The single largest cost driver is not the technology stack — it remains uncertainty. Every open question in the requirements becomes a contingency in the estimate. A vendor that has no visibility into the edge cases must assume the worst. Spending a week on requirements work frequently cuts the final cost much more than any rate negotiation.
Connections to other systems remain the second big multiplier. A screen that writes to your own database is easy to estimate; the same screen wired into an old accounting system is another matter entirely. The effort hides in the other system: rate limits and sandbox access, slow approval cycles, fields that mean something different on each side. Ask each bidder to list every external system, since that is where the numbers slip.
Non-functional requirements quietly rewrite the estimate. A tool used by a small internal team is a very different build from the same functionality handling a hundred thousand users. Security reviews, availability guarantees, scalability, traceability and localisation each add weeks of work. Put them in the brief or rust consulting services else expect them priced as extras.
