Every ambiguity in the brief turns into padding somewhere in the quote. A supplier that has no visibility into the edge cases must assume the more expensive option. Spending a week on requirements work can cut the overall figure much more than haggling over hourly rates.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Integrations are the second big multiplier. A screen that writes to your own database is low risk; the same feature connected to an old accounting system is a different problem. The cost lives in the other system: rate limits and sandbox access, waiting on someone else&amp;#039;s team, fields that mean something different on each side. Ask each bidder to price integrations separately, because this is the usual source of overruns.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Non-functional requirements silently change the budget. A tool used by a small internal team is a very different build from the same idea handling thousands of external customers.

State them early or you can expect the estimate to move later.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;The mix of people behind the number changes the arithmetic.
