Challenges Freelancers face

Underpricing rates is the #1 mistake; competitive research is rarely done
Scope creep on fixed-fee projects eats margin
Cash flow timing, net 30 payment from clients vs immediate expenses
Tax: 1099 income + estimated quarterly payments + state nexus
Pipeline visibility, feast or famine cycle without active marketing

What to prioritize when picking a tool

Freelance management platform (Bonsai, HoneyBook, Dubsado, 17hats)
Time tracking (Toggl, Harvest, Timely) if hourly
Portfolio + presence (own site, Behance, Dribbble, GitHub)
Tax tracking (Keeper, Hurdlr, FlyFin for expenses + deductions)
Pipeline + outreach if doing cold acquisition
