If your company needs to issue invoices to clients or public agencies in Singapore, it’s important to know that the country now requires e-invoicing for many transactions. This is done through a national system called InvoiceNow, which allows invoices to be sent digitally using international standards. The goal is to make invoicing faster, more secure, and directly connected to Singapore’s tax authority, the IRAS.
InvoiceNow is based on the Peppol network, a global framework used in many countries. In Singapore, businesses must use a certified Peppol Access Point provider—such as B2Brouter—to connect to this network. This provider helps your company send invoices in the correct format and ensures they reach both your customer and the government system for GST (Goods and Services Tax) reporting.
Over the next year, Singapore will make e-invoicing mandatory for more businesses, and the current format (SG Peppol BIS 3.0) will be replaced by a new version called Peppol PINT SG. If you are new to doing business in Singapore, this page will help you understand the key dates, formats, legal rules, and how to start using InvoiceNow correctly from the beginning.
