Responsiveness and reliability! Most accountants don’t answer your questions for weeks, and try to avoid being helpful to save time. Rivet felt like the opposite. They went above and beyond.

Pratyush Buddiga
Partner at Susa Ventures
Rivet is far and away the best firm I've ever worked with. Their staff is amazing, and their responsiveness cannot be matched. I've recommended many people to Rivet already, and each has said the same thing: "This group is the best."
Kurtis Hanni
CFO at Bison CFO
Most tax firms I came across were hyper disconnected from their clients. It felt like I was just another number to them. Rivet's been seamless. Especially with their updated dashboard - now, I can just go in and drop in the docs I have, and I'm all set.
