InvoiceNow consists of the transmitting and processing of automated invoices from one party to another.
There will be no need for the business to manually handle the invoice as the invoices are sent to the buyer’s Peppol-Ready accounting system through the secure network.
It is unlike sending a PDF file or a physical invoice. This reduces the cost and time spent on handling invoices manually.

On the Peppol network, an invoice document is firstly created by the supplier (known as Corner 1 or C1), and sent to their Access Point (known as Corner 2 or C2). C2 will send the invoice document to the buyer’s Access Point (known as Corner 3 or C3), who, will then forward the same to the buyer, (known as Corner 4 or C4). Working in conjunction with the Peppol Network, invoice data will be channelled to IRAS system (C5) via C2 and C3. To provide better understanding of mechanism for invoice data submission, we have classified each transaction type based on the business’ point of view.

With the invoice data submitted to IRAS, does that mean that businesses no longer need to keep their records?
Businesses need to continue to adhere to the prevailing record keeping requirements, which remain unchanged. The adoption of the GST InvoiceNow Requirement does not preclude businesses from having to comply with the mandatory record keeping requirements for GST-registered businesses.
Will I be penalised for any errors made on invoices sent to IRAS?
As a GST-registered business, you continue to be responsible for your GST obligations. These include ensuring that you comply with invoicing requirements when issuing an invoice electronically and report accurate GST returns. If you have made any errors, you may voluntarily disclose your errors and make good any tax that had been overclaimed or under-accounted for. Errors voluntarily disclosed within a grace period may qualify for penalty waiver or reduced penalties, subject to conditions under the Voluntary Disclosure Programme.
How will the invoice data transmitted to IRAS be stored? Is my data secure?
The invoice data will be stored in IRAS’ system, which is governed by public sector security requirements. IRAS is committed to safeguarding the confidentiality and security of our taxpayers’ data and upholding high standards of accountability. Refer to our Data Protection Statement and Privacy Statement for more information on how we handle the data that you have entrusted to us securely.
What is InvoiceNow?
InvoiceNow allows direct transmission of invoices in a structured digital format from one finance system to another using the Nationwide E-delivery network, which is based on Peppol , creating opportunities for automation. As such, both SMEs and large enterprises can enjoy smoother invoicing and faster payments, with shorter invoicing processing time without any manual paperwork.
I am already using PDF E-Invoice, why is InvoiceNow different?
In a common business scenario today, an PDF e-invoice is sent to the recipient organisation by email. This is a single-sided operation requiring your recipient to re-enter the details of the invoice into their own accounting system (e.g. accounts payable). A more complete solution should include the transmission of data from supplier system to buyer system without human intervention and potentially allow for the InvoiceNow invoice to be paid seamlessly.
What is Peppol?
Peppol is an international E-Document delivery network and business document standard form of Electronic Data Interchange (EDI) allowing enterprises to digitally transact with other linked companies on the Network.
Is InvoiceNow e-invoicing different from Peppol e-invoicing?
No, InvoiceNow e-invoicing is based on the Peppol business document standard and operates over the Peppol network and allowing enterprises to digitally transact with other linked companies on the Network.
