InvoiceNow in Singapore
What is InvoiceNow?
InvoiceNow is Singapore’s nationwide e-invoicing network introduced in 2019 by the Infocomm Media Development Authority (IMDA).
It enables businesses of all sizes to send and receive invoices digitally through a secure, standardised network — helping improve productivity and reduce manual invoice processing.
InvoiceNow operates on the international Peppol e-invoicing standard, allowing invoices to be transmitted directly between different accounting and finance systems — securely, accurately, and without manual re-entry.
Today, more than 60,000 businesses in Singapore are already connected to the InvoiceNow network through approved service providers and Access Points — and adoption continues to grow.
As InvoiceNow expands across industries, cbs Corporate Business Solutions is actively helping businesses understand the requirements, assess readiness, and prepare for adoption — while we work toward becoming an AP and IRSP provider ourselves.
This ensures organisations are not just informed — but practically prepared.
What is the GST InvoiceNow Requirement?
Businesses are required to submit specific invoice data to IRAS using InvoiceNow-Ready solutions connected to the InvoiceNow network.
This requirement covers structured invoice data from common business documents, including:
- Tax invoices
- Credit notes
- Aggregated cash sales
- Aggregated petty cash purchases
The purpose is to standardise how invoice data is transmitted, improve reporting accuracy, and reduce manual processing across GST submissions.
cbs Corporate Business Solutions is actively helping businesses understand these GST InvoiceNow requirements and how to prepare their systems and workflows accordingly.
Roadmap for the GST InvoiceNow Requirement
All GST-registered businesses will soon be required to transmit invoice data to IRAS using InvoiceNow-Ready Solutions via the InvoiceNow network.
Further details will be announced by IMDA to progressively extend mandatory participation to new compulsory GST registrants and the remaining GST-registered businesses.
Newly incorporated companies that voluntarily apply for GST registration are required to send invoice data to IRAS using InvoiceNow-Ready Solutions.
All new voluntary GST registrants are required to start submitting invoice data to IRAS using InvoiceNow-Ready Solutions.
How InvoiceNow Works
InvoiceNow is built on the Peppol e-invoicing model, where invoices move securely from supplier to buyer through certified network providers — instead of being sent as PDFs or emails.
In the standard four-corner model, invoice data travels system-to-system through Peppol Access Points. This removes manual re-entry and allows structured invoice data to flow directly between both parties’ accounting systems.
Under GST InvoiceNow requirements, the model extends to a five-corner flow. In addition to reaching the buyer, structured invoice data is also transmitted through InvoiceNow-Ready solutions to IRAS for GST reporting purposes.
This extended flow enables:
- Structured invoice data submission
- Reduced manual GST reporting work
- Better data accuracy
- Faster validation and review
- More consistent compliance processes
cbs Corporate Business Solutions is aligning our InvoiceNow enablement capabilities with emerging Peppol International (PINT) standards to support broader interoperability and cross-border e-invoicing readiness.
While Singapore InvoiceNow adoption focuses on domestic structured invoice exchange and GST reporting, PINT developments support future international invoice compatibility across Peppol jurisdictions.
For medium and large enterprises, standards alignment helps ensure that InvoiceNow investments remain scalable, interoperable, and future-ready.
Key Invoice & GST Reporting Challenges for Businesses
As invoice volumes grow and GST reporting requirements evolve, many organisations find their current invoicing and data submission processes difficult to scale reliably. Fragmented systems and manual controls can create cost, risk, and operational bottlenecks across the business.
InvoiceNow Benefits for Businesses
— especially at higher transaction volumes.
Structured system-to-system exchange minimises document tampering risk and improves data integrity controls compared to unstructured invoice files and manual transfers.
Standardised invoice data improves traceability and validation, helping businesses respond more efficiently to GST checks and compliance reviews.
System-level invoice transmission enables better tracking of invoice delivery and receipt status across trading partners, improving process transparency.
