E-Invoicing / Glossary

E-invoicing glossary

The recurring jargon across e-invoicing mandates, in plain terms — from clearance models and Peppol to the acronyms behind each country's system.

Access Point / Service ProviderASP
An accredited provider that transmits e-invoices on your behalf and, in some regimes, reports to the authority. Required in models like the UAE's PINT AE.
Approved Platform (plateforme agréée)
Formerly commonly referred to as PDP. A state-registered provider in France's model that transmits invoices and reports data on a business's behalf.
CFDI
Comprobante Fiscal Digital por Internet — Mexico's e-invoice, generated through an authorised PAC and cleared by the SAT before delivery (current version 4.0).
Clearance modelCTC
A Continuous Transaction Controls model where the tax authority validates (clears) an invoice before or at the moment it is issued. India, Saudi Arabia, Mexico and Brazil use variants of this.
Decentralised CTC & ExchangeDCTCE
A model where accredited providers exchange invoices and report data to the authority in parallel, without a single central clearance point. The basis of Peppol five-corner setups.
Digital Reporting RequirementsDRR
Near-real-time reporting of transaction data to the tax authority, alongside or instead of periodic VAT returns. A core element of ViDA.
EN 16931
The European semantic standard defining the core data model of an electronic invoice. The reference standard for ViDA and most EU national mandates.
Fawtara
Oman's e-invoicing system, built on the Peppol framework, with a phased rollout from 2026.
Five-corner model
A Peppol arrangement where sender, sender's provider, receiver's provider, receiver, and the tax authority each play a role — the authority being the fifth corner.
Hermes
A platform provided by the Belgian government allowing businesses to send structured e-invoices to Belgian customers who are not yet connected to the Peppol network.
IRP / IRN
India's Invoice Registration Portal and the Invoice Reference Number it issues — an invoice is only valid under GST e-invoicing once it carries a registered IRN.
KSeF
Poland's National e-Invoice System — a central platform that receives structured FA(3) invoices and assigns each a KSeF number.
Master data
The reference data behind every invoice — customer and vendor tax IDs, product/service tax codes, and addresses. Its quality is the single biggest determinant of e-invoicing readiness.
MyInvois
Malaysia's e-invoicing platform operated by LHDN, which validates invoices in real time.
NF-e / NFS-e
Brazil's electronic invoices for goods (NF-e) and services (NFS-e) — XML documents pre-cleared by the tax authority.
PAC
Proveedor Autorizado de Certificación — an authorised provider in Mexico that certifies and stamps CFDIs on behalf of the SAT.
Peppol
An international framework and network for exchanging electronic documents through accredited Access Points. Increasingly adopted for e-invoicing beyond its European origin.
PINT AE
The UAE's Peppol-based e-invoicing specification, exchanged through Accredited Service Providers.
Post-audit
The traditional model where invoices are exchanged freely and the tax authority audits them later. Being phased out as mandates arrive.
ViDA
VAT in the Digital Age — the EU package moving intra-EU B2B transactions to structured e-invoicing and digital reporting, with the main obligation from July 2030.
ZATCA / FATOORA
Saudi Arabia's Zakat, Tax and Customs Authority and its e-invoicing programme (FATOORA), now in the Phase 2 integration/clearance stage rolled out by waves.
