of mismatched tax codes, TIN handling and HPOS conflicts, because the integration is configured against your actual data and LHDN profile.

What ongoing support and updates are included?

Each engagement includes a post-launch support window covering bug fixes, configuration help and updates when LHDN changes the MyInvois API or document spec. We monitor for breaking changes and can ship updates to your site. Extended support and maintenance plans are available so the integration stays compliant as the rollout and rules evolve.

Does it work with HPOS and my existing WooCommerce setup?

Yes. The plugin is HPOS-aware and reads/writes order data correctly whether you use WooCommerce High-Performance Order Storage (custom order tables) or the legacy post-based store. We verify compatibility with your theme, payment gateways and any order-related plugins during installation.

Do I need my own LHDN credentials and digital certificate?

Yes. MyInvois submission and digital signing require your organisation's own LHDN MyInvois client ID, client secret and signing certificate, since invoices are issued under your supplier identity. ECOSIRE guides you through sandbox onboarding and production registration and wires those credentials securely into the plugin settings.

Can it handle B2C consolidated invoices and refunds?

Yes. B2C orders that don't request individual e-invoices can be aggregated into a consolidated e-invoice and submitted within the monthly LHDN window via WP-Cron. Refunds and cancellations trigger the corresponding credit-note or cancellation document flow tied to your WooCommerce order actions.
