Case study
Alvaria provides enterprise contact center solutions, including voice over IP (VoIP) and related hardware. It used CereTax to generate and compile month-end reports in less time and with less hassle than its legacy provider.
Growth was outpacing Alvaria's tax tools. New SKUs, hybrid pricing, and shifting nexus rules were bogging down billing.
CereTax stepped in with fast integration into their existing systems, clean, accurate tax logic with no manual rework, and real-time visibility into how and where tax was applied.
Alvaria scaled faster with fewer errors, less busywork, and a lot more confidence. Tax stopped being a blocker.

Stay ahead of subscription tax rules, nexus changes, and SaaS billing compliance.
