Start with the business problem, not a feature list. Who will use this, with what frequency, and what happens today? An experienced team who knows what you are trying to achieve can propose a cheaper route to it; someone handed only the requirements as given can only price your assumptions along with the work.

Set out the scope as user stories or scenarios: a walk through each important path. Equally important, state explicitly what is out of scope. An explicit list of exclusions prevents more friction later than almost anything else in the document. Mark too which items are decided and which are still open — the difference changes the price, and concealing the open questions only hurts you.

List the constraints. These include existing systems the software development quote has to talk to, existing databases and their quality, regulatory obligations, user volumes, which devices matter and igaming software developer infrastructure that is already decided. If there is a hard date, say what depends on it: a good team can often rearrange the plan to protect it, provided they hear about it early.

Say what done means for the important items. Clear acceptance criteria do not require any formal notation: a short list stating the expected behaviour will do. That one addition shortens acceptance testing considerably and closes off the most common source of disputes.

Finally, ask for a specific format. Require an itemised estimate, the assumptions used, the main risks and an optimistic and a pessimistic figure. Take a broad range as useful information rather than evasion: it tells you exactly which requirement is unclear. Then clarify that area and request a revised number — the second estimate will be much more reliable.
