Kintsugi

Kintsugi is an AI-powered sales tax, VAT, and GST automation platform designed to eliminate the complexity and risk of tax compliance for modern businesses. Its core value proposition is providing a fully automated, end-to-end solution that monitors nexus obligations, calculates taxes in real time across transactions, and handles the entire filing and remittance process, thereby saving significant time and reducing costly errors.

Key features: The platform continuously monitors economic nexus thresholds across all relevant jurisdictions to alert businesses of new filing obligations. It performs real-time tax calculations using AI for address validation and product categorization to ensure accuracy. Kintsugi automates the preparation and submission of tax returns, supports voluntary disclosure agreements and reseller certificate management, and offers error insurance for peace of mind. It also handles complex scenarios like back taxes, state registrations, and refunds or amendments.

What sets Kintsugi apart is its deep AI integration, branded as TaxGPT, which goes beyond simple rate lookup to intelligently interpret tax laws and apply them to specific transactions and business models. Technically, it offers robust APIs and pre-built, seamless integrations with major e-commerce and financial platforms like Shopify, Stripe, Chargebee, QuickBooks, and BigCommerce, creating a unified compliance layer across a company's tech stack.

Ideal for e-commerce brands, SaaS companies, and service providers operating in multiple states or countries, especially those experiencing rapid growth where manual tax management becomes unsustainable. It is particularly valuable for B2B SaaS and fintech companies dealing with complex tax rules for digital products and services, as well as any online seller needing to navigate the patchwork of US sales tax laws or international VAT/GST regulations.

Pricing starts with a free plan for basic features, with paid plans beginning at $100 per month for advanced automation, higher transaction volumes, and full-service filing, scaling based on the complexity and scale of the business's operations.
