NAV Online Számla 3.0 real-time invoice data reporting for Odoo — InvoiceData XML reported on every customer invoice
Connect Odoo to the Hungarian NAV Online Számla system. Customer invoices and credit notes are turned into the NAV InvoiceData XML, base64-wrapped in a manageInvoice request and submitted to NAV with your own technical-user credentials. The returned transaction id and processing status are stored on the move.
manageInvoice + status query
Token exchange, single-index invoice submission and transaction-status polling over the documented NAV REST API. Test and production endpoints are editable; requests retry with exponential backoff and every call is logged.
NAV 3.0 InvoiceData XML
A complete InvoiceData document: split supplier and customer tax numbers, per-line net / VAT / gross amounts in HUF, a per-rate VAT summary, exemption and out-of-scope cases, and storno / modification referencing for credit notes.
Technical-user authentication
The passwordHash (SHA-512) and requestSignature (SHA3-512 over the requestId, UTC timestamp and your signing key, folding in each invoice index hash) are computed exactly per the NAV interface specification, with AES-128 exchange-token decoding.
Real tax-number validation
The published NAV adószám check-digit algorithm runs on the
company and partners, with canonical
########-V-CC formatting and county / VAT-code range checks,
so typo'd tax numbers are caught before they reach the authority.
Business-rule validation
A Hungary rule set layered on the engine's EN 16931-style core checks the supplier and domestic-buyer tax numbers, the HUF expectation, the issue date, line descriptions and the storno reference before anything is submitted.
Bring-your-own-key
Your technical-user login, password, signing key and exchange key live on the connection record, never in the module. The signing key never leaves your server; everything else is transmitted only to the NAV endpoint you configure — nowhere else.
Guided onboarding
A wizard captures your Hungarian tax number and technical-user secrets, validates the tax number, optionally runs a token exchange to verify the connection and leaves the company ready to report invoice data to NAV. An optional cron drains posted documents to NAV in batches.
Compatible with Odoo 18 and Odoo 19.
Disclosure
This module transmits invoice data only to the NAV Online Számla endpoint you configure. Your technical-user secrets are stored solely on your own database and are never sent anywhere else.
