Solo Biz Regulatory Change Alert

Derivation Chain

Step 1 Solo Entrepreneur Tax Accounting & Labor automation
→
Step 2 Existing Tax Accounting SaaS lacks mid-senior context
→
Step 3 No channel to receive advance alerts on how Regulation changes impact 'my business'

Problem

A 58-year-old Solo Entrepreneur running a consulting practice after retirement must manually track annual changes to VAT simplified taxation thresholds, income tax deduction items, social insurance coverage rules, and employment subsidy eligibility. Announcements are scattered across the National Tax Service, Ministry of Employment, and National Health Insurance Service, with no contextual filtering for 'does this change apply to my revenue size and industry?' — leading to repeated missed deadlines, penalty taxes, and lost subsidies.

Solution

Users register their business type, revenue range, and years in operation on the web. When relevant Tax Accounting, Labor, or subsidy Regulation changes occur, the system filters for 'only what applies to my business' and sends alerts. Each change is summarized in three lines: what changed, what action is needed, and the deadline.

Target: Ages 55–63, post-retirement Solo Entrepreneurs (consultants, Freelancers, small shop owners) who use a Tax Accounting firm for bookkeeping but receive no proactive Regulation change alerts
Revenue Model: 3 alerts/month free. Premium (unlimited alerts + filing deadline calendar + subsidy matching) 9,900 KRW/month (~$7.50/month).
Ecosystem Role: Regulation
MVP Estimate: 2_weeks
