Malaysia MyInvois E-Invoicing Connector

Fonctionnalités clés

Real-time submission of e-invoices to the LHDN MyInvois portal on Shopify order webhooks (orders/paid, orders/create, refunds/create), not batch CSV upload

Server-side validation of each document against the MyInvois UBL schema before submission, with clear rejection reasons surfaced back to you

Writes the returned MyInvois UUID, validation status, submission timestamp, and LHDN QR code back to the Shopify order as metafields for use in invoice templates and emails

SST (Sales and Service Tax) mapping that translates Shopify tax lines and product tax codes into MyInvois-compliant classification codes

Consolidated B2C e-invoice support that aggregates retail orders without a buyer TIN into periodic consolidated submissions per LHDN rules

Self-billed e-invoice handling for applicable supplier and import scenarios

Credit note generation tied to Shopify refunds and returns, referencing the original e-invoice UUID

Threshold-phase rollout configuration so you enable the connector for your mandate wave by annual turnover, including a validation-only dry-run mode

Buyer TIN, SST registration number, MSIC code, and business identifiers captured and validated via store and customer metafields

OAuth-authenticated private Shopify app with scoped Admin API access (read_orders, write_orders/metafields) — no broad permissions requested

Submission audit log with retry and back-off handling for transient MyInvois API errors and rejected documents

Built and tested against the MyInvois sandbox before any live document is sent, with a controlled cutover to production

À propos de ce produit

Malaysia's MyInvois mandate is rolling out in phases by annual turnover, and Shopify has no native path to LHDN. This connector closes that gap. ECOSIRE builds, installs, and supports a private Shopify app wired into your store's Admin GraphQL API and order webhooks so that every qualifying sale is mapped to the MyInvois UBL document model and submitted to the LHDN MyInvois portal in real time — not via a CSV you upload at month-end.

When an order is paid, a Shopify orders/paid (or orders/create) webhook triggers the connector. It reads line items, taxes, customer TIN, and your business identifiers from order data and metafields, builds the validated e-invoice payload, submits it to MyInvois, and writes the returned UUID, validation status, and LHDN QR back onto the order as metafields — ready for your invoice template, packing slip, or customer email.

The build covers the real-world cases Malaysian merchants hit: SST tax-code mapping from Shopify tax lines, consolidated B2C e-invoices for retail orders without a buyer TIN, self-billed scenarios, and credit notes for refunds and returns. Threshold-phase configuration lets you switch the connector on for your mandate wave and run in a validation-only mode first.

This is build-to-order, not an instant App Store install. After purchase we scope your tax setup, build against the MyInvois sandbox, install on your store, and verify live submissions with you. One-time price USD 299; ECOSIRE retains the code, hosts the middleware, and provides ongoing support. We are not LHDN and do not provide tax or legal advice — your accountant confirms classifications; we make the technical submission correct and reliable.

Pour qui c'est

Malaysian Shopify retailer entering a mandate wave

A B2C store owner whose annual turnover places them in an upcoming MyInvois phase. They need consolidated B2C e-invoices submitted automatically without re-keying orders into the LHDN portal.

Finance or compliance lead at a growing Shopify brand

Responsible for SST correctness and audit trails. Wants validated submissions, UUID/QR on every invoice, and a clear log of accepted and rejected documents rather than a manual month-end scramble.

Accountant or outsourced bookkeeper serving Malaysian SMEs

Manages compliance for several merchants and needs a reliable, hands-off technical bridge between Shopify and MyInvois so their clients stay compliant while they focus on classification and reconciliation.

Foire aux questions sur Malaysia MyInvois E-Invoicing Connector

How long does delivery take, since this is built-to-order?

After purchase we start with a short scoping call to review your tax setup, SST registration, and mandate phase. A typical build, sandbox validation, installation, and live cutover takes about 2 to 4 weeks depending on the complexity of your catalog and tax mapping. You will be involved at the sandbox-validation and production-cutover steps so nothing goes live unverified.

Is this an instant Shopify App Store download?

No. This is a custom private app that ECOSIRE builds, installs on your store via OAuth, and supports. There is no public App Store listing or self-serve install. That is deliberate — your SST mapping, business identifiers, and mandate-phase settings are configured specifically for your store and verified against the MyInvois sandbox before any live document is submitted.

What happens with ongoing support and MyInvois rule changes?

ECOSIRE hosts and maintains the middleware that talks to the LHDN MyInvois API, so when the API or document schema changes, we update the connector. Your one-time build price covers installation and initial support; ongoing maintenance and rule-change updates are available under a support arrangement we agree on at handover. You will not be left to patch a private app yourself.

How does it handle B2C orders where the customer has no TIN?

Retail orders without a buyer TIN are handled through MyInvois consolidated B2C e-invoicing. The connector aggregates qualifying orders and submits them on the consolidated cadence LHDN permits, rather than rejecting them. If a B2B buyer does provide a TIN and SST number via checkout or metafields, that order is submitted as a normal validated e-invoice instead.

Do you guarantee tax compliance and act as our tax advisor?

We make the technical submission correct, validated, and reliable — schema-valid documents, proper UUID/QR handling, and accurate mapping of your configured tax codes. We are not LHDN and do not provide tax or legal advice. Your accountant confirms SST classifications and which orders fall under the mandate; the connector then submits them faithfully and keeps an audit trail.
