EN 16931 business terms and the rules that check them

A validator reports rule codes. An invoice has fields. This is the index between the two: every business term the rule catalogue names, with every rule that constrains it, quoted as the standard states it.

Everything here is computed from the rule catalogue and nothing else. Two facts about that catalogue are worth stating up front, because they remove questions people arrive with: every rule in it is an error rather than a warning, and every rule applies to both invoice syntaxes. So there is no rule that can be safely ignored, and none that is specific to one of the two formats.

Nothing here states a tax obligation, a rate, or a national requirement. The catalogue holds structural validation rules, and those are a different thing. For the rules themselves, with the reason each one fires and how to fix it, see the rule reference. For the same catalogue cut by VAT treatment, see the VAT categories.

The invoice itself

Fields that identify the document rather than describing what is on it. Most are constrained by a single core rule, so few of them reach the page threshold.

Seller, buyer and representative

Identifiers for the parties. These are the fields whose presence depends on the VAT category of the lines, which is why the identifier terms here carry more rules than anything else in the parties block.

Why this is one page

The catalogue is a machine rule set, and its statements are written to a template. The rule for a document level allowance reason and the rule for a document level charge reason are the same sentence with one word changed. Six pairs of terms are constrained by exactly the same rules. Splitting this index into a page per field reproduces that repetition as a set of pages that differ by a word, and none of them would tell a reader anything the page beside it did not.

What is useful is the pattern itself: that the allowance block and the charge block are mirrored, that the totals each carry one calculation rule and one decimal rule, that the VAT breakdown terms carry more rules than anything else because each is checked separately for every category. Reading that off one page takes a minute. Reading it off eighty-four takes an afternoon.
