What is MyInvois e-invoicing?
MyInvois is Malaysia's e-invoicing system run by LHDN (Inland Revenue Board). Invoices are submitted to LHDN for validation before being shared with the buyer, receiving a Unique Identifier Number and a QR code that links to the validated record. The mandate is phased by annual turnover — starting August 2024 with businesses above RM100 million and extending to progressively smaller bands through 2025–2026, with the smallest businesses exempt below a threshold.
MyInvois phased rollout (summary)
| Phase start | Annual turnover band |
| 1 Aug 2024 | Above RM100 million |
| 1 Jan 2025 | RM25–100 million |
| 1 Jul 2025 | RM5–25 million |
| 1 Jan 2026 | RM1–5 million |
Bands and relaxation periods have been adjusted by LHDN announcements — confirm your obligation date on the MyInvois portal.
SST and e-invoicing together
Malaysia's Sales & Service Tax must be treated correctly per line item while documents flow through MyInvois validation — including self-billed e-invoices for certain purchases and consolidated e-invoices for B2C sales where permitted. PeppyBooks handles SST calculation, the MyInvois validation flow, credit/debit notes and consolidated submissions from the same billing engine that runs your books and stock.
