Hands-on, communicative, and genuinely on top of US sales tax.
I moved to Kintsugi after a frustrating experience with another sales tax provider that went unresponsive right when I needed support. From the very first call, Kintsugi really impressed me — and months in, they've been exceptional: very hands-on, with lots of communication, which is exactly what you want when you're dealing with something as complex as US sales tax (different rules and filing periods in every state).
I run a small international e-commerce brand, so having a team that actually responds and keeps me across my registrations and filings has taken a huge weight off. Happy to recommend them to other store owners.
I would give 10 stars if I could. This is the true end to end sales tax solution you are looking for. They take care of everything and you just get to focus on other parts of your business. Their customer service is great too. 100% recommend.
I’ve had a great experience using Kintsugi for Shopify. The setup was incredibly seamless and much faster than I expected, with clear guidance throughout the process. What really stands out is their support since it is easy to get in touch with someone quickly and the team is knowledgeable and actually helpful when you have questions. On top of that, the pricing feels very fair compared to many other options, especially considering the quality of the product and support you get. Overall, it has been a reliable and straightforward solution that does exactly what it is supposed to do.
