Decision-to-Defense Hero

More than 60% of the Fortune 500 trust Vertex to comply continuously and grow with confidence.

Why now?

Global compliance is moving into the transaction itself.

As mandates push continuous controls directly into every invoice, enterprises face two compounding pressures — one at the decision, one in the operation — that together widen the Compliance Confidence GapTM.

Defensibility DriftTM

The widening gap between the decisions a business makes at the point of transaction and its ability to prove those outcomes to authorities across an accelerating patchwork of jurisdictions.

Compliance Operations (CompOps) DragTM

The manual rework, integration friction, and delayed audit response created by fragmented tax, ERP, e-commerce, and reporting systems that were never designed to run continuous compliance in real time — the compounding cost of doing Compliance Operations without a coordinating discipline.

Left ungoverned, they compound into a vicious cycle of complexity.

34% hit 3 or more high-impact tax software errors a year. 46% of audit issues stem from a mix of factors, not one cause. 80% reach audit readiness only through significant manual effort.

The Compliance Confidence GapTM

The widening cost that compounds when drift and drag go ungoverned — the growing distance between the revenue enterprises could book with defensible confidence and the revenue they conservatively report because they cannot prove every determination. Closed by governing the lifecycle end-to-end from determination to defense.

1 in 3 enterprises leave $1M+ on the table every year, by their own estimate.

Decision-to-Defense Lifecycle of four operational pillars, with the system of control at the center. 1) Determine - Accurate tax calculation at the moment of transaction, in real time. 2) Prove - Evidence through an audit-defensible source of tax truth. 3) Defend - Readiness for audit, notice, appeal, and litigation. 4) Improve - What Defense teaches feeds forward into better determination.

Governed end-to-end, the same lifecycle compounds the other way: a virtuous cycle of control that closes the Compliance Confidence Gap.
