Invaq
Bridges enterprise ERP systems (SAP, Oracle, Odoo) to the UAE Peppol e-invoicing compliance network using a high-performance Rust parser to output PINT-AE XML.
Project Overview & Objectives
Invaq is a mission-critical compliance middleware engineered specifically to meet the UAE Federal Tax Authority (FTA) e-invoicing standards. The mandate requires every commercial invoice transaction to be generated, validated, and signed in the specialized UBL PINT-AE XML format before routing it to Peppol Access Point nodes. Organizations running monolithic ERP systems like SAP or Oracle cannot easily adapt their database architectures to compile these precise compliance formats. Invaq acts as a high-performance middleware layer. Built in Rust for maximum speed and safety, it ingests raw JSON outputs from ERP systems, maps the data points to the PINT-AE specification, applies cryptographic signatures, and submits the finalized XML document in under 5 milliseconds. This plug-and-play architecture enables compliance without modifying the underlying ERP code.
Core Tech Stack
- Rust Parser
- Peppol AP Client
- ERP Connectors
- UBL PINT-AE XML
- SHA-256 Signing
The Challenge
The UAE e-invoicing mandate requires organizations to validate and submit electronic invoice transactions to Federal Tax Authority (FTA) channels in the strict PINT-AE format. Enterprise ERP engines cannot natively structure or cryptographically sign these payloads, creating massive regulatory compliance risk.
Our Solution
We engineered Invaq, a high-speed middleware compliance layer. Built in Rust, Invaq intercepts raw invoice JSON telemetry from ERP systems, converts and validates it into UBL PINT-AE XML in under 5 milliseconds, applies secure digital signatures, and routes documents through approved Peppol Access Point channels for real-time clearance.
