A tool by {siteLink} — not a product of the Mustang project.
Drag in an e-invoice — ZUGFeRD, Factur-X or XRechnung, as XML or PDF. Your own Mustang checks it through the source entered in the settings of this app ( a Validator Bridge, a website with the validator plugin, or invoicePress.de ), and the report appears below with an explanation for every finding.
Check many invoices at once: a month folder, a ZIP or a selection of files. Each invoice goes to the validation service on its own, one after the other, and the overview lists the verdict of every file.
.xml or a ZUGFeRD / Factur-X .pdf
⚠️ The invoice goes to the source of the check and nowhere else. Its address is set under sources in config.js: a Validator Bridge, a website with the validator plugin or invoicePress.de. As delivered it is the Validator Bridge on this computer. The source runs Mustang and sends back its report, which this page reads and explains in the browser.
⚠️ What this page loads from outside is set in config.js. As delivered, the folder loads nothing from a website: the fonts and the rule catalogue lie inside it.
⚠️ This single file loads data from {site} but sends nothing from the invoice there. German and French with their rule catalogues, the code lists, Kits A and S, the fonts and the manual come from there; English and its rule catalogue are inside the file. Without a connection it shows English.
⚠️ Without the rule catalogue there are no plain-language explanations. If it cannot be loaded, the report shows the validator's own messages — complete, but in the validator's language.
