Example session with this skill installed
Our German company had 1.2M EUR turnover last year. What are our E-Rechnung deadlines and which format should we use for B2B?
- Read your context and instructions
- Compiled the nex-einvoice-de
Based on your >800k EUR turnover:
- Since Jan 2025: You must be able to receive E-Rechnungen.
- From Jan 2027: Mandatory issuance of E-Rechnungen for domestic B2B.
Format Recommendation: Use ZUGFeRD EN 16931 (Comfort) for B2B to provide both XML for ERPs and a PDF for humans.

About this skill
The problem
German businesses face a staged e-invoicing mandate starting in 2025, but many SMEs are unprepared for the complex shift from PDFs to structured XML. Failing to comply with the Wachstumschancengesetz or GoBD archiving standards puts input-tax deductions and audit readiness at risk.
What it does
- Generates dated readiness checklists based on company turnover and customer mix.
- Provides format decision logic to choose between XRechnung and ZUGFeRD profiles.
- Maps paragraph 14 UStG mandatory invoice fields to EN 16931 business terms.
- Produces templates for GoBD-compliant Verfahrensdokumentation (procedure documentation).
- Calculates specific 8-year retention periods and archiving requirements under BEG IV.
Frameworks & tools
EN 16931, XRechnung 3.0.2, ZUGFeRD 2.4, UBL, UN/CEFACT CII, Peppol, and DATEV-compatible workflows.
Why this beats prompting it yourself
Generic LLMs often confuse EU-wide standards with specific German tax law (UStG) and administrative letters (BMF). This skill encodes the verified June 2026 legal status, including the transition waves for 2027 and 2028, ensuring you don't miss the nuances of Leitweg-ID routing or the difference between a "sonstige Rechnung" and a compliant E-Rechnung.
Use cases
- Assess a German SME's readiness for the 2027 versus 2028 issuance waves.
- Determine the correct ZUGFeRD profile for B2B versus B2G transactions.
- Draft a procedure documentation skeleton for a new digital invoice workflow.
- Verify if an incoming XML invoice meets the paragraph 14 UStG mandatory field requirements.
Known limitations
Does not provide legal or tax advice. Does not cover the core Peppol network mechanics or non-German country mandates (e.g., France) without companion skills.
