The biggest cost driver is not the technology stack — it remains unclear scope. Every ambiguity outsourcing vs in house development the specification becomes padding somewhere in the quote. A vendor that does not know what happens on the unhappy path has to assume a pessimistic case. Investing a few days in a proper discovery often reduces the overall figure much more than haggling over hourly rates.
Third-party integrations remain the next major multiplier. A screen that writes to your own database is low risk; the same functionality wired into an old accounting system is not. The effort hides in the counterparty: rate limits and sandbox access, long certification processes, inconsistent data. Ask any vendor to list every external system, as this is where estimates break.
The requirements nobody writes down silently change the estimate. A tool used by a handful of staff has almost nothing in common with the same idea serving thousands of external customers. Audit and compliance requirements, uptime targets, scalability, traceability and accessibility add weeks of work. Put them in the brief or else expect them to arrive later as change requests.
Who actually does the work changes the arithmetic. An hourly rate says almost nothing on its own: a senior engineer at a premium rate frequently turns out to be cheaper per delivered feature than a pair of junior developers who require heavy code review. Ask as well which roles are billed: delivery management, testing, infrastructure work and UX design are real work, but these should be itemised.
The number in the proposal is never what you will actually spend. Plan for cloud costs, third-party licences, monitoring and an ongoing support budget for every year the industry specific software development runs. A common working assumption is that software in active use consumes a recurring percentage of its original build cost per year in fixes, updates and small changes. Ignoring this remains the most frequent planning error.
