Spend Overview
Real-time analytics
Most Companies Lose Visibility and Control Over SaaS Spending.
IT managers, procurement teams, and finance leaders struggle to track software spending, manage licenses, and prevent shadow IT. The result: waste, compliance risk, and lost control of the SaaS stack.
Duplicate SaaS Tools
Multiple teams buy overlapping tools. Zero visibility into software governance.
Unused Software Licenses
Paying for seats nobody uses. Wasting 20-30% of software license budget.
Shadow IT & Visibility Gaps
Departments use unauthorized SaaS. Procurement loses control of the software stack.
Uncontrolled SaaS Spending
Software costs grow 2-3X faster than revenue. No spend management visibility.
