The dominant factor is not the choice of framework — it is unclear scope. Every open question in the requirements becomes a contingency in the estimate. A team that does not know the exceptions and edge cases must assume the worst. Putting two weeks into a proper discovery can cut the total by far more than haggling over hourly rates.

Connections to other systems are the next major multiplier. A form that saves data is low risk; the same functionality wired into a payment provider and a CRM is not. The unknown hides in the other system: undocumented APIs, slow approval cycles, data that does not match your model. Ask each bidder to list every external system, as this is the usual source of overruns.

Quality attributes silently change the number. A tool used by twenty people is a very different build from the same functionality serving a hundred thousand users. Audit and compliance requirements, high availability, load handling, traceability and multi-language support all add weeks of work. Write them down at the start or else expect them to arrive later as change requests.

The mix of people behind the number matters. A rate card says almost nothing on its own: an experienced engineer at twice the price is often cheaper overall than a pair of junior hire dedicated python developers who need constant review. Ask as well what else appears on the invoice: delivery management, quality assurance, release engineering and analysis are real work, but they must be itemised.

The build price is not the full cost of ownership. Expect infrastructure, third-party licences, monitoring and an ongoing support budget annually. A useful planning figure is that custom software development services in active use requires a meaningful share of its original build cost per year simply to stay current. Ignoring this has always been the most common budgeting mistake.
