Begin with the problem you are solving, not your preferred technology. What kind of user will use this, with what frequency, and what does the process look like without it? An estimator who understands the goal often proposes a cheaper route to it; a team that receives only a feature list will price your assumptions along with the work.

Describe the scope as user stories php or python scenarios: a walk through each important path. Just as important, write down what is out of scope. An explicit list of exclusions prevents more disagreement later than almost anything else in the document. Also mark which parts are firm and which may still change — the difference changes the price, and flutter development agency pretending everything is fixed helps nobody.

Write down the hard constraints. The list covers systems you must integrate with, the data you already hold and custom angular development its condition, compliance requirements, expected load, which devices matter and infrastructure that is already decided. If there is a hard date, say what depends on it: an experienced team is usually able to cut the right scope to hit it, provided they hear about it early.

Define what done means feature by feature. Acceptance criteria do not need any formal notation: a short paragraph setting out what must be true when the feature works will do. This single habit shortens the sign-off process dramatically and removes the usual argument at handover.

One last thing, ask for a specific format. Ask for an itemised estimate, the assumptions used, the main risks and an optimistic and a pessimistic figure. Read a wide range as useful information rather than evasion: it normally identifies exactly which requirement is unclear. At that point tighten that section and ask again — the next version will be much more reliable.
