Vertex Tax Determination

Global tax determination software or "tax engine" automates the calculation of indirect taxes—such as sales & use tax, VAT, and GST—based on a combination of transaction details including location, product type, customer status, exemptions, and more. A single tax engine can be integrated directly to multiple transaction systems -- like ERP, e-commerce, and procurement systems -- to deliver consistent and precise tax calculations in real time. The tax engine provider continually updates the tax rules, calc formulas & rates eliminating the burden of updating tax tables and customizing source systems. A tax engine helps ensure tax accuracy and consistency, and supports global compliance requirements. Learn more about the Vertex O Series tax engine.

Tax automation systems apply localized tax rules in real time by referencing transaction details against continuously updated tax content for each country. This allows businesses to manage a wide variety of products, different sourcing rules and tax rates, thresholds, and exemptions automatically, regardless of the supply chain model or where the transaction takes place.

Real-time tax calculation engines can achieve high accuracy—often 99% or higher—when integrated properly and supported by up-to-date tax content and sourcing logic. They automate sales and procurement processes, reduce manual errors, and help ensure ERP, e-commerce and procurement systems tax accurately by instantly applying the latest tax rates at the time of the transaction.
