Question 1

Is Invoice Navigator's e-invoice validator free?

Accepted Answer

Invoice Navigator offers a free online validator at invoicenavigator.eu/validator. Upload any e-invoice (UBL, CII, XRechnung, ZUGFeRD/Factur-X, Peppol BIS) and get instant validation against EN 16931 and country-specific rules — free, unlimited, no account required. Downloading the corrected invoice is also free for up to 3 different invoices per rolling 30-day window. For production volumes, the API plan 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 — and downloading the corrected invoice is free too, for up to 3 different invoices per rolling 30-day window. You pay for proof and volume: an Evidence Pack (signed certificate, validation report, and change log) is €7.90 per invoice, €29 for a 5-pack (€5.80 each) or €79 for a 20-pack (€3.95 each). The Practice plan (€29/month) gives accountants unlimited fixes; the API plan (€99/month) is for software. 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, and download the corrected XML at no charge for up to 3 different invoices per rolling 30-day window. The paid step is the audit Evidence Pack (€7.90 per invoice) — a signed certificate, the official validation report, and a change log for your records.

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, and Invoice Generator are all available at no cost, and corrected-invoice downloads are free within fair use (3 different invoices per rolling 30-day window). Paid plans start at EUR 29/month (Practice, unlimited fixes for accountants); API access starts at EUR 99/month.

Question 5

How do Invoice Navigator credits work?

Accepted Answer

Each credit covers one Evidence Pack — the validation report, change log of every auto-fix applied, SHA-256 integrity hash, and tamper-evident compliance certificate with QR verification code for one invoice. The corrected invoice XML itself is a free download within fair use. 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.
