Full CTC document support including TDD (Tax Data Document) & TDS (Tax Data Structure) receiving capabilities, ensuring compliance with the latest regulatory schemas.
Arratech CTC Suite - Trusted Infrastructure for Digital Tax Control Networks
Enabling secure, real-time tax control for the digital economy
Modern tax compliance goes beyond traditional e-invoicing.
As governments adopt Continuous Transaction Controls (CTC) — real-time validation, clearance, and reporting — they face the challenge of building secure, scalable infrastructures that can handle billions of transactions, stay compliant with fast-changing regulations, and integrate seamlessly with existing tax systems. Arratech empowers tax authorities and public administrations to deploy next-generation CTC networks, from high-volume domestic reporting to cross-border interoperability through Peppol and other global frameworks.
Changes introduced under ViDA are driving the need for next-generation CTC networks
Enormous transaction volumes
Rapidly expanding transaction volumes, with millions of invoices and reports which must be validated instantly.
Complex interoperability
Fragmented standards (Peppol BIS, TDD/TDS, CTC schemas) make seamless exchange difficult and creates increased complexity.
Regulatory pressure
To adapt to ViDA and national mandates, tax agencies need to guarantee compliance, authenticity, and data sovereignty.
Integration complexity
Legacy tax management systems struggle to interact with modern real-time networks and Digital Reporting Requirements (DRR).
What is the Peppol 5-corner model?
The Peppol 5-corner model adds real-time tax control to the proven 4-corner model used for e-invoicing. Each participant has a clear role and Arratech’s technology makes their interaction seamless, compliant, and scalable.
Corner 1 (C1) - Sender (Supplier)
Creates and issues the e-Invoice in a compliant, structured format.
Corner 2 (C2) - Sender’s Access Point (AP)
Powered by the sender's Peppol service provider, uploads the e-Invoice into the Peppol network.
Corner 3 (C3) - Receiver’s Access Point (AP)
Receives and checks the invoice, ensuring it is Peppol-compliant before delivering it securely to the buyer.
Corner 4 (C4) - Receiver (Buyer)
Gets the validated invoice directly into their ERP or accounting system format for automated booking, approval, and payment.
Corner 5 (C5) - Government / Tax Authority
Powered by Arratech’s C5 aggregation Access Point, which validates and reports invoices in real time to the relevant tax authority, providing instant visibility and enabling control with real-time e-reporting, validation, and fraud prevention.

FAQs
What is the Five-Corner Model?
The Five-Corner Model adds a fifth party—usually a tax authority or regulatory platform—to the traditional Four-Corner setup. It enables the transmission of business documents (like e-invoices) while also fulfilling real-time reporting requirements to the government.
Flow of the Five-Corner Model
- Sender (Corner 1): The business initiating an invoice or document.
- Sender’s Access Point (Corner 2): Validates and forwards the document into the network to C3.
- Receiver’s Access Point (Corner 3): Receives document and delivers the cleared document to the receiver in their designated format.
- Receiver (Corner 4): The final recipient of the document (business or public entity).
- Regulatory Gateway (Corner 5): A platform, often run or certified by the government, that checks or clears the document (e.g., for VAT compliance).
Where is data stored, and is it compliant with local regulations?
All data processed within our ViDA-aligned solutions is stored in certified, high-security data centers that meet the highest standards for information protection, including ISO 27001 and SOC 2 Type II certifications.
For EU operations, all data is hosted within the European Union, ensuring full compliance with the General Data Protection Regulation (GDPR) and applicable local data sovereignty laws. Each dataset — including transactional, analytical, and audit data — is segregated according to jurisdictional boundaries and customer requirements.
For non-EU or multinational deployments, we provide region-specific storage configurations to ensure that data residency adheres to the legal and regulatory frameworks of each geography (e.g., local tax authority mandates, electronic invoicing laws, and data retention policies). This includes ensuring that any cross-border data transfer mechanisms comply with approved safeguards such as Standard Contractual Clauses (SCCs) or equivalent local frameworks.
In practice, this means that:
- Each customer’s data remains physically and logically contained within the required jurisdiction.
- Access and processing policies are configured to align with local regulatory requirements.
- Data handling, retention, and encryption are enforced according to both customer and legislative mandates.
This approach ensures that ViDA compliance and local data sovereignty obligations are fully maintained while enabling secure, scalable analytics and reporting capabilities across multiple regions.
Is your solution compliant with international e-invoicing standards?
Yes, our access point is certified to operate in over 40 countries, ensuring compliance with networks like Peppol and DBNAlliance. This allows you to offer compliant e-invoicing services globally without the need for multiple integrations.
What is ViDA?
VAT in the Digital Age (ViDA) is a European Commission legislative initiative aimed at transforming the administration of VAT across the EU through digitalization. It introduces a unified framework for real-time digital reporting, e-invoicing, and platform economy VAT rules, replacing fragmented national systems with a standardized, interoperable architecture.
Core Components of ViDA
- Digital Reporting Requirements (DRR):ViDA mandates near real-time electronic reporting of intra-EU B2B transactions based on structured, machine-readable e-invoices aligned with EN 16931. This enables tax administrations to collect transactional data continuously rather than through periodic VAT returns.
- Mandatory E-Invoicing Framework:The initiative removes the need for prior authorization of e-invoicing mandates by member states, promoting interoperability and reducing compliance complexity. Intra-EU transactions will be reported within two days of invoice issuance, significantly improving auditability.
- Single VAT Registration (SVR):Businesses operating cross-border will benefit from simplified VAT registration through a single EU-wide identification, reducing administrative overhead.
Implications for Tax Authorities
For tax administrations, ViDA represents a major leap toward data-driven VAT oversight:
- End-to-end transaction visibility through structured data exchange in real or near real time.
- Automated anomaly detection using standardized invoice and transaction data models.
- Enhanced fraud prevention by addressing missing trader intra-community (MTIC) fraud via early data access.
- Interoperability across member states, allowing cross-border analytics and collaborative enforcement.
Technically, ViDA establishes a common EU digital reporting infrastructure compatible with national systems, leveraging APIs and standardized XML/UBL data formats. It aligns with ongoing CEN and eIDAS frameworks to ensure secure, verifiable data transmission and identity authentication.
In Summary
ViDA transforms VAT management from declarative reporting to continuous transaction-level supervision, enabling Tax Authorities to operate on a proactive, analytics-driven compliance model while simplifying legitimate business processes.
