Hungary NAV eNyugta
NAV receipt-data reporting (KOBAK) for the Odoo Point of Sale — a ReceiptData report on every POS order
From 1 September 2026 every Hungarian business must report the data content of the receipts it issues to the National Tax and Customs Administration (NAV) through the eNyugta / KOBAK receipt service. This module turns each Odoo Point of Sale order into a NAV ReceiptData XML document, base64-wraps it in a manageReceipt request and submits it with your own technical-user credentials. The returned transaction id and processing status are stored back on the order.
manageReceipt + status query
Token exchange, single-receipt submission and receipt-status polling over the documented NAV receipt REST API. Test and production endpoints are editable; requests retry with exponential backoff and every call is logged.
NAV ReceiptData XML
A complete ReceiptData document: the split supplier tax number, the cash-register / shop / cashier block, per-line net / VAT / gross in HUF, a per-rate VAT summary, the 5-HUF cash-rounding amount, the payment breakdown (cash / card / voucher / other) and STORNO referencing for refunds.
Built on the NAV RTIR connector
Reuses the proven Hungary NAV RTIR technical-user authentication: the passwordHash (SHA-512) and requestSignature (SHA3-512 over the requestId, UTC timestamp and your signing key, folding in each receipt index hash) plus AES-128 exchange-token decoding. No crypto or tax-number logic is duplicated.
Daily aggregate fallback
For manual or non-connected paper receipts, an AggregateReceiptData document sums a session's or a day's receipts per VAT rate for submission inside the legal three-day window. A wizard and an optional cron build and submit it for you.
Real tax-number validation
The published NAV adószám check-digit algorithm runs on
the company taxpayer, with canonical ########-V-CC
formatting and county / VAT-code range checks, so a typo'd tax number is
caught before it reaches the authority.
Business-rule validation
A receipt rule set layered on the engine core checks the supplier tax number, the HUF expectation, the receipt number and date, line descriptions, the payment / gross reconciliation (allowing the 5-HUF cash rounding) 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 receipt data to NAV. Optional crons drain orders one by one or as a daily aggregate.
Compatibility
Compatible with Odoo 18 and Odoo 19.
Disclosure
This module transmits receipt data only to the NAV eNyugta endpoint you configure. Your technical-user secrets are stored solely on your own database and are never sent anywhere else.
