THE PROBLEM
Sales tax inside Rillet shouldn't feel like a second ERP.
Most tax engines bolt onto Rillet with layers of add-on modules, opaque pricing, and ticket-queue support that slows everything down. Finance and tax teams end up spending more time managing the tax software than managing tax.
Clarus takes a different approach. One focused calculation engine, a clean connection into Rillet, and US-based tax professionals on the other end of the phone.
✓
One calculation engine built across your environment
✓
Integration built and maintained by Clarus
✓
Predictable pricing with no add-on modules at renewal
✓
Direct access to real US-based tax professionals
How the Integration Works
Built by our team, configured to your operation.
AkuCalc connects to Rillet through an integration that Clarus built and maintains. That matters: when something needs to change, you're talking to the team who wrote the code, not a third-party connector vendor.

Built for growing businesses, not enterprise complexity.
Many enterprise tax platforms were built around layers of modules and add-ons. We built Clarus to address the gaps those tools often create inside ERPs like Rillet, simplifying calculation, certificates, and licensing inside real operational workflows.
For Rillet customers, that means a faster implementation, predictable pricing, and a support model built around direct access to real tax professionals.
