InvoiceNow Workflow Automation Singapore: Why IRAS Compliance Needs Therefore™ Document Management

InvoiceNow workflow automation Singapore is becoming a board-level question, not just an IT ticket. Following the Ministry of Finance's Committee of Supply 2026 announcement, IRAS confirmed the GST InvoiceNow Requirement will extend to all GST-registered businesses in Singapore by April 2031, with earlier deadlines already active. But InvoiceNow itself only governs how structured invoice data is transmitted to IRAS — it says nothing about how that invoice gets captured, coded, routed for approval, matched against a purchase order, or archived inside your company beforehand. For most Singapore finance teams, that internal workflow is the real compliance gap. This article sets out the InvoiceNow requirement and why Therefore™, the enterprise content management and workflow automation platform available in Singapore through Micrographics Data, is what makes InvoiceNow compliance operationally real rather than a Peppol connection sitting unused.

What IRAS InvoiceNow Requires of Singapore Companies

IRAS InvoiceNow — the GST InvoiceNow Requirement — mandates that GST-registered businesses in Singapore transmit invoice data directly to the Inland Revenue Authority of Singapore via the InvoiceNow network, built on the global Peppol standard and using the PINT-SG invoice format. Introduced by the Infocomm Media Development Authority (IMDA) in 2019, InvoiceNow enables businesses to send and receive invoices in a structured digital format rather than PDF or paper.

The rollout is phased: 1 May 2025 for voluntary early adoption, 1 November 2025 for newly incorporated voluntary GST registrants, 1 April 2026 for all new voluntary registrants, and 1 April 2028 through 1 April 2031 for existing GST-registered businesses, staged by total annual supplies. IRAS will notify existing GST-registered businesses of their specific mandatory implementation date by mid-2026. From 1 April 2026, InvoiceNow adoption also becomes a condition of voluntary GST registration itself. The requirement applies to standard-rated and zero-rated supplies and input tax-claimable purchases, with no minimum transaction threshold — every invoice counts, regardless of size.

The Gap Between "InvoiceNow-Ready" and "InvoiceNow-Operational"

An InvoiceNow-Ready Solution handles transmission — it moves structured invoice data from your business to IRAS and your trading partners over the Peppol network. It does not, by itself, capture a supplier invoice arriving by email or post, route it to the right cost centre owner for approval, flag a mismatched purchase order, or keep an audit trail of who approved what and when. Companies that treat InvoiceNow as a software install rather than a workflow redesign typically end up with a compliant transmission layer bolted onto an unchanged, manual approval process — which means InvoiceNow's efficiency gains never materialise, and the record-keeping obligation IRAS still requires alongside InvoiceNow remains a manual, error-prone task.

This is precisely the layer Therefore™ is built for. As an enterprise content management (ECM) platform ranked #1 in Workflow Automation for multiple years running by Info-Tech Research Group's SoftwareReviews, Therefore™ digitises approval chains and invoice processing end to end — capture, coding, routing, approval, and secure archiving — so the structured data flowing through InvoiceNow reflects a process that is actually automated, not a manual process with a compliance layer stapled on top.

How Therefore™ Facilitates InvoiceNow Compliance in a Singapore Company

Therefore™ is developed by Therefore Corporation, a Canon group company, and is trusted globally by organisations including Uber, LEGOLAND, the NHS, Volkswagen Financial Services, and Scania across finance, healthcare, legal, logistics, manufacturing, and public administration. For a Singapore company preparing for its InvoiceNow mandatory date, three capabilities matter most:

For compliance officers, finance departments, and IT directors in organisations subject to PDPA and MAS TRM obligations, Therefore's ISO 27001:2022 certification and tamper-evident audit trails mean the platform is already built for Singapore's regulatory environment — InvoiceNow readiness sits on top of infrastructure these teams need regardless of the e-invoicing mandate.

Manual Approval Chains vs Therefore-Automated InvoiceNow Workflow

The practical difference shows up at the point of audit, not at the point of invoice receipt.

Where This Goes Next for Singapore Companies

As IRAS's phased deadlines move through 2028 and toward the full 2031 mandate, the Singapore companies with the smoothest transition will be the ones that automated the workflow behind InvoiceNow early, rather than the ones that raced to connect a Peppol Access Point at the last possible date. Therefore™'s AI-powered productivity features and native Microsoft Copilot integration — letting finance teams query and summarise invoice and contract data directly from Word, Excel, Outlook and Teams — point toward where document-driven compliance is heading well beyond the InvoiceNow mandate itself.

Frequently Asked Questions

What does IRAS InvoiceNow require of Singapore companies?

IRAS InvoiceNow, the GST InvoiceNow Requirement, requires GST-registered businesses to transmit invoice data directly to IRAS through the InvoiceNow network, built on the Peppol standard. IRAS has confirmed the requirement extends to all GST-registered businesses by April 2031, phased from a May 2025 soft launch.

Is InvoiceNow just about sending invoices to IRAS?

No. InvoiceNow governs how invoice data is transmitted, but the invoice still has to be captured, coded, routed for approval, matched to a purchase order, and archived internally before that transmission happens. Most Singapore companies find their approval and archiving process, not the Peppol connection itself, is what needs to change.

What is Therefore and how does it support InvoiceNow compliance?

Therefore™ is an enterprise content management and workflow automation platform from Therefore Corporation, a Canon group company. It automates invoice capture, coding, and approval workflows, connects to SAP and Microsoft Dynamics ERP systems, and provides ISO 27001:2022-certified secure archiving with full audit trails, sitting alongside a company's InvoiceNow-ready solution to manage the process end to end.

Does Therefore integrate with our existing ERP system?

Therefore is SAP-certified for S/4HANA and NetWeaver, and certified for Microsoft Dynamics NAV, connecting directly to a company's existing line-of-business systems rather than requiring a separate parallel process for invoice data.

Can Therefore be deployed on-premises or does it require the cloud?

Both. Therefore™ Online is a fully managed cloud deployment, and Therefore™ On-Premises installs on a company's own servers for organisations that require full data sovereignty.

Does Micrographics Data supply and implement Therefore in Singapore?

Yes. Micrographics Data provides local consultation, implementation, training and support for Therefore™ in Singapore, and can pair it with document scanning services to bring legacy paper records into the same workflow.
