# Regulatory definitions

> A glossary of the main terms used in e-invoicing and e-reporting regulations, standards and tax authority platforms.

This section clarifies terms as they are defined or used in relevant laws and official technical standards. It serves as a reference for understanding the legal and compliance context that governs invoicing, reporting, and certification requirements.

The [Global](#global) section covers the vocabulary shared across jurisdictions — models, standards, networks and record-keeping obligations. The country sections that follow cover the local systems, formats and identifiers, and link to the corresponding [compliance](/compliance/europe) page or [app](/apps) where one exists.

### Models and architecture

|                        |                                                                                                                                                                                                                                                                         |
| ---------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Centralized model**  | E-invoicing model where every invoice is routed through a single state-run hub that all taxpayers must use (Italy's SDI, Poland's KSeF)                                                                                                                                 |
| **Clearance model**    | Regulatory architecture where invoices must be validated and approved by the tax authority before becoming legally valid — the cleared document, not the original, is the legal invoice                                                                                 |
| **CTC**                | Continuous Transaction Control, umbrella term for regimes where transaction data reaches the tax authority at or near the moment of the transaction instead of in a periodic return                                                                                     |
| **DCTCE**              | Decentralized CTC and Exchange, model where accredited service providers exchange the invoice over a network and report the data to the tax authority in parallel — the basis of France's Plateforme Agréée model, Croatia's Fiscalization 2.0 and the EU's ViDA design |
| **Post-audit model**   | Traditional model where invoices are exchanged directly between the parties and the tax authority checks them after the fact, during an audit                                                                                                                           |
| **RTIR**               | Real-Time Invoice Reporting, where the supplier issues and delivers the invoice itself and reports it to the tax authority immediately or within a short deadline — unlike clearance, no prior approval is needed                                                       |
| **Two-corner model**   | Direct exchange between supplier and buyer, with no intermediary                                                                                                                                                                                                        |
| **Three-corner model** | Exchange where supplier and buyer both connect to the same shared platform                                                                                                                                                                                              |
| **Four-corner model**  | Exchange where supplier and buyer each use their own service provider, and the two providers interoperate over a shared network such as [Peppol](/apps/peppol)                                                                                                          |
| **Five-corner model**  | A four-corner network with the tax authority as a fifth corner receiving a copy of each transaction (Singapore's InvoiceNow, Belgium from 2028)                                                                                                                         |
| **Hybrid model**       | Approach where a single file carries both a human-readable PDF and the structured XML embedded inside it (Factur-X, ZUGFeRD)                                                                                                                                            |
| **E-invoicing**        | Issuing, sending and receiving invoices as structured data that the recipient can process automatically — a PDF or a scanned image is not an e-invoice                                                                                                                  |
| **E-reporting**        | Obligation to send transaction, invoice or payment data to the tax authority, separately from delivering the invoice to the buyer                                                                                                                                       |
| **Fiscalization**      | Legal and technical controls — certified software, signed records, receipt codes, cash registers — that make sales tamper-evident, historically aimed at the retail sector                                                                                              |
| **Mandate**            | Legal obligation, with a defined scope and effective date, to issue or receive e-invoices or to report transaction data                                                                                                                                                 |
| **Grace period**       | Window after a mandate takes effect during which penalties are suspended so businesses can adapt (Poland during 2026)                                                                                                                                                   |
| **VAT gap**            | Difference between the VAT theoretically due and the VAT actually collected — the usual policy justification for a CTC mandate                                                                                                                                          |
| **Interoperability**   | Ability of two systems to exchange documents without a bespoke agreement, achieved through a shared semantic model, syntax and transport                                                                                                                                |

|                                            |                                                                                                                                                                                         |
| ------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Correction**                             | Process of fixing errors in previously issued documents. Most regimes forbid editing the original and require a corrective document or a cancellation record instead                    |
| **Credit Note**                            | A document issued to correct or cancel a previously issued invoice                                                                                                                      |

| **Cancellation**                           | Withdrawal of a document that has already been cleared or reported, usually within a deadline and sometimes requiring the buyer's consent                                               |
| **Simplified invoice**                     | Reduced-content invoice permitted below a value threshold, typically without the buyer's tax details — the receipt of most regimes                                                      |
| **Self-billing**                           | Arrangement where the buyer issues the invoice on the supplier's behalf under a prior agreement, with the supplier remaining liable for its content                                     |
| **Tax point**                              | The date that fixes which period a transaction belongs to and which rate applies — often the date of supply rather than the invoice date                                                |
| **Reverse charge**                         | Mechanism that shifts liability for VAT to the buyer, so the supplier invoices without tax and the buyer self-assesses it                                                               |
| **Digital Signature**                      | Cryptographic signature that binds a document to its issuer and proves it has not been altered since                                                                                    |
| **Qualified certificate**                  | Certificate issued by a trust service provider under eIDAS, or by the tax authority itself, used to sign fiscal documents and authenticate to the platform                              |
| **Hash chain**                             | Technique that links each fiscal record to a hash of the previous one, so removing or altering a record breaks the sequence (VERI\*FACTU, TicketBAI, ZATCA's Previous Invoice Hash)     |
| **QR Code**                                | Quick Response code printed on or attached to a document, encoding the identifiers needed for a buyer or inspector to verify the record with the tax authority                          |
| **Offline mode**                           | Procedure for issuing a legally valid document while the tax authority platform is unreachable, with a deadline for submitting it afterwards (Poland's offline24, VERI\*FACTU, Croatia) |
| **Integrity, authenticity and legibility** | The three properties EU VAT law requires be guaranteed for an invoice throughout its life, whatever the technical means used                                                            |
| **Retention period**                       | Legally defined number of years — typically between six and eleven — for which documents must be kept, readable and available for inspection                                            |
| **Archiving**                              | Storing documents in their original structured form for the retention period, often with additional requirements on location and probative value                                        |
| **Audit trail**                            | Record of what happened to a document — submissions, responses, corrections — that lets an auditor reconstruct events after the fact                                                    |
