The biggest cost driver is rarely the technology stack — it is almost always uncertainty. Every open question in the requirements is converted into padding in the estimate. A vendor that does not know what happens on the unhappy path will assume the more expensive option. Spending a week on requirements work can cut the total by far more than negotiating the rate.
Third-party integrations tend to be the second big multiplier. A screen that writes to your own database is low risk; the same functionality wired into a payment provider and a CRM is a different problem. The unknown hides in the other system: poor documentation, waiting on someone else's team, inconsistent data. Ask each bidder to list every external system, since this is the usual source of overruns.

Compliance work, high availability, nearshore software development load handling, data retention rules and multi-language support all add weeks of work. State them early or expect the estimate to move later.
