Vertex is the enterprise standard for indirect tax — sales tax, VAT, GST, and consumer use tax — across thousands of jurisdictions. PeakCommerce calls Vertex inline at checkout to calculate tax accurately and posts committed transactions back for filing and audit.

What you can do

Real-time sales tax, VAT, and GST calculation in checkout
Address validation and jurisdiction assignment for compliance
Post committed transactions to Vertex for returns and audit
Manage exemption certificates against Vertex Exemption Certificate Manager
Support nexus tracking and rate updates without code changes

How it works

REST API

Vertex O Series / Vertex Cloud REST API called inline at checkout authorization. Authentication is configured once from the PeakCommerce console — no middleware or custom infrastructure required. Events flow bidirectionally in near real time, with retries and a full audit trail surfaced in the operations console.

Built on the same security foundation

Every integration runs on PeakCommerce's SOC 2 Type II–certified infrastructure with encrypted-at-rest credentials, scoped access tokens, audit logging, and granular permissioning. Tokens are stored in our hardened secrets vault and never exposed to customer-facing surfaces.
