Kintsugi connects to the platforms you're already using to run your business: billing, ecommerce, ERP, and HR/payroll. From there, it manages your sales and use tax compliance end to end: monitoring where you owe, registering you in new jurisdictions, calculating and collecting the right tax, filing and remitting on time, and resolving whatever slips through.
Sales tax compliance in 100+ countries
Trusted by 7,000+ businesses
Kintsugi Intelligence constantly supports exposure monitoring, product tax classification, address validation, and workflow optimization: none of it touches a filing or a dollar. Your approval is required at all the critical points: approving product categories, registering in new jurisdictions, and completing back filings.
Platform AI
Runs continuously in the background: exposure monitoring, product tax classification, address validation, and workflow optimization. This is what powers everything described on this page.
Your AI Assistant
AI assistant built into the product that answers questions about your compliance, grounded in your own compliance data.
01 · Connect
Connect the platforms you're already using to run your business: billing, ecommerce, ERP/accounting, and HR/payroll. Kintsugi pulls transactions, customers, products, and more, without changing your source data. For some platforms, Kintsugi calculates tax directly on your invoices and orders at checkout, and even writes your returns back to the general ledger. Setup requires no code.
02 · Monitor
Track economic and physical nexus (the threshold that creates a tax obligation in a jurisdiction) across every jurisdiction you sell into: ongoing revenue and transaction thresholds, physical presence from inventory or remote employees, and the international VAT/GST registration thresholds that often catch US-based sellers going global. Alerts fire as you approach a threshold, not after you've crossed it. This monitoring is free for every customer.
03 · Register & collect
When you cross a threshold, Kintsugi can register on your behalf and tell you exactly what's needed from your side. Once registered, Kintsugi helps you enable tax calculation everywhere you need it, with real-time calculation available on some platforms.
04 · File & remit
Returns are generated automatically and available for your review before automatically filing to ensure you're always on time. Kintsugi handles remittance and hands back a confirmation record for every filing, including zero returns, consolidated returns, and prepayments.
Kintsugi also tracks use tax exposure (the buy-side liability from out-of-state or under-taxed purchases) as its own Use Tax view.
05 · Support
Jurisdiction notices land in Kintsugi Mail (virtual and physical), where they're triaged and routed for response. If you're behind somewhere, back filing and Voluntary Disclosure Agreements bring you current. The Kintsugi Guarantee backs the filings Kintsugi makes on your behalf. Every step along the way is captured as an auditable record: sourced determinations, traceable filings.
Built for 100+ countries, not bolted onto US sales tax
Kintsugi handles sales tax, VAT, and GST across 100+ countries: registration, calculation, and filing, with a clear understanding of where each of those three means something different by market, and where fiscal-representation requirements change how coverage actually works there.
