The record

Purpose: Systax provides tax technology and expertise to help companies manage taxation, reduce risk, and improve tax processes.
Tax rules: The company says its updated database covers more than 31 million tax rules across economic sectors and all 27 Brazilian states.
Tax data service: Its Content as a Service offering provides personalized tax parameters and daily updates for a customer’s software and operations.
Tax coverage: The CaaS page lists ICMS, ICMS/ST, ICMS advance payment, IPI, PIS/Cofins, and cBenef among the taxes and rules it covers.
Integrations: CaaS is available for integration with SAP ECC, Protheus (TOTVS), and other ERPs, using web services where needed.
Calculation engine: The Vertex O Series page says the engine integrates natively with SAP ECC and S/4HANA and calculates taxes in real time for transactions.
Tax reform: The O Series page says the engine supports CBS, IBS, and the Selective Tax associated with Brazil’s tax reform.
Integration methods: Documented connection options include SOAP/XML web services, Cockpit in the cloud or locally, file import and export, and a calculation engine API or DLL.
Security detail: The integration documentation says customers need not allow connections to their own database; the Systax Cockpit database contains only that customer’s rules.
Operational limits: The Systax Light page says product classification review may require an additional contract, and grouping products to reduce rule volume and monthly cost must be arranged commercially.
Support: The support page directs technical support requests by email and asks customers to include their contact details, company name, and a problem description.
Intended customers: The company describes its solutions for businesses and lists technology companies, ERP providers, implementation consultancies, and tax or audit consultancies among its partners.
