2. Is E-Invoicing secure?

Security and integrity of the messages exchanged through the PEPPOL network (E-Invoice Transport Infrastructure) relies on encrypted transport using SSL and additionally a Public Key Infrastructure (PKI). This ensures that only parties with valid digital certificates can communicate on the PEPPOL network. When any Access Point or SMP providers sign the PEPPOL Transport Infrastructure Agreement with IMDA they can apply for a PEPPOL Digital Certificate.

This certificate contains the key cryptographic information for validating their communications on the PEPPOL network. This ensures only known and trusted providers have access to the E-Invoice Transport Infrastructure.

No, under current regulation IRAS is not able to access your invoice. However, you do need to comply with any IRAS tax regulations as per normal. How much does it cost? This is dependent on the Access Point operator that you choose.
