Enterprises connected to the network can transact internationally with other connected enterprises, enabling business process interoperability where business documents can be exchanged automatically without manual intervention.  \n▪ To find out more about InvoiceNow or how to connect to the network, you may visit IMDA’s website [at ](at www.imda.gov.sg/invoicenow)[www.imda.gov.sg/invoicenow](at www.imda.gov.sg/invoicenow).  \no Note: This network is only applicable for enterprises registered with a Unique Entity Number (UEN) .  \n▪ This guide sets out the requirements for e-invoice submission to Singapore Government agencies via InvoiceNow, which is the Government’s preferred channel for receiving invoices.  \n2  \n\n|  | Requirements |\n| --- | --- |\n|  | To submit e-invoices to Singapore government agencies via InvoiceNow, vendors would have to comply with the following requirements:\u003Cbr>1) Have a CorpPass account at CorpPass portal ([Corppass.gov.sg](Corppass.gov.sg))\u003Cbr>• To find out how to register for a CorpPass account and set up the Vendors@Gov e-service at the CorpPass portal, please refer to this guide.\u003Cbr>2) Have an “Approved” vendor record at Vendors@Gov ([vendors.gov.sg](vendors.gov.sg))\u003Cbr>1.
