E-invoicing.
From obligation to a working process.

2028End of the transition period

Generally mandatory from 2028.

The transition period ends for domestic business-to-business transactions. E-invoicing then generally becomes mandatory.

For many, from 2027.

Businesses with prior-year revenue exceeding €800,000 must issue e-invoices one year earlier.

We support your transition, from the right invoice format and digital document exchange to accounting.

Statutory exceptions remain, including for small businesses under the German small-business VAT scheme and low-value invoices up to €250.
