Why Clarus Tax Technologies
Sales tax compliance software, the way it should have been built.
Focused, not bloated
Three products that do their jobs. No modules you'll never use, no features you're paying for twice.
Predictable pricing
Transparent, scalable pricing that grows with your business. No surprise add-on fees at renewal.
Real support, not a ticket queue
US-based tax experts you can actually reach. You'll get answers, not deflections. One point of contact from implementation through go-live and beyond.
Built by people who've used the other tools
Our founders implemented the major tax platforms from the buyer's side and saw exactly where they fall short. We built Clarus to fix what those tools got wrong.
Proof
Trusted by teams managing real sales tax complexity.
AkuCert has been a much better experience. It's backed by Clarus' excellent customer support, customizable for our business, and about 30% less expensive than other solutions. We're no longer hit with hidden add-on fees — it's been a smart choice for our team.
The software has been incredibly helpful in quickly identifying companies that claimed to be tax-exempt but were not. Not having to worry about that risk is very comforting.
