About this Product

This is a build-to-order AL extension that brings full LHDN MyInvois compliance into your existing Microsoft Dynamics 365 Business Central environment. ECOSIRE designs, builds, installs, and supports it as a per-tenant extension on your BC online (or on-premises) tenant — there is no instant AppSource download. You buy the build; we deliver a working, tested extension wired into your posting and document flows.

The extension hooks into Business Central's sales and purchase posting routines through AL event subscribers, so when you post a Posted Sales Invoice, Credit Memo, or self-billed purchase document, it generates a compliant UBL 2.1 document mapped to the LHDN MyInvois data model with Peppol PINT-MY support. Documents are submitted to the MyInvois API for validation and clearance; the returned Unique Identifier, validation status, and the LHDN QR code are written back onto table extensions and surfaced on page extensions of your invoice cards and list pages.

It covers the realities of the phased Malaysian mandate: standard B2B invoices, self-billed e-invoices for foreign suppliers and specific transaction types, and consolidated e-invoices for aggregated B2C sales submitted within the monthly window. Supplier and buyer TIN, BRN/MyKad/passport identifiers, SST registration, and MSIC code fields are validated before submission to reduce rejections.

Submission runs through the BC Job Queue for ret[ries and batch processing, with full status tracking, error capture, and resubmission from a dedicated MyInvois management page. A QR-coded, human-readable visual invoice (PDF) is produced for sharing with buyers. Permission sets, telemetry, and an audit trail of every API call are included. We scope to your CoA, document types, and which mandate phase your turnover places you in.

Frequently Asked Questions about Malaysia MyInvois (LHDN) E-Invoicing for Business Central

How long does delivery take, and is this an AppSource download?

This is build-to-order, not an instant AppSource install. After a short scoping call we typically deliver in about 2 to 4 weeks depending on your document types, mandate phase, and whether self-billed and consolidated scenarios are in scope. ECOSIRE builds the AL extension, installs it as a per-tenant extension on your sandbox, validates it against the LHDN MyInvois pre-production environment, then cuts over to production with you.

What ongoing support and updates are included after go-live?

The one-time build includes a hypercare period after go-live for fixes and adjustments. LHDN and Peppol PINT-MY rules evolve through the phased mandate, so we offer an optional ongoing support and maintenance arrangement that covers MyInvois API changes, schema updates, and Business Central version upgrades. We discuss the maintenance option during scoping so you are never left non-compliant after a regulatory change.

Does it work with both Business Central online and on-premises?

Yes. The extension is built in AL and installed as a per-tenant extension, which works on Business Central online (SaaS) and on-premises or private-hosted deployments. We confirm your exact BC version during scoping and target the build to it, since AppSource-style runtime constraints and event signatures vary by release.

How does it handle self-billed and consolidated e-invoices?

Self-billed e-invoices are generated from posted purchase documents for applicable cases such as foreign suppliers, and consolidated e-invoices aggregate qualifying B2C sales into a single submission within the LHDN monthly window. Both are configured to your transaction patterns during the build and tested in the MyInvois sandbox before production.

What happens if a submission is rejected or the MyInvois API is down?

Submission runs asynchronously through the Business Central Job Queue with retry on transient failures. Validation errors and LHDN rejections are captured with their messages on a dedicated MyInvois management page, where your team can correct the source data and resubmit. Every API request and response is logged for audit, and cancellation/rejection actions are supported within LHDN's allowed time limits.

Will it disrupt our existing Business Central posting process?

No. The extension uses AL event subscribers on the standard sales and purchase posting routines, so your team posts invoices exactly as they do today. E-invoicing fires automatically in the background, and the resulting UUID, status, and QR code appear directly on your existing invoice cards and list pages.
