Beyond e-Invoicing, Singapore has required additional e-documents such as Order and Invoice Response as mandatory for AP’s and IRSP’s to be supported on the InvoiceNow network, delivering greater efficiency in procurement processes and assisting enterprises with greater digitisation of their business workflows.
The Invoice Response specification enables Invoice senders to be provided with a status update of their invoices sent via the InvoiceNow network instead of using manual email notification on the status of the invoices.
The Order Only BIS enables orders to be sent through the Peppol network. The Order only BIS is a simple process with only an order document being sent from a buyer to a seller. Any response from the seller would be through other (non-Peppol) communication channels.
The Ordering BIS enables orders to be sent through the Peppol network. The Ordering BIS uses the same order document to send an order from a buyer to a seller but with the addition that the seller shall send a response to the buyer to confirm, reject or modify the order.
The Advanced Ordering BIS enables orders to be sent through the Peppol network. The Advanced Ordering BIS makes it possible for the buyer to send order changes and cancellations to the seller.
The Order Agreement BIS allows a seller to send an order document to the buyer. In cases when the buyer has submitted an order through a web page, by email or by telephone, This BIS enables to seller to send the order, as received, to the buyer for confirmation and for the buyer’s reference.
Singapore has introduced SG Order Balance 1.0 as a new document on the InvoiceNow network to support local requirements, with this Order Balance document buyers are able to inform sellers of the remaining balance of an order.
