FAQs
How does the WooCommerce plugin installation work?
Generate REST API keys in WooCommerce (Settings → Advanced → REST API). Install Kintsugi plugin. Enter your keys. That's it. Total time: about 3 minutes.
Does this replace WooCommerce's built-in tax features?
Yes and no. Kintsugi handles the actual calculation, filing, and remittance. WooCommerce still displays tax at checkout, but now with accurate, real-time rates from Kintsugi.
What about variable products and bundles?
Fully supported. Our AI classifies complex products, bundles, and variations correctly for tax purposes. Different taxability rules by state all handled automatically.
Can I still offer tax-exempt sales?
Yes. Store exemption certificates in Kintsugi. Mark customers as exempt. Tax automatically removed from qualifying orders while maintaining audit documentation.
What if I already have tax issues from before?
We help resolve past exposure through VDAs (Voluntary Disclosure Agreements) and back-filing. Clean slate going forward with automated compliance.
Do you support WooCommerce Subscriptions?
Yes. Recurring billing, subscription boxes, and membership sites all supported. Proper tax handling for both initial and recurring charges.
How is this different from TaxJar for WooCommerce?
TaxJar's WooCommerce integration is poorly maintained with numerous reported issues. Kintsugi offers active development, complete automation (not just calculations), and responsive support.
