From 2027, German companies may no longer send paper or PDF invoices to business customers – only structured e-invoices compliant with EN 16931. We bring XRechnung and ZUGFeRD into your existing ERP or custom software. No system replacement, at a fixed price.
Germany's e-invoicing mandate is law (section 14 VAT Act, as amended by the Growth Opportunities Act) and will not be postponed. It arrives in three stages.
Every domestic company must be able to receive, process and archive e-invoices – regardless of size.
Companies with more than EUR 800,000 prior-year turnover must issue e-invoices in B2B. Paper and PDF are no longer permitted.
The obligation applies to all remaining companies. Exceptions remain only for amounts under EUR 250, B2C and certain tax-exempt supplies.
A clear path from assessment to live operation – with fixed prices and no consultant-speak.
A paid initial assessment: we review your systems and invoicing processes and deliver a documented evaluation with concrete steps and a binding fixed-price quote.
We build the module that turns data from your ERP, database or a CSV export into valid XRechnung and ZUGFeRD files, validates and hands them over. Your system stays.
Selling industry software with an invoicing feature? We embed the EN 16931 module into your product – white-label – and maintain it as formats change.
XRechnung and ZUGFeRD change several times a year. A maintenance contract keeps your solution compliant – without you having to watch the calendar.
Clean handover to your tax advisor: a structured DATEV-format export instead of PDF chaos. On request we work directly with your firm.
Every generated invoice is checked against the official KoSIT validator. You receive validation reports as proof of due diligence – exactly as the Ministry of Finance recommends.
We analyse your systems, invoice types and edge cases. Result: a report telling you what needs doing – and a fixed price for the work. Paid, open-ended, no sales meeting.
We build the module, test it with your real invoices against the KoSIT validator and go live in a controlled way. Typical duration: weeks, not months.
Optional maintenance contract: we keep formats current and stay reachable when a customer needs a special invoice. You focus on your business.
Standards-compliant and built on a proven open-source core – no proprietary black box to lock you in.
Exactly where the vendor no longer delivers an update – or no longer exists at all.
Merchandise management from a software house that no longer exists, or a discontinued ERP version. No update is coming – we retrofit e-invoicing.
In-house and niche solutions that fit perfectly but don't know the standard. We add exactly the missing piece.
Small software houses whose customers need e-invoicing from 2027. We deliver the module to embed instead of learning it yourself.
High invoice volumes and many special cases (partial deliveries, credit notes, cash discount) – exactly the cases standard tools leave behind.
Clients with custom software or a dead ERP that standard DATEV material doesn't help. We are your technical partner for the hard cases.
Businesses effectively invoicing with Word and Excel that need a simple, validated route to a compliant e-invoice.
Receiving: since 1 January 2025 for all domestic companies. Issuing: from 1 January 2027 above EUR 800,000 prior-year turnover, from 1 January 2028 for everyone else. Legal basis: section 14 VAT Act as amended by the Growth Opportunities Act.
No. A structured record compliant with EN 16931 is required – XRechnung (pure XML) or ZUGFeRD 2.0.1+ (PDF with embedded XML). A plain view-PDF does not suffice.
Usually no. We add a module to your existing system that reads, converts, validates and exports the data. A new ERP is a six-figure, multi-month project – the retrofit takes weeks.
The readiness check starts at a fixed €1,900. An integration typically ranges from €12,000–30,000 depending on the system, with optional maintenance at €300–800 per month. The readiness check gives you the binding price.
That's our focus. Mapping these special cases correctly to the standard is the difference between "it works" and "rejected by the recipient". We test them with real documents against the KoSIT validator.
Yes. We deliver the export in DATEV format and, on request, coordinate directly with your firm so accounting gets clean data instead of PDF piles.
No. We provide technical implementation services – generating and validating standards-compliant e-invoices per EN 16931. Specific VAT questions stay with your tax advisor (section 5 of the German Tax Advisory Act). We don't say "your invoice is VAT-correct", we say "technically compliant with the XRechnung validation rules".
