THE PRODUCT LINEUP
Three products. Purpose-built. Not overloaded.
Manage accurate sales tax calculation, exemption certificates, and business licenses with clarity and control.
Built by tax experts, so your team can manage compliance with confidence.
Real-time, rooftop-accurate calculation across 13,000+ US tax jurisdictions. Rates and rules update automatically, so every transaction is calculated correctly without manual checks.
We own product taxability mapping — so your team isn’t guessing at tax treatment, and you’re not carrying the liability. Connects to your ERP, billing, and ecommerce systems.
Collect, validate, and renew exemption certificates in one place. Automated expiration alerts and a customer upload portal keep documentation current.
Audit-ready records, so you’re never exposed when an audit arrives.
Track license requirements, deadlines, and renewals across every location and jurisdiction. Early alerts and centralized records.
One dashboard. Zero missed renewals.
Works together: When AkuCert has a valid certificate on file, AkuCalc applies the exemption automatically. No double entry, no missed exemptions.
SWITCHING?
Switching from another platform? It’s an upgrade, not just a move.
We migrate your data end-to-end and fix what your current system got wrong. Most teams don’t realize how much is broken until we surface it. Typical implementation takes about 60 days — and you end up in a better position than where you started.
WHY CLARUS
Sales tax compliance software, the way it should have been built.
Most sales tax platforms were built to sell you everything. Ours was built to do three things exceptionally well — not everything poorly.
01
Focused, not bloated
Three products that do their jobs. No modules you’ll never use, no features you’re paying for twice.
02
Predictable pricing
Transparent, scalable pricing that grows with your business. No surprise add-on fees at renewal.
03
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.
04
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."
Diana Jander — Indirect Tax Director, Cardinal Health
“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.”
