Question to freelancers: do you ever have a dispute over hours you bill?
As IndieHackers, we have a long-term vision of our dream product but have to start somewhere and only build a little piece of it. Are you keeping track of what you develop (and what you plan to get to later) in some way? Trello boards? Notebooks? Prototypes? Or keep everything in your head?
Related question, if you delegate tasks, what do you use to keep those in order?
