## Invopop coverage

Formats, networks and systems Invopop supports in this country.

### Online Számla

Hungary's real-time invoice reporting system operated by the tax authority NAV. Invopop maps each invoice to the NAV OSA XML schema and transmits it over the secure web service the moment it is issued, covering B2B, B2G, and B2C.

- **NAV real-time reporting** — Invoice data is submitted to NAV through the Online Számla platform immediately upon issuance, as the RTIR model requires.
- **OSA XML generation** — Each GOBL invoice is converted into the NAV OSA XML format using the current schema version expected by the authority.
- **Per-invoice reporting** — Every standard invoice and correction is reported individually as it is issued.
- **B2B, B2G and B2C coverage** — The same reporting path applies across business, government, and consumer transactions.
- **Hungarian VAT compliance** — Hungarian VAT rules and reporting fields are applied so submissions meet NAV requirements without manual preparation.

### Peppol

OpenPeppol is the international four-corner network for cross-border B2B and B2G invoicing. Invopop connects you through a single integration as your Access Point, generating Peppol BIS 3.0 in UBL or CII, validating against EN 16931, and routing documents in both directions.

- **Bidirectional exchange** — Send invoices to any Peppol participant and automatically receive inbound documents through one integration.
- **UBL and CII** — Generate both Peppol BIS Billing UBL 3.0 and UN/CEFACT CII from a single GOBL source, with Invopop handling the conversion.
- **Participant registration** — Register companies as Peppol participants via API, including proof-of-ownership validation for platforms onboarding many merchants.
- **Participant ID lookup** — Validate recipient IDs before sending, derived automatically from VAT numbers or local business identifiers.
- **Visibility control** — Configure each party's presence across the SMP, SML, and Peppol Directory.

### PDF

The universal visual invoice that works for any recipient. Invopop renders a branded, multilingual PDF from the same GOBL source, with every field the destination country requires, locale-correct formatting, and built-in email or webhook delivery.

- **Every field, every format** — PDFs include every field the destination country requires, automatically.
- **Localized in 10+ languages** — Issue invoices in English, Spanish, German, Italian, Portuguese, Arabic, Greek, Polish, and more, with locale-correct date and number formatting.
- **Built-in email delivery** — Invoices are emailed directly to clients from Invopop's domain or your own.
- **Invoices, credit notes and more** — Produce standard invoices, proforma invoices, credit notes, corrective documents, and receipts.
- **Customisable templates** — Templates support logo configuration, standard page layouts, and per-locale formatting.
- **Built on GOBL** — Rendered from GOBL, the open-source invoicing standard, for full transparency and no vendor lock-in.
