The dominant factor is never technology — it remains unclear scope. Every open question in the requirements is converted into a contingency in the estimate. A vendor that has no visibility into what happens on the unhappy path has to assume the more expensive option. Putting two weeks into a discovery phase frequently cuts the final cost by far more than negotiating the rate. Integrations tend to be another reliable source of cost. A screen that writes to your own database is predictable; the same functionality talking to a legacy ERP is another matter entirely. The unknown hides in the third party: poor documentation, long certification processes, data that does not match your model. Ask the estimator to price integrations separately, as this is the usual source of overruns. Non-functional requirements can easily double the estimate.
