Problem

When a 55-year-old Restaurant owner needs to transfer their business due to health issues, there's no standard for setting the goodwill price. Real estate agents inflate goodwill to increase their commission, or deflate it to push a quick sale. While the Commercial Lease Protection Act protects goodwill rights, it provides no formula for calculating 'fair goodwill.' Hiring a professional appraiser costs $750-$2,250 (~1,000,000-3,000,000 KRW). As a result, relying on gut feeling commonly leads to losses of $3,750-$15,000 (~5,000,000-20,000,000 KRW).

Solution

Users input business type, location (address), revenue, years in operation, and interior investment amount. The tool calculates a fair goodwill range based on actual transaction data from the same commercial district and business type. It breaks down the three components — business rights, facility rights, and location premium (license rights) — and also applies the National Tax Service's business goodwill valuation method for cross-reference.

Target: Ages 50-62, business owners planning to sell or acquire a small business (Restaurant, Cafe, salon, retail shop)
Revenue Model: Basic fair range estimate free; detailed valuation Report (with comparable cases) $15 Per Transaction (~19,900 KRW); including transfer contract template $22.50 (~29,900 KRW)
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
