The last transition step: from 1 January 2028 every German business, regardless of turnover, must issue structured e-invoices for domestic B2B supplies. EDI procedures must also be EN 16931-compatible by then.
Who is affected
Micro and small German businesses below €800,000 turnover that were still allowed to send PDF/paper invoices in 2027.
Sizes: micro, small · Sectors: All sectors · Applies if: We invoice other businesses (B2B)
What to do
Move to an invoicing tool that outputs XRechnung or ZUGFeRD, check that your EDI connections can extract EN 16931 data, and inform customers of your e-invoice delivery method.
