What counts as a filing?

Starter is priced per filing or registration, starting at $75 each. A filing is a return Kintsugi files and remits for you, and a registration is a tax registration Kintsugi completes for you. Exposure monitoring, alerts, and CSV transaction imports are part of the Free plan, and there are no transaction fees.

Is the Free plan really free?

Yes. The Free plan is $0 with no credit card required. It includes global exposure (nexus) monitoring across the US and 100+ countries, historical liability auditing, nexus threshold alerts, AI-powered product categorization, address validation, Kin, CSV imports, and no-code integrations. Registering, filing, and remitting start on the Starter plan.

Do I have to sign a long-term contract?

No. Kintsugi has no long-term contract lock-in. Starter is billed per filing or registration, and Premium is flat-rate pricing with volume-based discounts.

Are there implementation or onboarding fees?

No. There are no onboarding fees and no transaction fees. Starter includes onboarding assistance, and Premium adds dedicated onboarding and account teams with SLA-backed support.

What is the Kintsugi Guarantee?

The Kintsugi Guarantee is included with Premium. It is our promise that your sales tax, VAT, and GST compliance gets done right: we catch issues before you do, respond in hours, and if a calculation we made or a filing error of ours leads to penalties or interest, we pay it. The full terms are in your agreement.

How does Kintsugi compare to per-state pricing?

Kintsugi doesn't charge a subscription for each state. Exposure monitoring across every state is free, and on Starter you pay only for the filings and registrations Kintsugi handles, starting at $75 each. Premium moves to flat-rate pricing with volume-based discounts.

What our customers say

Yuki Kinoshita
Co-founder of Plufl
I'm glad I made the switch. Not only am I saving money right now, I'm also getting better service and accuracy. It's been a win-win for us to transition.
John Roman
CEO of Battlbox
This doesn’t feel like a vendor relationship. They actually care and it’s very apparent almost immediately after working with them.
Ben Perkins
Founder & CEO of &Collar
With Kintsugi, we stopped getting non-compliant emails from different states and districts. We save money and can really be hands-off, what a win. We matter enough to be able to know the team and feel confident that they’ll take care of us. Secondly, there are real cost savings that end up contributing to our bottom line.
Adam Klausner
President & COO, Symbiome
With our previous provider, I was tracking nexus myself and spending time on tasks like being on hold with the Secretary of State’s office, and my accountant and bookkeeper had to stay actively involved, but Kintsugi completely solved this problem by taking over these time-consuming tasks.
