Singapore currently does not require mandatory e-invoicing for B2B or B2G transactions, but taxpayers can issue them voluntarily via the InvoiceNow platform. The InvoiceNow network is based upon the Peppol network (Peppol BIS billing 3.0 standards), though VAT-related rules have been replaced by GST rules. The IMDA strongly recommends e-voicing although it is not mandated. The IMDA (Infocomm Media Development Authority) of Singapore has updated the FAQ related to InvoiceNow, which provides information on what InvoiceNow is, how it differs from PDF e-invoicing, and many other useful details. It is expected that Singapore will mandate the use of the InvoiceNow platform for B2G transactions in the near future , However no specific timeline has been revealed yet.
