The dominant factor is rarely technology — it remains how much is still undecided. Every open question in the brief is converted into padding in the estimate. A team that cannot see the edge cases has to assume the more expensive option. Investing a few days in a proper discovery can cut the overall figure much more than any rate negotiation.

Connections to other systems are the second big multiplier. A form that saves data is predictable; the same functionality connected to an old accounting system is not. The cost lives in the third party: undocumented APIs, fintech software development waiting on someone else's team, inconsistent data. Ask the estimator to list every external system, since this is where estimates break.

Non-functional requirements quietly rewrite the budget. An application used by a handful of staff has almost nothing in common with the same feature set serving public traffic. Audit and compliance requirements, uptime targets, scalability, audit logging and multi-language support add measurable effort. Write them down at the start or else expect the estimate to move later.

The team you are quoted matters. A day rate tells you little on its own: an experienced engineer at twice the price is often cheaper overall than two inexperienced developers who need supervision software maintenance and support services rework. Also ask which roles are billed: project management, QA, DevOps and analysis are legitimate costs, but they should be visible in the estimate.

The quoted figure is not the total cost. Budget for cloud costs, third-party licences, observability and an ongoing support budget each year. A useful planning figure is that a live system consumes a recurring percentage of the initial investment per year for updates, security patches and small improvements. Leaving it out of the budget has always been the most common budgeting mistake.
