How to research an e-invoicing mandate safely

Use primary sources, distinguish enacted law from proposals, track rollout waves and record a review date.

What it means

Mandate research should begin with the authority and primary legislation, then technical specifications, release notes and accredited network material.

Search-result snippets and vendor summaries are discovery aids, not final authority.

Implementation method

  1. 1
    Record the legal scope, transaction type, entity criteria and effective dates.
  2. 2
    Separate issuance, receipt, reporting, transport and archiving obligations.
  3. 3
    Capture schema/API versions and official publication dates.
  4. 4
    Set a review date and monitor official change channels.

Questions and answers

How often should country pages be reviewed?

Review frequency should reflect the rollout stage; active transitions may need monthly or event-driven checks.

How should uncertainty be shown?

State what is confirmed, the source date, what remains conditional and where the user must verify their facts.

Can EInvoiceLab officially certify mandate research?

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.
