Keeper

Keeper is a mobile-first app focused exclusively on helping freelancers find tax deductions and track expenses. It scans transactions, identifies write-offs, and prompts you to capture receipts. It's less a full accounting suite and more a smart tax assistant that ensures you don't miss any deductible expenses, from home office to phone bills. It also helps estimate quarterly taxes and prepare 1099 forms.

For solopreneurs who find full accounting software overkill but want rigorous, automated deduction tracking to maximize tax savings, Keeper is a perfect complementary tool. It simplifies the most financially impactful part of freelance finance.
