The dominant factor is never the choice of framework — it is unclear scope. Every ambiguity in the requirements becomes a buffer inside the number you receive. A vendor that has no visibility into the exceptions and edge cases has to assume the worst. Spending a week on requirements work often reduces the overall figure far more than any rate negotiation. Integrations remain the second big multiplier. A screen that writes to your own database is low risk; the same screen talking to a payment provider and a CRM is not. The unknown lives in the other system: undocumented APIs, waiting on someone else's team, fields that mean something different on each side. Ask any vendor to list every external system, as this is the usual source of overruns. Quality attributes can easily double the budget. An application used by twenty people costs far less than the same idea serving a hundred thousand users. Security reviews, high availability, performance under load, traceability and multi-language support all add real engineering time. Put them in the brief or expect them to arrive later as change requests. The mix of people behind the number matters. An hourly rate reveals almost nothing on its own: one senior [https://webparadox.com/hire/angular-developers/ hire angular developer] at a premium rate is often cheaper per delivered feature than two inexperienced developers who need constant review. Ask as well who else is billed: coordination, quality assurance, infrastructure work and design have to be done by someone, but they should be named rather than hidden inside a blended rate. The build price is never the total cost.
