What it means
Invoice validation is a stack: file integrity, syntax, semantics, code lists, country profile, identity, security, transport and official outcome.
Each layer answers a different question, so one green result cannot substitute for the rest.
Implementation method
- 1Hash and preserve the source.
- 2Detect the document profile and version.
- 3Run syntax, semantic and national validations.
- 4Confirm routing identities and recipient capabilities.
- 5Submit through the correct channel and retain the final outcome.

Questions and answers
What is the minimum useful local preflight?
Parseability, profile detection, required business terms, arithmetic, identifiers, dates and obvious code-list checks.
When is validation complete?
When the required technical layers pass and the authoritative network or authority reports the expected final status.
Can EInvoiceLab officially certify the invoice validation stack?
No. EInvoiceLab can inspect, prepare and explain technical data, but official conformance, delivery or acceptance depends on the active authority, network, accredited provider and validation artefacts.
Should I keep the original structured file?
Yes. Preserve the original XML or JSON, its hash, every validation report and the final authority or network response. A readable PDF should not replace the source document.
