During the official price announcement season (March-June), tax accountants and CPAs must manually check and contact existing clients about changes in their property taxes. For 100 clients, it takes over 15 hours per week per accountant to look up official prices, analyze changes, and provide individual notifications. During this period, new consultation inquiries also surge, but due to insufficient staff, leads are missed.
Solution
When a tax accountant registers their client's real estate portfolio, the system automatically detects changes in official prices, generates a summary report of property tax changes for each client, and automatically sends it via KakaoTalk notification. It sends as a white-label under the tax accountant's brand to maintain client trust.
Target: Individual tax accountants, tax firms with 5 or fewer employees, and real estate tax consultants
Revenue Model: SaaS monthly 49,000 KRW (approx. $36.75) per account (up to 200 clients), additional 10,000 KRW (approx. $7.50) per month per 100 clients. Notification sending cost 15 KRW (approx. $0.01) per message, separate.
