About this app

This is a smartphone-based income and expense management app that handles everything from side hustle income and expenses to bookkeeping for sole proprietors. Simply enter your daily sales and expenses into the calendar, and it will automatically aggregate them by account category, preparing you for tax filing. It can also be used as a freelancer's household budget or as a substitute for a cash book.

■ Features

・Input is as easy as tapping the calendar
You can record simply by selecting the amount and category. No bookkeeping knowledge is required.

・No more re-categorizing at the start of the year
Since expenses are categorized by account category from the moment you enter them, there's no need to reorganize a year's worth of receipts later.

・Even home office rent can be treated as a business expense
Once you decide on the percentage of rent allocated to business use, only that portion will be counted as a business expense each time.

■ Main Features

• Calendar-based income and expense entry (income, expenses, memos)
• Free addition and rearrangement of categories
• Account mapping (consumable supplies, communication expenses, rent, etc.)
• Setting household expense allocation (home rent, mobile phone bill, etc.)
• Annual sales, expenses, and profit summaries
• Expense list by account
• Monthly sales graph
• Export to CSV for tax accountants
• e-Tax transfer view (displayed in the same order as tax returns)
• Income and expense report for a specified period
• CSV output for lists and summaries
• Changing the start date of the month (supports payday start dates, etc.)
• Display of carried-over balance

■ Recommended for:

* Those who want to record a year's worth of income and expenses for tax filing purposes.
* Those who want to keep records using only their smartphone without owning a computer.
* Those who recreate tax documents for their tax accountant from scratch every year.
* Those who only want to record income and expenses for white-form tax filing.
* Those who want to manage income and expenses from a side business separately from their main business.
* Those who use their home as a business and want to allocate rent and communication costs.

■ What this app does not do:

This app does not create tax return forms or calculate tax amounts. It does not link to bank accounts or automatically read receipts. All you need to prepare are the figures for one year to provide to your tax accountant or e-Tax.

Functionality is kept to a minimum.

■ Price:

Free to use. Advertisements are displayed.

Features such as CSV export for tax accountants, e-Tax transfer view, reports specifying a period, CSV output for lists and summaries, and ad removal are available with a paid plan (¥600/month / ¥4,800/year).

Daily input, category settings, account mapping, household expense allocation settings, and annual sales, expenses, and profit viewing are available for free.

■ Please Note

This app is for summarizing income and expenses and does not provide tax-related judgments. For information on whether filing is required, which account categories apply, etc., please consult the National Tax Agency website, your local tax office, or a tax accountant.

Please feel free to submit any questions or requests through the "Bug Report/Request" section within the app.
