I built Rinto because I was that freelancer. No contracts before starting work, invoices sent late, payments never followed up, client files scattered across email threads. I didn't even know if what I was charging was worth it because I never tracked the time I spent. Excel can technically handle all of this, but it takes forever to set up and never really feels like a business. I wanted freelancers and small agency owners to actually feel like they're running one. Because they are.
