Begin with the reason this software should exist, not a list of screens. Which people will use it day to day, how many times a day, and what happens today? An estimator who grasps the purpose will suggest an alternative that costs less; a team that receives only a feature list prices your assumptions along with the work.

Define what is langchain a rag framework included as short scenarios: who does what, and what happens next. Just as important, write down what you are not building. An explicit list of exclusions removes more disagreement during acceptance than any other single page. Mark too which decisions are settled and which are still under discussion — honest teams price those differently, and hire mypos developers pretending everything is fixed helps nobody.

Set out your constraints. The list covers existing systems the software has to talk to, the data you already hold and its condition, compliance requirements, user volumes, which devices matter and infrastructure that is already decided. Where a date is genuinely fixed, say what depends on it: a team can often rearrange the plan to meet it, but not if the date is a secret.

Define what done means feature by feature. Acceptance criteria do not require special syntax: rest vs graphql comparison a plain-language note stating what a user should be able to do will do. This single habit shortens the sign-off process by a surprising margin and eliminates the usual argument at handover.

Finally, state what you want in the response. Request a breakdown by feature or module, a written list of assumptions, whatever the team considers risky and a range rather than a single figure. Treat a wide range as useful information rather than evasion: it tells you exactly which requirement is unclear. From there clarify that area difference between monolith and microservices ask for a new estimate — the revised figure will be much more reliable.
