What Kintsugi does
Kintsugi is a compliance platform that connects to a firm's accounting, billing, ecommerce, payment, and HR/payroll systems. Once connected, it continuously monitors sales, refunds, invoices, transactions, and workforce changes against economic and physical nexus thresholds across all US states and over 100 countries. It flags potential nexus events such as hiring a remote employee in a new state and calculates tax obligations in real time.
Integrations and data flow
Kintsugi integrates natively with QuickBooks Online and Xero. From QuickBooks it syncs customers, products, invoices, transactions, refunds, and exemptions and can calculate sales tax on invoices as they are created. From Xero it imports contacts, invoices, credit notes, line items, adjustments, and multi-currency transactions. The platform uses that synced data to classify products and line items so taxability and liability calculations are accurate across currencies and jurisdictions.
How it handles tax work
Calculations are rules‑based and deterministic, producing audit-ready answers. The platform layers AI for high-volume monitoring and transaction classification, but core tax math and final compliance decisions remain supported by Kintsugi's tax experts and human review. That combination is presented as audit-ready reporting and reconciliation.

Who Kintsugi is built for
Global scope and mobility
Beyond the US, Kintsugi covers VAT and GST requirements in 100+ countries. The platform also offers a mobile app on iOS and Android so firms can receive nexus alerts and monitor client compliance on the go.
Human support and commercial terms
Kintsugi emphasizes human support alongside automation: daily human updates train the platform's assistant and a support team is available for escalations. The service is offered without long-term contracts, giving firms flexibility to scale services by client needs.
Competitive context
Within fintech and tax compliance tools, Avalara and Zamp are presented as alternative vendors. Kintsugi differentiates on continuous nexus monitoring, integrated accounting syncs, built-in assistant, and end-to-end filing and remittance backed by human review.
Bottom line
Kintsugi combines continuous nexus monitoring, accounting integrations, deterministic tax calculations, AI-assisted classification, and human review to automate sales-tax and VAT/GST compliance across many jurisdictions. It aims to reduce manual portal work for firms and provide a single compliance view for managing multiple clients.
