CereTax vs Numeral

CereTax automates sales tax calculation, validation, and compliance for businesses handling complex transactions across jurisdictions. Its language-agnostic API provides real-time calculations for sales, purchases, and telecom transactions, while the web platform supports related workflows. The process validates addresses and line-item taxability, applies rates and sourcing rules, produces invoice-ready output, aggregates transactions, and synchronizes results with billing or ERP systems. CereTax describes rooftop-level mapping and jurisdiction-specific calculations covering 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, QuickBooks Online, Salesforce, BigCommerce, Stripe, and Rillet. The company says its API handles millions of calls without latency degradation. Security descriptions include encryption in transit and at rest and access controls. Most implementations take 3–6 months. Pricing is by custom quote and may depend on requests, transactions, or seats.

Numeral provides sales tax, VAT, and GST services through an API. Listed capabilities include sales-tax calculation, tax registration, and automated return filing. Its free Monitoring plan has no listed price and includes a nexus study, physical and economic nexus monitoring, threshold alerts, and exposure and historical-liability audits. Professional costs $75 a month; standard accounts run month-to-month and are billed as filings occur. That plan covers registrations, filings, remittance, autofile and autoregister, virtual-mailbox monitoring for tax mail, AI product classification, and exemption-certificate management. Professional registration costs $150 a month as a one-time registration fee per state and covers state registrations and support. Enterprise has no listed price and adds global coverage, a tax engine, API access, tax-lawyer consultations, and advanced reporting and analytics. Numeral was founded in 2022. The listed platform is API, so the available interface is intended for software integration rather than a separately described web application.
