WHAT IS INVOICENOW?
InvoiceNow is a nationwide E-Invoicing network that enables companies of all sizes to process invoices in a more efficient manner, reducing business costs and shortening payment cycles. InvoiceNow operates on the open standard Peppol (Pan-European Public Procurement On-line) framework, directly transmiting e-invoices in a standard digital format across different finance systems.
How it Works

InvoiceNow utilises the 4-corner model to transmit invoice data seamlessly from Suppliers to Buyers. This also allows for the secure exchange of electronic documents by eliminating manual work and errors.
The 5-corner model shown on the left includes the Tax Authority, to which GST-Registered Businesses in Singapore are required to send a copy of their invoice data.
As an IMDA-accredited Access Point Provider, SESAMi validates and transmits invoice data at C2 and C3.
