Kintsugi automates the full sales tax lifecycle for fast-scaling businesses using AI-driven compliance tools. It tracks real-time tax exposure, handles registrations and filings, and integrates with platforms like Shopify and QuickBooks. Built by former leaders at Facebook and Atlassian, the platform eliminates manual work and reduces compliance errors.
Why Sales Tax Is Still a Nightmare for Modern Brands
In 2018, the Supreme Court ruling in South Dakota v. Wayfair, Inc. changed how businesses handle sales tax across the United States. Brands are now responsible for collecting and remitting sales tax in any state they sell to, even if they have no physical presence there. For digital-first businesses scaling across borders, this means managing compliance with more than 30 distinct tax jurisdictions, each with its own set of rules and deadlines.
This complexity has turned sales tax compliance into a bottleneck for growth. Teams spend time juggling spreadsheets, deciphering state laws, and checking if they owe tax in regions they’ve never visited. Missed deadlines and manual errors are common, resulting in unnecessary penalties and business risks. The administrative load has made it difficult for lean teams to maintain focus on core operations.
Kintsugi Steps In to Do the Dirty Work
Kintsugi is designed to automate the entire sales tax lifecycle. The platform replaces manual compliance workflows with AI-driven automation. It handles tax calculations, exposure monitoring, filing, remittance, and even registration—all from a centralized system.
By using Kintsugi, businesses no longer need to rely on external CPAs or spend hours researching tax obligations. The software provides real-time clarity into tax liabilities and syncs across the user’s finance stack. It is intended to work without ongoing manual input, letting operators set up and move on.
Kintsugi users can get started in minutes without entering payment details. The company provides a free nexus study and sales tax assessment to evaluate where a business might have obligations.
How It Actually Works — No Magic, Just Smart Engineering
The platform operates through a streamlined three-step workflow:
- Connect: Sync billing, payment, and HR systems with a few clicks.
- Register: Instantly detect where registration is required based on live transaction data.
- Remit: Automate filings and payments to relevant jurisdictions.
Kintsugi’s engine supports real-time exposure monitoring, identifying where a business crosses nexus thresholds and must register. Its tax engine adapts dynamically to law changes across different states. Instead of using static rules, the system updates compliance obligations using current data.
The platform includes one-click filings, eliminating the need to track deadlines manually. Users receive insights on where they owe tax and when filings are due. By integrating directly with tools like Shopify, QuickBooks, and ERP systems, Kintsugi maintains accuracy across the full transaction lifecycle.
Built by Experts Who’ve Been in the Trenches
Kintsugi was co-founded by Pujun Bhatnagar, who serves as the company’s CEO. Prior to launching the platform, Bhatnagar worked as a Senior Machine Learning Engineer at Facebook, where he focused on vertical AI solutions. His experience with data-driven products informs Kintsugi’s approach to automating complex tax operations.
Jeff Gibson, the company’s CTO, brings more than 20 years of software development experience. At Atlassian, he led the Data Platforms team, building scalable systems used by global teams. At Kintsugi, Gibson is responsible for developing the core infrastructure that powers tax automation.
The product was built in direct response to the chaos observed post-Wayfair. Bhatnagar and the founding team experienced firsthand how burdensome tax compliance can be during business expansion. The company’s mission is to remove tax as a blocker to growth.

Why Fast-Growing Startups and Finance Teams Are Jumping In
Kintsugi is already used by a wide range of teams, from startup founders to dedicated finance departments. Users cite time savings, a decrease in filing errors, and relief from constant regulatory stress. Businesses no longer need to worry about filing late or figuring out whether they owe tax in a new state.
Teams benefit from the following:
- Reduction in sales tax preparation time by up to 75%
- Lower error rates due to AI-driven calculations
- Visibility into real-time obligations across jurisdictions
- No-code setup and integration with financial systems
Customers describe Kintsugi as a tool that helps them understand exposure in minutes, replacing anxiety with clarity. For Shopify sellers in particular, the ability to operate without external accountants is cited as a major advantage.
How Kintsugi Stands Out in a Crowded Market
Kintsugi positions itself as an alternative to established tax tools like Avalara, TaxJar, StripeTax, Zamp, and Numeral. Unlike static rule-based systems, Kintsugi’s automation engine adapts in real time to law changes and thresholds.
The platform is tailored for founders, operations leaders, and finance teams—not just traditional accountants. Its focus on user-friendly setup and clear insights makes it appealing to teams without deep tax knowledge.
Integration is another differentiator. Kintsugi connects easily with platforms beyond e-commerce, including broader billing and payment systems. This versatility ensures businesses can continue scaling without reworking their compliance processes.
Why Automating Sales Tax Might Be the Smartest Move You Make This Year
With laws continuing to evolve and regulatory complexity increasing, compliance is becoming more difficult to manage manually. Teams already stretched thin by growth demands can’t afford to miss filing deadlines or operate without visibility into tax exposure.
Kintsugi helps businesses avoid surprises, missed filings, and backdated penalties. By handling compliance in the background, it gives operators room to focus on scaling rather than sorting through tax documents.
