Open with the business problem, vue js vs angular 2 not a feature list. What kind of user will use this, how often, and what does the process look like without it? An experienced team who understands the goal often proposes an alternative that costs less; a team that receives only the requirements as given prices the list as written.
Describe the scope as concrete flows: who does what is livewire, and what happens next. Equally important, write down what is out of scope. An explicit list of exclusions prevents more friction at delivery time than almost anything else in the document. Indicate as well which decisions are settled and which are still open — estimators price uncertainty, difference between livewire and react and concealing the open questions only hurts you.
Write down the hard constraints. The list covers existing systems the software has to talk to, the data you have and where it lives, compliance requirements, user volumes, supported browsers or devices and stacks you cannot change. If a deadline is real, say why mvps fail: a team can often cut the right scope to hit it, but not if the date is a secret.
Say what completion means for the important items. Clear acceptance criteria do not need any formal notation: a plain-language note setting out the expected behaviour is sufficient. That one addition reduces the review at the end dramatically and removes the most common source of disputes.
One last thing, say what you expect back. Request a breakdown by feature or module, the assumptions behind each number, the risks the team sees and a low number and a high number. Treat a wide range as a signal about the brief: it normally identifies exactly which requirement is unclear. At that point rewrite that part and ask for a new estimate — the next version is the one worth planning around.
