Vertex

Vertex is an enterprise tax technology platform that automates indirect tax calculation, compliance, and reporting across multiple jurisdictions. It handles sales tax, use tax, VAT, and other transaction taxes for businesses with complex multi-state or international operations.

Accounting firms working with mid-market and large corporate clients use Vertex to manage indirect tax obligations that are too complex for manual tracking. The platform integrates with major ERP systems (SAP, Oracle, Microsoft Dynamics) and e-commerce platforms, calculating tax at the point of sale based on current rates and rules for each jurisdiction. It also handles returns filing, exemption certificate management, and audit support.

Vertex is best suited for firms advising enterprise clients with high transaction volumes and obligations across many jurisdictions. Smaller businesses with operations in a handful of states typically use lighter alternatives like Avalara or their accounting software’s built-in tax features.
