Quick guide
InvoiceNow e‑invoicing in Singapore
What is e-invoicing?
E‑invoicing is the automated electronic creation and exchange of invoices through networks like PEPPOL (the backbone of Singapore's InvoiceNow initiative). Unlike PDFs or email attachments, the structured format minimises errors, speeds up delivery, and keeps you compliant without the manual work.
IRAS e-invoicing mandate
The Inland Revenue Authority of Singapore (IRAS) and IMDA have mandated InvoiceNow adoption for GST-registered businesses, to reduce errors, combat fraud, and modernise Singapore's tax infrastructure.
Key dates for implementing e‑invoicing in Singapore
From November 1, 2025, newly incorporated companies that registered for GST were required to adopt InvoiceNow. From April 1, 2026, this requirement extends to all new voluntary GST registrants.

A PDF invoice is a digital version of a paper invoice—the recipient still has to enter the data manually. An e-invoice is transmitted as structured data through InvoiceNow, flowing directly into the recipient's accounting system. This eliminates re-keying, reduces errors, and speeds up payment.
PEPPOL is an international e-invoicing network standard. InvoiceNow is Singapore's national e-invoicing network, built on the PEPPOL framework. Being on InvoiceNow means you can exchange invoices with any other PEPPOL-connected business globally.
No. E-invoicing handles the transmission of invoice data between businesses. You still need to file your GST F5 returns with IRAS separately. That said, because your invoice data is already structured and accurate, preparing your return becomes much easier.
E-invoices via InvoiceNow can only be sent to recipients who are also registered on the network. If your customer isn't on InvoiceNow, you can still send them a regular invoice. Zoho Books supports both—it will push an e-invoice when the recipient is on the network, or let you send a standard invoice otherwise.
Zoho Books tracks the transmission status of every e-invoice—pending, successfully pushed, or failed. If a transmission fails, you'll be notified within the platform so you can resend or follow up. You always have a clear view of what's been delivered and what hasn't.
