Singapore E-Invoicing: InvoiceNow, Peppol, and GST Compliance Timeline for Businesses and SAP Users

• Singapore adopted the Peppol e-invoicing framework in 2018 and launched the InvoiceNow network in 2019 for voluntary B2B and B2G e-invoicing.
• The GST InvoiceNow Requirement begins May 2025, requiring certain GST-registered businesses to transmit invoices to IRAS via InvoiceNow.
• The rollout is phased: voluntary submission starts May 2025, mandatory for new GST-registered companies (less than 6 months old) from November 2025, with further requirements from April 2026.
• InvoiceNow uses the SG Peppol BIS Billing 3.0 standard, supporting compliance and integration with SAP ECC and S/4HANA systems.
• Understanding the timeline and requirements is crucial for legal compliance with Singapore’s evolving digital invoicing regulations.
