About
Kintsugi is an intelligent sales tax automation and compliance platform built for ecommerce and SaaS businesses. Powered by AI, Kintsugi removes the complexity of managing sales tax, VAT, and GST obligations across jurisdictions — letting businesses focus on growth rather than compliance headaches. The platform provides real-time nexus exposure monitoring, automatically detecting when a business crosses economic nexus thresholds in any U.S. state or international market. Once nexus is identified, Kintsugi handles state registration with a single click, applies the most precise tax rules to every transaction using automated product classification and address validation, and collects the correct tax at checkout. Filing, remittance, and reconciliation are fully automated, meaning businesses never miss a deadline or overpay. Exemption certificate management is built in, and the AI continuously optimizes tax treatment based on product type and customer location. Kintsugi integrates with 40+ billing, payment, HR, and ERP systems — including popular ecommerce and SaaS platforms — making setup fast and data sync seamless. A free exposure study is available with no credit card required, giving businesses instant visibility into their tax risk before committing to a plan. Trusted by businesses in 106 countries, Kintsugi is ideal for small businesses, scaling startups, and finance teams who need accurate, automated tax compliance without hiring dedicated tax counsel.
