Problem

Among small business owners in Korea (approximately 7 million businesses), those considering transitioning to unattended stores or kiosks must compare fees, features, and compatibility of over 30 vendors when selecting payment terminals (POS, kiosk, QR). A wrong choice can result in unnecessary fees of 100,000-300,000 KRW per month (approx. $75-$225) or customer attrition. Designing the optimal cash/card/simple payment ratio requires an average of over 20 hours of research.

Solution

Users input their store type (cafe, convenience store, unattended store, etc.) and monthly sales volume, and the system recommends the optimal payment infrastructure combination (POS + kiosk + QR + cash ratio). It automatically generates a comparison table of fees and features for over 30 payment vendors, a simulation of expected savings from unattended conversion, and an installation checklist.

Target: Small business owners with monthly sales of 5 million to 50 million KRW (approx. $3,750 to $37,500) (cafes, restaurants, unattended stores), aged 30-50.
Revenue Model: Basic diagnosis free, detailed report 39,000 KRW per transaction (approx. $29.25), monthly subscription 19,000 KRW (approx. $14.25) (fee change monitoring + alerts).
