Frequently asked questions about e-invoicing
What is an e-invoice — isn’t a PDF enough?
An e-invoice is an invoice in a structured, machine-readable format (e.g. ZUGFeRD or XRechnung). A plain PDF or a scan no longer counts as an e-invoice since 2025, because the data cannot be read automatically. ZUGFeRD combines both: a visible PDF with embedded XML.
When is the e-invoice mandatory in Germany?
Since 1 January 2025, domestic B2B companies must be able to receive e-invoices. Mandatory sending of structured e-invoices is phased in from 2027 (larger companies) and from 2028 across the board. Switching early keeps you on the safe side.
What is the difference between ZUGFeRD and XRechnung?
XRechnung is a pure XML format, mainly used for invoices to public authorities. ZUGFeRD (Factur-X in France) is a hybrid: a PDF for humans with embedded XML for machines. For most B2B invoices in SMEs, ZUGFeRD is the most practical choice.
Which mandatory details must an invoice contain under §14 UStG?
Among others: full name and address of supplier and recipient, tax number or VAT ID, issue date, sequential invoice number, quantity and type of service, service date, net amount and the applicable VAT rate and amount. n3tz checks these fields automatically before sending.
Can I turn my existing quotes into invoices?
Yes. In the dashboard (Zentrale) an accepted quote becomes a §14-UStG-compliant e-invoice with one click — avoiding double data entry and transfer errors.

Quotes and e-invoices (ZUGFeRD) are included in the Premium plan — 299€/month including AI phone, AI chat, appointment booking and review management. Cancel monthly, 30-day money-back guarantee.
