The dominant factor is rarely technology — it remains how much is still undecided. Each unanswered question in the brief turns into padding in the estimate. A vendor that has no visibility into the edge cases has to assume the more expensive option. Putting two weeks into a discovery phase frequently cuts the final cost far more than any rate negotiation. Connections to other systems tend to be another reliable source of cost. A form that saves data is low risk; the same feature talking to a legacy ERP is another matter entirely. The cost lives in the other system: rate limits and sandbox access, waiting on someone else's team, data that does not match your model. Ask any vendor to list every external system, since this is the usual source of overruns. Non-functional requirements can easily double the budget. An internal tool used by a small internal team has almost nothing in common with the same feature set serving public traffic.

The number in the proposal is never the total cost. Plan for hosting, paid APIs, observability and an ongoing support budget annually. A reasonable rule of thumb says that a live system consumes a meaningful share of the initial investment annually for [https://webparadox.com/industries/government/ custom app development tool for state governments] updates, security patches and small improvements. Ignoring this is the most frequent planning error.
