A business owner doesn't need expensive software to manage processes and stay organized. A whiteboard or notebook often works just fine. The software industry markets solutions to problems you might not actually have.
Being organized as a business owner does not mean you need fancy software. In fact, most of the things you need to be process driven can be done on a whiteboard or in a notebook. Yeah, it's nice to have it be digital, but you don't need to be spending 100, 300, $500 a month on a tool just to keep you organized. The only reason people believe that and why that rumor and that myth is so popular is because there is a lot of money in software companies advertising to you, telling you you need our fancy proprietary software in order to systemize your business. Which is utter bull. That's why.
