Workflow

중소기업 급여·4대보험 자동정산 API

Problem

2021년부터 급여명세서 교부가 의무화되었지만, 50인 미만 사업장은 급여 ERP가 없어 엑셀로 명세서를 만들고 카톡/이메일로 개별 발송한다. 미교부 시 과태료(30만원/건)가 부과되며, 매월 반복되는 2~4시간의 단순 반복 작업이다.

Solution

엑셀/CSV 급여 데이터를 업로드하면 법정 양식에 맞는 급여명세서를 자동 생성하고, 카카오톡 알림톡 또는 이메일로 일괄 발송. 직원별 열람 확인 로그와 과태료 방지용 교부 증빙을 자동 보관한다.

Target: 5~50인 규모 사업장 대표/경리 담당자 + 세무사 사무소

Revenue Model: 직원 수 기반 월 구독 — 10인까지 무료, 50인까지 월 1.5만원
