Yes. The UK government has confirmed a four-corner decentralised exchange model, with strong indications that Peppol will be the core interoperability network. SMARTeIS is a fully Peppol-certified Access Point, supporting Peppol BIS Billing, UBL and EN 16931 formats out of the box. This makes SMARTeIS ready for the 2029 HMRC mandate from day one, with no architectural changes required as final technical standards are published at Budget 2026.

The UK is adopting a decentralised market-led model built on globally recognised standards. SMARTeIS supports every format aligned with the upcoming UK regime – Peppol BIS Billing, UBL 2.1, EN 16931, CII and XML – alongside legacy EDI formats your trading partners may still use. This ensures first-time acceptance across HMRC, public sector buyers via NHS Shared Business Services, and private trading partners regardless of their format preference.

Making Tax Digital (MTD) has required digital VAT record-keeping in the UK since 2019, and HMRC has confirmed the 2029 e-invoicing mandate will build on the MTD foundation. SMARTeIS automatically synchronises structured invoice data with MTD-compliant bookkeeping software, generates digital audit trails, and supports the seamless transition to future Real-Time Reporting (RTR) that HMRC has indicated will follow once e-invoicing is well established.

SMARTeIS is architected with UK data sovereignty as a core principle. All UK e-invoicing data is processed and stored exclusively within UK or EU-based data centres, ensuring full compliance with UK GDPR, the Data Protection Act 2018, the ePrivacy Directive, and NIS2 cybersecurity requirements. The platform includes encrypted data processing, audit trails, configurable retention policies, and undergoes regular third-party audits for ISO 27001 and SOC 2 Type II compliance.

Yes. SMARTeIS supports centralised HMRC-compliant management of multiple legal entities, each with its own UK VAT number, MTD profiles and Peppol Access Point routing. For businesses also operating in France, Germany, Belgium, Spain, or Italy, the platform automatically applies the correct country-specific e-invoicing format and routing logic per entity, giving headquarters consolidated visibility while maintaining local compliance with each tax authority.

Yes. Under the Windsor Framework, Northern Ireland continues to follow EU VAT rules for goods, meaning supplies to the EU from Northern Ireland will fall under ViDA Digital Reporting Requirements from 1 July 2030 – fifteen months after the UK’s 2029 mandate. SMARTeIS includes pre-configured profiles for Northern Ireland businesses, handling both the UK domestic e-invoicing regime and ViDA-compliant cross-border reporting through a single platform.

Yes. SMARTeIS integrates seamlessly with your existing ERP infrastructure without requiring core system changes. Pre-built connectors are available for SAP, Oracle, Microsoft Dynamics, Sage, Odoo, and others. Your finance teams continue working in familiar ERP interfaces while SMARTeIS handles Factur-X conversion, DGFiP validation, digital signatures, and transmission to French tax authorities and trading partners.

HMRC regulatory updates are included at no additional cost. SMARTeIS maintains a dedicated Compliance Center that continuously monitors HMRC announcements, Budget updates, Peppol Authority specifications, and ViDA directive developments. As the UK’s e-invoicing roadmap is finalised through 2026–2028, the platform’s validation engines, format templates, and routing logic are updated automatically and deployed to all clients without downtime – keeping your solution future-ready.

SMARTeIS includes a comprehensive UK e-invoicing archive aligned with HMRC’s statutory requirements – six years for VAT records under the VAT Act 1994, and six years for company records under the Companies Act 2006. Invoices are stored in their original Peppol BIS or UBL formats alongside HMRC submission responses, digital signatures, and full transmission logs. All archived documents are tamper-proof, fully searchable, and instantly retrievable for HMRC inspections.
