Ready to Make the Switch to InvoiceNow? Here is How to Do It in ABSS
With IRAS officially rolling out the mandatory GST InvoiceNow requirements, many business owners are realizing it is time to connect their accounting software to the Peppol network.
If you are using ABSS Accounting Connect or ABSS Premier Connect (Singapore), the good news is that the integration is already built into your system. You do not need a complex IT overhaul to get started.
Here is the exact, step-by-step process to activate (or deactivate) your InvoiceNow connection directly from your ABSS Connect portal.
Phase 1: Activating InvoiceNow (Connecting to the Network)
Getting connected is straightforward. You will handle this entirely through your ABSS Connect portal.
Step 1: Access the Integration Portal
Log in to your ABSS Connect portal.
On your dashboard, navigate to the Integrated Application section.
Look for the InvoiceNow service module and click the Connect button.
Step 2: Start the Registration
Once you click Connect, the system will redirect you to the official InvoiceNow registration page.
Fill in your company's required registration details accurately (ensure your UEN and company name match your official ACRA records).
Tick the checkbox to accept the Terms and Conditions, then click Next. (Note: If you click 'Close' here, it cancels the process and returns you to the main dashboard).
Step 3: Finalize Your Setup
You will land on the final Registration page.
Simply follow the remaining on-screen prompts to authenticate and finalize the setup.
Once completed, your ABSS software is officially hooked up to the Peppol network and ready to send structured e-invoices!
Phase 2: Deactivating or Terminating InvoiceNow
Why would you need to deactivate? Usually, this happens if a company is restructuring, changing UENs.
Step 1: Initiate Termination
Go back to the Integrated Application section in your ABSS Connect portal.
Click the Terminate dropdown button and specifically select InvoiceNow.
Step 2: Confirm the Disconnection
A warning pop-up will appear. Read this carefully, as disconnecting means you will temporarily halt your ability to send compliant e-invoices directly through ABSS.
Click Proceed to confirm.
Step 3: IRAS Deactivation
ABSS will automatically redirect you to the IRAS Invoice Data Submission Deactivation page.
Follow the final on-screen instructions to formally remove your business from the active InvoiceNow linkage.
