InvoiceIn checks · validation rule

InvoiceIn checksError

The XML elements are in the wrong order. XML schemas for e-invoices (UBL, CII, FA(3), FatturaPA) define a strict sequence; the message names the element found and the one expected. Reorder the children to match the schema.

Field: (XML element named in the message)
Rule set: InvoiceIn checks
Who has to fix it: The sender

This is a property of the file you received, so it cannot be corrected on your side without changing the document — ask the supplier to reissue it.

Check your own invoice

Drop the file that failed. We parse it, run the official rule sets against it and list every finding with a fix — 20 invoices per day, no key, nothing stored.
