# Software License Audit

> **Definition:** A Software License Audit is a compliance review where a software vendor (SAP, Oracle, Salesforce) audits a customer's actual system usage against their contracted license terms — often resulting in six-figure true-up invoices for unlicensed usage.

## In depth

SAP, Oracle, and Salesforce reserve the right to audit customers annually for license compliance. Common triggers include: adding users beyond contracted seats, using features in unlicensed modules, or connecting systems via indirect access. Audit findings regularly result in true-up invoices of $500K–$10M for enterprise customers. Switching to custom ERP permanently eliminates license audit risk since you own the source code and have no vendor licensing obligations.

## How ERPStack applies this

We help clients build License Audit Risk Assessments during the discovery phase, quantifying their current license exposure vs. the cost of a custom replacement — typically showing 3-year savings of $2M+ for mid-market companies.
