CereTax
What it is
CereTax is a sales tax platform for businesses handling complex transactions across jurisdictions. Its language-agnostic API provides real-time calculations for sales, purchases, and telecom transactions, while its web tools support calculation, validation, and compliance work. The process can validate addresses and line-item taxability, apply rates and sourcing rules, produce invoice-ready results, aggregate transactions, and synchronize outputs with billing or ERP systems. CereTax describes rooftop-level address mapping and jurisdiction-specific calculations that include special district taxes, telecom levies, and utility surcharges. Configurable rules, line-level reporting, and documentation trails support audit review. Listed integrations include NetSuite, Microsoft Dynamics 365 Business Central and Finance & Operations, QuickBooks Online, Salesforce, BigCommerce, Stripe, and Rillet. CereTax says its API can handle millions of calls without latency degradation. Security controls include encryption in transit and at rest and access controls. Most implementations take three to six months, according to CereTax. Pricing is usage-based and available on request.
