Readers
Every document goes through two, from different vendors. Two runs of one model make correlated mistakes — a second opinion is only worth having if it can be wrong differently.

Needs the Croatian language data installed, and reads text rather than understanding documents — it never produces named fields, so it cannot be one of the two readers.

Not a reader. The invoice arrives as structured XML, so there is nothing to read and nothing to settle — every field is exact and both readers are skipped. Every document that arrives this way is one that can never be misread.
Prices are indicative and move often; they exist so an estimate before a thousand-page month is the right order of magnitude, not so anyone bills against them. Keys are the workspace's own — nothing here is resold.
