Taking the Pain Out of Tax

The scale of indirect tax complexity

In the U.S. alone, there are more than 12,000 taxing jurisdictions, and they change their rates and rules all the time. For companies operating globally, that number grows to over 19,000. Keeping up manually isn't realistic. Errors create compliance gaps, audit exposure, and drag on finance and IT teams.

One engine, many source systems

A centralized tax engine connects to your ERP, e-commerce, and procurement systems through a single integration. Tax content updates automatically. Every transaction pulls from the same source of accurate, current tax rules. You get consistent calculations across sales, use, and VAT without maintaining separate tax logic in each system. IT teams spend less time on maintenance, and tax teams get better control over compliance and reporting.

How the Vertex tax engine works

When a transaction occurs, your source system sends the transaction data to the Vertex tax engine. Vertex applies address cleansing to confirm the correct taxing jurisdiction, then calculates the applicable indirect tax using embedded rules and rates. The tax amount is returned to the source application in real time to complete the transaction. As you add new source applications, they connect to the same engine, so your tax process scales as your business grows.

Automation across both sides of the business

On the accounts receivable side, a single tax engine handles calculations for all sales transactions, keeping commerce moving without friction. On the accounts payable side, automating sales, use, and VAT determination improves the accuracy of taxes paid and accrued. Rules-based logic replaces manual decisions by AP clerks at both the purchase order stage and the invoice reconciliation stage.

The outcome for your team

Integrating a tax engine reduces manual processes, improves audit performance, and frees up resources across tax, finance, and IT. It also creates more streamlined order-to-cash and procure-to-pay cycles. The result is a tax function that is more reliable, more scalable, and better prepared for the constant change that comes with operating across multiple jurisdictions.
