Problem

A 56-year-old retiree running an online store manages sales on Naver Smartstore, tax filings on HomeTax, inventory in Excel, and customer inquiries on KakaoTalk — four separate platforms consuming 2 hours daily. During VAT filing season, they spend 3 days manually compiling sales and purchase records. Existing ERP Solutions cost 100,000–300,000 won (~$75–$225/month) and are feature-bloated for solo sellers.

Solution

A web dashboard showing Smartstore sales summary, estimated VAT for the current month, inventory status, and recent customer inquiries on a single screen. Upload Smartstore Excel export files for automatic parsing, automated VAT estimation, and pre-filing-season checklist alerts.

Target: Solo online sellers aged 50–60 (post-retirement, on Smartstore or Coupang), monthly revenue 1,000,000–20,000,000 won (~$750–$15,000), operating without employees

Revenue Model: Free for monthly revenue under 5,000,000 won (~$3,750); 9,900 won (~$7.50/month) above that; quarterly VAT auto-calculation Report at 4,900 won (~$3.70)
