InvoiceNow Xero Setup Guide (Singapore) – Complete Step-by-Step for Businesses
As Singapore moves towards full digitalisation of invoicing, InvoiceNow (Peppol e-invoicing) is becoming essential for businesses using accounting software like Xero. With upcoming GST InvoiceNow requirements from 2025–2026, companies must prepare early to stay compliant and efficient.
This guide explains how to set up InvoiceNow with Xero, its benefits, and how professional support like WLP can help streamline the process.
What is InvoiceNow and Why It Matters
InvoiceNow is Singapore’s nationwide e-invoicing network that allows businesses to send invoices directly from one accounting system to another—without emails or PDFs.
Instead of manual entry, invoices are transmitted via the secure Peppol network, reducing errors and speeding up payments.
Key Benefits:
- Faster invoice processing and payments
- Reduced manual data entry
- Improved accuracy and compliance
- Lower administrative costs
Many businesses can save time and operational costs while improving cash flow.

Before starting, ensure you have:
- Active Xero subscription
- Company UEN (Unique Entity Number)
- CorpPass access for authorisation
- Singpass app for verification
These are required to register your business on the InvoiceNow network.
Step-by-Step: How to Set Up InvoiceNow in Xero
Step 1: Connect Xero to InvoiceNow Provider
Log in to an integration platform like Invoici and select Connect to Xero.
Step 2: Authorise Access
Choose your Xero organisation and allow permissions for integration.
Step 3: Verify Business Information
Check your company details and ensure your UEN is correctly entered.
Step 4: Confirm Registration Details
Review and confirm all information before proceeding.
Step 5: Complete CorpPass / Singpass Authorisation

Step 6: Activation Confirmation
Once completed, your business will receive a Peppol ID and InvoiceNow email address.
This setup enables your business to send and receive e-invoices directly through Xero.
How Sending and Receiving Invoices Works
Sending Invoices

This eliminates repetitive data entry and reduces errors significantly.
