AboutFatturaPA Validator
Validate a FatturaPA XML e-invoice before sending it to SDI: mandatory fields, Partita IVA and Codice Fiscale checksums, and IVA (VAT) math consistency across every line.Category: Fiscal ComplianceCatching SDI rejections before submissionAuditing IVA math on a batch of invoicesVerifying Partita IVA / Codice Fiscale checksums
The FatturaPA Validator tool is compatible with:Sistema di Interscambio (SDI)Italian Accounting Software.Run this before submitting to SDI, then use Invoice Sequence Auditor on the same invoice batch to confirm the numbering is gap-free before the fiscal year closes.SDI rejects malformed e-invoices after the fact, wasting a submission cycle. This tool runs the same structural checks locally: checksum validation on the issuer's Partita IVA and the buyer's Codice Fiscale using the official Agenzia delle Entrate algorithms, and a line-by-line audit that Imponibile × Aliquota IVA actually equals the declared Imposta. It also flags invoices with a 0% IVA line missing the required Natura code, one of the most common SDI rejection reasons.
Frequently Asked Questions:
Does passing this tool's checks guarantee SDI will accept my invoice?
No, it's a structural pre-check confirming the file is internally consistent, not a guarantee of SDI acceptance.
What's the most common issue it catches?
A 0% IVA line missing the required Natura code, which is one of the most frequent real-world SDI rejection reasons.
Built for Italian businesses and accountants who want to catch SDI rejection reasons before, not after, submission.
