E-invoices in the trades

Receiving structured invoices already applies to B2B. The duty to send them comes in stages in 2027 and 2028. Sollmaß creates ZUGFeRD and XRechnung from the same source as the document – in the core of the software, not as a plugin, in the Office licence (€59, introductory price until 31 December 2026).

What counts by law

For B2B in Germany: the structured XML is the original. A PDF alone is not enough once the duty applies. The formats are XRechnung and ZUGFeRD from Comfort upwards under EN 16931. Public clients need the Leitweg-ID. Peppol is optional, and the way should stay open.

This is the legal framework, not tax advice. Your tax advisor checks turnover limits and deadlines.

What Sollmaß does with it

Quote, progress invoice, final invoice, credit note: the same document engine. XML and PDF come from one data record. The number runs on. A cancellation is a separate document, not a silent overwrite. The GoBD archive does not change silently.

The ZUGFeRD PDF is PDF/A-3b with an embedded factur-x.xml. We check both automatically with every change: the XML against the KoSIT validator, the PDF against veraPDF. Anything that fails there does not go out.

Customer, site, line items and tax are the same fields as on paper. If you write the document in Sollmaß, you should not have to pour it into a second e-invoice tool.

Tax advisor and DATEV

The document must stay machine-readable. For your tax advisor there are DATEV posting batches and a document package with XRechnung and PDF; direct transfer is the goal. We do not claim an RDS certification that we do not have.

Questions about e-invoices

Is a PDF enough as an e-invoice?

No, not once the duty applies: the structured XML is the original. Sollmaß creates ZUGFeRD and XRechnung from the same document as the PDF.

Is the e-invoice a plugin?

No. It sits in the core of the software for the trades, in the €59, with no extra module.

Is Peppol required?

No. Peppol is optional. XRechnung and ZUGFeRD are the core. In Sollmaß, sending via Peppol is prepared, not active yet.

Is Sollmaß DATEV-certified?

No. We do not claim a seal that we do not have. The document stays machine-readable, and CSV is not the end goal. Comparison
