Unlock accuracy and efficiency with Vertex TaxCalc, global tax determination software

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 customising 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 localised 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.

Yes, leading tax engines integrate seamlessly with major ERP platforms like SAP, Oracle, NetSuite, Microsoft Dynamics, Workday as well as e-commerce and procurement platforms, and other transaction systems. These integrations enable automated tax calculation directly within order to cash (customer) and procure to pay (supplier) workflows. A single tax engine can integrate to multiple source systems to centralise and standardise tax determination globally creating consistency across channels.
