E-Invoice Submission is an ML IT Partners extension for Dynamics 365 Business Central that submits your posted journal entries to LHDN for e-Invoicing compliance, without leaving the system where they were posted. Malaysia’s Inland Revenue Board has made electronic invoicing mandatory in phases since 2024, and the mandate now reaches every business with an annual turnover above RM1 million, with smaller businesses free to adopt it voluntarily.
Under e-Invoicing, an invoice is no longer a document a business prints and files for itself. LHDN must validate it first through the MyInvois platform: submissions are checked against the taxpayer registry for the seller’s and buyer’s TINs, verified against mandatory data fields and validation rules, and returned with a Unique Identifier Number (UIN) and QR code that buyers can use to confirm an invoice is genuine. For a business posting hundreds of documents a month from Business Central, keying each one into the MyInvois portal does not scale, and invoices issued without LHDN validation leave tax compliance exposed.
E-Invoice Submission brings that validation into the accounting workflow. Posted entries are mapped to the fields LHDN checks, submitted through the MyInvois API, and tracked until they come back validated, with the UIN, QR data, and status stored alongside the original entries as audit-ready evidence. Consolidated submissions keep high-volume consumer sales manageable within LHDN’s rules, and corrections and cancellations are handled within the 72-hour window LHDN allows after validation. Alongside the EFT File Export add-on, it completes ML IT Partners’ Business Central finance toolkit: payments and e-invoices both run from one environment, with no portals and no re-keying.
What’s included
- One-click submission of posted journal entries from Business Central to LHDN, replacing manual entry in the MyInvois portal
- Automatic mapping of posted entries to the data fields LHDN validates, including seller and buyer TINs, business registration numbers, amounts, taxes, and references, with completeness checks that catch missing data before submission
- Secure submission through the MyInvois API with automated authentication, plus batch handling and job-queue scheduling for high-volume posting periods
- Live status tracking for every document, showing submitted, validated, and rejected states, so rejections are caught and corrected promptly instead of at audit time
- The LHDN-issued UIN and QR code data recorded against each validated document, ready for buyer-facing invoices that customers can verify
- Consolidated e-invoice support for eligible B2C sales, aggregating many small consumer transactions into compliant submissions without an individual invoice for every sale
- Credit notes, debit notes, and refund notes handled alongside sales invoices, including cancellations and corrections within the 72-hour window LHDN allows
- A complete audit trail of submissions, LHDN responses, and validation records held with the source entries, ready for any LHDN audit
How ML IT Partners can help
ML IT Partners is a certified Microsoft Dynamics partner established in 1998, with close to three decades of experience implementing ERP and finance solutions for Malaysian businesses. An e-Invoicing project with ML IT starts with readiness. Their consultants confirm which requirements apply to your business: the phase of the mandate based on your turnover and the document types you will issue. They then guide you through MyInvois registration and the API credentials the extension needs, and verify that the master data LHDN checks, such as TINs, business registration numbers, and customer details, is complete and consistent in Business Central.
Their team then configures the extension around your posting practices, tests submissions against LHDN’s sandbox environment before anything goes live, and trains the finance staff who post and reconcile every day. Because LHDN continues to revise its e-Invoice guidelines and validation rules, ML IT keeps the extension and its configurations current as those changes land, and stays available for day-to-day support. That is how compliance is maintained: through steady updates inside your Business Central environment, not rework under pressure at audit time.
