Understanding Kintsugi Plans and Billing
See what each plan includes, how billing works, and how to upgrade when you are ready.Updated 6 days ago
Kintsugi has three plans: Free, Starter, and Premium. This guide explains what each plan includes, how each one is billed, and how to move to a different plan when your business grows. For the most current pricing and a full feature comparison, see the Kintsugi pricing page.
The Three Plans at a Glance
Plan | Price | Best for |
|---|---|---|
Free | $0, no credit card required | Seeing your sales tax exposure across the US and 100+ countries before you commit to anything |
Starter | $75 per filing or registration | Registering, filing, and staying compliant in the US, paying only for the actions you use |
Premium | Custom, with volume discounts | Multi-entity, multi-country, and high-volume businesses that want flat-rate pricing |
There are no onboarding fees, no transaction fees, and no long-term contract lock-in on any plan.
Free plan: monitor your exposure at no cost
The Free plan lets you see where you stand before you spend anything. It includes:
Global exposure (nexus) monitoring for both physical and economic nexus
Exposure and historical liability auditing
Automated risk assessment and nexus threshold alerts the moment you cross a threshold
AI-powered product categorization
Address validation and enrichment
Kin, your in-app AI sales tax assistant, grounded in your own data
CSV transaction imports
No-code integrations such as Shopify, Stripe, Chargebee, and BigCommerce
Starter plan: pay per action (filing, registration, etc.)
Starter includes everything in Free, plus the compliance work itself. Each filing or registration is $75, and you are only billed for the actions you actually use. Starter adds:
Automated registrations, filings, and remittance for US sales tax
Auto-file, auto-register, and deregistration where supported
Refunds and amendments
Basic exemption certificate management
Virtual mailbox for state notices
Faster data sync across your connected platforms
Onboarding assistance
24/7 live chat support with same-day human responses
Premium plan: custom pricing for more complex operations
Premium plans are custom, built around your business volume and needs, with flat-rate pricing and volume-based discounts. Our team sets it up with you directly. Premium includes everything in Starter, plus:
Multi-country compliance across the US, Canada, EU, UK, and 100+ countries
Real-time tax calculation on invoices through premium connectors such as QuickBooks, NetSuite, and Microsoft Dynamics 365
Back filing with Voluntary Disclosure Agreement (VDA) options
Advanced exemption certificate management, including bulk upload, secure certificate requests, and expiration notifications
Ready-made reports and custom analytics
API, SDK, and SSO access
Dedicated onboarding and account teams with SLA-backed premium support
💡 IMPORTANT TIP: If you have met nexus in more than 10 states, Premium is usually the better fit. Flat-rate pricing with volume discounts tends to cost less than per-action billing at that scale, and you gain the automation built for multi-state filing.
Premium pricing
Premium is custom pricing, scoped to your business and set when your contract is signed. This single contract covers everything included in Premium, such as API access, multi-country compliance, and volume-based filing, as one plan rather than separate line items.

How billing works on each plan
Plan | How you are billed | When you are billed |
|---|---|---|
Free | Not billed. No credit card is required. | Never |
Starter | Per action. Each filing or registration counts as one billable event. | After the billing period ends. Actions completed this period appear on your next invoice. |
Premium | A flat monthly subscription based on your custom plan. | In advance, at the start of each billing cycle. |
Why your Starter invoice can show $0.00: Filings, registrations, and other billable actions are charged after the period they were completed in. If your latest invoice shows $0.00, the actions you recently completed are simply queued for the upcoming billing cycle rather than the current one.
Any plan or pricing change is reflected automatically in your subscription. You can confirm your current plan and charges anytime under Configuration > Billing Details. Note that billing information is visible to Admins and Owners only; see Understanding User Roles in Kintsugi.
How You Can Pay
Kintsugi accepts credit and debit cards for subscription payments on Starter and Premium. The Free plan does not require any payment method.
ACH bank transfer is also available for customers paying from a U.S. bank account. To set up or switch to ACH, contact Support and we will send you a secure link to enter your banking details.
These payment details are used for your Kintsugi subscription only. They are separate from the bank details used to remit sales tax to state authorities, which you enter under Configuration > Bank Details. For more on that, see Setting Up Sales Tax Payment for Filings and Registration.
Ready to Upgrade?
Free to Starter: Self-serve. Go to Configuration > Billing Details, select Upgrade on the Current Subscription Plan card, and complete checkout inside the app. The change takes effect immediately.
Moving to Premium: Select Talk to Sales on the Premium card in the same window, or use the Talk to sales option on the pricing page. Our team follows up to build a plan around your volume and the countries you sell into.
