Kintsugi AI

Kintsugi automates your entire sales tax lifecycle: free nexus exposure monitoring, local, state, and country registrations, accurate tax calculation at checkout, filing, and remittance wherever you owe. Connect your store, and we handle the rest. 

We integrate directly with the platforms you already use: Shopify, BigCommerce, WooCommerce, Magento, Amazon, Walmart, QuickBooks, and more.

Sales Tax Compliance That Actually Works -- If your current tax solution is collecting but missing filings, slow on support, or nickel-and-diming you on every action, you're not alone. Most ecommerce brands outgrow their tax provider before they realize it. 

Our name, Kintsugi, comes from the Japanese art form of repairing something broken with gold to make it stronger – and that is exactly what we are doing with the broken sales tax system. The ecommerce brands we serve are growing stronger with a sales tax solution they can trust running smoothly in the background.
