LHDN MyInvois compliance
Connect your ERP, POS, or legacy database directly to LHDN MyInvois — automated field mapping, PKI signing, and high-volume submission without staff leaving their primary system.
Malaysia e-invoice API integration connects your business systems to LHDN MyInvois so invoices validate automatically. e-Invoice middleware Malaysia is the bridge that maps ERP or POS data, signs payloads, and submits UBL documents — without re-keying into the portal. Xantec builds custom middleware when volume, privacy, or complex tax logic outgrow ready-made SaaS.
We help Malaysian organisations that need automated MyInvois submission from systems they already run — not another manual portal workflow.
Reviews and anonymised outcomes matter more than slogans. Here is how we keep checkout fast while finance stays LHDN-ready.
E-invoicing
Retail and wholesale invoices had to meet LHDN submission rules while POS lanes stayed sub-second. We introduced a queue-backed submission layer, human-readable rejection reasons for finance, and reconciliation exports that matched the accounting team’s existing month-end process.
A clear path from discovery to production — you own the bridge; we engineer and support it.
Map schemas, tax rules, and document types to LHDN UBL fields before any production write.
API or flat-file bridge with signing, retries, and finance-visible rejection handling.
MyInvois sandbox validation, cut-over plan, and hypercare so month-end is not a surprise.
Indicative custom programme fees (build only, excludes third-party licences): focused ERP or POS connectors often land around RM 55,000 – RM 150,000; multi-system or high-volume platform programmes commonly RM 120,000 – RM 350,000+. Ready-made SaaS (for example einvoice-online.my) suits lower volume with subscription pricing. Quotes always follow an audit of volume, schema complexity, and on-premise vs cloud requirements.
Portal vs API integration
For Malaysia e-invoice API integration, the right submission path depends on volume and complexity. The MyInvois Portal is free for low volume; direct API integration (via middleware) is the standard when ERP or POS throughput matters.

The definition
An LHDN e-invoice integration service connects your systems to MyInvois so transactions are validated digitally via API. While many businesses adopt basic plug-and-play portals, high-volume operations need custom Malaysia e-invoice API integration built around their ERP or POS.
It connects directly into your existing SAP, Oracle, Microsoft Dynamics, AutoCount, SQL Accounting, or bespoke software. Invoices are generated and validated without staff leaving their primary software interface.
It programmatically maps your internal complex database schemas to the strict 55+ mandatory and optional fields required by the LHDN UBL 2.1 XML/JSON format.
Handles real-time OAuth 2.0 token generation and digital certificate (PKI) signing of every invoice payload milliseconds before transmission to LHDN servers.
Data emission
Digital signing…
We don't just send standard invoices. Our custom integration is engineered to handle the full spectrum of LHDN document types required across all Malaysian business models.
For B2B and B2G transactions requiring full buyer TIN and SST metadata routing.
Crucial for retail & POS. We aggregate high-volume B2C daily receipts into automated, monthly LHDN batch submissions.
Automated negative value submissions linked via the original validated invoice UUID for seamless returns processing.
Full support for upward adjustments and refund documentation mapped to strict LHDN classification codes.
Our e-Invoice SDK and custom middleware bridge LHDN MyInvois with Malaysian accounting stacks and enterprise ERPs — including AutoCount API integration and SQL Account API programmes. Need broader connectivity beyond e-invoice? See our API integration services in Malaysia.
The Xantec advantage
Many service providers offer ready-made portals (like our own simplified einvoice-online.my) intended for small businesses. However, custom integration is designed specifically for high-volume enterprises, manufacturing plants, and franchised retail chains.
When you opt for custom development, you retain 100% data privacy. Your sensitive financial data does not sit on a third-party SaaS provider's server; it travels encrypted directly from your private database to the LHDN portal.
Furthermore, custom solutions allow you to bypass ongoing transactional subscription fees. You own the bridge, ensuring compliance without incurring a "tax" on every invoice you generate as your business scales.
We operate with the rigorous precision required for financial middleware. From isolated sandbox environments to zero-downtime cutovers.
We analyze your database schemas, internal taxonomy, and tax structures to map them against LHDN's strict JSON requirement parameters.
We write the custom connectivity layer—be it an API wrapper in Node.js, C#, or Java, or an automated flat-file parsing service for legacy systems.
Before touching live data, we execute high-volume simulated submissions to the LHDN SDK MyInvois Sandbox environment, refining error-handling algorithms.
Smooth transition to production under LHDN SLA environments, accompanied by centralized dashboard logs within your ERP for easy monitoring.
Digital tax transformation
In Malaysia, e-Invoicing is a structured digital transaction record (typically XML or JSON) validated through LHDN MyInvois — not a PDF emailed to a buyer. Every validated document carries a unique identifier and government digital signature.
Manual portal entry works for low volume. When your ERP or POS issues invoices at scale, you need Malaysia e-invoice API integration (middleware) so data maps, signs, and submits automatically without double-entry.
Compliance roadmap
Mandatory cycles for businesses above earlier turnover thresholds are complete. Enterprise systems across Malaysia are already live on MyInvois via portal or API.
Mandatory e-invoicing expanded to remaining taxpayers. Organisations still on manual entry should evaluate API or middleware before volume and rejection risk climb.
LHDN's RM1 Million annual revenue threshold exempts businesses below that amount from mandatory e-invoicing. Above the threshold, compliant submission via MyInvois remains required.
Active rule: consolidation cap
Taxpayers may consolidate B2C receipts into monthly e-Invoices. Any single transaction exceeding RM10,000 is excluded from consolidation and needs an individual e-Invoice — a common driver for ERP e-invoice integration Malaysia programmes.
Xantec bridge capabilities
Our e-invoice middleware Malaysia layer is the bridge between your operations and LHDN — translating ERP/POS data, signing payloads, and submitting to MyInvois so finance teams do not re-key invoices.
Automate the extraction of invoice data from your ERP, POS, or legacy SQL database. Eliminate human error and repetitive tasks instantly.
Every invoice is pre-validated against LHDN's 55-field metadata schema before submission, designed for high acceptance rates and clear rejection handling when data is incomplete.
Handle thousands of transactions simultaneously. Ideal for high-volume retail, wholesale, and service providers requiring consolidated invoicing.

Malaysia e-invoice API integration is the automated connection between your business systems and LHDN MyInvois. Instead of typing invoices into the portal, middleware maps your ERP or POS data to the required UBL fields, signs each payload with your digital certificate, and submits it for validation in real time.
e-Invoice middleware Malaysia is the software bridge between your operational systems and LHDN. It handles data translation, OAuth tokens, PKI signing, retries, and logging so finance teams keep working in their ERP while MyInvois receives compliant documents.
Cost depends on system complexity, document volume, and whether you need custom logic (consolidated B2C, credit notes, multi-branch POS). Indicative custom build fees often range from about RM 55,000 for a focused connector to RM 120,000 – RM 350,000+ for multi-system programmes, plus optional support retainers. Ready-made portals suit lower volume with subscription pricing. We quote after an audit — not a one-line price that ignores schema and rejection handling.
Yes. Our ERP e-invoice integration Malaysia programmes cover SAP, Microsoft Dynamics, Odoo, Oracle, AutoCount, SQL Accounting, Yonyou, custom ERPs, and multi-branch POS. For dedicated AutoCount or SQL Account middleware (beyond e-invoice), see our AutoCount API and SQL Account API developer pages. Scope depends on your schema, tax rules, and whether you need on-premise or cloud middleware.
An LHDN e-invoice integration service designs, builds, and supports the MyInvois connection end to end — discovery, middleware or API development, sandbox testing, go-live, and rejection handling — so your organisation stays compliant without changing how staff create invoices day to day.
Unlike ready-made middleware that forces you to change your workflow to fit their portal, a custom integration is built natively into your system. It supports complex manufacturing rules, multi-branch POS consolidated invoicing, maintains data privacy on-premise if required, and requires no monthly third-party subscription.
Yes. If your AS400, older Oracle database, or legacy custom software cannot handle modern REST APIs, we design a custom flat-file bridge. This bridge securely reads your scheduled data exports (CSV/XML), converts them to the LHDN UBL format, signs them with your digital certificate, and submits them automatically.
Yes. Our custom middleware manages the encryption payload. We securely store and use your LHDN-issued digital certificate to sign every invoice before it reaches MyInvois, supporting non-repudiation requirements. A PDF alone is not an e-invoice — LHDN requires the structured fields and government validation signature.
Our custom integrations include robust state-management and retry queues. If an invoice is rejected by LHDN (e.g., due to an invalid buyer TIN), it is flagged immediately within your own ERP's dashboard or via email notification with the exact API error translated into human-readable instructions.
