What our customers say
David Hewlett
CEO, SmartLabels
“I was looking for a solution after I hit the limits that now require me to start collecting sales tax. I'd never done it before, so I had to start researching. I looked at other software solutions, and then came across Kintsugi and found them to be the only one that would truly take care of everything from start to finish.”
Adam Klausner
President and COO, Symbiome
“With our previous provider, I was tracking nexus myself and spending time on tasks like being on hold with the Secretary of State’s office, and my accountant and bookkeeper had to stay actively involved, but Kintsugi completely solved this problem by taking over these time-consuming tasks.”
