LHDN & PeppolSync Implementation FAQ

Q1: What is PeppolSync and how does it connect to Malaysia LHDN MyInvois?

PeppolSync is an enterprise e-invoicing middleware that seamlessly bridges your existing ERP or accounting system (Odoo, SAP, Oracle NetSuite, Microsoft Dynamics, or custom API) with Malaysia's LHDN MyInvois portal and the international Peppol network. It automates validation, digital signing, submission, and QR code generation in real time with zero disruption to daily workflows.

Q2: What is the difference between API integration via PeppolSync vs manual LHDN portal submission?

Manual submission requires staff to re-enter invoice data line-by-line into the LHDN MyInvois portal, causing high operational overhead and risk of human errors. PeppolSync provides direct automated API transmission straight from your ERP upon invoice validation, generating LHDN UUIDs and compliant QR codes within seconds.

Q3: When are the mandatory LHDN E-Invoicing deadlines in Malaysia?

Malaysia's LHDN e-invoicing implementation is phased by annual turnover: Phase 1 (Revenue > RM100M) began August 1, 2024; Phase 2 (Revenue RM25M - RM100M) started January 1, 2025; and Phase 3 (all other taxpayers and MSMEs) is mandated from July 1, 2025 onwards.

Q4: Which ERP and accounting systems are compatible with PeppolSync?

PeppolSync natively integrates with Odoo ERP, SAP ECC & S/4HANA, SAP Business One, Oracle NetSuite, Microsoft Dynamics 365 Business Central, AutoCount, SQL Account, and any custom proprietary ERP via secure RESTful JSON/XML APIs.

Q5: Does PeppolSync support consolidated e-invoices, credit notes, and debit notes?

Yes. PeppolSync fully supports all mandatory LHDN document types including standard commercial invoices, credit notes, debit notes, refund notes, self-billed invoices, and consolidated monthly e-invoices compliant with LHDN rules.

Q6: How does PeppolSync handle multi-company and multi-currency transactions?

PeppolSync is architected for multi-tenant and multi-company setups. It manages distinct Tax Identification Numbers (TIN), Business Registration Numbers (BRN), MSIC codes, and automatic foreign exchange currency conversions required for international transactions.

Q7: What is the Peppol network and why is it beneficial for Malaysian businesses?

Peppol (Pan-European Public Procurement On-Line) is a globally recognized standard for secure electronic document exchange. PeppolSync's MDEC-accredited Peppol capability allows Malaysian businesses to seamlessly trade and exchange digital invoices with global partners across Singapore, Europe, Australia, and New Zealand.
