Frequently Asked Questions

• Does Kintsugi calculate sales tax inside Stripe?

  Yes. Kintsugi's tax engine calculates sales tax on your Stripe invoices and subscription charges in real time, as they're created, and uses that same data to monitor your total tax obligations and file your returns. Your billing and your filings stay aligned.

• Does Kintsugi support Stripe Payments, including Checkout and Payment Links?

  Yes. Kintsugi syncs your charges and refunds from Stripe Payments alongside your invoices and subscriptions from Stripe Billing, so your nexus tracking and tax exposure reflect all of your Stripe revenue. For real-time tax calculation on a transaction that isn't tied to an invoice, such as a Stripe Checkout session or a Payment Link, our team will walk you through the setup for your account.

• How does Kintsugi sync data from Stripe?

  Kintsugi automatically pulls your customers, products, subscriptions, invoices, charges, and refunds from Stripe to calculate your sales tax, VAT, and GST obligations. Your data stays in sync, no manual exports or duplicate entry required.

• How long does it take to set up the Stripe integration?

  Most customers are connected and running in under 30 minutes. Once you authorize the integration, Kintsugi begins analyzing your data immediately to surface nexus exposure and filing obligations.

• I'm switching from Avalara (or Stripe Tax). Can I use Kintsugi with my existing Stripe setup?

  Yes. It's one of the most common reasons customers come to us. Kintsugi connects directly to Stripe without requiring you to change how you bill. You can run both in parallel during evaluation, and our team will help you transition on your timeline.

• Can Kintsugi handle sales tax if I bill across multiple states, or internationally?

  Yes. Kintsugi monitors threshold exposure across all US states and 100+ countries, using your Stripe data as the source of truth. Whether you're navigating economic nexus in a new state or managing VAT obligations in the EU, Kintsugi tracks it automatically.

• What happens when I issue a refund in Stripe?

  Kintsugi syncs refunds from Stripe so your tax liability calculations stay accurate. We account for these adjustments at the transaction level, so your filings reflect what you actually collected, not just gross billings.

• Is my Stripe data secure with Kintsugi?

  Yes. Kintsugi is SOC 2, Type II certified and uses a least-privilege approach to API access when connecting with your Stripe data. All data is encrypted in transit and at rest. Our security posture is designed for the same finance and compliance teams that scrutinize every vendor in their stack, and we're happy to share our security documentation upon request.
