Start with the reason this software should exist, not a feature list. What kind of user will use the system, how often, and what happens today? A vendor who understands the goal can propose a simpler way to reach it; someone handed only the requirements as given can only price exactly what you asked for.
Define what is included as short scenarios: who does what, and what happens next. Equally important, write down what the first release deliberately excludes. build an mvp explicit list of exclusions saves more disagreement during acceptance than the rest of the brief combined. Mark too which parts are firm and which are still under discussion — estimators price uncertainty, and concealing the open questions helps no one.
Set out your constraints. The list covers the platforms and services involved, the data you have and where it lives, compliance requirements, expected load, supported browsers or devices and stacks you cannot change. If a deadline is real, explain what drives it: an experienced team can often cut the right scope to meet it, mobile app development services but not if the date is a secret.
Say what completion means for the important items. Acceptance criteria do not need special syntax: a plain-language note setting out the expected behaviour is enough. This one section compresses acceptance testing dramatically and removes the usual argument at handover.
Finally, state what you want in house team vs outsourcing costs the response. Require an itemised estimate, a written list of assumptions, whatever the team considers risky and a low number and a high number. Read a wide range as information, not evasion: it tells you the part of the brief that needs work. Then tighten that section and ask again — the second estimate is much more reliable.
