### FAQs

What ecommerce platforms does Kintsugi support?

Shopify, Amazon, Etsy, eBay, Square, WooCommerce, BigCommerce, TikTok Shop, and more. Plus custom API support for proprietary platforms. Everything syncs automatically.

How does Kintsugi handle marketplace facilitator laws?

We automatically track which marketplaces collect tax on your behalf and which require you to collect. No double taxation, no gaps in coverage.

Can you handle high-volume sellers?

Absolutely. Fixed monthly rates based on filing frequency, not transaction volume. The more you sell, the lower your per-filing cost becomes.

What if we sell on platforms you don't integrate with?

Our API handles any platform. If you can export your sales data, we can automate your compliance. Custom integrations available for enterprise clients.

How does pricing work?

$75 per filing or registration. No per-transaction fees. Fixed-rate plans available for high-volume sellers. Free to connect and see your tax liability.

How do I collect sales tax for ecommerce?

Register in states where you have nexus → Configure tax collection at checkout → File returns quarterly → Remit payments on time. Kintsugi automates this entire process.

Which sales tax software should I use?

For multi-channel sellers: Kintsugi (full automation, no per-transaction fees). For Stripe-only: Stripe Tax. For basic calculations only: TaxJar. For enterprise: Avalara (expensive but comprehensive).

Can Shopify handle my sales tax?

Shopify calculates tax at checkout but doesn't file returns or track nexus. You'll need additional software for complete compliance.
