Open with the problem you are solving, edtech software development not a feature list. What kind of user will use this, with what frequency, and what does the process look like without it? A vendor who grasps the purpose will suggest an alternative that costs less; one who only sees a list of screens will price your assumptions along with the work.

Define what is included as concrete flows: a walk through each important path. Equally important, write down what the first release deliberately excludes. An explicit exclusion list removes more disagreement at delivery time than almost anything else in the document. Mark too which items are decided and which are still under discussion — the difference changes the price, and hiding it only hurts you.

Write down the hard constraints. These include existing systems the software has to talk to, the data you have and where it lives, security and compliance rules, user volumes, supported browsers or devices and stacks you cannot change. If there is a hard date, explain what drives it: a team can often resequence the work to hit it consulting services, but not if the date is a secret.

Write down what completion means for each item. Testable acceptance criteria need not use special syntax: a short list setting out what must be true when the feature works will do. That one addition shortens acceptance testing considerably and closes off the usual argument at handover.

To close, flutter consulting services say what you expect back. Request a task-level breakdown, the assumptions behind each number, whatever the offshore development team for saudi arabia considers risky and an optimistic and a pessimistic figure. Read a wide range as information, not evasion: it tells you the part of the brief that needs work. From there rewrite that part and request a revised number — the second estimate will be much more reliable.
