I like the Slack support that proved more effective than email due to its faster response time.

We switched from Avalara AvaTax to Kintsugi to handle sales tax calculation, collection, and remittance across our BigCommerce store and QuickBooks Online. What I like best is that it now just runs in the background. Tax gets calculated correctly at checkout, flows into QBO, and filings get handled without me babysitting it. We had some bumps early in the transition, but the Kintsugi team took ownership. They dug into our setup, coded fixes on their end, and followed through until everything worked. I joked with them that the less I talk to them, the better, and that’s where we are now. For a small business owner, that’s the best compliment I can give a tax tool. It frees me to focus on selling instead of tracking state tax rules.

The interface is simple and the platform really helped streamline our transaction reporting.
