Begin with the business problem, not a list of screens. Which people will use the system, how many times a day, and what does the process look like without it? An estimator who understands the goal often proposes a simpler way to reach it; someone handed only a list of screens prices exactly what you asked for.
Set out the scope as short scenarios: what the user does and what the system does in response. Every bit as useful, state explicitly what you are not building. An explicit exclusion list saves more argument later than any other single page. Also mark which parts are firm and which are still open — the difference changes the price, custom crm and erp automation solutions free development estimate concealing the open questions helps nobody.
List the constraints. These include the platforms and typescript development services involved, existing databases and custom real estate software development their quality, security and compliance rules, expected load, target platforms and stacks you cannot change.

Define what completion means for each item. Clear acceptance criteria need not use special syntax: a plain-language note stating what must be true when the feature works is sufficient. That one addition reduces acceptance testing considerably and removes the most common source of disputes.
One last thing, ask for a specific format. Request a task-level breakdown, the assumptions used, the risks the team sees and a low number and a high number. Take a broad range as a signal about the brief: it usually points to where your description is thin. From there clarify that area and ask again — the next version is much more reliable.
