The biggest cost driver is rarely the technology stack — it remains uncertainty. Every open question in the brief is converted into padding in the estimate. A supplier that does not know the exceptions and edge cases has to assume the worst. Investing a few days in a proper discovery often reduces the overall figure far more than any rate negotiation.
Third-party integrations tend to be the next major multiplier. A form that saves data is low risk; the same functionality wired into an old accounting system is a different problem. The cost lives in the other system: rate limits and sandbox access, long certification processes, fields that mean something different on each side. Ask any vendor app store optimization company to break integrations out as separate items, since this is where estimates break.
The requirements nobody writes down silently change the estimate. An application used by twenty people has almost nothing in common with the same functionality handling thousands of external customers. Security reviews, uptime targets, performance under load, audit logging and localisation all add measurable effort. State them early or else expect the estimate to move later.
Who actually does the work changes the arithmetic. A rate card tells you very little on its own: a senior engineer at a premium rate is often cheaper per delivered feature than a pair of junior developers who need supervision and rework. Also ask which roles are billed: coordination, testing, DevOps and UX design are real work, but they should be named rather than hidden inside a blended rate.
The number in the proposal is rarely the full cost of ownership. Expect infrastructure, subscriptions and licences, observability and a maintenance allowance for rust development agency every year the software runs. A common working assumption holds that any production system consumes a meaningful share of its original build cost every year in fixes, updates and small changes. Ignoring this remains the most common budgeting mistake.
