E-Invoicing
The Inland Revenue Authority of Singapore (IRAS) has introduced electronic invoicing, known as InvoiceNow, to standardise how businesses send B2B invoices. InvoiceNow runs on the PEPPOL network, which ensures that all invoices are submitted in a common format across businesses.
How E-Invoicing Works
E-Invoicing in Zoho Books is a simple and straightforward process. Zoho Books has partnered with a PEPPOL-accredited access point provider to help you send and receive invoices directly through the PEPPOL network in a structured digital format.
Zoho Books helps you create invoices in the PEPPOL BIS format, including all the required fields specified by IRAS. You can submit these invoices directly to your customers through the PEPPOL network from your Zoho Books organisation.
Note:For E-Invoicing to work, both you and your customers must be registered on the PEPPOL network.
