중소기업 급여·4대보험 자동정산 API

Problem

Since 2021, issuing pay slips has been mandatory, but workplaces with fewer than 50 employees lack payroll ERP, so they create statements in Excel and send them individually via KakaoTalk or email. Non-issuance incurs a fine of 300,000 KRW (approx. $225) per case, and this is a simple repetitive task taking 2–4 hours each month.

Solution

Upload Excel/CSV payroll data to automatically generate pay slips in the legally required format, and send them in bulk via KakaoTalk AlimTalk or email. Automatically store per-employee read confirmation logs and issuance proof to prevent fines.

Target: Representatives/accounting staff of businesses with 5–50 employees + tax accounting offices

Revenue Model: Monthly subscription based on employee count — free up to 10 employees, 15,000 KRW/month (approx. $11.25) up to 50 employees
