What is PINT-SG and how does it differ from PINT-AE?
PINT-SG is Singapore's national customization of the Peppol International (PINT) standard, specifying the data requirements for invoices transmitted through the InvoiceNow network to IRAS. Like PINT-AE for the UAE, PINT-SG extends the core PINT framework with Singapore-specific GST fields, mandatory data elements, and routing requirements aligned with the SG Peppol Directory. Both are national CIUS extensions but differ in their regulatory context, mandatory fields, and tax authority reporting mechanisms.
What is a CIUS in the context of PINT-SG?
A Core Invoice Usage Specification (CIUS) is a localization layer built on top of an international base standard. PINT-SG is a CIUS built on the Peppol International (PINT) base, which itself builds on Peppol BIS Billing 3.0 UBL. CIUS extensions can restrict optional fields to mandatory, add jurisdiction-specific data elements, and impose business rules the base standard does not require. PINT-SG's CIUS rules reflect Singapore's GST invoicing obligations, including supply type classification (standard-rated, zero-rated, exempt) and GST registration number fields.
How does PINT-SG compare to PINT-AE?
PINT-AE (UAE) operates within a 5-corner CTC model where validated Tax Data Documents are reported to Corner 5 (FTA) in near real-time. PINT-SG operates within a 4-corner model where structured invoice data is routed to IRAS via InvoiceNow-accredited Access Points. PINT-AE mandates 15-digit UAE TRN fields; PINT-SG mandates Singapore GST registration numbers and UEN-based Peppol IDs. UAE ASPs require ISO 27001/22301 certifications; Singapore Access Points are accredited by IMDA under different criteria.
Frequently Asked Questions
- Does PINT-SG support both UBL and CII syntaxes?
- The InvoiceNow and PINT-SG framework primarily uses UBL syntax aligned with Peppol BIS Billing 3.0. UBL is the predominant syntax used across Singapore's InvoiceNow-accredited Access Points and ERP integrations.
- Who governs the PINT-SG specification?
- PINT-SG is jointly governed by IMDA (Infocomm Media Development Authority) and IRAS (Inland Revenue Authority of Singapore). IMDA manages the technical network infrastructure and Access Point accreditation, while IRAS manages the GST reporting requirements that the PINT-SG specification must satisfy.
