A web-based bookkeeping app for Japanese blue‑tax filing
The project implements a full‑stack Next.js application that lets users manage journal entries, profit‑and‑loss statements, balance sheets, fixed assets, and deductions for Japanese blue‑tax filing. It includes features like CRUD operations, data validation, idempotent imports, and optional Notion invoice import. Designed for small businesses and accountants, it offers a self‑hosted alternative to commercial tax software. Its focused domain and ready‑to‑run setup make it a practical productivity tool.
