Editorial and Trust Policy

Editorial policy

e-Invoice.app publishes compliance information on global e-invoicing mandates. Every country record is compiled from official tax authority publications, gazetted legislation, and accredited standards bodies. Where a mandate is contested or ambiguous, we record the ambiguity rather than present a single interpretation. Every country page shows the date it was last updated.

We write in UK English. We separate editorial content from sponsor placements. Sponsor units appear in clearly labelled sections and never inside FAQ answers, country data, compliance model descriptions, or glossary entries.

Primary sources

We draw country data from primary regulatory sources. Representative examples include EUR-Lex, Saudi Arabia ZATCA, UAE Ministry of Finance, GSTN India, OpenPeppol, Germany Federal Ministry of Finance, Direction Générale des Finances Publiques, Polish Ministry of Finance, and LHDN Malaysia. Each country page lists the specific sources we used for that country.

Update cadence

Country records are reviewed on an ongoing basis and republished whenever a source changes. Review is prioritised by mandate activity, so jurisdictions with live or imminent obligations are revisited more often than those with no announced programme. That means review dates vary widely across the register, and we do not claim every record is current to the same date.

Every country page shows the date its record was last verified, and every entry in our machine-readable files carries the same date, so you can always see how fresh a specific record is rather than relying on a site-wide claim. Where we have logged a dated change for a country, it appears on the news page, which is a running feed of tracked mandate changes rather than a complete history for every country.

Correction policy

If you spot an error on a country page, use the country discussion thread or email corrections to [email protected]. We respond to substantive corrections within two working days and publish the change date on the affected country page.

Sponsorship disclosure

e-Invoice.app carries sponsor placements from vendors that serve the e-invoicing market. Sponsor content is labelled in the user interface and separated from editorial content. Outbound sponsor links use the rel="sponsored" attribute where applicable. Sponsor relationships do not influence mandate status, country ratings, or editorial content.

Data licence

Editorial and compiled country data on e-Invoice.app is made available for individual reference use. Automated scraping and bulk republication are not permitted. For reuse enquiries, contact [email protected].

We publish a condensed, machine-readable summary of the register for AI systems and other automated readers at llms.txt, with a longer reference at llms-full.txt. Both carry each country's mandate status, key dates and verification date. Use of either file is subject to attribution: cite "Source: e-Invoice.app" together with the canonical URL of the country page the data came from. Those files are a summary for citation, not a licence to republish the register in bulk.
