About the Company

Fonoa

AI tax operating system for platforms

Fonoa builds an AI-powered tax operating system for multinational digital platforms, marketplaces, and SaaS businesses, with modules for tax ID validation, real-time tax determination across 190+ jurisdictions, e-invoicing, and returns on a shared data model with a single audit trail. Its platform enables end-to-end indirect tax automation by unifying calculation, invoicing, and filing on one system, now enhanced by integrating PwC’s Edge for VAT/GST reporting, e-filing, and analytics. This differentiates it from point solutions by offering a comprehensive, single platform for tax tasks across many jurisdictions and customers like Uber, Netflix, Booking.com, and Canva. The goal is to simplify and automate indirect tax compliance for digital businesses at global scale, reducing manual work and compliance risk.
