Side income feels great until you realize you can't tell if the hustle is netting you $800 or $200 after costs. FinTrack separates your income streams and expense categories so you can see what each hustle actually earns — not just grosses.

The side hustle finance problem
Most side hustlers track revenue but not true profit. Without separating income sources and capturing every expense, you can't make good decisions about which hustle to scale and which to drop.
You made $1,400 from your side hustle this month. But after Etsy fees, shipping supplies, packaging, and the tools you pay for — was it actually $900? $600? Most side hustlers genuinely don't know.
Both incomes hit the same bank account. By end of month, you can't tell which category of spending came from which income source. Tax season becomes a detective exercise.
Platform subscription fees, materials, software licenses, advertising spend — side hustle expenses are scattered across multiple accounts and irregular in timing.
If you're working 10 extra hours a week on a side hustle that nets $200/month after expenses, that's $5/hour. That calculation is hard to see when revenue and costs aren't tracked cleanly.
How FinTrack helps
Create distinct income categories for your main salary and each side income stream. See both totals on the same dashboard — clearly separated, never mixed.

Manual entry builds the discipline of capturing every business cost. The $12 domain renewal, the $9 design tool, the $30 supplies order — logged immediately, they add up to meaningful deductions. Forgotten, they just disappear.
FinTrack makes this feel lightweight. Quick-add on mobile means you log the expense while the receipt is still in your hand, not three weeks later when you're scrambling before the quarterly estimate deadline.
