Introduction
InvoiceNow, a nationwide e-invoicing initiative in Singapore, is accelerating the modernisation of finance operations across industries. As structured digital submissions become the new norm, businesses today need to review their invoicing accuracy, data quality, and system readiness. This is where SAP Document and Reporting Compliance (DRC) comes in, enabling businesses to align their SAP systems with Singapore’s digital tax requirements more efficiently.
In this guide, we explore how SAP DRC helps organisations meet these demands and outline the essential steps to get your systems ready.
Understanding Singapore’s InvoiceNow Compliance Framework
From 2026, GST-registered organisations will be required to transmit both customer and supplier invoice information electronically to IRAS using the new InvoiceNow framework under the proposed mandate. This requires invoices to be transmitted through the Peppol network in a structured, machine-readable format that supports automation, accuracy, and end-to-end traceability.
For every invoice submission under this new framework, businesses must:
- Adopt consistent GST tax categories
- Generate valid document identifiers
- Meet IRAS-compliant validation rules
These standards aim to streamline IRAS GST reporting, minimise manual reconciliation, and improve the overall reliability of financial data across the ecosystem.
Meeting these requirements, however, calls for a technology framework that supports automated compliance at scale.
How SAP DRC Presents a Solution
SAP’s Document and Reporting Compliance (DRC) is the central framework for managing statutory reporting, e-documents, and digital tax submissions across different jurisdictions. For Singapore’s InvoiceNow requirements, it serves as the engine that generates, validates, submits, and tracks e-invoices automatically in IRAS-approved formats.
Key Features
Here’s how the DRC system equips businesses with a robust set of tools designed for accuracy, efficiency, and transparency.
1. Automated E-Document Creation
The DRC solution generates IRAS-compliant XML invoices directly from sales, billing, and Point of Sale (POS) systems, as well as petty cash postings. This automation reduces manual data entry, minimises human error, and maintains consistency across all business transactions.
2. Built-In Compliance Rules
GST category mapping, Universally Unique Identifier (UUID) generation, Peppol standards, and IRAS validation rules are embedded into the system. This ensures e-invoicing compliance with Singapore’s regulatory requirements before submission, reducing the likelihood of rejected filings.
3. Centralised Monitoring
The Electronic Document Cockpit provides end-to-end visibility of all outgoing e-invoices through a single interface. Here, users can review XML structures, review submission histories, monitor processing queues, and track IRAS acknowledgement details, making exception handling and audit preparation significantly easier.
4. Real-Time Status Updates
SAP DRC automatically retrieves responses from IRAS and updates the invoice status within the system. This enables finance teams to identify issues quickly, resolve discrepancies, and maintain up-to-date compliance records without manual follow-ups or cross-system checks.
5. Integration with SAP Business Network
This enables seamless Peppol integration and supports automated processing of supplier e-invoices, improving procurement efficiency and strengthening the organisation’s overall e-document workflow.
6. Flexible Deployment Across SAP Landscapes
The DRC solution is available across different SAP solutions for companies. This includes SAP ERP, SAP S/4HANA On-Premise, and SAP S/4HANA Cloud, allowing businesses to adopt the solution regardless of their current system architecture. This flexibility allows organisations to prepare for InvoiceNow without performing major system overhauls or migrations.
How Businesses Should Start Preparing for InvoiceNow
In preparation for InvoiceNow, organisations should align their compliance strategy, system architecture, and user processes. Consider the following steps:
- Monitor Regulatory Announcements: Track Singapore GST changes using SAP’s Regulatory Change Manager.
- Onboard to SAP DRC Cloud Edition: Activate the solution via SAP Business Technology Platform (BTP) and enable both GST InvoiceNow and Peppol Exchange processes.
- Register a Singapore Participant ID: Set up the required ID to authenticate InvoiceNow submissions.
- Configure Connectivity: Establish secure communication between SAP DRC (cloud edition) and your SAP system using cloud connectors and destination mappings.
- Apply SAP Notes and Prerequisites: Implement the necessary components for Peppol frameworks, electronic document processing, and integration.
- Conduct End-to-End Testing: Validate your setup through the InvoiceNow sandbox environment using CorpPass authorisation.
With support from experienced SAP consultants, businesses can ensure that their systems and processes are fully prepared before mandatory adoption begins.
The Roadmap: What Comes Next?
Moving forward, SAP will continue expanding its InvoiceNow capabilities through 2026 and beyond. Upcoming enhancements businesses can expect include:
- Support for supplier invoices involving both GST and withholding taxes
- Enablement for exchanging e-invoices with foreign business partners
- Improvements such as API integrations and GST registration number validation
Further updates will be released through SAP’s Regulatory Change Manager.
