Who writes this
InvoiceSnap is published by FusionStudios, a web design studio based in the Netherlands. The content is researched and maintained by the invoicesnap editorial team.
We are not accountants or tax advisers, and we say so on every guide. That is precisely why the sourcing rule below is absolute. The authority on what a German invoice must contain is the German tax administration, not us. Our job is to find what they published, quote it accurately, say when we read it, and link you straight to it so you can check us.
Which sources count
In descending order, and we only ever use the first tier for a legal claim:
- Primary. The tax authority, revenue service or legislature that publishes the rule: the Belastingdienst, HMRC and GOV.UK, the IRS, the ATO, the CRA, EUR-Lex for EU directives. Statute text where the authority publishes it.
- Official secondary. Guidance from the European Commission or an equivalent body that restates a directive. Used for context, never as the sole support for a specific figure.
- Everything else. Not used for legal claims at all. Accountancy firm blogs, invoicing software guides, forum answers and news write-ups can be right, but they go stale silently and they restate the rule at one remove.
If a fact cannot be traced to a tier-one source, one of three things happens: it is softened to describe common practice rather than law, it is marked as unverified, or it is left out. It never gets published as a confident statement with nothing behind it.
How often we check
Every guide and every country page carries a last reviewed date, which is the day a person last read the page against its sources. It is not the date of the last deploy and a typo fix does not move it.
- Every page is reviewed at least once every twelve months. A build check fails if any page passes that limit, so the deadline is not a good intention.
- Pages are reviewed immediately, outside that cycle, when an authority publishes a change we become aware of. Rates, thresholds and e-invoicing dates move the most, so they are checked first.
- An out-of-date page about tax rules is worse than no page, because it looks current. If we cannot maintain a country page properly, we remove it rather than let it drift.
How we correct mistakes
If something here is wrong, tell us through the contact form and point at the source if you have one. Corrections to a factual claim are made as soon as we can verify them, the review date moves, and a substantive correction is noted on the page itself rather than quietly edited away. We would rather visibly change our mind than look like we were right all along.
Money, and where it is not allowed to reach
The tool is free, has no watermark, no limit and no account, and that does not change. The site may carry clearly labelled commercial links in future. Where it does, these rules bind:
- Position and verdict are never for sale. If this site ever compares products, no partner can pay to appear in that comparison, to rank higher within it or to soften what is said about a competitor. A partner can appear beside a comparison, labelled, never inside it.
- Commercial links are always labelledas such, in visible text next to the link and in the markup, and never placed inside a guide's factual answer.
- Nothing commercial goes near the tool. No advertising and no partner links on the invoice or quote generator, no third-party script that could see what you type, and nothing at all inside the embeddable widget.
- No paid links, in or out. We do not buy links, sell links, or accept paid guest posts.
What we will not write
- Advice about your own tax position. We describe published requirements. Whether a rule applies to you depends on facts we do not have.
- A rate, threshold or deadline without a source. Not one.
- A country page for a country whose primary source we have not actually opened.
- Bulk generated pages. Every page here is a deliberate decision, not the output of a loop over a list of keywords.
Reaching a person
The contact form is read by the people who build the site. A published contact address is still to be added; until it is, the form is the reliable route. See also our methodology, which lists the specific source behind each country.
