Invoicing and real budgeting for your business, debt payoff and bill tracking for your life — one place for both, built for freelancers and solo operators, not an enterprise team you don't have.
A day job, a full-time business, a side hustle on top of both — most people's money doesn't come from just one place, so FinnLion doesn't make you split it across three apps. Every dollar in and out gets tagged business or personal, your budget sees the whole picture regardless of where income comes from, and your quarterly tax estimate knows the difference between a paycheck that's already been taxed and freelance income that hasn't.
Invoices & Estimates
Branded invoices and estimates, with quotes that convert straight into an invoice.
Real Budgeting
Monthly budgets that roll over and auto-populate from your bills — not just a spending list.
Built for Side Hustles
Freelance work, rideshare driving, a shop on the side — run it as its own business right next to your day job, not a second account you have to juggle.
Debt Payoff Tracking
Track credit cards and loans, watch balances shrink, and see what's due before it's late.
Bill Fluctuation Tracking
See a bill creeping up before it becomes a problem, month over month.
Mileage Tracking
Log the drive and let the standard IRS rate turn it into a deduction automatically.
Bank Sync
Connect your bank and transactions import automatically, ready to categorize.
Business & Personal, Split Cleanly
Every transaction sorts into business or personal — and if it's a paycheck that's already had tax withheld, mark it so your estimate doesn't count it twice.
Quarterly Tax Estimates
A running estimate of what to set aside, right from your own numbers.
