Validation · One-file apps
A validation against the official rules tells you whether an e-invoice will be accepted. Here you validate with the official KoSIT validator, with Mustang, or with VAMPIRE JS entirely in the browser.
The Validation Explorers explain every finding in plain language, with field, value and spot in the invoice.
