How does InvoiceNow work?

InvoiceNow adopts the Peppol framework which utilises the 4-corner model to direct transmit documents from Sage E-Invoicing solution to the same or another accounting/finance solution without human intervention. In the InvoiceNow network, documents are exchanged using a common XML format through Access Points, which serve as gateways into the InvoiceNow network. Access Points take up the responsibility of mapping documents into the standard format and sending them to the receiving Access Points through the InvoiceNow network.

GST InvoiceNow adopts InvoiceNow for invoice data submission to IRAS and extends the traditional 4-corner e-delivery model to a 5th corner.

1. Seller Creates and Sends Invoice

The seller issues a sales invoice using their Sage application and sends it digitally through the InvoiceNow network.

2. Sending Access Point (Sage)

The invoice first goes to Sage’s Access Point (AP) provider. Here, it’s checked against Peppol standards for accuracy. Once validated, the invoice is sent to the buyer’s AP provider. After the buyer’s AP confirms receipt, Sage’s AP also forwards the invoice details to IRAS.

3. Receiving Access Point (Buyer’s Side)

The buyer’s AP provider receives the invoice and delivers it straight to the buyer’s system.

4. Buyer Processes Invoice

The buyer imports the invoice into their ERP system to record the purchase—no manual data entry needed.

5. IRAS Gets the Data

Finally, the buyer’s ERP sends the purchase invoice to IRAS through their AP provider, ensuring compliance and faster GST reporting.
