What is Kintsugi?

Frequently asked questions about Kintsugi
What is Kintsugi and what does it do?
Kintsugi is an AI-native sales tax automation platform built for high-growth B2B and e-commerce businesses. It automates the entire sales tax lifecycle including nexus monitoring across all 50 states and 50+ countries, automatic state registration when you trigger nexus, AI-powered product classification, precise tax calculations, AutoFile for automatic return filing, and remittance of taxes to the appropriate authorities.
How does Kintsugi's pricing work?
Kintsugi uses transparent pay-per-filing pricing. It's free to start - you can connect your systems and see your tax exposure without a credit card. Then you pay $100 per state for each filing and registration you make. Custom plans are available for higher volume businesses. There are no hefty onboarding fees or mandatory annual contracts.
What integrations does Kintsugi support?
Kintsugi connects to the tools B2B companies actually use including Stripe, Chargebee, QuickBooks, Shopify, BigCommerce, Amazon, WooCommerce, and NetSuite. Setup is no-code and most companies are live in a day. There's also an open API for everything else.
How does Kintsugi's AI product classification work?
Kintsugi's AI automatically classifies your products and applies the correct tax treatment. Different products get taxed differently - SaaS is taxable in some states but not others, and digital goods have separate rules. Kintsugi built their classification engines in-house rather than relying on generic LLMs, which makes them significantly more accurate than competitors.
What is Kin and how is it different from other AI tax tools?
Kin is the AI assistant built directly into Kintsugi that gives instant, cited answers to your real sales tax, VAT, and GST questions grounded in your actual data. Unlike other AI tools, Kin shows its work - every answer cites the transactions, jurisdictions, and rules behind it because in tax compliance a confident wrong answer is worse than no answer at all.
Does Kintsugi support international tax compliance?
Yes, Kintsugi covers sales tax, VAT, and GST across the US and 30+ countries including Canada, the UK, Australia, Germany, France, and the rest of the EU. The platform monitors nexus and handles compliance globally.
How does Kintsugi handle tax remittance payments?
Kintsugi simplifies sales tax payments by handling the entire remittance process to appropriate tax authorities. Currently Kintsugi only supports ACH (Automated Clearing House) payments - credit card payments are not supported. You add your bank details during onboarding and Kintsugi automatically withdraws necessary funds to remit sales tax to correct jurisdictions.
What happens if Kintsugi calculates a different tax amount than my billing system?
Kintsugi uses a dynamic approach for remittance. If both Kintsugi's calculation and your integration's calculation are positive, Kintsugi remits the greater amount. This method ensures sales tax remittance is 100% compliant and reduces the risk of underpayment of liabilities.
How quickly can I get started with Kintsugi?
Most companies are live in just one day. Setup is no-code - you connect your billing, e-commerce, or accounting systems through Kintsugi's integrations and you can immediately see your tax exposure. You don't need a sales call or lengthy onboarding process.
Who is Kintsugi built for and who should not use it?
Kintsugi is built for B2B and SaaS companies selling across multiple states (especially past $500K ARR), e-commerce businesses with multi-state or international sales, and finance/RevOps teams tired of manual tax calculations. If you're a local business selling in just one state, Kintsugi is probably overkill for your needs.
