Start with the problem you are solving, not a feature list. Who will use it day to day, how often, and what happens today? An estimator who understands the goal can propose a cheaper route to it; a in house team vs outsourcing costs that receives only a feature list can only price the list as written.
Set out the scope as short scenarios: who does what, and what happens next. Equally important, .net vs laravel state explicitly what you are not building. An explicit exclusion list removes more argument at delivery time than the rest of the brief combined. Indicate as well which parts are firm and which may still change — honest teams price those differently, and hiding it outsourcing uk only hurts you.
Write down the hard constraints. These include the platforms and services involved, the data you have and where it lives, regulatory obligations, traffic expectations, target platforms and stacks you cannot change. Where a date is genuinely fixed, explain what drives it: a team will often cut the right scope to meet it, but not if the date is a secret.
Write down what the word done means for the important items. Acceptance criteria do not need any formal notation: a short paragraph stating the expected behaviour is enough. This single habit shortens acceptance testing by a surprising margin and removes most late-stage disagreement.
Finally, ask for a specific format. Request an itemised estimate, the assumptions behind each number, whatever the team considers risky and a low number and a high number. Take a broad range as a signal about the brief: it normally identifies exactly which requirement is unclear. From there tighten that section and request a revised number — the revised figure will be the one worth planning around.
