See a dry run on a sample invoice.

  • In the sandbox

In plain words

Try it shows a dry run on a sample invoice without any setup: pick a sample and read the answer, which names the field and says who fixes it. All the invoices are invented.

A dry run shows what makes eurinvoice different: when an invoice is wrong, the answer names the field, gives a catalogue code and says who fixes it. Pick an invoice and read the answer.

Sample data only. Do not type a real invoice, a real company or a key for a live system. Nothing you type is stored on a server, and nothing leaves this page in sample mode.

Recorded answers, 7 Oct 2026. Each was recorded from the service and is replayed here. The XML was built by the service's own code. No server is called.

A German software firm bills a brewery. The KoSIT validator checks the file.

What you see

Each of the six invoices is an invented sample, run once through POST /validate, with its answer saved. The page replays that answer: it calls no server and stores nothing. The XML on a valid answer was built by the service's own code, and its hash equals the one the service reported.

What it does not do

  • It stores nothing, and it has no accounts. A dry run queues and sends nothing.
  • It works for business-to-business invoices only.
  • It supplies no legal wording. For reverse charge and exempt invoices, enter the basis yourself.
  • It does not run a dry run on an invoice you change. To do that, ask for a sandbox key and call POST /validate.
