Easy to use!
Kintsugi and the team there have been great to work with for the past year, from our launch. They are constantly updating the app, and the team is extremely responsive to any inquiry, bug/issue, etc. The app does excellent for managing sales tax operations and the team fills in any cracks for local regulatory shifts, bumps around registration and more. The billing is simple, straightforward and scalable. They have made the sales tax registration, tracking and filing a breeze.
Whenever you need them they are there! Very helpful team
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, especially small businesses juggling multiple tasks that need sales tax management. Kintsugi has been a great solution for us!
Excellent service, working with the Kintsugi has been great! Top notch customer service, fast and very reliable. Bravo!
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 knowledgeable support has made our sales tax process efficient and reliable, providing significant peace of mind.
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
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.
