PDF in.
E-invoice out.
Your E-Invoice Plumber takes care of the pipes — powered by formatklar.
Since 2025 companies in Germany must be able to receive e-invoices, and from 2027 they must send them too. Sounds like a building site? It is — but not yours: upload your PDF invoice, briefly check what our AI read, and out comes a valid XRechnung. If you would rather send a readable PDF, you also get the invoice as a ZUGFeRD PDF.

The workbench — try it right here
This is how the real tool feels: drop it in, check it briefly, take it out. Click your way through.
The above is a preview with sample data. To the real workbench - there we unpack your ZUGFeRD PDF, free and without signing up.
The mandate is turned on step by step
Receiving is mandatory
Every company must be able to accept e-invoices — an email inbox is legally enough, but someone has to be able to read, check and archive the XML.
Sending becomes mandatory
For companies with more than €800,000 in prior-year revenue. Plain PDF invoices without a data set to domestic business customers will be history.
Then it applies to everyone
Including the smallest business. Anyone who has switched by then simply turns the tap further.
Where do you stand? The free check will tell you — in 15 minutes.
Blockage in the routing ID?
E-invoice rejected, error code cryptic, the authority waiting? Drop the file into the validator. We translate every error code into plain language — with a recommended action, not just a diagnosis.
formatklar explains: Sounds like a motorway junction, but only means the buyer reference is missing. Authorities reject invoices without it — enter your client’s routing ID (Leitweg-ID) in the “buyer reference” field. No stress: the converter asks for it before the file is created.

Four tools, one handle — all in the browser, all in plain language.

The price board
It hangs on our wall.
All prices exclude VAT, no surcharges. A fixed price replaces the hourly rate — you never pay both.
Nothing fits? Then we put your package together in the free intro call — calculated openly from €80/h.
Or you let us do it
Quick start
Two to three sessions by screen sharing: First we look at what your software can already do. Then we set up receiving and sending — in your software or pragmatically with what you have. Finally two test invoices and a short guide. Then 30 days of follow-up support by e-mail in case a question comes up after all.
€400 fixed price (5 h at €80)
Book a quick startIntegration
When your software cannot do e-invoicing itself: we connect it to your ERP or industry software — vendor-independent, with analysis, testing on real transactions and training.
from €1,590 fixed price (≈ 20 h at €80)
View integrationIndividual support
For everything a fixed price does not cover — and by no means only e-invoicing: the printer that will not print, the email account on the new phone, the link to your accounting interface, order in the flow of receipts to your tax adviser. Remotely by the hour with no minimum — or at your premises, together with your tax adviser if you wish.
€80/h remote, no minimum (on site: first hour €100 incl. travel, 50 km around Achern — then €80/h)
Check distance and priceAsked briefly, answered clearly
Do I really have to do this already?
Receiving: yes, since 2025 — every company. Sending: from 2027 above €800,000 in prior-year revenue, from 2028 for everyone. Small businesses must be able to receive, but need not issue e-invoices themselves. The free 15-minute check clarifies what that means for you specifically.
XRechnung or ZUGFeRD — which do I need?
XRechnung is pure XML — mandatory for authorities, equally valid to companies; ZUGFeRD is a PDF with embedded XML and popular in B2B because you can still read it. You need one of the two — depending on the recipient, never both to the same one. We deliver the XRechnung and, on request, the ZUGFeRD PDF; public-sector portals usually accept only the XRechnung as XML.
What happens to my files?
Checking, unpacking and creating run on our server in Germany, purely in memory — your file is never written anywhere, so there is no deletion period either. Only the AI reading passes the PDF to a reading service, currently outside the EU; we switch to EU processing before the public launch, and until then the interface says so before you upload. Nothing is used for AI training. Retaining your invoices for tax purposes remains your responsibility.
My software cannot do this. Do I have to switch?
Usually not: the quick start sets up receiving and sending in your existing software. If your software really cannot play along, there is integration or data migration at a fixed price — vendor-independent, we do not sell software.
And what does the consulting cost?
The first 15 minutes nothing, after that €80/h excluding VAT remotely, no surcharges. On site the first hour costs a flat €100 including travel (50 km around Achern), every further hour €80. As soon as a fixed price fits (quick start, integration), the fixed price replaces the clock.
