The dominant factor is never the technology modern web development stack — it is almost always how much is still undecided. Each unanswered question in the brief becomes a contingency in the estimate. A team that does not know what happens on the unhappy path must assume the worst. Spending a week on a discovery phase frequently cuts the final cost far more than any rate negotiation.
Third-party integrations are the next major multiplier. A form that saves data is easy to estimate; the same feature connected to a payment provider and a CRM is not. The effort hides in the third party: rate limits and sandbox access, waiting on someone else's team, fields that mean something different on each side. Ask the estimator to list every external system, since this is the usual source of overruns.

A tool used by a handful of staff has almost nothing in common with the same idea serving a hundred thousand top golang development companies users. Security reviews, high availability, scalability, data retention rules and multi-language support add real engineering time. Write them down at the start or else expect them to arrive later as change requests.
