Begin with the problem you are solving, not your preferred technology. Which people will use it day to day, with what frequency, custom development insights and how to choose a software development company is the job done today? A vendor who knows what you are trying to achieve can propose a simpler way to reach it; one who only sees the requirements as given prices exactly what you asked for.

Set out the scope as concrete flows: a walk through each important path. Just as important, state explicitly what the first release deliberately excludes. An explicit list of exclusions removes more argument during acceptance than almost anything else in the document. Mark too which decisions are settled and which may still change — the difference changes the price, and pretending everything is fixed helps nobody.

Write down the hard constraints. This means systems you must integrate with, the data you have and where it lives, compliance requirements, user volumes, target platforms and infrastructure that is already decided.
