Here you find the NSGB eReceipt specification used in the eReceipt pilot. NSGB eReceipt is based on Peppol BIS billing 3.0 with the use of additional item properties to include eReceipt-specific information. In the future, there will be a separate eReceipt specification that can be used in the Peppol Network or in other forms of transactions, such as wallet technology.
