A Google Sheets / Excel cashflow system for freelancers with lumpy client payments. Tracks income and expenses, calculates tax set-aside and runway, and maps categories to Schedule C, friendly lines. Digital download only: Markdown guides + CSV starter data. Buy via PayPal ($19 at paypal.me/mohamedelsheikh915/19USD). Delivery is manual, you receive the ZIP by email after PayPal receipt, typically within 15 minutes. No SaaS login, no subscription.
I kept seeing freelancers panic about taxes and runway because bank balances lie when income is irregular. Built a simple offline spreadsheet workflow instead of another app.
