The Accountant Tools tool is compatible with:Invoice ExportsClient RegistriesPayroll Data.Validate client identifiers with ACCOUNTANT first, then send flagged rows through COLUMN_VALIDATOR for custom business rules or DATA_HEALTH for a full quality report before filing with the Agenzia delle Entrate.
Runs the official Italian checksum algorithms for Codice Fiscale and Partita IVA against every row, flags malformed IBANs using the standard mod-97 check, and recalculates IVA at the 4%, 10%, and 22% brackets on invoice line items so discrepancies surface before a filing deadline. Because validation runs entirely client-side, client registries, payroll exports, and invoice data never touch a server.

Frequently Asked Questions:

What does it validate?

Codice Fiscale, Partita IVA, and IBAN numbers in bulk across a CSV or Excel export, plus computing IVA on invoices.

Does my client data leave the browser?

No, all validation runs locally, no account or client data is uploaded anywhere.

Built for commercialisti and bookkeepers who need to catch invalid fiscal codes and IBANs before a batch payment or filing, not after.
