Whenever you need them they are there! Very helpful team
— MedShop Direct
Kelcies LLC has been using Kintsugi for about 12 months, and it has proven to be an excellent choice. The integration with my Shopify stores was straightforward, and the service runs automatically, monitoring nexus requirements in each state and identifying how much sales tax to charge and when to pay it. The support has also been fantastic. I highly recommend this service to any company, especial...

— VKBSIM US
Working with Kintsugi has been fantastic! We previously tracked sales tax with Excel and filed manually, which was time-consuming and uncertain. Kintsugi automated our filings, improved compliance, and ensured accurate payments. They verified we had the correct license types in all states, integrated Shopify and Amazon stores, and supported manual ERP data imports. Their responsive and knowledgeab...

Awesome real time dashboard that shows where we have existing and upcoming thresholds. Also organizes all existing and historical filings in one place for convenient visibility for our accounting team. The service is what separates them. They've gone above and beyond anytime anything has come up. Would recommend 15 times out of 10. Thanks
— Vincero Collective
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.

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 some...

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 ot...

Hello, We have been working with Kintsugi for over an year now and there are really good things happened to us as a Ecommerce brand 1. Fully automated sales tax without any interruption while sales tax being one of the clumsy activity and no software in the market is closer to what kintsugi is doing. 2. Kintsugi customer & Engineer team truly a top notch and queries are resolved with top profes...

Running Laissez Faire Wear — an authentic Louisiana-themed apparel brand built for people who live the culture, not just visit it — means we wear a lot of hats. Design, marketing, customer service, and yes, the unglamorous side of running a business: taxes. If you've ever tried to navigate Louisiana's tax landscape, you know it's not for the faint of heart. We're talking separate filings for the...

Just switched over and super happy with the experience so far! Totally automated, great customer service, and huge cost savings vs our last provider!
— &Collar
As a lean brand owner, sales tax was always that nagging admin task I dreaded. Kintsugi changed everything. It handles nexus monitoring, calculations, filing, and remittance automatically I literally don't think about sales tax anymore. The time I've saved has been redirected to what actually grows the business: product development and customer acquisition. No more spreadsheets, no more complianc...

The Kintsugi team is on it! So happy we chose to use Kintsugi.
— Thuren Fabrication
Very good and easy setup. It is great to see when Nexus is due.
— Pridelity
Small farm and farm store and quarterly sales tax was such a challenge for me. Now that Kintsugi handles it for us, I have new challenges -- ground squirrels. Super support team; great product; out of my mind!
— Capay Valley Lavender
We moved away from Avalara because we needed some human contact. Kintsugi team was awesome to onboard us and get the Sales Tax filing done with just the right amount of support along the way (and no meaningless automated emails, like we were getting before). I highly recommend Kintsugi. The price is super reasonable too and they didn't lock us into a 1 year contract, just month to month. Great...
