Context of the electronic invoice in Singapore

In Singapore, most companies (seller) issue invoices by extracting the data from their accounting/ERP systems and formatting it in human-readable form and sending it to the buyers via paper or email.

At the receiving end (buyer), manual effort is required to enter or scan the information into their systems which is a time-consuming and error-prone process.

In May, 2018 – Singapore announced the adoption of its own national e-invoice system to help businesses improve efficiency, reduce cost, enjoy faster payment and stay green at the same time. This network is an extension of the International Peppol (Pan European Public Procurement On-Line system) E-Delivery Network allowing businesses to transact internationally with other linked companies. Info-Communications Media Development Authority (IMDA) is the Peppol Authority in Singapore.
