Question 1

Is Invoice Navigator's e-invoice validator free?

Accepted Answer

Invoice Navigator offers a free online validator at invoicenavigator.eu/validator for one-off invoice checks. Upload any e-invoice (UBL, CII, XRechnung, ZUGFeRD/Factur-X, Peppol BIS) and get instant validation against EN 16931 and country-specific rules. The free tier includes 500 invoices per month with full engine access. For production volumes, Pro is EUR 99/month for 10,000 invoices.

Question 2

How much does Invoice Navigator cost?

Accepted Answer

Validation is free, unlimited, and requires no account — you can validate any EU e-invoice and see every error with plain-language explanations at no cost. You only pay when you need to download the corrected file: €7.90 for a single Evidence Pack, €29 for a 5-pack (€5.80 each, save 27%), or €79 for a 20-pack (€3.95 each, save 50%). No subscriptions, no monthly minimums, no credit-card-required for the free path.

Question 3

Does Invoice Navigator offer a free tier?

Accepted Answer

Yes — validation is fully free and unlimited, no account or credit card required. You can validate any EU e-invoice (UBL, CII, XRechnung, Peppol BIS, Factur-X, ZUGFeRD), see every error with plain-language explanations, preview the auto-fix to see exactly what would change, and walk through guided fixing for missing-data errors. The free path covers everything except downloading the corrected XML and the audit Evidence Pack — those are the pay-as-you-go steps at €7.90 per download.

Question 4

Are the e-invoicing tools free to use?

Accepted Answer

Yes, basic usage of the online tools is free with no account required. The Format Finder, Invoice Validator (single invoice checks), and Invoice Generator are all available at no cost. For production use with API access, batch processing, auto-remediation, and Evidence Packs, paid plans start from EUR 249/month.

Question 5

How do Invoice Navigator credits work?

Accepted Answer

Each credit covers one Evidence Pack download — the corrected invoice XML, validation report, change log of every auto-fix applied, SHA-256 integrity hash, and tamper-evident compliance certificate with QR verification code. Credits come in three sizes: single (€7.90), 5-pack (€29, €5.80 each, save 27%), or 20-pack (€79, €3.95 each, save 50%). They work across every supported format — XRechnung, ZUGFeRD, Peppol BIS, FatturaPA, Factur-X, and all 27 EU country-specific CIUS variants. Re-download access for each Evidence Pack is included for 90 days.
