InvoiceNow Singapore: E-Invoicing, Grants and GST Compliance Guide
InvoiceNow is Singapore’s nationwide e-invoicing network that enables businesses to send and receive structured electronic invoices through the Peppol network. Unlike traditional PDF invoices sent by email, InvoiceNow allows invoice information to move directly between compatible accounting systems, reducing manual data entry and improving the efficiency of accounts payable and receivable processes.
For Singapore businesses, InvoiceNow has become increasingly important as the government progresses towards digital tax administration and the phased implementation of the GST InvoiceNow Requirement.
What Is InvoiceNow?
InvoiceNow is Singapore’s national e-invoicing framework based on the international Peppol standard. It allows businesses to exchange invoices electronically between finance and accounting systems in a structured format.
The system can help businesses:
- Reduce manual invoice processing
- Minimise data-entry errors
- Improve invoice tracking
- Streamline accounts payable and receivable
- Speed up invoice processing
- Improve the accuracy of accounting records
- Prepare for Singapore’s evolving GST reporting requirements
InvoiceNow is different from simply emailing a PDF invoice. A PDF still generally requires the recipient to manually extract and enter information into its accounting system. InvoiceNow is designed to transmit structured invoice data directly between connected systems.
Are InvoiceNow Grants Still Available?
Businesses may come across older online information about InvoiceNow grants and incentives, including the InvoiceNow Transaction Bonus and LEAD Connect and Transact grants.
These incentives were introduced by IMDA to encourage adoption of the InvoiceNow network.
Current eligibility, implementation requirements and available support should be checked against the latest information from IMDA and IRAS.
InvoiceNow and the GST InvoiceNow Requirement
InvoiceNow is becoming increasingly relevant to GST compliance in Singapore.
The GST InvoiceNow Requirement is being introduced progressively. Under the current implementation schedule, newly incorporated companies that voluntarily register for GST within the applicable period were brought into the requirement from 1 November 2025. From 1 April 2026, the requirement applies to all new voluntary GST registrants, regardless of incorporation date or business structure. Further phases are scheduled for existing GST-registered businesses based on their annual supplies.
This means businesses should consider their accounting and invoicing systems early rather than waiting until their applicable compliance date.
How Does InvoiceNow Work?
The basic process is straightforward:
- Select an InvoiceNow-ready solution
Businesses need an accounting or invoicing solution that can connect to the InvoiceNow network.
- Register for InvoiceNow
The business can work with an appropriate InvoiceNow-ready solution provider or access point provider to establish its connection and obtain the necessary Peppol identification.
- Connect InvoiceNow with your accounting system
For businesses using cloud accounting platforms such as Xero, InvoiceNow can be integrated into the existing finance workflow.
- Send and receive e-invoices
Once activated, businesses can send structured invoices to customers and receive electronic invoices from suppliers through the InvoiceNow network.
- Prepare for GST data transmission
Where applicable, the InvoiceNow solution can support the transmission of relevant invoice data to IRAS in accordance with the GST InvoiceNow Requirement.
InvoiceNow with Xero
Businesses already using Xero may be able to connect their accounting workflow to InvoiceNow.
With a properly configured setup, sales invoices can be transmitted through the InvoiceNow network while incoming e-invoices can flow into the accounting system for review and processing.
WLP provides guidance on InvoiceNow and Xero integration for Singapore businesses. WLP’s InvoiceNow resources explain how businesses can connect Xero to InvoiceNow, register through the relevant solution and send and receive e-invoices using the Peppol network.
Why Should Singapore Businesses Adopt InvoiceNow?
Reduce manual work
InvoiceNow can reduce the need to manually re-enter invoice information into accounting systems.
Improve data accuracy
Structured digital invoice information can reduce common transcription and data-entry mistakes.
Streamline accounting workflows
Connecting invoicing with accounting software can make it easier for finance teams to manage accounts receivable and accounts payable.

Digital transmission provides businesses with a more structured process for tracking invoices and maintaining accounting records.
Prepare for regulatory changes
Early adoption gives businesses more time to configure their accounting systems and establish appropriate processes before their applicable GST InvoiceNow compliance deadline.

An accounting firm can assist with areas such as:
- Accounting system setup
- Xero configuration
- InvoiceNow onboarding
- Bookkeeping workflow adjustments
- GST treatment and accounting processes
