The rule
A business that supplies Dutch central government must send it an e-invoice. The government prefers to receive it through Peppol; Digipoort and, since 29 August 2022, the government's supplier portal are the other routes. The Dutch government also lists a planned change: e-invoicing between businesses from 1 July 2030.
The Dutch Peppol IDs
A Dutch business is found by its Chamber of Commerce number (KvK, scheme 0106) or its VAT number (scheme 9944), and a government body by its OIN (scheme 0190). Zyntra OS checks the shape of each before saving.
