InvoiceNow Singapore: early adoption pays off for businesses
Singapore, 29 June 2026 – Singapore’s tax authority IRAS is urging businesses not to wait before switching to InvoiceNow, Singapore’s Peppol-based e-invoicing network. GST-registered businesses will be required to send invoice data to IRAS via InvoiceNow, in a phased rollout running through 2031, with a full mandate from April 2028. Businesses that switch early qualify for grants and free starter packages.
What is InvoiceNow Singapore?
InvoiceNow is Singapore’s national e-invoicing network and, like the Peppol-based systems Peppol.nu regularly covers for European countries, is built on the Peppol standard. Invoices are exchanged digitally between buyer and seller in structured form, largely eliminating manual data entry. GST-registered businesses will be required to report their invoice data to IRAS through this network, with different groups of businesses becoming subject to the mandate at different points, 2028 marking the full mandate and 2031 the end of the phased rollout.
Why IRAS recommends starting now
Businesses that switch early benefit from practical advantages that will no longer be available after the mandatory start date: grants and free starter packages make the first step cheaper, and early implementation leaves more time to test systems calmly rather than under time pressure just before the deadline. IRAS also expects InvoiceNow to improve interoperability between businesses, reduce manual processes, and speed up GST audits and refunds, since data arrives already structured and validated.
For smaller businesses, low-cost ready-made solutions are available, while larger organisations mainly need to plan time for ERP integration, testing and internal process changes. That preparation time is exactly what IRAS is targeting with its call for early adoption.
What this means for international trading partners
For Dutch and Belgian businesses with customers, suppliers or an establishment in Singapore, this is relevant news: because InvoiceNow is built on Peppol, an existing Peppol connection already used for European obligations can potentially also be used towards Singapore, provided the chosen Peppol Service Provider is active there. This fits a pattern that is becoming increasingly visible: from Oman to Singapore, countries outside Europe are choosing Peppol as the technical foundation for their e-invoicing mandate, further increasing the return on a robust Peppol connection for internationally active businesses.
More on how Peppol is being rolled out globally and what this means for businesses invoicing internationally is available in Peppol PINT global: how Peppol is expanding from European standard to worldwide network.
In short, the InvoiceNow Singapore mandate for GST-registered businesses is coming regardless, but businesses that get in early save both cost and time compared with waiting until just before the deadline.
