Household Budget / Sales & Expense Management App SaaS Platform (Stripe Billing, with Operator Admin Screen)
オンラインBusiness
Business description
This is a SaaS-type web household-budget app for companies and developers.
There are two tiers, general users and administrators. General users get basic features such as registering income/expenses, aggregating them, and displaying graphs, while administrators get features essential to running the service, such as user management, billing management, and audit logs. The app also uses Stripe API for subscriptions, with a mechanism for selecting and being billed for monthly or annual plans.
On the general-user screen, users can register income and expenses by entering the date, category, amount, and a memo. The registered data is automatically visualized as daily bar charts and category-based pie charts, and can also be exported as PDF or CSV. This makes it usable for a wide range of purposes, from personal use to in-company expense settlement and sales/expense management for small businesses.
On the administrator page, there are features for listing registered users, adding/deleting users, changing permissions, and proxy login, making it easy to perform operations needed as an administrator. All administrator actions are recorded in the database as audit logs, so the app can be used with confidence from a security and transparency standpoint. Through Stripe integration, the list of users with active subscriptions is synced, and unlinked users are clearly shown as "Not Linked," so billing status can be grasped at a glance. In addition, each user's invoice can be output as PDF or CSV, making accounting processing efficient.
The tech stack uses Flask (Python) on the backend, Bootstrap 5 / Jinja2 on the frontend, and SQLite3 for the database. PDF generation uses reportlab, which already supports Japanese, and one-click startup is possible using Docker / docker-compose. It also features environment-variable management via .env and a demo-data seeding feature via a seed script, making it useful for operation checks, customer-facing demos, and more.
What is included in the transfer covers the full source code, the DB schema, the environment configuration file (.env.example), the Docker configuration, and the seed script. If desired, the transfer can also include the hosting environment.
