Send and receive invoices directly between finance systems, and send the same data to IRAS.
InvoiceNow is Singapore’s national e-invoicing network. It was set up by IMDA and runs on Peppol, an international standard. It lets your finance system send an invoice straight into your customer’s finance system. No PDF. No email. Nobody types it in again.
GST-registered businesses must also send their invoice data to IRAS through the same network. This is being phased in by business size.
Highlight
Invoices go system to system, not by email
Nothing is re-typed at either end
Invoice data reaches IRAS at the same time
The same connection reaches overseas Peppol partners
