E-invoices for DATEV: check, archive and hand over documents
Receive e-invoices, check them against the official KoSIT validator and hand them over to your tax advisory firm with one click as a DATEV document transfer export: all document images plus a structured document data index, ready for DATEV Unternehmen online or Belege online. DATEV is the accounting software used by most German tax advisers.
From inbox to tax adviser
Every invoice validated
Incoming e-invoices are checked against the official KoSIT validator (EN 16931/XRechnung), including an IBAN fraud comparison against your supplier history, before anything is paid.
Original frozen
Every document is archived as the unaltered original (PDF and XML) with a SHA-256 checksum, and finalised invoices can no longer be changed. This supports storage in line with the GoBD (German rules for digital bookkeeping records).
DATEV export as ZIP
One click creates the document transfer export: document images plus a document data index (CSV with number, date, net/VAT/gross, issuer), for import into DATEV Unternehmen online or Belege online.
Why documents instead of booking entries?
In practice, automatically generated booking entries fail because of the chart of accounts: it belongs to the client or the tax advisory firm, not to the invoicing tool. That is why our export deliberately provides the checked original documents plus a structured index, and the firm books in its own system with its own account assignment logic. This is faster than correcting faulty automatic entries, and it keeps responsibility where it professionally belongs.
For tax advisory firms
Check, report and export bundled
For firms with many clients we bundle incoming invoice checks, check reports and the DATEV export on terms available on request, so client documents arrive checked and ready for handover instead of as a loose collection of PDFs.
Check report as per the BMF letter
For every checked incoming invoice there is a check report (PDF) with the KoSIT result and the IBAN check: the validation report within the meaning of the BMF letter of 15 October 2025 (German Federal Ministry of Finance, margin no. 35a). More in the guide.
FAQ: e-invoices & DATEV
How do I get e-invoices into DATEV?
Via the DATEV document transfer export (Belegtransfer): a ZIP with all archived documents (document images as PDF/XML) plus a structured document data index as CSV with number, date, amounts and issuer. You or your tax advisory firm import the ZIP into DATEV Unternehmen online or DATEV Belege online as document images.
Does the export create ready-made booking entries?
No, deliberately not. Booking entries need the client's chart of accounts and account assignment logic, and those sit with the tax advisory firm. The export delivers the documents plus a structured index so the firm can book quickly in its own system instead of correcting faulty automatic entries.
Which documents end up in the DATEV export?
All archived documents of the account: outgoing invoices you created as well as incoming invoices received and checked via the mailbox, each frozen as the unaltered original (PDF and/or XML) with a SHA-256 checksum.
Is the storage GoBD-compliant?
The platform supports storage in line with the GoBD (German rules for digital bookkeeping records): documents are frozen as unaltered originals with a checksum, finalised invoices can no longer be changed, and the full export includes an integrity manifest together with a process documentation template. For the statutory retention period we recommend also keeping the export in your own archive. This does not replace tax advice.
Is there an offer for tax advisory firms?
Yes. For firms with many clients we bundle incoming invoice checks, check reports and the DATEV export across multiple clients on individually agreed terms, so that every client invoice arrives checked and ready for handover. Get in touch.
How does the check report help with input VAT deduction?
According to the BMF letter of 15 October 2025 (a guidance letter from the German Federal Ministry of Finance, margin no. 35a), you may rely on the technical result of a validation provided you exercise due care; the retained validation report serves as evidence. That is exactly what our check report provides for every checked incoming invoice. Details in the guide to input VAT deduction and input VAT protection.
