About this app

SOLO: The Tax Friend for Solo Business Owners, Small Business Owners, and Freelancers

Just record your transactions, and we'll take care of everything from VAT and Withholding Tax to Comprehensive Income Tax.

Issuing Quotes and Connecting with Tax Accountants All in One Place

When working alone, the same worries return every month. How much did I earn this month? How much is the tax? Do I have to rewrite the quote from scratch? When was the VAT filing date?

SOLO is an app that takes care of those worries for you.

When you record transactions, your profit and loss for the month are automatically calculated. For quotes, simply enter client information, and VAT and 3.3% withholding tax are calculated automatically. You can save them as PDFs or send them directly via email.

A single photo of a receipt is enough to automatically register it as a transaction, and we send you notifications if outstanding receivables become too long.

If you import a Hometax CSV file, a month's worth of data is organized into your ledger all at once, and at the end of the month, you can receive a monthly report PDF with AI commentary.

When you are confused about taxes, just ask the AI. "How much will my comprehensive income tax be this year?" We calculate it for you instantly based on current data.

Whenever you need a tax accountant, you are immediately connected to a partner accountant. You don't have to shoulder the burden alone.

Our goal was not to cram in a lot of complex features, but to lighten your tax-related worries one by one.

Sincerely, SOLO, working steadfastly by your side.
SOLO, the tax friend for sole proprietors, small business owners, and freelancers. We take care of everything from VAT and withholding tax to comprehensive income tax. Get quotes issued and connect you with a tax accountant all in one place.
