Fixed scope or monthly: which fits?
Fixed scope works when what you need is written down and stable. That is why every build starts with a written scope: you sign off milestones one at a time, and you know the price before work starts.
A monthly contract works once you are live and learning from users, when next month's priorities are not knowable today. It covers iteration, refactoring and scaling, and starts after a scoping conversation about what the month should include.
Not sure yet? Most founders start with a fixed-scope build and move to a monthly contract after launch. Read how a project runs, week by week.
