What does Kintsugi do?

Kintsugi is an AI-powered platform that automates the entire sales tax lifecycle for online businesses. It connects to your billing, payment, and ERP systems to monitor transactions in real time, calculates the correct tax liability based on precise product rules, and handles the filing and remittance process. The goal is to eliminate manual work, reduce compliance errors, and prevent unexpected fees from tax authorities.

The tool uses AI specifically for real-time exposure monitoring, automated product classification, and address validation. This means it can instantly show how a new sale affects your tax liability and ensure you're applying the most accurate tax rules for each item you sell. It integrates with over 40 common business platforms and supports tax obligations in more than 100 countries, promising a unified dashboard for global tax management.

This software is built for ecommerce brands, SaaS companies, and their finance teams who are tired of spreadsheet calculations and the administrative burden of multi-jurisdiction tax compliance. It's practical for businesses scaling into new markets, dealing with complex product taxability rules, or simply wanting to ensure they never face a penalty for a missed filing or incorrect calculation.
