How to Reconcile GST InvoiceNow Submissions in Xero (Singapore) – A Complete Guide
As Singapore continues its digital tax transformation, GST InvoiceNow is becoming an essential compliance requirement for GST-registered businesses. If you’re using Xero with InvoiceNow, reconciling your GST InvoiceNow submissions ensures that every invoice and transaction sent to the Inland Revenue Authority of Singapore (IRAS) has been successfully transmitted and recorded.
In this guide, we’ll explain how to reconcile GST InvoiceNow submissions in Xero, common submission statuses, and best practices to keep your business compliant.
What Is GST InvoiceNow?
GST InvoiceNow is an initiative introduced by IRAS that allows businesses to transmit invoice transaction data electronically through the InvoiceNow (Peppol) network. Instead of manually reporting invoice information, businesses using InvoiceNow-ready accounting software like Xero can submit transaction data directly to IRAS.
The requirement is being introduced in phases, with mandatory adoption for certain newly GST-registered businesses.
Why Reconciling GST InvoiceNow Submissions Is Important
Reconciling your GST InvoiceNow submissions helps you:
- Confirm invoices were successfully transmitted to IRAS.
- Detect failed or pending submissions early.
- Maintain accurate audit records.
- Reduce GST reporting errors.
- Stay compliant with Singapore’s evolving GST requirements.
Regular reconciliation also makes future GST filing and compliance reviews much smoother.
Method 1: Reconcile Using Xero History & Notes Report
Xero records every GST InvoiceNow submission within the History & Notes report.
Steps:
- Open Accounting in Xero.
- Select History & Notes.
- Choose the reporting period.
- Search for GST InvoiceNow.
- Review all submission activities.
Each successful submission includes:
- Submission confirmation
- Transmission acknowledgement
- Unique GST InvoiceNow Transmission ID
This report can also be exported to Excel or PDF for internal documentation or audit purposes.
Method 2: Check the Invoici eInvoices Dashboard
Businesses connected to InvoiceNow through Invoici can also monitor submissions from the eInvoices Dashboard.
The dashboard displays the real-time status of every transaction sent to IRAS.
Common statuses include:
Submitted
The transaction has been successfully transmitted to IRAS.
In Processing
The submission is still being processed.
Failed
The submission was unsuccessful due to validation or data issues.
Users can review the error message, correct the transaction, and resubmit it.
Not Submitted
The invoice has not yet been transmitted.
Not a Tax Invoice
Transactions using the No Tax code are not submitted to IRAS.
Common Reasons GST InvoiceNow Submissions Fail
Some of the most common causes include:
- Missing or incorrect Unique Entity Number (UEN)
- Invalid customer information
- Incorrect GST details
- Missing mandatory invoice fields
- Invoice validation errors
- Connectivity or transmission issues
Resolving these issues promptly helps avoid delays in GST reporting.
Best Practices for GST InvoiceNow Reconciliation
To maintain compliance:
- Reconcile submissions regularly instead of waiting until GST filing.
- Review failed transactions immediately.
- Keep customer UEN and GST registration details up to date.
- Save exported reconciliation reports for audit purposes.
- Ensure staff understand InvoiceNow submission workflows.
- Monitor submission statuses through both Xero and Invoici.
Following these practices reduces manual corrections and improves reporting accuracy.
