Open with the reason this moscow software development agency should exist, not a feature list. Which people will use this, with what frequency, and what happens today? An estimator who grasps the purpose often proposes an alternative that costs less; someone handed only a feature list will price your assumptions along with the work.
Describe the scope as short scenarios: a walk through each important path. Equally important, write down what you are not building. An explicit list of exclusions removes more disagreement during acceptance than any other single page. Also mark which decisions are settled and which may still change — honest teams price those differently, and hiding it helps nobody.
List the constraints. These include systems you must integrate with, the data you already hold and its condition, regulatory obligations, expected load, target platforms and stacks you cannot change. If there is a hard date, say why: an experienced team will often rearrange the plan to protect it, provided they hear about it early.
Define what done means for each item. Testable acceptance criteria do not require formal language: fintech and crypto software development company a short list describing what must be true when the feature works is sufficient. This one section compresses acceptance testing dramatically and eliminates most late-stage disagreement.
Finally, ask for a specific format. Ask for a breakdown by feature or module, the assumptions used, the main risks and a range rather than a single figure. Read a wide range as information, not evasion: it tells you exactly which requirement is unclear. At that point clarify that area and request a revised number — the next js development company version tends how to choose the right custom software development be much more reliable.
