The invoicing system submits automatically
Invoice data is transmitted when the invoice is issued, rather than through a separate user operation.
SimplyX RTIR · M2M platform
A reliable connection
between your system and NAV.
SimplyX RTIR is the enterprise-side integration and monitoring platform. It validates data received from invoicing or ERP systems, submits it to the Hungarian NAV Online Invoice reporting M2M interface, then retrieves and retains the processing result.

NAV interface requirements in brief
Reporting is complete when NAV has processed the data successfully
Transmission alone is not sufficient. NAV must receive and process the data successfully; a failed submission must be repeated.
Official NAV Online Invoice interface documentationNAV expects a defined XML format
Data must be sent electronically to the Online Invoice system in the format and structure published by NAV.
NAV confirmation is decisive
The reporting obligation is fulfilled once NAV confirms successful processing. A rejected report requires a new submission.
The role of SimplyX RTIR
One platform for the complete machine-to-machine reporting flow
RTIR is designed to manage invoice data received from an enterprise system as a validated, traceable transaction through to the NAV response.
Two distinct roles: RTIR M2M is the SimplyX platform; NAV Online Invoice M2M is the government reporting interface it connects to.
- REST API intake with a unique idempotency key
- NAV Online Invoice 3.0 schema and blocking-rule validation
- NAV submission through RTIR and transaction-processing status retrieval
- Retries after temporary technical failures, with complete event history

Beyond the core reporting flow
Additional controls for the day-to-day use of Online Invoice data
Alongside submission through RTIR, the platform supports NAV data retrieval, verification and organisational access. These are complementary capabilities; its central role remains the reliable data connection between your enterprise system and NAV.
Inbound and outbound invoice data
Invoice data available in NAV Online Invoice can be retrieved, while query results and history remain searchable and exportable.
Compare RTIR data with VAT analytics
Inbound and outbound NAV data can be compared with VAT analytics, surfacing amount, date, missing-record and potential duplicate differences for review.
Hungarian and EU VAT numbers
Hungarian tax numbers can be checked against NAV data, while EU VAT numbers can be validated through VIES, individually or in batches.
Multiple companies and roles
Companies, users, API keys and access levels can be separated, supporting corporate-group and accounting-firm operating models.
Security and operational control
Reporting also needs to be demonstrable
Technical-user credentials, company separation, duplicate protection and a complete event history together make the process verifiable.
Technical-user protection
The password and keys required for the NAV Online Invoice interface connection can be managed as secrets, separately from application data.
Company-level access separation
Users can access only the reporting data and settings of the businesses assigned to them.
Duplicate protection
A unique idempotency key ensures that repeating the same request does not create another submission.
Logged lifecycle
Every relevant status and event remains traceable from data intake through the NAV processing result.
