The Challenge
Most personal finance tools are built for salaried employees with predictable income. Freelancers face a completely different tax reality, self-employment tax, quarterly payments, and no employer withholding. The challenge was designing calculators that handle variable income correctly while remaining simple enough for non-accountants to use with confidence.
Outcome
Live at quickfinance.tools with 5+ free calculators covering the most common financial decisions for independent earners. Indexed and ranking for freelance finance keywords across US and European search markets. Monetised with AdSense to cover running costs while remaining fully free for users.
