The dominant factor is not the technology stack — it is uncertainty. Every open question in the brief is converted into a contingency somewhere in the quote. A vendor that cannot see the edge cases has to assume a pessimistic case. Spending a week on a discovery phase frequently cuts the total much more than haggling over hourly rates.
Connections to other systems tend to be another reliable source of cost. A form that saves data is predictable; the same feature connected to a payment provider and a CRM is another matter entirely. The cost hides in the counterparty: rate limits and sandbox access, slow approval cycles, data that does not match your model. Ask the estimator to price integrations separately, as this is where estimates break.
