How do businesses comply with Singapore's InvoiceNow e-invoicing network?
Singapore's InvoiceNow network is a Peppol-based national e-invoicing network operating under IMDA oversight. Government procurement has mandated InvoiceNow for suppliers from 2022. For the private sector, adoption is encouraged with incentives. Businesses register a Peppol participant ID via an access point provider accredited by IMDA and use supported accounting software to send and receive invoices via InvoiceNow.
