SG BIS 3.0 Specifications

Peppol Business Interoperability Specifications (BIS) is developed in Europe for the eProcurement processes to standardise electronic documents exchanged between sending and receiving Access Points (AP). For exchanges of electronic documents which are non-European, i.e. Singapore, then the country specific BIS Billing 3.0 specification is to be adopted instead of the Peppol BIS Billing 3.0.

In Singapore, SG Peppol Bis Billing 3.0 has been adopted in order to cater for country specific requirements such as:

  • Replacement of VAS (Europe) to Singapore’s GST (Goods and Services Tax) and to cater for non-GST registered businesses;
  • Specific GST calculation and rounding steps for presenting amount in invoices
  • Update of GST code list value to identify the specific GST categories available to use; and
  • Singapore specific payments such as Direct debit using GIRO and Credit Transfer using Unique Entity Number (UEN)-based PayNow Corporate

Transacting with Partners

Sending E-Invoices to Government

The Singapore Accountant-General’s Department (AGD) provides government vendors with the additional channel to send e-invoices to the Government over the nationwide e-invoicing network, now called InvoiceNow.

AGD considers InvoiceNow as the preferred channel for suppliers to submit e-invoices to the Government agencies via this network. By using InvoiceNow to send e-invoices, government vendors can use the same business process to directly transact with the Government from their own systems and with other business counterparties on the network. This will bring more benefits to the participating businesses in the long run.

Please refer to the guide developed by AGD here that explains how you may do so, and the requirements to comply with.
