Malaysia MyInvois & SST Localization for Business Central

Fonctionnalités clés

LHDN MyInvois submission: event subscribers serialize posted Sales Invoices and Credit Memos into UBL 2.1 JSON and submit via an OAuth2 HTTP client to the MyInvois API, then poll for Valid/Invalid/Cancelled status

SST tax code engine: Sales Tax and Service Tax rates mapped through BC VAT Posting Setup, with exemption codes, taxable-vs-exempt classification and tax-type tagging on document lines

Consolidated e-invoice generation: a job queue entry aggregates B2C transactions for a period into a single consolidated MyInvois submission per LHDN rules

Validation QR code: stores the LHDN-returned UUID, long ID and validation link, and renders the QR code on the printed/PDF invoice via a report extension

Statutory report export: SST-02 return data and MyInvois transaction registers exported to the file formats LHDN and Customs expect

Document status tracking: a FactBox and list page show per-document MyInvois state (Pending, Submitted, Valid, Rejected) with the rejection reason returned by LHDN

Cancellation and rejection handling: supports the 72-hour MyInvois cancellation window and buyer-rejection workflow with linked credit notes

Self-billed and import e-invoice support for supplier scenarios that require the buyer to issue the e-invoice

TIN, SST registration and MSIC code validation on Customer and Company Information cards before submission

Job queue retry pipeline with exponential backoff and a dead-letter log so transient MyInvois API outages don't lose invoices

Permission sets (read-only and full) plus a dedicated setup page so finance and IT roles are cleanly separated

Application Insights telemetry and optional Dataverse/Power BI surfacing of MyInvois status for compliance dashboards

À propos de ce produit

Malaysia's LHDN MyInvois mandate requires every sales document to be transformed into a validated UBL 2.1 e-invoice, submitted through the MyInvois API, and stamped with a unique identifier and validation QR code. Business Central core does not speak MyInvois, and the SST (Sales & Service Tax) regime needs tax codes, exemption handling and statutory reporting that the standard Malaysian functionality does not fully cover.

This is a build-to-order extension, not an instant AppSource download. ECOSIRE builds the app in AL as a per-tenant extension (or a private AppSource-style package where you prefer), then installs and configures it directly on your Business Central Online or on-premises environment. You receive working software on your tenant, configured to your company setup, chart of accounts and document flows.

The extension ships table and page extensions over Sales Invoice, Sales Cr. Memo and posted documents; an event-subscriber pipeline that builds the MyInvois UBL payload on posting; an OAuth2-secured HTTP client that submits to the LHDN MyInvois API and polls validation status; and a job queue entry that retries failed submissions and processes consolidated e-invoices for B2C aggregation. SST tax codes map to BC's VAT posting setup, and statutory data is exported in the formats LHDN expects.

Everything is delivered with permission sets, a configuration page, telemetry to Application Insights, and AL/Power Platform integration points so MyInvois status flows into Power BI or Dataverse if you need it. Because it is built for your tenant, edge cases — multi-company, foreign-currency invoices, self-billed scenarios — are handled against your real data during UAT rather than guessed at.

Ce que vous obtenez

A working AL extension installed on your Business Central tenant (per-tenant extension, or private package if you prefer), version-pinned to your BC release

MyInvois API integration configured with your LHDN credentials, intermediary/ERP system registration and OAuth2 client setup

SST tax codes and VAT posting setup mapped to your chart of accounts and verified against sample transactions

Configuration of permission sets, job queue entries and the setup page for your finance and IT users

A UAT cycle on your real documents (sandbox MyInvois environment first), covering standard, consolidated, self-billed and credit-note flows

Source AL, deployment .app package, setup runbook and an admin handover document, plus a defined support and update period

Pour qui c'est

Finance Controller, Malaysian SME

Needs every sales invoice validated by LHDN MyInvois and SST-02 returns filed correctly, without manually re-keying invoices into the MyInvois portal.

Group IT / ERP Manager

Runs Business Central across one or more Malaysian entities and wants compliance handled inside BC as a maintained extension, not a fragile manual export or spreadsheet bridge.

BC Implementation Partner / Reseller

Needs a reliable Malaysia localization layer to add to a client's Business Central rollout and would rather subcontract the MyInvois/SST build than develop and maintain it in-house.

Foire aux questions sur Malaysia MyInvois & SST Localization for Business Central

Is this an instant download from Microsoft AppSource?

No. This is a build-to-order extension. ECOSIRE builds it in AL, then installs and configures it directly on your Business Central environment as a per-tenant extension (or a private package). You get working, configured software on your own tenant rather than a generic self-install app.

How long does delivery take?

Typical lead time is about 3 to 5 weeks from kickoff, depending on scope (single vs. multi-company, self-billed/import flows, custom statutory reports). It runs in phases: requirements and LHDN/intermediary registration, build, then a UAT cycle against the MyInvois sandbox before we point it at production. You get a firm timeline after the scoping call.

What about ongoing support and updates when LHDN changes the rules?

The price includes a defined support and update window. Within it we fix defects and adjust the extension for LHDN MyInvois schema or SST regulatory changes, and re-test against new Business Central releases. After that window you can move to an annual support and maintenance plan so the extension stays compliant and compatible as BC and MyInvois evolve.

Does it work with Business Central Online and on-premises?

Yes. It is built in AL using supported extension patterns (table/page extensions, event subscribers, the BC HTTP and OData APIs), so it runs on Business Central Online (SaaS) and on supported on-premises versions. We pin the build to your specific BC version and platform during scoping.

Can it handle multiple Malaysian companies and consolidated B2C invoicing?

Yes. The extension is configured per company within your BC environment, with each entity's own TIN, SST registration and MyInvois credentials. A job queue entry aggregates B2C transactions for a period into LHDN-compliant consolidated e-invoices, and multi-company rollout is handled during UAT against your real document flows.
