Step 4 AI budget optimization reports based on settlement data

Problem

The finance team of a mid-sized company (50-300 employees) that has adopted AI APIs spends 8-16 hours per month manually extracting usage from each vendor dashboard and allocating costs to departments/projects in Excel to settle monthly AI API costs of 5-30 million KRW (~$3,750-22,500). Unclear allocation criteria lead to quarterly cost disputes between departments, and missed cost optimization opportunities result in 15-30% overspending per month.

Solution

By integrating multi-vendor API keys (OpenAI, Anthropic, Chinese AI, etc.), it automatically tags token usage by department, project, and individual, and generates monthly settlement reports. Based on usage pattern analysis, it recommends cost-saving opportunities such as model downgrades, caching, and batch processing, and sends real-time alerts when budgets are exceeded.

Target: Finance and DevOps teams at mid-sized IT companies with monthly AI API costs of 5 million KRW (~$3,750) or more, team size 3-15 people
Revenue Model: SaaS: 99,000 KRW/month (~$74.25) for monthly API costs up to 30 million KRW (~$22,500), 199,000 KRW/month (~$149.25) for costs exceeding that, plus optional 10% performance fee on API cost savings.
