Open-source project
MyInvois Middleware Gateway
An open-source REST gateway between any business system and the LHDN MyInvois API, free for anyone to use under the MIT licence. It handles sign-in tokens, digital signing, submission, status polling and LHDN rate limits, so a POS, ERP or online shop can issue e-invoices, including the monthly consolidated invoice for B2C sales. It has no screens of its own: it is the engine behind other systems.
