Solopreneur Finance OS — freelance & side-hustle money tracker (Excel + Google Sheets)

Stop guessing what your side hustle actually earns.

Solopreneur Finance OS is a single spreadsheet system built for freelancers, solo operators, and side-hustlers who want their numbers in one place without paying for accounting software.

WHAT'S INSIDE

Dashboard — income vs expenses by month (with chart), YTD profit, open and overdue invoices, and a full expense-category breakdown. All automatic.

Transactions — log every dollar with Type/Category dropdowns (Schedule C-aligned categories) and room for ~500 entries per year.

Invoice log — Draft/Sent/Paid status with automatic days-overdue counting.

Mileage log — deductible value computed from your editable IRS-rate setting.

Quarterly tax estimator — a suggested set-aside per quarter from your own effective-rate estimate, so tax season never ambushes you.

Settings & guide — your rates, the category list, and a plain-English quick guide.
