We love Rivet!
It’s been awesome seeing Rivet serve many of the fastest growing companies in the world.
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."
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.
I wanted a tax firm that could handle things quickly, accurately, and with zero hassle, and Rivet delivered on all fronts. Their speed and responsiveness set them apart—no one comes close.
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.
I wish we had used Rivet from day one. Was impressive to see their degree of competence in knowing what they knew, what they didn't, learning quickly, and guiding us through our work in our final stages.
Outstanding customer service, really strong expertise, and the best responsiveness I’ve seen. Nick, Kyle and the Rivet team have been amazing to work with for my personal prep.
