Zirko Redaktion

This name sits under every post. Here is who is behind it, where the figures come from, and what to do when something is wrong.

Who writes

Zirko is built and run by a single person. Zirko Redaktion is the name that person writes under — no editorial team, no advisory board, no guest authors.

Where the figures come from

From the source itself: the text of the law, the regulation, the page of the authority in charge. Not from another vendor's summary, and not from a post about the text of the law. The references sit at the foot of every post, with their address and with the day we last opened them.

Today that is 223 posts across 23 markets. Every single one carries its sources — 1097 references in total.

In this market: 14 posts with 87 references.

What you will not find here

The posts describe the legal position; they are not legal or tax advice. Where a question is decided case by case, the post says so instead of giving an answer that is none. And what we do not know, we do not claim.

Where we have a stake of our own

We sell software for exactly the tasks we write about — quotes, invoices, hours, documents. Where a post touches them, its closing paragraph says what Zirko does. And what it does not: sentences such as “no software decides this” stand where they apply.

When something is wrong

Then it gets corrected, and the post carries the date of the change visibly above the text. If you find a mistake or miss a reference, write to us.

What we write about

  • Running the business — record-keeping and retention duties, deadlines, evidence for clients and authorities.
  • E-invoicing — formats, start dates, and what a business has to be able to issue and receive from when.
  • Costing — tax rates, progress payments, variations, and what an invoice has to state.
