Market

전자세금계산서 API 연동 미들웨어

Workflow

세무사무소→고객사 간 매월 자료요청·수집·독촉 수작업 병목

Problem

세무사무소 직원이 매월 50~200개 고객사에 증빙자료를 개별 요청·독촉하며 평균 업무시간의 30%를 소비. 전자세금계산서 의무화 확대로 처리 건수는 늘지만 자료수집은 여전히 카톡·이메일 수작업.

Solution

고객사별 자동 자료요청 링크 발송 → 업로드 포털 → 미제출 자동 리마인더 → 수집 완료 시 회계SW 연동 전송. 입력: 고객사 목록·요청 항목 템플릿, 산출물: 수집 현황 대시보드·회계SW 자동 연동.

Target: 직원 3~15명 규모 세무사무소 + 기장 담당 실무자

Revenue Model: 사무소당 월 5만원 구독 (고객사 100개까지), 추가 고객사 건당 300원
