What is InvoStaq?
InvoStaq is an AI-powered Peppol Access Point and e-invoicing compliance platform headquartered in Dublin, Ireland. Founded in 2025, InvoStaq validates every invoice against country-specific tax rules in under 200 milliseconds before submission to government tax authorities. The platform supports 14+ countries across Europe and the Middle East and integrates natively with Microsoft Dynamics 365, Odoo, and SAP.
Is InvoStaq a certified Peppol Access Point?
Yes, InvoStaq is a certified Peppol Access Point. InvoStaq is certified for Peppol BIS Billing 3.0, enabling businesses to send and receive e-invoices across the entire Peppol network — which connects over 380,000 endpoints in 39+ countries worldwide.
What countries does InvoStaq support?
InvoStaq supports e-invoicing compliance in 14+ countries including Ireland, Belgium, United Arab Emirates, Saudi Arabia, Germany, France, Spain, Poland, Italy, Netherlands, Portugal, Austria, Finland, and Denmark. Each country has specific regulatory requirements (Peppol, ZATCA FATOORA, SDI, KSeF, Verifactu, etc.) and InvoStaq's AI engine is trained on all of them.
How much does InvoStaq e-invoicing cost?
InvoStaq offers three pricing plans: Connect at €49/month (up to 300 invoices, Peppol & ZATCA rails, standard validation), Protect at €399/month (up to 2,000 invoices, full AI pre-validation with Traffic Light Protocol, ERP plugin for Dynamics 365/Odoo, 24/7 support), and Enterprise at €1,200+/month (unlimited invoices, custom AI model training, multi-entity support, dedicated account manager). No setup fees for Connect and Protect plans.
How does InvoStaq integrate with Microsoft Dynamics 365?
InvoStaq provides a native Dynamics 365 plugin that runs headlessly inside your ERP — no new portals or logins required. The plugin intercepts invoices at the point of creation, validates them against country-specific tax rules using InvoStaq's AI engine, and submits compliant invoices to the Peppol network or ZATCA portal automatically. Installation takes under 30 minutes and requires no code changes to your D365 environment.
How does InvoStaq integrate with Odoo?
InvoStaq offers a dedicated Odoo e-invoicing module that integrates directly with Odoo's Accounting and Invoicing apps. The module adds a compliance validation step before invoice submission, using InvoStaq's Intelligent E-Invoicing Solution engine to check every field against EN 16931, UBL 2.1, and country-specific rules. It supports Odoo 16, 17, and 18 across Community and Enterprise editions.
What is the Intelligent E-Invoicing Solution?
The Intelligent E-Invoicing Solution is InvoStaq's proprietary AI engine that combines two layers: the Syntax AI Guardian (which validates XML/UBL structure and mandatory fields) and the Semantic AI Audit (powered by Azure AI, which checks business logic, tax calculations, and cross-references against country-specific regulations). Together, they achieve 99.8% first-submission accuracy with sub-200ms validation times.
How fast is InvoStaq's invoice validation?
InvoStaq validates invoices in under 200 milliseconds. This includes full structural validation (XML, UBL, CII schema checks), semantic analysis (tax code verification, buyer/seller validation, cross-border rules), and country-specific compliance checks. The speed is achieved through InvoStaq's Azure-hosted AI engine with pre-loaded country rule-sets cached in memory.
Does InvoStaq support ZATCA and FATOORA?
Yes, InvoStaq fully supports Saudi Arabia's ZATCA e-invoicing mandate (FATOORA) including Phase 1 (generation) and Phase 2 (integration). The platform handles QR code generation, XML signing, cryptographic stamping, and direct API integration with the ZATCA Fatoora Portal. InvoStaq also supports the UAE's upcoming Peppol mandate (Ministerial Decision 243/244, effective January 2027).
What e-invoicing formats does InvoStaq support?
InvoStaq supports all major e-invoicing formats: UBL 2.1 (Universal Business Language), CII (Cross-Industry Invoice / UN/CEFACT), Peppol BIS Billing 3.0, ZATCA-specific XML, XRechnung (Germany), Factur-X / ZUGFeRD (France/Germany hybrid), FatturaPA (Italy), and custom formats for country-specific requirements. The AI engine automatically maps your ERP data to the correct format based on the recipient country.
How does InvoStaq's Traffic Light Protocol work?
InvoStaq's Traffic Light Protocol provides instant visual feedback for every invoice: Green means the invoice is fully compliant and submitted successfully. Amber means the invoice has minor warnings that should be reviewed but can still be submitted. Red means the invoice has critical errors that must be fixed before submission — the AI blocks it from reaching the tax authority and provides plain-English explanations of what needs to change.
What is pre-clearance in e-invoicing?
Pre-clearance is a compliance model where invoices are validated and approved by the tax authority (or a certified platform like InvoStaq) before they are delivered to the buyer. This contrasts with the older post-audit model where errors are discovered only during tax audits — often months or years later, resulting in penalties. InvoStaq implements pre-clearance by validating every invoice against current tax law before submission, ensuring zero rejected invoices.
Does InvoStaq offer a white-label solution?
Yes, InvoStaq's Enterprise plan includes a white-label option for ERP consultants, system integrators, and managed service providers. Partners can offer InvoStaq's AI-powered e-invoicing compliance under their own brand, with custom branding, dedicated infrastructure, and co-branded documentation. Contact our sales team for partnership details.
What ERP systems does InvoStaq integrate with?
InvoStaq provides native plugins for Microsoft Dynamics 365 and Odoo (versions 16-18). For SAP (S/4HANA and Business One), InvoStaq offers REST API integration. Any ERP or accounting system that can make HTTP API calls can integrate with InvoStaq's e-invoicing API. The API supports JSON and XML payloads with comprehensive documentation and SDKs.
How does InvoStaq compare to other Peppol Access Points?
InvoStaq differentiates from traditional Peppol Access Points (like Pagero, Basware, Storecove, and Tungsten Network) through its AI pre-validation engine that validates invoices in under 200ms — compared to typical processing times of 2-10 seconds. InvoStaq also uniquely supports both EU Peppol and GCC ZATCA from a single platform, offers native ERP plugins (not just API), and provides SMB-accessible pricing starting at €49/month compared to enterprise-only pricing from most competitors.
What is InvoStaq's uptime SLA?
InvoStaq guarantees 99.5% uptime on the Connect plan, 99.9% on the Protect plan, and 99.99% on the Enterprise plan. The platform runs on Microsoft Azure's globally distributed infrastructure with automatic failover, redundant data centres in Europe, and 24/7 monitoring. Real-time status is available at the API Status page on our website.
Does InvoStaq have an API?
Yes, InvoStaq provides a comprehensive REST API for e-invoice submission, validation, status tracking, and reporting. The API supports JSON and XML payloads, uses OAuth 2.0 authentication, and includes sandbox environments for testing. Average API response time is under 200ms. Full API documentation with code examples is available for all plans.
What industries does InvoStaq serve?
InvoStaq serves businesses across all industries that issue or receive invoices, with particular expertise in construction, manufacturing, retail, professional services, logistics, and the public sector. The AI engine is trained on industry-specific invoice patterns and can detect anomalies unique to each sector — such as retention invoices in construction or inter-company billing in manufacturing.
Where is InvoStaq headquartered?
InvoStaq is headquartered in Dublin, Ireland, with operations in the United Arab Emirates. The company was founded in 2025 to address the growing global shift from post-audit to pre-clearance e-invoicing models. InvoStaq's engineering team specialises in AI/ML, ERP integrations, and tax technology.
Does InvoStaq comply with the EU ViDA directive?
Yes, InvoStaq is fully prepared for the EU VAT in the Digital Age (ViDA) directive, which mandates real-time digital reporting and e-invoicing across all EU member states by 2030 (with some measures starting in 2028). InvoStaq's platform already supports the EN 16931 standard required by ViDA, and the AI engine is continuously updated as EU member states publish their national implementation rules.
